How Do We Measure?
hOmeLabs Purely awesome air purifier is a highly sought model despite being relatively new. At around 80 dollars after an online rebate, you'll get plenty of goodies including the game-changer HEPA H13 filter. A higher grade filter that can improve indoor air quality within a short few hours of runtime.
Housing the 3-in-1 filtration is the compressed body at 12.8 inches in height and 7.9 inches in diameter. This compactly engineered air purifier will fit nicely in most homes especially studio or small apartments with limited space. Adding the light 5.3 lb weight means moving hOmeLabs Purely HME020248N around would not be an issue. The clean white design is achievable by tucking the air inlet at the bottom and the air outlet surrounding the top controls. The entire layout makes sense as more pollutants can be drawn in even at the bottom while clean air can be distributed further at the top. Overall the quality is decent with no off-gassing detected during our test.
Lets look into hOmeLabs Air Purifier HME020248N specification:
- Filtration Type - 3-stage
- Air Filtration - Pre-filter, H13 True HEPA filter, Activated Carbon filter
- Noise Level - ≤50 dB
- Warranty - 1 - 2 years
- Coverage Area - 78 sq. ft.
hOmeLabs Purely HME020248N air cleaner is powered by conventional and proven 3-stage filtration. With dirty air drawn in, the pre-filter will trap dust, hair, and other larger particles from damaging the HEPA filter. The higher-grade H13 HEPA filter will focus on removing 99.97% of finer particles in the air like pet dander, mold spore, pollen, and germs. The last stage activated carbon filter will absorb light smoke and odor from cooking, pet, spoil food, and smelly toilet. At full speed, hOmeLabs HME020248N is ideal for the kitchen, home office, playroom, and bedroom as long as it is within small-sized spaces.
Features wise, hOmeLabs Purely HME020248N does not disappoint in spite of its low price. You have the standard 3 fan speeds that help you keep a balance between performance and noise output. Filter reset indicator reminding you to replace the filter after 2100 hours of usage on low/ medium speed. The baby nursery room favorite child lock function prevents children from fiddling with the settings. There is even a nightlight with a dimmable brightness option. Leave it on all-night for extra comfort and safety without being disturbed by the glaring light.
Moving to speed and sound, hOmeLabs HME020248N ≤50 dB noise is whisper quiet at the lowest speed but there will be white noise at max speed. Absolutely usable at night compared with other bigger air purifiers with higher output. As for power consumption, the standard 120 volts/ 60 Hz power output is very energy efficient for continuous operation. You can turn off the nightlight during day time for a more eco-friendly approach.
So what's not so great about hOmeLabs HME020248N? To start, the 48.3 cfm CADR and 80 square feet room coverage are not impressive. You will need to constantly run it at high speed to cover more spaces. Due to the lack of sensors, there is no special cleaning feature like Auto or sleep mode. Even though changing the all-in-one filter is easy, the short 87 days or 3 months filter lifespan can be a hassle as well. The frequent change also contributes to a higher filter replacement cost. Regardless of all, hOmeLabs HME020248N is a great sleeping companion that can help you breathe and sleep easily as long as it is placed close to you.
In short: A portable and price-friendly HEPA H13 air purifier for less than 100. The only catch is the airflow delivery rate is very limited.
- Compact HEPA air purifier for less than $100.
- Medical-grade H13 HEPA filter.
- Activated carbon filter.
- Child lock.
- Adjustable night light.
- Restricted 80 sq. ft. coverage.
- Short filter lifespan (3 months).
- No autonomous mode.
The only Aromatherapy air purifier with HEPA filter for around 80 bucks (after rebate). Elechomes EPI081 is a great air purifier for home for many reasons. It is affordable, reliable, pet-friendly, and comes with an upgraded 4-stage purification system that can cultivate healthier and cleaner air.
