Its mission is to provide cleaner air for our customers so they can live longer, healthier, and happier.

Medify Air MA-40 Air Purifier Review

Medify Air MA-40 Features And Build Quality

The top-of-the-line in its class, the newer version 2.0 Medify Air MA-40 air purifier is the latest rendition with improved features and a higher-grade HEPA H13 filter. House in modern and highly versatile that can be used anywhere in the room. It is relatively slim at 9.9 inches in width, 22 inches in height, and 10.9 inches in depth. Only a tad bigger than the entry-level MA-15. While it does not merit a travel form factor, you can place it on the work desk, shelf, bedside table, or corner of the room without taking up much space. The 15.6 pounds weight is on the heavier side; however, most people will have no issue carrying it around. As for the design usability, you have a big horizontal air inlet that can pull air in from the lower ground and distribute clean air right at the top. The removable panel is magnetically fitted and can easily be removed for a quick filter change. Overall, the body is made mainly with glossy, high-quality plastic that feels more premium than the material suggested. Medify MA-40 is very well-built, and we have not spotted any misalignment, off-gassing, or patchy spot.

Medify Air MA-40 control panel

Navigating Medify MA-40 could not be any easier. The capacitive touch tempered glass panel comes with basic and advanced controls that you can make use of. Cycle the fan speed between quiet for everyday use or performance to counter unhealthy indoor air quality. The child lock prevents any unintended adjustment of the controls by tapping on the button for 2-5 seconds. The timer comes with a 1, 2, 4, or 8 hours timer preset that can be set to turn off the air purifier. You can also disable the ionizer function or dim the light button to reduce glare at night. Lastly, the passive filter replacement indicator will remind you to change the filter after 2,500 hours of runtime.

To round up Medify Air MA-40 passive features, it is ozone-safe as approved by CARB (California Air Resources Board), non-AHAM tested on CADR, international UL safety standard, ETL quality tested, and Energy Star certified. The renowned Medify lifetime warranty also covers any manufacturer defects for the rest of your life, providing original Medify filters are replaced on time and no third-party filters are used.

Medify Air MA-40 Filtration, Air Performance, And Noise

Smack in between MA-112 and MA-50. Here's what has been upgraded in Medify MA-40. It can cover up to 336 square feet of room space for a heavily polluted area at 5 air changes per hour. For asthmatic sufferers that need quick air cleaning, expect a lower 420 square feet of coverage at 4 air changes per hour (15 minutes). For general use, the air purifier can consistently cover up to 840 square feet at 2 air changes per hour (30 minutes). Unless you have sensitive lungs that need the highest air exchanges, Medify MA-40 will do well in the living room, big bedroom, garage, basement, lounge, nursery home, or any large spaces in a residential home. Auto mode is the only surprise omission in this top-tier model.

The clean air delivery rate measures the speed of an air cleaner to remove specific particulates in a fixed environment. Medify MA-40 CADR reflects well on the increased airflow delivery rate. Under the official guidelines, dust, pollen, and smoke CADR averages 224 cubic feet per minute or 380 cubic meters per hour (m³/h). Safe to say, Medify Air MA-40 passes our 200 cfm benchmark with flying colors.

Here are the key differences between Medify Air MA-40 and the rest of its lineup. Outfitted with a dual intake 4-stage air filtration, the outer pre-filter traps large particles, mainly dust, hair, fibers, lint, and protect the HEPA filter from getting clogged. With most large particles removed, the dual H13 HEPA filter removes 99.9% of irritants as small as 0.1 microns e.g. dust mites, mold, pollen, pet dander, bacteria, and virus carrier. 0.12 to 0.25 microns is the most penetrating particle size (MPPS) through a filter. For smoke particles, you have the honeycomb carbon filter with carbon pellets that absorb pet odors, cooking smells, musty mold, tobacco smoke, and harmful toxins e.g. VOCs, asbestos, formaldehyde, and benzene. As with the attached pre-filter, the composite filter is not washable and requires every 6 months. An optional ionizer technology (which can be disabled) diffuses negative ions that will latch to nearby positive ion particles in the air. Subsequently, the particles will fall from the increased weight, and Medify Air MA-40 will pull the pollutants into its filtration.

Overall, the filter quality is great, but the dual filter setup can be costly and a hassle to replace. For those suffering from hypersensitivity, asthma, or are allergic to dust particulates in the air, Medify Air MA-40 air purifier will significantly improve your health condition.

Medify Air MA-40 filter

Medify MA-40 noise output is split between its fan base. Some find the noise acceptable for all-day use, while some find it loud and distracting. At low speed, AKA "Sleep mode," the noise level is at 46 dBA, which is in white noise territory. At max speed, the noise level could go as high as 66 dBA, which is as loud as a vacuum cleaner. So if you want to use the air purifier during sleep or a focus session, stay clear of high speed. The V2.0 will automatically turn off the ionizer to make it quieter, but you can enable it back when needed.

