In Auto (similar to medium; the Air does not contain a particle counter to adjust to air conditions, but instead asks you to enter the approximate size of your room, after which the machine chooses a fan speed that Molekule deems appropriate), the air performed worse, reducing particles by 0.3 microns at only 18.0% (ambient) and 26.4% (clean). In Silent, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). And in Dark plus Auto, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, it reduced them by 21.3% (ambient) and 18.0% (clean). Interestingly, those numbers closely reflect our results in automatic configuration with the PECO system activated, suggesting the possibility that the Molekule Air depends mainly on its physical prefilter, not its patented PECO mechanism, to remove particles.
This Levoit air purifier is a Good Housekeeping seal holder, thanks to its combination of value, performance and intelligent design. In particular, the unit's three-stage filtration, which includes a true HEPA filter, helps capture even the smallest airborne contaminants in rooms up to approximately 400 square feet. A built-in precision laser sensor accurately monitors particles in the room and automatically adjusts fan speeds as needed. The purifier is also incredibly quiet, it works at only 24 dB, which you will appreciate if it is placed in your bedroom.
One of our staff evaluators has been operating the unit for several months at home and says that the light hum is quite quiet at night. Then there are intelligent capabilities, including the Levoit app, which allows you to monitor air quality in real time, view filter life, and set schedules. By Lou Mudge Joanne Lewsley Contributions Published July 29 22 The Levoit 400S performed better at removing airborne particulates in our home tests, capturing at least 99.5% and up to 100% of particles during testing. A companion application that users can download provides useful data on air quality and allows users to program and program the air purifier to fit a busy family schedule.
Unfortunately, despite its great functionality, the VEsync application was not always reliable. During the course of our testing, we had to uninstall and reinstall the application twice when it crashed. The Levoit 400S's quieter setting is barely noticeable, while the more powerful setting still registers only 52 decibels. Sleek, quietly powerful and with an intuitive and easy to use intelligent interface, the Levoit 400S is our best selection of air purifiers.
It could be the ideal appliance for you if you are looking for an effective air purifier that has great performance but doesn't break the budget. The Coway-AP-1512HH air cleaner also benefits from a built-in particle sensor. This means you can get an idea of the air quality in your home with the color coding system on top of the device. It will show a blue light when the air is clean, purple to indicate pollution and red for high pollution.
Another smart feature of the Coway AP-1512HH are sensors that can adjust fan speed to keep the air clean, so you don't have to alter settings. We especially liked the Eco Mode of the Coway AP-512HH, which worked well to turn off the air purifier when air pollution was low, saving energy and money. Our tester also found that the automatic mode worked well to toggle between fan settings based on indoor air quality. The Coway AP-1512HH is an air purifier suitable for small room spaces up to 361 square feet, making it suitable for smaller spaces and bedrooms.
If you need something for a larger room, then you might want to look elsewhere, considering that this is a fantastic option for smaller spaces. The Dyson Purifier Cool is one of the most elegant air purifiers on the market. Its unusual design makes it a talking point in any room, while simple but cool extras like a magnetic remote control take it one step ahead of an average air purifier. We burned a series of matches to check how well the purifier captures the particles.
At a level 6 setting, we found that the purifier removed 98% of particles smaller than 0.3 microns, 72% of particles smaller than 2.5 microns, and 73% of particles smaller than 10 microns. At a level 10 setting, we found that the purifier captured 95% of particles smaller than 0.3 microns, 96% of particles smaller than 2.5 microns, and nearly 100% of particles smaller than 10 microns. The Dyson Purifier Cool's high price tag may be too expensive to fit everyone's budget, but its sleek, sleek design and smart, connected functionality are impressive. Our home tests found that the Blue Pure 221 was consistently better than all the other air purifiers we tested.