At a compact travel size of 9.3 inches in height and 6.3 inches in diameter, practicality and performance are still intact with Elechomes EPI081. The white modern design is surrounding by a 360° air circulation that can capture airborne pollutants at every angle. The airflow outlet is placed at the top for extensive distribution and quick filter change. Right at the center, there is an essential oil slot to support the built-in aromatherapy function. Insert your favorite essential oil pads to help you destress, relax, clear sinuses, and promote better sleep.
Continue with the exterior, the prominent control panel is located at the front with multiple blue LED indicators. Through the smart panel, you can set a specific time to turn off the air purifier after running for 1, 2, 4, or 8 hours. You can also manually select the 3 fan speeds or Sleep mode where Elechomes EPI081 will run at the lowest speed with dimmed light. Alternatively, leave it in Auto mode via the dust sensor and the machine will automatically set the right speed based on the room air quality. Filter change indicator is also here to remind you to replace the composite filter after 3,000 of use. Not bad for a below 100 budget air purifier with limited capacity.
Touching on Elechomes EPI081 specification:
- Filtration Type - 4-stage
- Air Filtration - Fine preliminary filter, Antibacterial filter, Activated carbon filter, True H13 HEPA filter
- Noise Level - 30 dB
- Warranty - 18 months
- Coverage Area - 215 sq. ft.
How Elechomes EPI081 manages to fit in a quadruple filtration is beyond us. First, you have the protector pre-filter that captures dust, pet hair, debris in the air while extending the HEPA filter usage life. Next, the antibacterial filter will prevent trapped bacteria and viruses from multiplying. The HEPA H13 filter will target 99.97% of PM2.5 particles like mold, spore, dust mites to capture down to 0.1 microns (40 times smaller than pet hairs). The activated carbon filter will remove irritating smoke and odors from pets, mold, cooking, rotten food, and cigarette. Without ionizer and UV-light technology, Elechomes EPI081 is 100% ozone-free with zero byproduct produced. By leaving the air purifier running all day, you will experience fewer allergies like sneezing, coughing, skin rash, headache due to bad air.
At full speed, Elechomes EPI081 can clean up to 215 square feet in an hour. For asthmatic sufferers or hypersensitive people, you can double the cleaning effort at a smaller 125 square feet of space. The air purifier performs best in the bedroom, dormitory, kitchen, small office, and baby room without being overwhelming.
Being a compact air cleaner, Elechomes EPI081 upgraded noise reduction technology a very silent at only 30 dB (sleep mode). At full speed, the white noise level is still tolerable for restful sleep. For power consumption, it is identical to most air cleaners here with or without auto mode activation. Even running for an entire month, expect an insignificant cost added to your electricity bill.
With so many positives, there are some negatives with Elechomes EPI081 air purifier that you should not overlook. First, the AHAM verified clean air delivery rate is at a low 47 cfm. That means it is not super effective against smoke and chemical fumes like VOCs, ammonia, formaldehyde, and benzene. The short 6 months or 3000 hours composite filter lifespan means you will have to replace it more regularly to ensure maximum efficiency. In long-run, the filter replacement cost will stack up quicker than most models here. Bypassing both setbacks, Elechomes EPI081 is no doubt an excellent air purifier with plenty to offer.
In short: Compact 4-stage air purifier with HEPA H13 filter for less than 80. Very well featured too but you do have to settle with a small purifying coverage.
- Cost slightly above $50 after discount.
- Compact travel size with 360° circulation.
- Antibacterial filter.
- True HEPA H13 filter.
- Activated carbon filter.
- Auto mode, sleep mode, timer, essential oil.
- Not effective against chemical fumes.
- Only 47 cfm CADR.
- Short replacement composite filter lifespan.
Continue with this very competitive entry-level segment, PureZone 3-in-1 is one of the best value air purifiers with 2000+ Amazon reviews. It has built its own fan base and rightly calls for a spot here. With a selling price tag of slightly above 100 after sales, it can greatly transform your indoor air making it more comfortable to breathe. A phenomenon result considering the number of emerging air cleaner brands that fail to do so.