For power consumption, Medify Air MA-40 is Energy Star rated with an average of 54 watts per hour. More than triple MA-15 monthly energy consumption, but you have to remember this is a way more powerful unit. With 12 hours of runtime, the estimated cost is around $0.10 per day, $2.9 per month, or $35 per year. Pretty efficient as a mid-range air purifier. For 24 hours runtime, multiply the electric cost by 2. The energy cost will vary depending on the local energy rate, fan speeds, and operational hours.

Medify Air MA-40 Pricing, Maintenance, And Drawbacks

Medify Air MA-40 air purifier might not be the most expensive model in its lineup; the specification and performance justify its overall cost. It is well-built, uses premium materials, and has dual filtration for extra air cleaning capacity. The default H13 HEPA filter is a nice touch to stand out from competitors' models. On the flip side, the additional filtration will cost you extra in the maintenance, especially with the short 2500 hours (3-6 months) filter lifespan. You will have to fork out around 120 dollars annually to ensure the pristine condition of Medify MA-40. While third-party filters are available, doing so will void the lifetime warranty. Keep this in mind.

Medify Air MA-40 air purifier

As for the drawbacks, fan noise is a common complaint but not the end of the world. The lack of sensors, AQI, and auto mode is a miss, but the filter cost is the biggest hindrance. Expect to pay close to $120 annually to replace the pre-filter, HEPA, and carbon filter. If you are OK with all that, Medify MA-40 will be a well-received air purifier with strong filtration performance. Your allergy symptoms, like cough, sneezing, and red eyes, will be a thing of the past.

2. Medify Air MA-25 Air Purifier

Medify Air MA-25 Air Purifier Review

Medify Air MA-25 Features And Build Quality

Love MA-15 but wish the coverage could be a little bit better? In comes Medify Air MA-25. A compact HEPA air cleaner that is even smaller than the lower-tier MA-15. Medify MA-25 is a sleek and modern air purifier that stands at only 13.5 inches in height and 8 inches in diameter. It will fit virtually any place well without obscuring your floor space. The 7.3 lb weight makes it easy to carry around for room-to-room-purifying. Great for those that only have 1 air purifier in their home and have no plan of getting another one. Available in black or silver, the 360° air inlet design not only enhances the appearance but will also serve a functional purpose so more particles can be captured in one go. Build quality is superb, as always coming from the brand. No signs of poor fitting or off-gassings which can be a common theme in a budget air cleaner.

Moving on to the top controls located next to the air outlet. You have a dedicated power-off button and a fan speed button that cycles between the 3 speeds. The child safety lock button locks the setting to prevent children from messing with it. A timer button allows you to set a time to down the air purifier. There is also a light button that dims down the indicator light. Lastly, a LED filter replacement indicator will alert you to change the filter after 2,500 hours or every 3-4 months.

Medify Air MA-25 has all the bells and whistles despite its low price. It is ozone-safe, CARB approved, UL listed, and comes with Medify Air lifetime warranty (register within 30 days of purchase). It covers everything from manufacturing defects and poor workmanship with the use of a genuine Medify Air filter and replacement in accordance with the suggested timeline.

Medify Air MA-25 Filtration, Air Performance, And Noise

Here's why you should upgrade to Medify Air MA-25 instead of MA-15. It can reach up to 500 square feet of room size at 2 air changes per hour or every 30 minutes. Double the coverage to 1000 square feet for 1 ACH or clean air every 60 minutes (not recommended). To get the best out of Medify Air MA-25, run it at full speed with 4 air changes per hour for a reduced 250 square feet of purifying coverage. No Auto mode here, as with most of the budget air cleaners.

CADR measures how fast an air cleaner can remove particulates in a room under a controlled environment. As such, Medify MA-25 CADR is reasonable for a small air purifier priced under $150. While the 135 cubic feet per minute (CFM) for dust, pollen, and smoke did not exceed our benchmark of 200, it will work well in small to medium room sizes. You can place it on a cabinet or nightstand in a bedroom, kitchen, dining hall, walk-in wardrobe, or studio office.

The perfect model for an asthmatic or allergenic person. Medify Air MA-25 air purifier uses a 100% ozone-free, multi-layer filtration with a dual intake. It will capture airborne contaminants from both sides. The internal fan will pull air in from both sides, allowing the pre-filter to trap large particles like dust, hair, pet fur, and lint from passing through. It will also protect the dense True HEPA filter usage life from being damaged by sharp particulates. The excellent medical-grade HEPA filter removes 99.9% of allergens as small as 0.1 microns e.g. dust mites, mold, pollen, pet dander, bacteria, and viruses. Far superior to your typical true HEPA or HEPA-type filter. The carbon filter with carbon pellets absorbs smoke and odor from cooking smells, cigarette smoke, pet, and toxic fumes, including VOCs. Filter quality is top-notch in removing airborne allergens. For those stuck in an unhealthy air environment, you can feel the differences in air quality after using Medify Air MA-25 in a matter of days.

