1. Winix 5300-2 Air Purifier

Winix 5300-2 Air Purifier Review

Winix 5300-2 Features And Build Quality

A worthy replacement to the ever-popular 5300 air purifier. Winix 5300-2 is a good place to start if you are new to the brand. Sharing a dark theme exterior with 5500-2, it has a reasonable price point for a 3-stage filtration. The console's 15 x 23.6 x 8.2 inches dimension is well fitted with classic bottom-to-top air circulation. Stand at a solid 15.4 lb weight, you can effortlessly carry it to different rooms simply by grabbing it on the back handle. Ideal for multi-location use for those that only have a single unit.

Winix 5300-2 angled control panel space is occupied by five operational buttons and a central air quality indicator bar. The controls are nicely labeled and angled for better standpoint visibility. You can cycle between the four fan speeds or enable/ disable auto mode that selects the proper speed based on surrounding air quality. You can also set the run time between 1, 4, 8 hours preset timer or reset the filter indicator after changing to a new filter set. There is also a dedicated PlasmaWave button that will disable the function (on by default). The air quality indicator light will illuminate blue most of the time and only change to yellow or red when the indoor air quality level drops. Sleep mode activates automatically based on ambient light to reduce noise and LED light brightness levels.

Overall, the build quality is sturdy, even though no premium materials are used. No loose parts and off-gassing. We do miss the classic clicky button type more than the touch button here.

Winix 5300-2 control

Winix 5300-2 Filtration, Air Performance, And Noise

Covering a familiar 360 square feet of room space, Winix 5300-2 is excellent at removing household pollutants in the air. The airflow delivery rate is abundant at35.3 cfm to a maximum of 240.1 cfm. Tally with that is the CADR at 232 cfm (dust), 246 cfm (pollen), and 232 cfm (smoke). Safe to say that anything that passes the 200 cfm benchmarks will do well against irritants. Winix 5300-2 air purifier will not disappoint you in airflow performance. Ideal for purifying medium to large rooms, e.g. a bedroom, living room, kitchen, dining room, basement garage, walk-in wardrobe, office, or studio.

Utilizing a 2-in-1 odor-control carbon pre-filter, True-HEPA filter, and PlasmaWave technology, Winix 5300-2 guarantees clean air with no harmful byproducts. The first-stage fine mesh pre-filter traps large airborne particles like dust, hair, and debris. The second stage carbon filter removes smoke and odors from cooking, pets, hazardous fumes e.g. VOCs, asbestos, formaldehyde, benzene. The carbon filter will also protect and prolong the HEPA filter usage life. The True HEPA filter removes fine allergens like dust mites, pet dander, mold spore, mildew, and pollen. Lastly, the optional PlasmaWave Technology releases harmless Hydroxyls (OH) to sanitize bacteria and viruses like Influenza A.

Winix 5300-2 filters

Winix 5300-2 Noise level is on the lower side between 27.8 dB to max 60+ dB when running at turbo speed. With auto/ sleep mode, it is suitable for work, leisure, or nighttime use without much distraction. Energy Star certified Winix 5300-2 is designed for 24x7 operation. Power usage is only at 5 watts at low speed and up to 70+ watts at turbo speed. With a standard 12 operation hours, the average electric cost will be $0.05 per day, $1.6 a month, or 19 dollars a year. Auto mode plays a key role in energy management and reasonable airflow capacity. Just leave it on while you go on with the daily chores

Winix 5300-2 Pricing, Maintenance, And Drawbacks

Winix 5300-2 online price is surprisingly cheaper than 5300, given the all-around improvement. Within its mid-range category, it is an absolute bargain and a "genuine" best bang for the buck air purifier. Filter availability is plentiful, and the annual replacement cost is not overly high, at around $80. The Filter A package comes with 4 carbon sheets and 1 HEPA filter that will last you throughout the year.

The same old, nitty-gritty complaint we have is the carbon sheet's short 3 months lifespan. You will have to replace the carbon filter every 3 months, a big hassle even though it can be done within minutes. It makes more sense to use a better carbon filter that can last throughout the year, like the one in 5500-2. As a lower range model to 5500-2, you lose a physical remote control. If you can spare a few extra dollars, save the trouble and go with the higher variant.

A well-equipped, true HEPA air purifier with a solid track record. Winix 5300-2 is the best budget air purifier to reduce your allergies and asthma symptoms due to bad air quality. It loses out on a few features found in 5500-2, but the overall filtration performance is still the same. If you are happy with the previous 5300 model, this replacement model will suit you well.