At a mere 6.9 x 12.1 x 10.8 in dimension and 8.4 lb weight, PureZone 3-in-1 is on the smallest side for a console air purifier. The modern exterior added a touch of elegance to your home without sacrificing build quality and functionality. The air inlet is nicely tucked behind the front panel with an air outlet at the top surrounding the easy to use touch-button control. Portability is another strong suit for PureZone 3-in-1 if you intend to carry it for room to room purification.
Here is the run-through of PureZone 3-in-1 specification:
- Filtration Type - 4-stage
- Air Filtration - Pre-filter, HEPA filter, Activated Carbon Filter, UV-C Light
- Noise Level - 30 - 50 dB
- Warranty - 5 years
- 200 sq. ft. purifying coverage - For small to medium room size
What makes PureZone 3-in-1 great is the Holy Grail air filtration. The stage 1 pre-filter traps initial dust, hair, dust mites, and large particles while protecting the inner filter. The stage 2 activated carbon filter absorbs noxious chemicals like formaldehyde, benzene, and odors from pets, diapers, cooking, cigarettes. The stage 3 True HEPA filter removes 99.97% of dust mites, mold, pollen, pet dander, fungi, and other allergens in the air. The stage 4 UV-C light sanitizes bacteria and viruses before releasing clean, fresh air back to your home.
PureZone 3-in-1 does not use an economical HEPA-type filter like most small and affordable air purifiers. At max speed, the mid-range purifying radius that covers up to 200 square feet of room space. Excellent for bedroom, office, kitchen, garage, dining room, and baby room. Removing large contaminants to microscopic allergens would be a piece of cake.
PureZone 3-in-1 is not shy about features too despite the low price tag. You have 2, 4, 8 hours timer that can be set to turn off the air purifier when the time is up. Filter reset button that is used after you changed the filter. Standard 3 speed and sleep mode for silent purification during sleep. To boost the energy-efficiency, you can even turn off the optional UV-C mode to save energy costs. Finally, PureZone 3-in-1 is backed by a hassle-free 5 years warranty that mitigates any fears of the air purifier breaking down.
Few things you should take note of before purchasing one. CADR is not spectacular at 80 cfm level even though purifying coverage is decent. The all-in-one filters have a relatively short 6 months lifespan so you will have to change it more regularly. The lack of autonomous features is expected given the low price. Lastly, the brand does not have another high-range model to upgrade to. If you are planning to move up from the stable line in the near future, you're out of luck. Other than that, PureZone 3-in-1 is a worthy, entry-level air purifier for those that are new to the scene.
In short: One of the best value HEPA air purifiers with UV-C light technology. Great for people with breathing issues due to allergies or asthma.
- Affordable 3-in-1 air purifier (+- 100 after discount).
- Wide room coverage for a small air purifier.
- Genuine HEPA filter and activated carbon Filter.
- UV-C Light.
- Timer and sleep mode.
- 5 years warranty.
- Unimpressive CADR.
- No autonomous features.
- Short 6 months filter lifespan.
The smallest and most affordable HEPA air purifier under $100 (or 50+ after discount). GermGuardian AC4100 might not be the new kid on the block, it still manages to squeeze in a respectable 3-in-1 filtration with UV light. The speaker alike exterior is pleasing to the eyes with a front air inlet. The compact 6.5 x 11 x 7.5 in body and 4.85 lb weight means you gain the portability perk where you can easily pack it for travel. AC4100 can be run in either vertical or horizontal position without impeding the airflow. You can be placed at any location including the top shelf, bedside table, or desk with ease.
Operational wise, GermGuardian AC4100 is very easy to use with a dial knob that controls the 3 fan speed and a UV-C light control button. However, there are zero supportive features to enhance the overall usability. It is the most basic form of air cleaner you can get.
Given its restricted airflow circulation, GermGuardian AC4100 is almost noiseless apart from the mild white noise running in the background. Even running at the highest speed, it will not disturb your sleep. Great for night use but sadly there is no sleep mode to help you manage the noise. As for upkeep, the power usage is low so running it all day, every day is doable without the extravagant cost.