Medify Air MA-25 runs at a whispering 35 decibels noise output if you keep it at sleep mode or low speed. It did not distract us during work or sleep, even when placed right next to us. At max speed, the fan noise is audible at 52 decibels, similar to a quiet conversation. Still usable if those that won't mind some white noise or need quick air cleaning.

Power consumption is efficient but increased from the previous MA-15. Medify MA-25 air purifier uses an average of 28 wattages of energy hourly. Low compared to other household appliances like an oven, air-con, and refrigerator. You can use it continuously for months and will barely see any changes in your energy bill. With 8 hours of day-to-day operation, electricity costs around $0.05 per day, $1.5 a month, or $18 a year, depending on the state's electrical rates. Multiply the electric costs by 2 if you intend to leave it on 24x7.

Medify Air MA-25 Pricing, Maintenance, And Drawbacks

For less than $150 after a discount (MRSP $199), the Medify MA-25 air purifier is a catch as long as you don't look into the filter cost (more on this later). It offers solid air cleaning performance while retaining all the features that make it what it is. Alternate options from Levoit, Winix 5500-2 offer stronger airflow but compromise the size and the filtration quality. If you are on the hunt for an affordable budget medical-grade air purifier, more specifically a Medify Air, do consider stepping up to MA-40 as well.

Here's where Medify MA-25 might fall short. Ignoring the lack of autonomous mode, the steep $170-228 filter is too much for a price-conscious group. The main contributor to the costly maintenance is the short 3-4 months filter life or every 2,500 hours. Third-party filter options are available, but we won't recommend those, as doing so will void Medify Air's lifetime warranty. If the filter cost is hard to chew on, Levoit models should be a better fit for you.

With more than 10,000 reviews on Amazon, Medify Air MA-25 is a top-rated air cleaner that offers exceptional value but with a slight caveat. It offers excellent build quality, medical-grade H13 HEPA filtration, solid active carbon composite, and a compact form factor for under $150. If you can handle the annual recurring fees, Medify Air MA-25 will be a great addition to your home.

3. Medify Air MA-50 Air Purifier

Medify Air MA-50 Review

Medify Air MA-50 Features And Build Quality

The new breed to its lineup, Medify MA-50 is a UV/ HEPA air purifier designed and tested to be effective against airborne particles, including COVID-19. True to Medify design elements, the sleek and modern exterior looks good at every angle. At a slim 12.4 inches diameter and a tall 24.6 inches height, You can place it anywhere in your home as long as it is left on the ground. The 16 pounds weight is a tad heavy, but moving it around is doable with a little bit of effort. The big air inlet pulls air in at the front and distributes clean air at the top air outlet. Build quality is solid, with easy-to-remove panels that can be taken out for quick cleaning. Medify MA-50 air purifier is ozone-safe as approved by CARB (California Air Resources Board), certified by international UL safety standards, ETL, and Energy Star Rated. The lifetime warranty will protect your unit for life on electronic parts and motors, providing no third-party filters are used.

Nothing spells more expensive than Medify MA-50 tempered touched glass panel. It looks premium and comes with most of the functions you ever need. Cycle between the 4 fan speeds, including night mode, or use the advanced 2 to 12 hours timer to schedule when to shut down the air purifier. The filter replacement indicator will alert you to change the filter after 2,500 hours of runtime. Other valuable features include the ability to dim the indicator light (for night use), activate/ deactivate the UV-light function, and lock the control setting from meddling children.

Medify Air MA-50 Filtration, Air Performance, And Noise

The inner motor with a fan draws polluted air into a room and forces the air through different layers of filter. It can cover 2,200 square footage of space every 60 minutes (1 ACPH), a reduced 1,100 square footage every 30 minutes (2 ACPH), and 550 square footage every 15 minutes or 4 air changes per hour. Medify MA-50 air purifiers are also tested with MS2 with an accepted surrogate of 579 cubic foot virus responsible for COVID-19. Clean air will be released back into the room, and the air-cleaning cycle will repeat itself until the air is completely purified. Medify MA-50 can be used comfortably in the living room, bedroom, garage, basement, office, nursery home, or any large space that needs air protection.

Tally with the airflow delivery rate, AHAM Clean air delivery rate measures the speed Medify MA-50 air cleaner can remove particulates in a fixed environment. Dust, pollen, and smoke CADR are averaging around 295 cfm or 500 m³/h. Way better than MA-40 but below the top tier MA-112 ratings.