Winix 5500-2 Review

Winix 5500-2 Features And Build Quality

Back by popular demand. The beautiful, best-selling Winix 5500-2 air purifier is a significant upgrade over 5500 in almost every department. The most apparent changes are the updated black design with an informative display. Air ventilation placement is a typical console air purifier setup. You have the air inlet at the front/ sides and the air outlet at the top. The well-ventilated exterior stands at a Winix standard 15 x 23.6 x 8.2 inches in dimension with 15.4 lb of weight. Placement is not an issue, even in a limited room area. It fits nicely in most homes without being overly cumbersome. Perfect for placing the air purifier near you without breezing directly in your direction. There is a back handle slot you can grab onto when moving Winix 5500-2 room-to-room purifying.

Focusing on the Winix 5500-2 air purifier's easy-to-use control. The front air quality indicator bar illuminates real-time data depending on the room air quality between blue (good), amber (fair), and red (poor). Next, the adjustable 4 fan speeds cycle between Low, Medium, High, and Turbo. Skip the manual adjustment with an Auto mode that relies on the Smart Sensor to determine the speed needed to remove nearby air pollutants. The sensor-dependent Sleep mode enables autonomously when all lights are out by locking the fan speed to low and reducing LED light brightness. The center dedicated PlasmaWave button activates or deactivates Hydroxyls function. The 1, 4, 8 hours preset timer can be set to shut down the air purifier at a preferred time. A filter indicator light is also standard here to alert users to replace the filter when worn out. Missing in 5300-2, Winix 5500-2 comes bundled with a remote control that allows changes at the comfort of the bed.

Overall the build quality is tight with no visible gap and generous premium finish plastic materials. No off-gassing is detected during our course of ownership.

Winix 5500-2 control

Winix 5500-2 Filtration, Air Performance, And Noise

Winix 5500-2 air purifier slightly improves airflow delivery rate, coverage, and CADR over its predecessor. With an ample airflow delivery rate between 53 cfm to 226 cfm, it is officially rated by AHAM, which covers 360 square feet of air cleaning space. If your home air quality is unhealthy, switch it to Turbo mode and let the air purifier run for 10-20 minutes. AQI will drop swiftly from 100+ to under 10, with more than 99% of airborne particles removed. Ideal for mid to large room sizes such as a bedroom, living room, kitchen, basement, and garage. Aligned with the airflow output, AHAM-certified CADR is at 243 cfm for dust, 246 cfm for pollen, and 232 cfm for smoke.

The dependable PlasmaWave filtration that you can count on. When air is drawn in via the fan motor, Winix 5500-2 pre-filter blocks large particles like dust, lint, pet fur, and hair from passing through. The Advanced Granular Carbon filter (AOC) neutralizes 93% of odors and toxic gases like VOCs, asbestos, formaldehyde, benzene, and tobacco smoke within its proximity. For non-smoke particles, the True HEPA filter trap 99.97% of microscopic particles as small as 0.3 microns like pet dander, mold, mildew, and pollen. PlasmaWave Technology diffuses water vapor and oxygen ion bonded Hydroxyls that break down hydrogen bonds of bacteria and viruses. For those with susceptible lungs, you can disable PlasmaWave technology if you're not comfortable with it.

Winix 5500-2 air purifier

Noise output is silent at around 26.6 dB when running at a lower speed to a white noise 60+ dB territory at turbo speed. Unless the indoor air is deteriorating that requires a turbo boost; you can read, work, watch movies, and sleep peacefully with Winix 5500-2. Being an Energy Star rated model, energy usage is low at only 5 watts minimum to 90 watts max, depending on the fan speed. With a standard 12 hours daily runtime, the electric cost will be around $0.05 per day, $1.6 a month, or 19 dollars a year. The Auto and sleep mode can also help optimize energy efficiency by only using higher speed when the indoor air quality drops. If you have no issue with the previous Winix 5500 noise and power consumption, Winix 5500-2 PlasmaWave air purifier will also serve you well.

Winix 5500-2 Pricing, Maintenance, And Drawbacks

On a good day, Winix 5500-2 air purifiers can be yours for under 150 after applying online discounts. An absolute bargain considering the specification and airflow performance you will get as standard. The filter cost averages around $80 annually for the Filter H set. Not the lowest, but you're getting a True HEPA filter plus carbon filters bundled. Filter availability is good, as the filter set is compatible with a few other Winix models.

There are only a few downsides to Winix 5500-2 that have little impact on the performance. The occasional sensor hiccup will slow to react of gaseous pollutants. Warranty is only 2 years whereas competitor model e.g. Honeywell HPA300 offers up to 5 years. Filter cost is also not the lowest for those that want an absolute budget device.

To conclude, Winix 5500-2 is our best value pick model as the positives clearly outweigh the negatives. Its excellent 4-stage PlasmaWave filtration covers small to large areas well, has tons of features, and is well-priced. To our surprise, Winix 5500-2 air purifier online price is cheaper than the prior model 5500 despite having a newer design and an improved specification. Get this if you want an affordable yet powerful air cleaner.