Let's look at GermGuardian AC4100 air purifier filtration bundled:
- Filtration Type - 4-stage
- Air Filtration - Charcoal Pre-filter, HEPA-type filter, UV-C Light, TiO 2
- Noise Level - Silent
- Warranty - 1 year
- Coverage Area - 78 sq. ft.
HEPA filter, charcoal + PCO filter, and UV-C technology are standard in this tiny air cleaner. First off, you have the dual function charcoal pre-filter that reduce household dust, hair, cigarette smoke, and cooking odor while extending the life of the HEPA filter. Next, the main HEPA-filter will get rid of 99% of illness-causing allergens in the air as small as 2 microns. For finer microorganisms that cannot be capture by the filter, you have the UV-C light that specializes in killing bacteria and viruses like Influenza, staph, rhinovirus. Complement nicely with Titanium Dioxide to reduce volatile organic compounds in the room.
The maximum of 78 sq. ft. coverage is very restricted for close-range purifying but does help alleviate allergic reactions linked with bad air. AHAM verified CADR is at 56 cfm for dust, 76 cfm for pollen, and 50 cfm for smoke. Not bad for a small air purifier that is supposed to cut costs at every corner.
Replacing the filter set is easy but you will have to do it every 6 months. The longer-lasting 2 Watt UV bulb requires replacing every 10-12 months which is music to our ears. You can even turn the UV light off to extend the usage lifespan. Unlike most air purifiers that offer digital filter change indicator, GermGuardian AC4100 uses a manual filter reminder date wheel. A very old-fashion approach that most would not appreciate.
For the low price you paid, GermGuardian AC4100 can only do so much. The small body means you have to compromise on a few things, mainly the filter size and performance. The bundled HEPA-type filter is not the same as a True HEPA filter. It also uses an inferior charcoal pre-filter instead of a dedicated carbon filter. The airflow delivery rate is also limited to small rooms up to 78 square feet. You can bypass all the drawbacks we mentioned with other premium models in this list.
In short: Cheapest 4-stage HEPA air purifier that costs even less than some air cleaners' filter. For slightly above 50 dollars, it is the ideal model if you don't mind the small purifying area.
- Very affordable UV HEPA air cleaner.
- Portable size that runs vertically/ horizontally.
- UV-C light kills bacteria and viruses.
- Quiet operation at all speed.
- Weak airflow distribution.
- 2-in-1 charcoal pre-filter.
- Inferior HEPA-type filter.
- Manual filter reminder date wheel.

- Filtration Type - 3-stage
- Air Filtration - Pre-filter, HEPA-grade filter, Carbon zeolite filters
- Noise Level - Silent
- Warranty - 1 year
- Coverage Area - 140 sq. ft.

Protecting the HEPA filter is the permanent pre-filter that traps pet hair, dust, and other large contaminants. Lastly, the two optional carbon zeolite filters will reduce pesky pet odors and smoke indoor.

Setting it to max speed, the triple filtration will effortlessly remove airborne irritants within its 140 square feet purifying range. Ideal for bedrooms, nurseries, hallway, small offices, and dens.
The biggest advantage of using a permanent HEPA filter is you can reuse the filter for many years to come. Simply remove the front panel by pressing down the opening tab and take out the HEPA filter for vacuuming. That way, you can extend the HEPA-type filter span and save money for something else. As for the two carbon zeolite odor-eliminating filters, you should replace them every 3 months or when necessary. To make sure you replace the filter on time, there is a timestrip cartridge that will indicate when it is time for a change.
Another hallmark of Hamilton Beach TrueAir Compact Pet is the ultra-quiet motor and fan. Running at the WhisperClean, you will barely hear any noise as if the air purifier is not operational. At a medium or QuickClean speed, there is a slight humming fan sound that can even be soothing for some. Energy usage is low given the subdue airflow delivery rate. Adding the permanent reusable HEPA filter, there is hardly any recurring fees with Hamilton Beach TrueAir.