Featuring an updated mechanical filtration that combines conventional filters + UV disinfection. Unlike the previous MA-40 that comes with an ionizer, Medify Air MA-50 uses four filtration layers: pre-filter, H13 True HEPA, UV light disinfection, and active carbon composite. The pre-filter captures large PM10 particles like dust, hair, fibers, and lint and protects the H13 HEPA filter. The medical-grade H13 HEPA filter will remove 99.9% of microscopic pollutants as small as 0.1 microns e.g. dust mites, mold, pollen, pet dander, asbestos, carbon dust, paint pigment bacteria, and virus carrier. The active carbon composite neutralizes pet odors, cooking smells, musty mold, common smoke, carbon dust, and harmful toxins e.g. VOCs, asbestos, formaldehyde, and benzene. UV light radiates a short wavelength that kills biological pollutants and prevents them from multiplying and spreading. It is safe and effective particular when paired with an H13 HEPA filtration. To top it off, Medify MA-50 is independently lab tested by Aerosol Research and Engineering Laboratories Inc.; in consult with Intertek Assurance, Medify MA-50 can remove 99.95% of particles related to COVID-19 & SARS-Cov-2 in the air.

Medify MA-50 air purifier is surprisingly quieter than MA-40, even though the differences are neglectable. When running at low-speed (night mode), the noise level is around 35dBA, which outputs a whispering sound at best. The high-speed 56 dBA can be distracting for some, but you will get used to it in a short amount of time. Since there is no auto mode in sight, use the lowest speed during nighttime or when you need absolute quiet. For power usage, Medify MA-50 is Energy Star rated that uses 54 watts of energy per hour. Not the most efficient unit given its strong output; you can still expect a marginally low 3-4 dollars of monthly electricity bill.

Medify Air MA-50 Pricing, Maintenance, And Drawbacks

Medify MA-50 air purifier will cost you around 300+ dollars, including comprehensive filtration. While the price is justifiable for the build quality, air filtration, and lifetime warranty, there are no built-in sensors and auto mode by default. That said, the biggest obstacle for us is the high MA-50 filter cost that requires replacing every 3 to 4 months or 2,500 hours. Expect to pay 78 to 156 dollars annually, depending on how bad the room quality is. Rather than going down the third-party filters root, there are other cheaper alternatives to go if you want an H13 air purifier with a low maintenance cost.

In conclusion, Medify Air MA-50 is a solid air purifier priced between top-tier MA-112 and MA-40. Get this if you want something that offers value in between.

4. Medify Air MA-112 Air Purifier

Medify Air MA-112 Air Purifier Review

Medify Air MA-112 Features And Build Quality

Wirecutter's pick and highest clean air delivery rate (CADR) on Amazon, Medify MA-112 air purifier has it all. The familiar clean design is surprisingly not that big, given its strong airflow performance. At a 16 x 28 x 15 inches dimension, other bigger units like IQAir HealthPro and Blueair Classic 605 take up more interior space without matching airflow output. Available in 2 colors, the side air inlets support dual air intake so airborne pollutants can be pulled in from both angles. This setup is consistent across the Medify air purifier lineup. The only downside is that the heavy 32 pounds weight makes room-to-room purifying difficult. Fortunately, there are casters wheels that help move the Medify Air MA-112 a breeze.

Medify Air Ma-112 Control Panel

Usability is another strong suit of Medify MA-112 air purifiers. It has a built-in sensor to support the AQ indicator and auto mode. The air cleaner will automatically run at a higher speed when a high concentration of pollutants is detected. There are also 4 variable speeds, 4 preset timers, an ionizer that can be switched off, and sleep mode. Under notable features include a child lock that prevents children from changing the setting and a light button that dims all indicator lights to prevent glare during sleep. Lastly, a filter replacement indicator reminds you to change the filter after 3,000 hours of runtime. Build quality is spot on with tight removable panel fitting and a premium touch control panel. No misalignment or off-gassing can be found. The only letdown is the lack of remote control or app connectivity at this price point.

Medify MA-112 comes with all the safety certifications, including CARB (California Air Resources Board) approved ozone-safe, AHAM tested, UL, and ETL listed all come standard. It is backed by a lifetime warranty covering manufacturer defects and poor workmanship.

Medify Air MA-112 Filtration, Air Performance, And Noise

Medify Air MA-112 outshines the rest of the pack as the top dog. It can clean the room air of up to 2,500 square footage of space in 30 minutes or 2 air changes per hour. Even if you increase the air changes per hour to 4 (every 15 minutes), it can still cover a wide 1,250 square footage of air cleaning space. Ideal for large room size, living room, master bedroom, garage, basement, nursery home, meeting room, or offices. If you're an asthmatic or hypersensitive person allergic to almost anything, the Medify MA-112 air purifier is best suited for you.

The best in its category without a shadow of a doubt. Medify MA-112's clean air delivery rate (CADR) measures how quickly the air purifier removes dust, pollen, and smoke in a fixed environment. Based on AHAM guidelines, the CADR output is at 950 cubic feet per minute, 2-3 times more than its closest rival. We pit it against our trusty Winix 5500-2 for 3 days straight, and Medify MA-112 achieves a healthy air quality index in under 20 minutes every time. No competition.