3. Winix AM90 Air Purifier

Winix AM90 Air Purifier Review

Winix AM90 Features And Build Quality

A smart air purifier for the new era. Winix AM90 is a WiFi-enabled, inexpensive, high-performance air cleaner for its segment. The clean and modern exterior stands at a conventional 15.1 in width, 23.5 in height, and 8.7 in thickness. Not the biggest in its class, so no problem placing it in a tight area. Weight is 16.5 lb consisting of the complete filtration and large front air inlet. Just grab onto the back handle, and you can move it around with ease from room-to-room air purifying. Build quality is solid, as you will expect no less from Winix Brand. A 5-10 years operational lifespan is easily achievable on proper use.

Winix AM90 is blessed with many features that greatly enhance its usability. Powered by the dual Smart Sensor, You'll have the variable 5 speeds, an auto mode that enables higher fan speed when a large concentration of air pollutants is detected, and a sleep mode that activates automatically when all lights are off. The top air quality indicator will also change from Blue (good), Amber (fair), to Red (poor), depending on the room air quality. PlasmaWave technology is optional that can be turned off when not in use. You will also find a standard filter change indicator right next to it.

Winix AM90 is WiFi-enabled, as with most modern Winix models. By downloading Winix Smart App via Google Play or App Store, you can remotely control the air purifier in any part of the world, check filter usage life, access air quality data, and other helpful information. It also supports voice commands from Amazon Alexa devices.

Winix AM90 Filtration, Air Performance, And Noise

With its strong airflow distribution, Winix AM90 room air purifier delivers fresh air in 30 minutes or less within an AHAM Verifide 360 sq. ft of room size. If you are not an asthmatic or have hypersensitive allergies, you can increase the room coverage to 1,740 sq. ft. at 2 air changes per hour or every 30 minutes. Ideal for medium to large spaces like a bedroom, living room, kitchen, garage, basement, small apartment, and nursery home. The clean air delivery rate (CADR) is equally impressive at 233 cfm for dust, 240 cfm for pollen, and 230 cfm for smoke, the same output as 5500-2/ C545/ AM80.

Winix AM90 4-stage air cleaning system is nothing short of amazing. Dirty air is drawn in from the front, where the fine mesh pre-filter will filter large particles like dust, dirt, and hair. For air that manages to pass through, the activated carbon filter primarily absorbs chemicals, smoke, and odors from cooking, pets, diapers, food, and cigarettes via chemical absorption. The True HEPA filter capture 99.999% of allergens in the air as small as 0.003 microns e.g. mold, pollen, mildew, and pet dander. Lastly, PlasmaWave Technology releases Hydroxyls to neutralize bacteria and viruses e.g. Influenza A. The dual polarity ions safely remove hydrogen from air pollutants' molecular structure rendering it harmless.

Noise level is another strong suit of the Winix AM90 air purifier. In sleep mode, it will run silently with a noise level of just 27 dB. Perfect for all-night use when you're trying to get some shut eyes. Power consumption is at the Energy Star rating tier, which will cost you no more than $1.6 monthly. You can run Winix AM90 all night without enduring any impact on your electricity bill.

Winix AM90 Pricing, Maintenance, And Drawbacks

For shy of 200 dollars after discounts, Winix AM90 packs everything you need from a modern-day air purifier. You'll get the familiar AHAM Verifide performance plus WiFi features that can be a game-changer for some like C545. Maintenance-wise, expect an annual fee of 80 dollars for the bundled filter pack.

That said, AM90 does lack a built-in timer and remote control replaced by the Winix SMART app. We are also not a big fan of the lower-grade carbon filter and quarterly filter change, which can be a chore for some. Luckily, the affordable filter replacement cost remains untouched. The WiFi connectivity is not the most intuitive, but we are nitpicking at this point. On the whole, Winix AM90 is a reliable WiFi air purifier that delivers more than most would expect. We highly recommend this model if you're looking for an all-rounder air purifier.

4. Winix AM80 Air Purifier

Winix AM80 Air Purifier Review

Winix AM80 Features And Build Quality

A sign to behold. Winix AM80 HEPA air purifier is the new addition to the lineup below AM90, with identical air cleaning performance at an obtainable price point. The grey exterior and modern design stand out from the boring AP crowd you will typically find. The 15.1 inches width, 23.5 inches height, and 8.7 inches depth framework offer versatility without impairing its filtration performance. The front air inlet draws in much air at one go, while the top air outlet quickly disperses clean air. You can also effortlessly remove the front panel for an easy filter change. Weight is not the lightest at 16.5 lb, but the back handle eases the process of carrying the air purifier. Overall, it is a tried and tested design that one will appreciate its subtleness.