Let's get the usual cons out of the way for Hamilton Beach TrueAir Compact Pet air purifier. For this budget category, anticipate limited coverage and weak HEPA-type filtration when compared with a True HEPA filter. Great for pet owners but so so for allergy sufferers that need faster air cleaning. Supporting features is also non-existence. Besides the filter change indicator, there is no auto mode, sleep mode, timer, or air quality indicator to ease usability. At the end of the day, you only pay around $60 for an air purifier bundled with a set of carbon filters that cost 10 dollars annually. Hamilton Beach TrueAir is a true bargain and a great deal for a first-time buyer.
In short: A simple and capable air purifier under $100 with a cost-effective permanent HEPA filter. Fits the small budget requirement and works well in small areas. Dirt cheap to maintain if you don't mind the lack of supportive features.
- Less than 100 for washable air purifier.
- Reusable and washable HEPA-grade filter.
- Carbon zeolite filter.
- Replacement filter cost +- 10 dollars annually.
- Silent operation.
- Weak permanent filtration compared with a True HEPA filter.
- Less effective against strong smoke and odors.
- Basic unit with no add-on features.
You don't have to spend a lot of cash to enjoy the health benefits of clean air. LEVOIT Core 300 True HEPA is a budget air purifier under $100 with 6480+ Amazon reviews and counting. This award-winning air purifier is completely designed in South California with a modern and minimalist approach. The perfect gift for Californians that are troubled by the yearly wildfires.
At 8.7 x 14.2 x 8.7 inches, LEVOIT Core 300 air purifier is not the smallest, but portability will never be an issue. The 8.8 pounds weight is on the heavier side but you can still effortlessly carry it around. Build quality is top-notch despite its price range. The AC capacitor motor uses durable high-precision bearing surrounding by abrasion resistant materials. With Levoit trusted 3 million customers worldwide, we expect this air machine to last for years to come.

- Air Filtration - Pre-filter, True HEPA filter, Activated Carbon Filter, Specialized filters
- Noise Level - 24 – 50 dB
- Warranty - 2 years
- Coverage Area - 219 sq. ft.
What makes LEVOIT Core 300 great is the Holy Grail filtration that consists of a pre-filter, H13 True HEPA filter, and activated carbon filter. The pre-filter will trap the biggest particles in the air like dust, hair while extending the life of the other filters. Unlike some models that cheap out with HEPA-type filter, LEVOIT Core 300 uses a H13 True HEPA filter that removes 99.97% of fine impurities e.g. mold, pollen, pet dander, fungi, and germs irritants down to 0.3 micrometers. The granular activated carbon filter neutralizes common smoke and odors in a household. For advanced filtration, upgrade to the optional Pet Allergy Filter that is super effective against pet odors, diapers, higher-grade Toxin Absorber Filter that specializes in air pollution like wildfire smoke, vehicle exhaust, volatile organic compounds (VOCs), or MB Filter that neutralizes germs and impedes their growth. Removing harmful contaminants would be a piece of cake.
No surprise that LEVOIT Core 300 has built its own fan base and rightly calls for a spot here. VortexAir technology creates a cyclonic airflow system that delivers a quick 12 minutes of air circulation. At high speed, LEVOIT Core 300 offers a mid-range purifying radius that covers up to 219 square footage at 5 air changes per hour. Ideal for bedroom, office, living room, nursery, kitchen, and basement. Clean air delivery rate CADR is equally impressive with dust rated at 140 cfm, pollen at 145 cfm, and smoke rated at 141 cfm. The higher the CADR, the faster the air purifier can clean the air.
LEVOIT Core 300 is not shy about features too. You have an auto-off timer that can be set to turn off the air purifier after a specific number of hours. The handy child lock is also present to lock the controls from meddling children and filter life time indicator reminding you to change the filter. A rarity feature for an air purifier below 100 price point, LEVOIT Core 300 is also backed by a 5 years warranty with California-based customer service.