Why settle for True HEPA when you could go with medical-grade filtration used in hospitals? Medify Air MA-112 air purifier comes with a dual air intake setup. The pre-filters block large particles like dust, hair, fiber, and lint from passing through and prevent the HEPA filter from getting clogged. The dual H13 filter removes 99.9% of microscopic particles as small as 0.1 microns e.g. lead dust, dust mites, mold, pollen, pet dander, bacteria, and virus carrier. The activated carbon filter absorbs common smoke and odor from pets, cooking, and cigarettes. It can also absorb toxic fumes e.g. VOCs, asbestos, formaldehyde, and benzene. An optional ionizer diffuses negative ions to latch nearby pollutants ions in the air. The latched particles will fall from the increased weight allowing the air purifier to pull in and capture the pollutants. If you opt for the newer MA-112-UV variant, an additional UV light uses radiation to sterilize the air for 20 minutes. Ideal for killing germs and viruses before it gets the chance to multiply.

Overall, the proven H13 filtration is super effective but can be costly to replace, especially in the long run. Best suited for those allergic to dust, pets, or mold with breathing troubles. Note that the ionizer will create an insignificant level of ozone byproducts within the CARB Limit. If you are not comfortable using it, switch off the ionizer function to maintain a 100% ozone-free purification.

Medify Air Ma-112 filter

Do not let its size fool you. Medify Air MA-112 can run with absolute silence, and you will not realize its existence. Between 1-4 speeds, the noise output is only between 21 dB (rustling leaves, whispering) and under 50 dB (rainfall). Under unfavorable conditions, Medify MA-112 H13 air purifier noise output can be as loud as a handheld vacuum at 70 decibels. If the generated noise is too distracting, you can tone down the noise by running at a lower speed or selecting Sleep mode to achieve the same result.

Running at 100 volts, the power usage is far from the lowest, given the strong airflow output. Still, it qualifies as an Energy Star rated model (up to 40% energy efficient). To better manage the energy rate, leave it in Auto mode and let the air purifier decide on its own. Medify Air MA-112 will only use higher speed when indoor air quality drops. Otherwise, it will remain at speed one. We average around $3.5 a month on the electric bill with 8-12 hours of operation. Double the cost if you intend to run it 24x7 (highly recommended). Note that your result will vary based on the respective states' charges.

Medify Air MA-112 Pricing, Maintenance, And Drawbacks

Medify MA-112 air purifier 600 price tag (before +-100 discount) is not easy to chew on for regular folks. You're getting all the good stuff for this price, including premium materials, top performance, and high-end H13 air filtration, except for the WiFi remote support. On the flip side, it is a more approachable option when compared with other large segment air purifiers from Blueair, and IQAir, albeit with a different filtration setup.

Another potential obstacle is the close to $400 filter replacement set that you will have to incur every 4 months (3,000 hours). There are no two ways about it. You cannot opt for third-party filters to save costs, as it will void the lifetime warranty. Instead, go with cheaper alternatives like Coway Airmega, Austin Air, Alen, or Rabbit Air which will do a similar job at a much more maintainable cost.

With an expensive tag to begin with, clearly Medify Air MA-112 is not for everyone. For the selected few, it is a fantastic large air purifier with unrivaled CADR performance. Most people that own it have no regrets about the purchase and will even let the expensive filter replacement slide.

5. Medify Air MA-14 Air Purifier

Medify Air MA-14 Air Purifier Review

Medify Air MA-14 Features And Build Quality

Probably the cheapest H13 HEPA air purifier with a proven pedigree. Medify Air MA-14 is a good entry air purifier to improve their home air quality. Comes in at an affordable under 100 price point. At a quick glance, you can hardly tell this clean and compact air purifier apart from other premium models. At only 12.2 inches in height and 8.26 inches in diameter, it is the smallest product in the Medify Air lineup, despite the marginal differences. It will fit nicely on your work desk, TV cabinet, and nightstand when needed to be. The lightweight 5.3 pounds also makes it highly portable for room-to-room air cleaning. For those who travel frequently, you can easily pack it in your luggage or use it in a caravan.

Available in black or white, the front air inlet blends seamlessly into the design without affecting its functionality. The panel can easily be removed to replace the 360 filters. There's a gripping handle at the back that you can hold on to when moving Medify MA-14 around. Overall, build quality is the same as its upper lineup; it will run well for many years to come.

Medify Air MA-14 front control panel is simple to use; even a toddler could understand. You have the fan speed button with four LED indicators, a light button, and an on/ off button. The fan speed button allows you to cycle between the 3 speeds and sleep mode. The dimmable light mode reduces the LED light brightness, which can be particularly useful at night. There's no child lock, timer, AQI, and auto mode here, as it is only available in the higher-end model. A trade-off that you will have to give in for the low selling price.