Winix AM80 WiFi air purifier is easy to use with many dedicated buttons. You can adjust the 5 fan speeds, enable or disable Auto/ PlasmaWave. In auto mode, the air purifier will run at a higher speed when an increased concentration level of airborne contaminants is detected. Otherwise, it will remain at the lowest speed. Sleep mode activates when there is no light source. It will set the fan speed to the lowest, disable PlasmaWave, and only revert to the previous setting when there is a light source e.g. opening the room light. Passive features include the top AQI that illuminates Blue when air quality is good, Amber when fair, and Red when air quality is poor. The filter change indicator will alert you to replace the filter once it is dirty or worn out. The only thing missing here is the timer that is only available in AM90 via the Smart app. Winix AM80 air purifier is a high-quality product designed for 24 hours use. It is assured by AHAM Verifide of its performance, UL-certified Standards for Safety, and backed by Winix's 2 years warranty.

Winix AM80 Filtration, Air Performance, And Noise

Enjoy instant clean air with a continuous 1 hour of operation. Winix AM80 air purifier can cover a familiar AHAM Verifide 360 square footage of room space. Toning down to 2 air changes per hour, it can clean the air of up to 1,740 sq. ft. every 30 minutes, 580 sq. ft. every 20 minutes, or 435 sq ft every 15 minutes. Ideal for medium to large room sizes including bedroom, living room, kitchen, basement, offices, and nursery home. In a control testing environment, the Clean air delivery rate is measured at 233 cfm for dust, 240 cfm for pollen, and 230 cfm for smoke. A marginal improvement over its predecessor model and good for everyday use as with most Winix models.

Enjoy clean and fresh air with Winix AM80 air purifier 4-stage advanced PlasmaWave Technology. The first-stage fine mesh pre-filter traps large airborne particles like dust, hair, and lint. It is fully washable, so you will need to clean it from time to time. The second-stage activated carbon sheet absorbs chemicals, smoke, and odors from cooking, pets, diaper, cigarette, VOCs, radon, asbestos, and formaldehyde. It will also prolong the HEPA filter usage life by removing smoke particles. The True HEPA filter capture 99.999% of ultrafine particles in the air as small as 0.003 microns e.g. mold, pollen, pet dander, and germs. Finally, PlasmaWave Technology produces Hydroxyls to remove hydrogen from the molecular structure of allergens, including tiny bacteria and viruses. The discharged dual polarity ions are safe and harmless to our health.

In sleep mode, the Winix AM80 air purifier runs at a whispering 27 dB, and you will barely hear a thing even when placed right next to you. Perfect after a long working day, where you need absolute serenity. As an Energy Star model, energy usage is equally as impressive that will only cost you less than $0.05 per day or $1.6 monthly. For better energy management, leave it in auto mode and let the air purifier decide what speed you need it to work on.

Winix AM80 Pricing, Maintenance, And Drawbacks

Winix AM80 is a well-priced air purifier that brings more value than its price point would suggest. However, its higher range Winix AM90 would be a better pick as it offers WiFi support at a similar or sometimes cheaper price. Sharing the same Filter A 115115 set as 5300-2, AM90, the annual filter replacement cost is around 80 dollars; accessible and perfectly maintainable for everyday folks. Consider AM80 if you want the black color option and have zero intention of utilizing the remote access feature.

Surprisingly, there are a few things in AM80 that we are not a big fan of. As mentioned earlier, pricing is too similar to AM90 or even 5300-2, making it redundant. The lack of remote control and timer can be a big deal for those that rely heavily on both features. The short 3 months carbon filter lifespan requires quarterly change, which can be annoying at times. Still, None of the setbacks are damning to the air purifier's performance. Ignoring the negatives, Winix AM80 air purifier would be an excellent buy if you can snatch a good deal (see price below).

5. Winix C545 Wi-Fi Air Purifier

Winix C545 Air Purifier Review

Winix C545 Wi-Fi Features And Build Quality

Our most well-received Winix reviews of the bunch. Winix C545 is a well-built, high-performance, 4-stage PlasmaWave Air Cleaning machine that ticks all the right boxes. This clean and functional air purifier stands at a boxy 13.7 x 20.5 x 8.4 inches dimension with a large air inlet and a top air outlet. The white exterior gives it a sense of belonging in any modern home without occupying much space. Moving it around for room-to-room purifying is also not cumbersome, thanks to the reasonably light 11.5 lb weight. The supporting handle is well placed and deep enough for an ergonomic grip.

Continue exploring the usability. Winix C545 air purifier dual Smart sensors monitor and maintain room air quality impeccably. You can set the 5 variable fan speeds or leave it on the Auto mode that runs intelligently based on the nearby air contaminants level. Sleep mode disables PlasmaWave, locks the fan speed to the lowest, and dims all indicator lights. It will enable automatically (around 30 seconds) when all lights are out. You can also disable PlasmaWave manually by holding the buttons for more than 3 seconds. The sensor-dependant top AQI will also switch from Blue when air quality is good, Amber when moderate, and Red when air quality is poor. Finally, the compulsory filter change indicator will turn red when it is time to change the filter.