Nevertheless, Levoit Core 300 is still cost-efficient enough for long haul operation.
Nitpicking on a few tiny problems, the small filters have a shorter 6-8 months of lifespan. Not ideal but far from worst either. Expect to pay 20-40 dollars on the filter replacement cost. Built-in sensor, Auto mode, AQ indicator is also not present here. Top up a little more, there are other inexpensive air purifiers that come with everything you need. If you plan to move up from Levoit stable line in the near future, you know what to look out for.
In short: Affordable HEPA air purifier under 100 with decent airflow performance and backed by a 5 years warranty. Great for households that are dealing with specific types of pollutants.
- Budget-friendly 3-stage HEPA air purifier.
- High CADR and purifying coverage.
- True HEPA filter.

The phrase what you paid is what you get does not apply to Levoit LV-132. A budget-friendly air purifier (around 80 dollars) with the deal clincher nightlight. The nightlight is a useful feature to prevent you from tripping over objects when trying to navigate through the dark. If you have toddlers at home, the nightlight will help the little ones sleep comfortably at night while it cleans the air. With 2 adjustable brightness settings, you can reduce the light intensity or turn it off during day time to extend the lightbulb usage life.
Other than that, Levoit LV-132 is a basic HEPA air purifier under 100 price range. It is an ozone-free, UL listed, and CARB compliant model trusted by millions worldwide. The 3 selectable speed is easy to use despite the lack of Auto mode, timer. A filter change indicator is also available for added convenience and 2 years warranty with California based support for extra assurance. On the whole, Levoit LV-132 passed our test on durability and reliability. The 9.7 x 14.6 inches height and 9.8 inches compact body frame is well-built with no signs of uneven gaps. The compact and contemporary design with a modern vibe makes it easy to fit in tight spaces and home decor. Moving from room to room can be done with minimal effort. Place it anywhere in your home to restores the freshness in the air.
Levoit LV-132 offers a competitive specification that is no easy pushover as such:
- Filtration Type - 3-stage
- Air Filtration - Fine Preliminary Filter, True HEPA filter, Activated Carbon Filter
- Noise Level - Less than 43 dB
- Warranty - 2 years
- Coverage Area - 129 sq. ft.
Here's the reason why this is the best air purifier for smoke under $100. Powering the machine is a 3-stage purification that includes a fine preliminary, mandatory HEPA, and carbon filter. The fine preliminary filter AKA pre-filter traps large particles like dust, hair, debris, and protect the inner filter. The well-protected True HEPA filter traps 99.97% microbes and allergens that cannot be seen through our naked eyes including dust mite, dander, pollen, mold, and bacteria. The last-stage carbon filter reduces gaseous compounds and household odors that we might not realize it is degrading our indoor air. Ammonia, radon, VOCs, CO, CO2 are some of the toxic gases that will be removed by the air cleaner. Completing the filtration is a modest 129 square feet coverage suitable for bedroom, kitchen, office, and baby changing room.
Levoit LV-H132 is also great for a restful sleep after a long day. Virtually silent, the noise level is less than 43 dB and can go as low as 25 dB. Unfortunately, Sleep mode is not available but at least you can turn off the nightlight for less disturbance. The average 28 watts power consumption is efficient compared with other electronic appliances. You can safely run it all day every day without fail.
As for limitations, the small filter size and 6 months lifespan are unavoidable given its compactness. The 129 ft2 coverage and 110 cfm CADR is not great but workable for a small purifying area with no major indoor pollution concern. You could do a lot worse for the price you paid. Like most air purifiers under 100 here, Auto mode is omitted due to the lack of a dust sensor. That said, Levoit LV-132 is ideal for a person that has breathing difficulty or allergies due to bad air quality. Even though pricing is slightly higher compared to other entry-level air cleaners, it is still below the $100 benchmark. We appreciate the inclusion of a True HEPA filter and a dedicated carbon filter despite the limited space.