On the whole, Medify Air MA-14 offers limited features other than its excellent air filtration. However, Keep in mind that it covers only manufacturing defects, excluding the disposable filter. You will need to replace it with a genuine Medify Air filter every 3-4 months to activate the lifetime warranty.

Medify Air MA-14 Filtration, Air Performance, And Noise

As the cheapest model in its series, Medify Air MA-14 has the lowest purifying coverage. It caters to small room sizes, e.g. bedroom, walk-in wardrobe, kitchen, guest room, or office cubicle. At an unrealistic 1 ACH or every 60 minutes, it can clean the air of up to 470 square footage. In a real-life scenario, it can cover up to 200 square footage of room spaces with 2 ACH or every 30 minutes. For an asthmatics person, you can increase the ACH to 4 or every 15 minutes for a lower 117 square footage air cleaning coverage.

CADR mirrors the low airflow output that is nothing out of the ordinary. When tested in a designated room, the CADR is at around 71 cfm for dust, pollen, and smoke. Not great, but it will be sufficient in tight room spaces. Place as close to the polluted sources as possible to get the best out of Medify Air MA-14.

What's Medify Air MA-14 strong suit is the filtration department. It uses purely mechanical filtration that produces no harmful byproducts. When airborne pollutants are drawn inside the filtration, the outer pre-filter will trap particles like dust, hair, pet fur, and lint. At the same time, it also protects the dense True HEPA filter usage life from large particulates. The medical-grade True HEPA filter removes 99.9% of airborne allergens as small as 0.1 microns e.g. mold, pollen, pet dander, bacteria, and viruses. No cutting cost measure here as the filter quality is the same as what you would get from the more expensive Medify Air models. The carbon filter neutralizes smoke and odor from cooking, cigarettes, stinky pets, and VOCs. By keeping it close to you 24x7, Medify Air MA-14 will alleviate your allergy symptoms like cough, sinus, inflammation, and skin redness triggered by bad air.

Another forte of Medify Air MA-14 is the low noise operation. It runs silently at only 21 decibels to a max of 48 decibels, close to quiet conversation. You will barely hear any fan noise, even when placed next to you. Suitable for work, chill, or sleep. Energy usage is equally efficient at only 26 wattages, the lowest in the lineup. Compared with most household appliances like a dehumidifier, air conditioner, oven, and refrigerator. Given the low power output, we recommend leaving it on all the time as it will not burden your energy bill. The electricity cost is around $0.10 per day, $3 a month, or $36 a year, depending on the state's electrical rates.

Medify Air MA-14 Pricing, Maintenance, And Drawbacks

The annual filter replacement is expensive, between $117 to $156. The high filter cost is due to the short 2-4 months/ 2,500 hours filter life. If you can't afford to keep up with the filter maintenance, perhaps Levoit models like Core 300 would suit you better.

On the flip side, Medify Air MA-14 H13 air purifier is a good deal for about $75 after a discount if you only need to use it in a single room. Given its limitation, it still offers good filtration that most budget air purifiers couldn't come close to. However, you can easily step up to MA-15 or MA-25 with better performance and timer for little cash. So study and compare those models and pick the one that suits you best.

Medify Air MA-15 Air Purifier Review

Medify Air MA-15 Features And Build Quality

An affordable and compact air purifier that packs a punch. Medify Air MA-15 is the latest addition to the Medify family, which comes with an advanced H13 HEPA filter. That's right, this tiny air purifier has a higher-grade HEPA filter capable of removing microscopic particles as small as 0.1 microns. Stands at only 9.7 inches in diameter and 15.5 inches in height, you can leave Medify MA-15 on the work desk in the morning and bring it to bed during nighttime. A massive improvement in design and build quality over its predecessor MA-14, the lightweight 6.6 lb makes it easy to carry around by gripping the handle. Surrounding the modern, sleek white/ silver exterior is the bottom-to-top airflow setup with a 360° air inlet and a top air outlet for clean air distribution. The boxy shape allows Medify Air MA-15 to hold two sets of air filters without compromising much on size. Fitting is tight, with zero off-gassings detected despite the plastic build. Expect the same build quality as other premium air cleaner models that cost 2-3 times more. Medify Air MA-15 is ozone-safe, UL listed, AHAM tested, and has a lifetime warranty. You will never have to worry about manufacturing defects/ poor workmanship by committing genuine Medify Air's filter change timeline.

Medify Air MA-15 Air Purifier control panel

Moving to functionality, Medify MA-15 modern exterior is straightforward to use thanks to the familiar yet distinctive buttons. Starting from the left, you have the child safety lock button that locks the control to prevent children from meddling with it. A timer button allows you to set between 1, 2, 4, or 8 hours to shut down the air purifier before you leave for work or hit the sack. A dedicated power-off button turns on/ off the machine, and a fan speed button cycles between the 3 speeds. We are not done yet; there is a dimmable control light button to dim the indicator light. Last but not least, a LED filter replacement indicator that reminds you to change the filter after 2,500 hours or every 3-6 months.