The big upgrade for Winix C545 over C535 is the WiFi-enabled feature. You can now control the air purifier remotely outside e.g. office, shopping, or on the comfort of your couch via the Winix Smart App. From speed management, check filter life, usage log, to monitor indoor/ outdoor air quality in real-time. For added convenience, there is also voice command support from Alexa and tips to help you better operate Winix C545 air purifier.

Winix C545 Filtration, Air Performance, And Noise

Deliver constant clean air that you deserve. Winix C545 can cover an AHAM Verifide 360 square footage of room space at 5 air changes per hour. While it is not the bigger units out there, the air cleaner will fit well in the living hall, master bedroom, kitchen, basement, garage, and even a whole apartment unit. For those with no breathing trouble or asthma, you can drop the air changes per hour to 4 (every 15 minutes) for 435 square feet of coverage or 2 air changes per hour (every 30 minutes) for 1,740 square footage of air cleaning. CADR ratings are the same as other Winix air cleaners. Expect a consistent 243 cfm for dust, 246 cfm for pollen, and 232 cfm for smoke.

If you have seen it once, you have seen it all. Winix C545 air purifier uses the renowned and proven 4-stage advanced PlasmaWave Technology. The permanent mesh pre-filter traps large particles in the air, like dust, hair, and finer lint, from passing through. It is the only filter you can wash to extend the usage life. The activated carbon filter absorbs smoke and odors from cooking, pets, diapers, and cleaning products like chemicals e.g. VOCs, radon, asbestos, and formaldehyde. The carbon filter also protects the HEPA filter from being damaged by smoke particles. The True HEPA filter captures PM2.5 particles in the air, like mold, mildew, pollen, dust mites, and pet dander. Lastly, PlasmaWave Technology safely disperses Hydroxyls to neutralize bacteria and viruses. To maintain performance and longevity, ensure the filter change is performed according to the schedule.

Winix C545 is also perfect for bedtime use with its silent 27 dB operation, similar to whispering. Even without relying on sleep mode, you can keep the noise level down by running at the lowest speed during work or leisure time. The same story goes with power efficiency. Energy Star certified Winix C545 uses between 5 to 70 watts of electricity depending on the operating speed. It will cost you less than 20 dollars of electricity bill annually when you leave it on 24x7.

Winix C545 Pricing, Maintenance, And Drawbacks

On paper, the Winix C545 air purifier is the perfect model for ordinary folks like you and me. It has an autonomous mode, strong airflow, dual sensors, and is WiFi-enabled for less than 200 dollars. For context, AM80 is in the same price bracket without WiFi support. The Filter cost also favors Winix C545 at only 60 dollars annually for a HEPA filter and a 4 set of carbon filters. Filter set A is also inter-swappable with other Winix models; you can freely swap between your other compatible Winix air cleaners to save costs.

Following the same theme as AM80, the minor drawback of the Winix C545 are the lack of a built-in timer (replaced with the app). We prefer a quick set straight from the control panel, but that's how the way it is. The hassle of quarterly filter changes doesn't help the usability either. Setting up the WiFi pairing can be tricky, especially for a new beginner. Thankfully is a one-off thing, where you can set and forget.

If you are truly interested in getting one, be quick to do so, as availability is scarce. Most stores do not carry the model anymore. You will be better off with a Winix AM90 that offers identical specifications and performance at around the same cost.

6. Winix A231 Air Purifier

Winix A231 Tower Air Purifier Review

Winix A231 Features And Build Quality

Winix doesn't do small air purifiers...... until now. Introducing the latest compact model, the conical-shaped Winix A231 tower air purifier. This dual-color tone, 9.5 inches diameter and 14.6 inches height compact air cleaning device is well made with no signs of leakage, cutting corners despite the compressed size. Winix A231 will fit nicely on the working table, kitchen tabletop, bedside, and TV cabinet without occupying much space. The portable form factor also makes it a bliss when you need to carry the air cleaner into the room at night.

Staying with the design. Winix A231 air purifier simple yet functional 360° air ventilation is supported by an easy-to-use control panel. The top air quality indicator shows Blue when AQ is good, Amber when fair, and Red when AQ is poor. You can cycle between the four fan speeds or choose Auto mode, which uses a higher speed when there is an increased density of contaminants in the air. Sleep mode only works manually by disabling PlasmaWave, indicator light, and locking the fan speed to the lowest. You can also disable PlasmaWave by holding the buttons for more than 3 seconds. Last but not least, the filter change indicator turns red when the filter is dirty or requires replacing.

Winix A231 Filtration, Air Performance, And Noise

With 360-degree ventilation, Winix A231 can pull in airborne particles at every room corner of the room. It can reach up to 230 square footage of room size at AHAM Verifide 5 air changes per hour. If you need to cater to a bigger room, drop the air changes to 2 for an extended 555 square footage. The clean air delivery rate (CADR) does take a dip from the rest of the lineup at 149 cfm for dust, 154 cfm for pollen, and 147 cfm for smoke. Not the best, but that's the compromisation of a smaller body. Winix A231 air purifier is suited for small bedrooms, offices, playrooms, kitchens, studio, and apartments with limited living areas.