In short: America's NO1 best selling air purifier brand. A capable HEPA air purifying machine with a low price tag and a lower filter replacement cost. Odor removal may not be its strong suit, the all-around purification will make up for it.
- Less than 100 dollars after discount.
- True HEPA filter.
- Activated carbon filter.
- Silent operation with low energy usage.
- Optional night light.
- No sleep/ auto mode and air quality indicator.
- Short filter life (6 months).
An air purifier that doesn't look like one is probably the greatest compliment we can give TREDY TD-1500 air purifier.

The 8.5 diameters, 15 inches height, and 6.6 lb weight are perfect for room to room purifying. You can proudly place it on the work desk, bedside stand, cabinet, island table, and walk-in wardrobe. The surrounding air ventilation will efficiently draw air in while the top air outlet will push clean air upwards.
Staying at the top, TREDY TD-1500 comes with full-fledged controls in spite of its cheap price tag. You have 3 speeds plus Auto mode for autonomous purifying according to room air quality. At the center of the controls, you have an air quality indicator light that will change from pure air (blue), good (green), normal (orange), and polluted air (red). Filter change light will remind you to change the cartridge when the filter is dirty. The 3 pre-set timer (2/ 4/ 8 hours) can be set to turn off the device after running for a specific number of hours.
Sleep mode is perfect for bedside use as it will turn off the light and clean the air silently at whisper-quiet 28 dB. The Night light comes with 2 level brightness that can provide comfort and security at night without disturbing your sleep.

The second-stage True HEPA filter will trap 99.97% tiny particles as small as 0.3 microns like mold spore, pollen, pet dander, and germs. The third-stage active-carbon filter will remove harmful tobacco smoke, pet odors, cooking smell, and VOCs from paint.

What Can A Cheap Air Purifier Do?
You don’t have to spend a fortune on an air purifying device. "Cheap" is a very loose term that would have a whole new interpretation for different sets of people. Let it be an air purifier under 200, 100, 50, there are still a lot of things a heavily discounted model can provide than just clean air.
Breathing in clean air can alleviate seasonal allergies like viral flu, asthma, and pump more oxygen into our lungs. Oxygen can help us being energetic, lower blood pressure, reduce stress, sleep better, and strengthens our immune system. In the long run, clean air can prevent sicknesses like COPD, pneumonia, bronchitis, dementia, and heart disease. The only key difference between cheap (poor quality) and price cheap is the end result. A budget air purifier can still provide exceptional value within its capacity. As a matter of fact, many of the best-selling models are typically in the entry-level segment.
Are Cheap Air Purifiers A Waste Of Money?
An affordable air purifier won't be a waste of money as it can improve air quality by removing airborne allergens, odors, and toxic gases. With the multi-level HEPA filtration, it can prevent respiratory illnesses, slow down dust build-up, stop mold/ mildew from spreading.
In general, the pricier the air cleaner, the better the specification. That is the rule of thumb although they are a few exceptional cases. If you can extend your budget, go for a higher-tier model. As an air purifier is a long-term investment, make sure you choose the right model regardless of the price point.
Cheap VS Expensive Air Purifier
Pricing, room size coverage, types of filtration, performance are the differences between cheap and expensive air purifiers. Starting with the pricing, most affordable air purifiers will cost $100 or less while expensive air purifiers will start from $200. For purifying coverage, most low budget air purifiers will cover a smaller room size between 60 to 350 square feet while expensive air purifying device covers a wider room space starting from 300 square feet.
A high-performance air cleaner can help capture all types of airborne allergens, smoke, and odors. There are some air purifiers that come with single-stage filtration. Avoid those. Instead, go with multi-stage filtration that maximizes the performance and guarantees your money’s worth. A HEPA-type filter can be found in the lower-range model while a True HEPA filter is used in more premium models. As for the frequency of filter change, anticipate a shorter filter lifespan between 3 to 12 months for a cheaper air purifier. Premium air cleaners filters will typically last for 12 months or higher depending on the filter quality.