Medify Air MA-15 Filtration, Air Performance, And Noise

Being one of the best affordable air purifiers in the market, Medify MA-15 can cover up to 330 square feet of room space in a mere 30 minutes. However, this is based on the lower air changes per hour (ACH). You must account for a smaller purifying coverage if you intend to max it at 4 ACH or clean air exchange every 15 minutes. You can select between the 3 preset fan speeds based on operational hours. For example, set it to max speed when you are away for work or holiday, and set it to low speed when you need clean air to breathe in peacefully. Being a budget-conscious model, Auto or Sleep mode is unavailable here, so everything has to be done manually.

Medify MA-15 CADR mirrors the airflow output for a small air cleaning device. Clean air delivery rate or CADR measures how fast an air purifier can remove particulates in a room. Under a fixed environment, it can deliver 88 cubic feet per minute (CFM) of clean air free from dust, pollen, and smoke. Not great, but safe to say that Medify MA-15 is ideal for medium room sizes e.g. bedroom, kitchen, dining area, walk-in wardrobe, office, or studio room with moderate air quality.

Despite the low price, Medify Air MA-15 has a dual intake 4-stage HEPA filtration that can capture all types of airborne contaminants. When air is drawn in, the pre-filter block large particles like dust, hair, fibers, and lint from proceeding. It will also prolong the True HEPA filter usage life from being clogged and damaged by dust particulates. The medical-grade H13 TRUE HEPA filter removes 99.9% of allergens as small as 0.1 microns e.g. dust mites, mold spore, pollen, bacteria, and viruses. The carbon filter with carbon pellets absorbs pet odors, cooking smells, cigarette smoke, musty mold, and chemical fumes from cleaning products e.g. VOCs, asbestos, formaldehyde, and benzene. Finally, the anion generator diffuses ions that latch to nearby pollutants in the air. The now merged ions will fall due to heavier weight allowing the filter to capture them.

Overall, the filter quality is decent for its segment, particularly with the inclusion of an H13 HEPA filter. However, we would prefer to use a larger filter than the dual filter setup. Unlike some cheap models that use thin paper sheets, Medify Air MA-15 permanent pre-filter is washable; thus, it will save you a lot in the long run. The optional anion generator is a nice feature to have, and you can disable it at any time. Ideal for those that prefer 100% mechanical, ozone-free filtration.

Medify Air MA-15 Air Purifier

Medify MA-15 has a modest 35 dBA noise output when running at the lowest speed. Not the most silent air purifier on the market, but it will not disturb your workflow or sleep during an operation. In fact, we have been leaving Medify MA-15 by our nightstand for months and barely notice its presence. At the highest speed, the fan noise is at 51 dBA, audible but not overly loud. Use it sparingly when you need a quick air cleaning.

As for power usage, Medify MA-15 is very energy efficient, hovering around 18 watts per hour. You can confidently leave it on 24x7 and will not see any significant increase in your utility bill. With 12 hours of continuous runtime, the estimated electricity cost is around $0.03 per day, $1 a month, or $12 a year. Note the figures vary based on the fan speeds and state electrical rates. For the recommended 24 hours, multiply the numbers by 2, and the cost is still low compared to other home appliances.

Medify Air MA-15 Pricing, Maintenance, And Drawbacks

At such an affordable price point of +-$70 (after discount), we can hardly find any fault with the Medify MA-15 air purifier. It has well-rounded features and a genuine 4-stage filtration, including a medical-grade H13 HEPA filter. The H13 filter itself is worth all the money you paid for.

Competition for Medify Air MA-15 includes the previous Medify MA-14, discontinued MA-18, the more expensive Medify MA-25, and the highly-rated Levoit Core 300. In fact, any compact PureZone or Levoit air purifiers would be an excellent alternative option.

Staying with the filter topic, the $70 to $140 annual filter recurring cost is rather steep, given how cheap the air purifier is selling. Then again, the filter cost is justifiable as you are using a dual filter set ($39) and have to replace it every 2500 hours or 3-4 months. If you can't bear the high filter cost, this is not the right model for you.

Bring to a conclusion, if you want something cheap, dependable, comes with medical-grade HEPA filtration, and doesn't mind the average airflow performance, the budget-friendly Medify Air MA-15 air purifier will fit the bill.

What To Look For In Medify Air Purifiers?

Medify Air comes in all shapes and forms. While it is not hard to pick between the big and small models, this buying guide will go deep to identify the exact air purifiers you actually need. Here are the top features to look into when buying a Medify Air purifier for your home.