Despite the compact size, Winix A231 air purifier uses the same 4-stage PlasmaWave filtration as the rest of the pack. Airborne pollutants will first be captured by the mesh pre-filter that blocks dust and other large particles from passing through. The activated carbon filter neutralizes tobacco smoke, rotten food smell, VOCs, pet odors, and toxic fumes such as radon, asbestos, and formaldehyde. The True HEPA filter capture 99.97% of allergens as small as 0.3 microns like mold spore, pollen, dust mite, and pet dander. Lastly, PlasmaWave diffuses natural dual polarity ions Hydroxyls to deactivate bacteria and viruses. The technology is 100% ozone safe, certified, and approved by California Air Resources Board (CARB).

Winix A231 is the most silent air purifier listed here, although you can hardly tell the differences in real life. Running under 25 decibels at the lowest speed, you will not hear any noise when the air cleaner is placed right next to you during work, relaxation, or snoozing time (with Sleep mode). A crucial consideration for those who always have their air purifier by their side. As for energy efficiency, the Energy Star certified Winix A231 power is explicitly designed for all-day operations. Expect an efficient electric cost of a mere 1-2 dollars monthly with 12 hours of daily operation.

Winix A231 Pricing, Maintenance, And Drawbacks

Before we touch on the pricing, let us define what Winix A231 is and what it isn't. It is a proven, compact, 4-stage PlasmaWave air purifier that will improve your indoor air quality. However, it is not a direct replacement for your console air purifier. You will have to settle for weaker airflow output, smaller filters, no timer, and smart features. The manual sleep mode activation can be a deal-breaker for those used to how Winix air purifier works.

Switching to a more positive note. There are 2 variants of Winix's most compact air purifiers. Both Winix A231 and A230 can be yours for around 70 to 100 dollars, depending on sales and promotion. Not only it is the cheapest Winix air purifier to date, it is also the smallest and easiest to maintain. Expect a low 50 dollars annual filter replacement with the whole PlasmaWave treatment and 2 years manufacturer warranty. Without a shadow of a doubt, Winix A231 is the perfect starter air purifier for all.

Winix C535 Air Purifier

winix c535 air cleaner

Another popular Winix model at the end of its cycle. Winix C535 is the longest-standing air purifier you can still get your hands on. The white 15.1 x 23.5 x 8.7 inches dimension and 15.4 pounds weight is the golden standard for a console air cleaner. It has wide air ventilation, takes up little space, and is lightweight enough to carry with one hand. While we wish the top air quality is located at the front for a more practical viewing angle, there is less light glaring for night use.

Winix C535 controls are straightforward to use with zero learning curve. You have the standard 5 speeds plus the must-have Auto mode powered by the Smart sensors (VOC/ odor/ light). The auto mode also works in conjunction with the auto-sleep mode; both activate automatically without having you lift a finger. Other standard controls include PlasmaWave on/ off function and reset filter change indicator after you have replaced it with a brand new filter. The built-in 1, 4, 8 hours timer is a convenience feature missing in the latest Winix lineup. Lastly, a 2 years warranty is included unless your unit is a refurbished model.

Catered for medium to large room sizes, Winix C535 is suitable for living rooms, bedrooms, kitchens, basements, and nursery homes. The official AHAM Verifide stands at 360 square footage, measured at high air changes per hour. Again, depending on the room’s air quality and health, you can reduce the clean air distribution frequency for wider air-purifying coverage. CADR is measured at 243 cfm (dust), 246 cfm (pollen), and 232 cfm (smoke) without adding PlasmaWave into the equation. Winix C535 air purifier also runs whisper-quiet with the help of Sleep mode. It is enabled automatically every time you turn off the light for a good night’s sleep. Power usage is also on the lower tier, where you will not feel a pinch on your utility bill.

Winix C535 uses excellent PlasmaWave Technology that will not let you down. The washable mesh pre-filter captures large PM10 particles in the air, like dust and hair. The activated carbon filter absorbs household cigarette smoke, musty smell, and toxic fumes. The carbon filter also protects the HEPA filter from being damaged by smoke. The True HEPA filter removes 99.999% of microscopic particles in the air, like mold, pollen, and pet dander. PlasmaWave Technology releases Hydroxyls that destroy germs, bacteria, and viruses by removing hydrogen from the molecular bond. Unlike an ionizer, PlasmaWave disperses both negative and positive ions that are safe to inhale with no harmful side effects.