Is it Safe To Purchase A Cheap Air Purifier?
All air purifiers that use mechanical filters are safe unless it is an Ozonator. An Ozonator or ozone generator produces harmful ozone that will damage our body's immune system and lung tissue cells. The safest option is to go with an ozone-free HEPA air cleaner. Via the internal motor fan, the air purifier will pull in airborne particles, trapped them on the HEPA filter, and circulate back purified air.
Do Air Purifiers Use A Lot Of Electricity?
An air purifier will increase your electricity bill by a very thin margin even if you run it every single day. On average of 12 hours daily operation, you will only see a monthly increase of $3 to $5 in electricity bills. That's only $36 to $60 dollars annually. For all-day 24 hours operation, just multiply the numbers by 2. The new monthly electricity bill will be $6-$10 or $72-120 annually. Take note that the electricity cost in the United States varies from state to state.
What To Look For In The Best Air Purifier Under $100
An air purifier is more than just a home appliance that catches airborne dust and allergens via the internal fan. It is a long-term investment for you and your family member's health. Given the tight budget, there are many factors to consider when buying an under $100 air purifier. To help you make the right call, here are the top features one must not overlook.
- Dimension - There's a saying, the best air purifier is the one that can fit into your home. As air cleaner comes in all sizes, knowing where you intend to use it can make a huge difference in usability. If you want to bring it around for trips, pick a portable air purifier that can be carried around easily.
- Room size - The air purifier filter size and airflow delivery rate will determine the coverage capacity. Most manufacturers will give an official figure on the air cleaning coverage typically at 2 air changes per hour and the recommended room size. Measure your room’s square footage and pick a model that can support that. For example, to cover an entire 200 sq. ft. bedroom, you will need an air purifier that has at least 200 square feet of purifying coverage.
- CADR - AKA Clean Air Delivery Rate is a metric designed by AHAM to measure the air cleaning capacity of a device on dust, pollen, and smoke. Regulate in cubic feet per minute, the higher the CADR, the quicker the air cleaner will be able to remove the airborne contaminants. Not every brand participates in this test due to some discrepancies in the testing.
- Filtration quality - A good set of filtration can protect us from inhaling harmful allergens, prevent asthma from triggering, and other lung-related diseases. The types of filtration can also determine how efficient an air cleaner is in removing fine particles. Going for an air purifier below 100, the 3-stage filtration is a must that consists of a pre-filter, HEPA filter, and carbon filter. Optional filtration like ionizer or UV-light is a big plus for a more comprehensive air cleaning.
- Filter usage life - Depending on the filter size and quality, a small filter usage lifespan will vary between 3 to 6 months with 12 hours of daily operation. For 24 hours of continuous operation, you should replace the filter when the filter change indicator is lit or when it is clogged with dust and other particles. The longer the filter lasts, the less maintenance is needed.
- Warranty - The telltale sign of how confident the brand is with their products is on the warranty period. As air purifiers will last for ages, pick a model that is backed with at least a 1-year warranty from the manufacturer itself. Go through carefully the after-sale service, labor, warranty terms, and replacement policy.
- Additional features - That enhance the air purifying performance or usability are welcome. Common features include Auto mode, Sleep mode, dust/ odor sensor, and timer. Uncommon features include a digital display, remote control, night light, and essential oil tray.
- No ozone production - Never purchase an ozone generator to clean the air in your home. Inhaling ozone will damage our lung tissue cells, aggravate asthma, and allergies. EPA recommends the ozone concentration level under 0.05 parts per million at home. So check carefully what technology is used in the air cleaner before making the purchase.
- Selling price and filter cost - Seek a balance between cheap and cheerful. Compare the package you will get with the competitors’ model. Also, account for the replacement filter cost. Match how many years does it take for the filter price to stack up and match the retail price.