Despite its lack of Smart technology, it outperformed purifiers at almost double the price. We burned a series of matches to check how well the purifier absorbed the particles. In a Level 2 setting, we found that the purifier absorbed 99.7% of particles smaller than 0.3 microns, 99.5% of particles smaller than 2.5 microns, and 100% of particles smaller than 10 microns. In a Level 3 setting, we found that the purifier absorbed 99.9% of particles smaller than 0.3 microns, 99.6% of particles smaller than 2.5 microns, and 100% of particles smaller than 10 microns.
Small enough for any desk or shelf, the Levoit H132's compact size and low price make it the ideal air purifier for someone who wants to try their first air purifier at home. If you have a small apartment, or just want to use an air purifier only in one room, this could be the product for you. Unfortunately, the Levoit H132 did not live up to expectations when it came to testing how well it absorbed particles, steadily falling below the 99.97% expected of a device with a HEPA H13 filter. However, running the purifier for longer periods can produce better results.
The Levoit H132 may not have all the details of a smart air purifier, but its affordability and compact size make it the ideal beginner's indoor air purifier that works well in small to medium sized rooms. Lightweight and compact, the KOIOS EPI810 is the smallest air purifier we've ever reviewed. It will sit comfortably on any desk or office shelf and its 2.5 lb weight makes it light enough to take on the road. Our at-home incense smoke test evaluated how well the purifier worked after burning five incense cones simultaneously and found mixed results.
While the KOIOS EPI810 absorbed an impressive 99% of particles measuring 10 microns, it only absorbed 52% of particles smaller than 2.5 microns. While it doesn't have the surprise factor when it comes to the design, or sophistication of a smart, connected air purifier, the KOIOS EPI810 can work well if you want something easy to operate. However, a louder, louder fit and mediocre performance in our at-home tests may discourage some users. It's not yet clear if air purifiers are doing anything to prevent the spread of COVID-19 indoors.
The Center for Disease Control (CDC) advises that you open doors and windows to maintain good indoor airflow if the weather permits, of course. HEPA filters, found in some air purifiers, have been found to remove some viruses from the air. You'll notice that most of the room air purifiers we tested have something called a high-efficiency particulate absorption (HEPA) filter. These can remove 99.97 percent of air pollutants 0.3 microns in size, which basically means they're really effective at removing most indoor air pollutants.
For context, most dust particles are approximately five microns in size, and pollen has a staggering 10-1.00 microns, all of which a HEPA filter can trap and remove. Perry tells Live Science that while the most effective air purifiers can remove many different types of particles, you'll never get 100% pure air.

He holds a bachelor's degree in creative writing from the University of Bath Spa, and his work has been featured in Live Science, Tom's Guide, Fit %26 Well, Coach, T3, and Tech Radar, among others.
He writes regularly on topics related to health and fitness, such as air quality, gut health, diet and nutrition, and the impacts these things have on our lives. This three-stage air purifier combines mechanical filtration with an electrostatic filter and, to reduce odors, an activated carbon filter. To clean the air, these appliances use filters and fans to remove particles and circulate purified air back to the room. Similarly, you'll want to keep an eye on the clean air supply rate verified by AHAM, which tells you how much air a purifier can process in a given period of time.
Some media outlets have incorrectly stated that HEPA filters do not filter below 0.3 microns and therefore cannot capture airborne coronaviruses. If you have specific concerns about VOCs, the HM400 is by far the best portable air purifier we've found. While this particular air purifier may lack the HEPA filter that gives premium air purifiers their quality mark, it comes with a built-in dimmable nightlight, making it an ideal air purifier for a nursery or children's bedroom. In fact, our years of testing have shown that any properly sized purifier will distribute filtered air evenly, in the farthest corner of a room.
It measures approximately 27 inches high and 18 inches wide, with a control panel at the top that includes an air quality indicator light that always reflects the purity of the room's air in real time with an easy-to-read display. Air purifiers often have a fan that moves air through a filter, removing impurities from the process, says David B. . .