  • Dimension and weight - Medify Air covers everything from small/ desktop units to large consoles. Pick a model that can be placed in your room comfortably. Portable is no issue for a smaller air purifiers like MA-14, MA-15, and MA-25 under 8 pounds. Not the case for larger air purifiers like MA-40, MA-50, and MA-112 can weigh as high as 32 pounds.
  • Pricing - Varies from $100 to $600. The bigger and more powerful the unit, the costlier it will be. If the budget permits, go with a more powerful unit.
  • Recurring filter cost - Similar theme to the pricing, Medify Air can range from affordable to expensive to maintain based on the model. Choose a model that you are comfortable paying for the filter replacement annually.
  • Room size - From a small 200 square footage to a high 1,100 square feet, Medify Air covers it all. Measure your room width and depth, then pick a model with the closest suggested room size at 2 ACH. Account for double the purifying coverage if you suffer from asthma or allergies.
  • Clean air delivery rate (CADR) - Bigger model will perform better; it is as simple as that. CADR is a metric by AHAM that measures air purifiers' air cleaning performance. Measured in cubic feet per minute (CFM), the higher the score, the more airborne pollutants will be removed in an hour.
  • Filtration quality - The more, the merrier. If you value filtration strength, pick a larger model with a larger filter surface area. Most Medify Air purifiers come standard with a pre-filter, medical-grade HEPA filter, and an activated carbon filter. A model like MA-50 even comes with a UV light.
  • Noise and power consumption - This one is a no-brainer. If silent operation and energy efficiency are your utmost priority, go with a smaller unit like MA-14, MA-15, or MA-25. In any case, you can't go wrong with any Medify Air models.
  • Features - The filter replacement indicator, child lock, and timer are standard across all models except MA-14. Auto mode is exclusive to MA-112. If you are looking for AQI and WiFi-enabled features, look elsewhere.
  • Lifetime warranty - Standard across all models regardless of the price point.

Is Medify Air Made In The USA?

Yes, Medify Air is a US-based company proudly manufactured in the United States. You can find Medify Air headquarters at 1325 SW 30th Ave Deerfield Beach, FL 33442.

Are Medify Good Air Purifiers?

Medify Air is a good air purifier and is worth every penny spent. Every model uses a HEPA H13 air filter regardless of the price point, a significant advantage over its competitors like GermGuardian, and Honeywell. Medify Air also has excellent air cleaning performance and can cover a large home area. During our test, every model is capable of removing 99% of PM10 and 2.5 airborne particles.

Which Is Better, Levoit Or Medify?

Both are equally good at delivering multiple air exchanges, noise operation, and mechanical filtration. Medify Air has the advantage of a stronger lineup from MA-14 to MA-112. Every model also comes with an H13 HEPA filter; the highest grade of its class. Levoit air purifiers are much cheaper to own and maintain with a lower filter replacement cost. Some model like LV-132 comes with a night light that can be useful when you have children at home.

All Medify Air are H13 HEPA air purifiers that do not produce harmful ozone byproducts to clean the air. It is a certified ozone-free air purifier. For models that come with UV light, you have the option to disable it for 100% mechanical filtration.

How Often Should I change Medify Air Filter?

For optimal performance, Medify Air recommends replacing the air filters every 2500 hours or 3-4 months under normal usage. You can probably stretch it to 6 months, but that would highly depend on the air quality, fan speed, and hours of operation.

Is H13 HEPA Better Than True HEPA?

Yes, medical-grade H13 HEPA filters perform better than True HEPA filters between H10 to H12. The big difference between H13 HEPA and True HEPA is H13 HEPA filter can remove 99.95% of all particles in the air as small as 0.2 microns. The True HEPA filter can only capture 9.97% of airborne particles as small as 0.3 microns. Both will deal with airborne pollutants well, but H13 HEPA filters are commonly used in medical and health facilities due to the greater particulate retention rate.

Does Medify Air Purifier Remove Formaldehyde?

Medify Air purifier removes 99.9% of harmful particles, smoke, and odors, including mold, formaldehyde, VOCs, pollen, pet dander, and smog, down to 0.1 microns in size. Perfect for any home with air quality issues.

How Do you Reset The Medify Air Filter?

After replacing the new genuine Medify filter, press and hold the dimmer button for 3 seconds to reset the filter indicator light. If it does not work, try pressing the ANION button for 3 seconds to reset the unit. Remember to turn off and pull out the power plug before replacing the filters.

How Many Filters Are In Medify Air purifiers?

All Medify Air purifiers come with 3 layers of filtration: a pre-filter, H13/ H14 HEPA filter, and an activated carbon filter for odors.

Is It OK To Leave Medify Air Purifier On All Night?

Yes, it is recommended and safe to leave Medify Air purifiers on all day, all night. If it is not possible, try to run an air purifier for at least 8 hours a day to maintain the air quality and prevent airborne contaminants from returning.