Winix C535 air purifier is affordable as a brand new unit, let alone the refurbished models. You’re getting the full package similar to other premium variants bar the WiFi feature. The maintenance cost is also on par with the rest of the Winix air purifiers lineup. However, it has limited availability, considering the age of the product. Other brand new models like C545, AM80, and AM90 offer identical performance and price. Since they share the same filter replacement set, swapping the filters between them is no issue.

Winix HR900 Air Purifier

Winix HR900 Air Purifier Review

Winix HR900 is a pet-approved, multi-stage filtration HEPA air purifier with an Ultimate Pet filter (more on this later). While the console’s 16.3 x 23.6 x 9.6 inches dimension does not reflect its pet focus selling point, it is highly functional for any type of home. The exterior features a big air inlet and top air outlet that allow quick clean air distribution. Transporting the air purifier for room-to-room purifying is also pretty seamless with its 18.7 lb weight and back-grabbing handle. With its solid fitting and reliable track record, Winix HR900 will have no problem lasting for ages.

Oh, the sweet, tactile feel. Winix HR900 comes with 6 physical buttons for quick access and easy operation. You can set the speed between Sleep, Low, Medium, High, and Turbo. Alternatively, choose Auto mode, which allows the air purifier to manage and adjust the fan speed based on room air quality. The 1, 4, 8 hours timer can be set to shut down the air purifier to conserve energy. The dedicated PlasmaWave button activates/ deactivates the feature. The filter reset button will disable the filter light when you hold the button for 5 seconds. Other practical features include a child lock that prevents children from meddling with the controls and a Smart Sensor dependant AQI that can be disabled when not needed.

A great improvement over the predecessor WAC9500, the Winix HR900 air purifier can cover a medium room size of up to 300 square footage. Ideal for a small living room, bedroom, kitchen, playroom, and walk-in wardrobe. The strong airflow delivery rate also pushes the CADR up to 200 cfm for dust, 220 cfm for pollen CADR, and 194 cfm for Smoke CADR. Decent, but if you need a higher output CADR, consider Winix AM80 or AM90 instead. The noise level and power consumption are on par with the other Winix air purifiers. Anticipate a silent under 30 decibels operation with Energy Start certified efficiency. Again, sleep mode and auto mode are available to help further optimize performance.

Touted the ultimate 5-stage filtration pet air purifier. The initial pre-filter removes PM10 traps like dust mites, hair, lint and prevents them from clogging the other filters. The filter is washable, so that you can reuse it repeatedly. Through chemical absorption, the advanced granular carbon filter (AOC) removes smoke particles and pet odors well while protecting the HEPA life from getting clogged. The True HEPA filter focus on removing harmful, ultrafine particles known to trigger many allergy reactions. Unique in Winix HR900, the ultimate pet filter captures pet dander and allergens commonly found in your cat or dog. PlasmaWave safely breaks apart hydrogen and chemical vapors at a molecular level before releasing clean air.

Do not be fooled by the Winix HR900 air purifier’s high retail price, as you can easily find one with a massive discount at around 215 dollars. While there are cheaper Winix air purifiers here, this is the only 5-stage filtration pet machine offering an extra layer of protection against germs. Filter replacement cost is also slightly higher than expected for the additional pet filter. In short, if you have cats, dogs, or any indoor pets, you can’t go wrong with Winix HR900.

What To Look For In Winix Air Purifiers?

Every Winix air purifier can help improve your indoor air quality, and that's an undeniable fact. However, identifying the right Winix air purifier for you can be challenging, as every model brings a lot to the table. Here are the top features you need to look into to guide you on the buying journey.

  • Dimension and design - Pick a model you are comfortable with day in and day out. Most Winix models are regular-size console air purifiers, with the exception of a few tabletop models. You will have no issue finding space to place the device.
  • Weight and portability - A typical Winix model weighs between 11-18.8 pounds which is reasonable for its category. Even without the built-in caster, you can easily move it around by grabbing the integrated handle. That said, none of the Winix air purifiers are travel-friendly. If that is what you're looking for, look elsewhere.
  • Pricing - Winix air purifiers offer exceptional value that is hard to beat. Most models are priced between 100-200 dollars price bracket for a Korean-made air purifier. Compact models like Winix A230/ A231 can be yours for less than 100 dollars after applying online discounts. You can get better deals during seasonal or Black Friday sales.
  • Recurring filter cost - Winix filters are inexpensive but far from cheap. Depending on models and home air quality, Anticipate a filter replacement set to cost between 50-120 dollars yearly. The smaller and less filter there is, the cheaper the maintenance will be.
  • Room size - The size of the air purifier will determine its air-cleaning coverage area. All Winix air purifiers are AHAM Verifide, covering medium to large room sizes at 5 air changes per hour. Think where you intend to place the air purifier and refer to the manufacturer's recommended room size for comparison.
  • Clean air delivery rate (CADR) - The higher the ratings, the quicker airborne contaminants will be removed. CADR is a numerical metric developed by AHAM to measure the air cleaning performance of residential air purifiers. Measured in cubic feet per minute (CFM), most full-sized Winix air cleaners have at least 200+ CADR.
  • Multi-stage filtration - Never settle for less. All Winix air purifiers come with at least 4-stage filtration, including PlasmaWave technology and permanent pre-filter. Older models use a True HEPA filter with 99.97%/ 0.3 micrometers removal efficiency on particles. Newer models use a superior HEPA filter that captures 99.999% of particles as small as 0.003 micrometers. The same goes for the carbon filter. Some models use an inferior carbon sheet over a standalone activated carbon filter with better chemical adsorption.
  • PlasmaWave technology - All Winix air purifiers come with the trademark PlasmaWave technology. A standout feature from other brands that you can't miss.
  • Noise and power consumption - Not a big concern, regardless of which models you go with. Winix air purifiers can be silent and efficient with the dependable Smart Sensor.
  • Supporting features - Winix air purifiers are very well-equipped regardless of price. Standard features include Auto/ Sleep mode, Smart Sensor (single/ dual), air quality monitor, digital display, and filter change indicator. Optional features include remote control, timer, child lock, and WiFi-enabled.
  • Warranty and after-service - Most models come with a manufacturer 2 years warranty, while older models may offer up to 5 years. Discontinued or certified refurbished models e.g. FresHome series, come with a standard 1-year warranty. For claims and warranty, Winix dedicated U.S. customer support (phone/ email) that swiftly troubleshoots any issue you are facing.

Is Winix Air Purifier Any Good?

Winix is a good brand that produces some of the best value air purifiers out there. It is exceptionally good at cleaning the air in your home with a 99.999% particle removal efficiency (independently tested) under 30 minutes. Winix air purifiers are also reliable and durable for everyday use. Powered by the innovative PlasmaWave technology, newer models all come with at least 200+ cfm CADR ratings certified by AHAM verified and CARB. Best of all, most Winix air purifiers are affordable and typically cost below 250 dollars.

How Does Winix Purifier Work?

Winix air purifiers do work and are very effective in cleaning the air with HEPA-based PlasmaWave technology. Newer models all come with at least 200+ cfm AHAM-certified CADR ratings that swiftly improve air quality by removing dust, mold, pollen, germs, smoke, and other fine particles in the air. As long as you use the Winix air purifier indoors and within the recommended room size coverage, it will perform flawlessly.

How Long Do Winix And Filters Last?

How Long Do Winix Filters Last? How Often Do I Need To Change? Winix's HEPA filter will last around 1 year (12 months) before it requires replacing. The activated carbon filter will last 3 months to 1 year, depending on the material type, indoor air quality, and the types of airborne contaminants. Odor control carbon pre-filter requires a change every 3 months. By default, a brand-new Winix model comes bundled with a filter set that will last throughout the year. Some Winix HEPA and AOC carbon filters are washable up to 6 times; we do not recommend doing so as you might accidentally damage the filter. The washable pre-filter is reusable and does not require replacing unless damaged. PlasmaWave technology is filterless and evergreen, so it doesn't need replacing.

Note that external factors could impact the Winix filter's life. The more unhealthy indoor air quality, the more impurities there is in the air, and the shorter the filter life will be. Winix air purifiers can last for a lifetime as long as the filter is replaced on time and runs with a local voltage electricity outlet.

How Does Winix Measure Air Quality?

Winix air purifiers measure air quality with Smart sensors that detect airborne particles, smoke, and VOCs in the room. The LED air quality indicator calibrates and displays the level of indoor air pollutants based on the collected data. You can manually set the desired speed or enable the Auto mode that automatically adjusts the fan speed in real-time to deal with surrounding airborne contaminants. When the room is pitch black, Sleep mode will activate automatically by locking the fan speed to the lowest, disabling PlasmaWave, and turning off all indicator lights.

How Quiet Is The Winix Air Purifier?

Winix air purifiers are whisper quiet, generating noise between 25 - 60+ dB depending on the fan speed. With Sleep mode, it is suitable for work and nighttime use with no noise distraction. The most silent air purifier currently available is Winix A230/ A231.

What does Orange/ Yellow/ Red Blue light on Winix mean?

Winix air purifiers use color-coded LED lights to indicate the current indoor air quality. Blue = good air quality, amber = average air quality, and red = poor air quality. The color indicator will shift from time to time when the sensor detects a degree of air pollution.

Does Winix Work Without PlasmaWave? How Do I Turn It Off?

Winix air purifiers work without PlasmaWave; you can turn it off anytime. While it is not necessary to keep PlasmaWave on, it is an effective air purification that can help remove airborne pollutants. We highly recommend you leave it during purification. You can turn off PlasmasWave by holding the power button for 3 seconds or until the Plasmawave indicator green light is off. Applicable to most Winix air purifiers.
