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. After careful testing and consideration, these are the best air purifier options according to our research.
Any of the air purifiers below should improve indoor air quality, filter out smoke and particles in the air, and at the same time provide fresh air. While ion filtration technology is not a big advantage, it also doesn't produce significant ozone, as tested by the California EPA. If you want an air purifier for a medium-sized room, the Coway HEPA air purifier is one of the best air purifiers with one of the most adventurous looks. The Blueair Blue Pure 411 is a simple and straightforward purifier with a smart design and a good investment. You get particulate and carbon filtration (activated carbon filter removes odors, pet dander, airborne allergens, and airborne gaseous contaminants) that will work well in a 160 square foot room, making it the best overall air purifier for rooms small. Some devices, such as the Sharp air purifier, don't even offer as much cleaning power at almost double the price. Okay, if you have the money and want a super-powered air purifier or if you prefer a purifier to cover your entire house than buy one for each room, then the Coway Airmega 400 could be the best air purifier for you.
This thing costs a dime but you get 1,560 square foot air cleaning coverage. It's also important to note that many of the best air purifier models I tested have been going in and out of stock in recent months given the demand for such devices during the pandemic and in the midst of wildfires. While that could mean that some of the above options are out of stock we've decided to keep our recommendations (and the reasons behind them) published so you can use them and find the best product for you. However for now our recommendations for the best air purifier options are based on their included prices and we recommend avoiding sellers offering the same devices for significantly different prices. We will update this list regularly as we review new products.
For the above devices I mainly considered power for price (i.e.,the higher CADR and lower price being better). Secondly I looked at additional cleaning modes usefulness of controls overall design and noise level. The best air purifier looks elegant enough to fit most modern decor can work as desired with minimal manipulation and can clean air thoroughly and quietly. As you read our guide you can notice that most of these air purifiers on list contain something called high-efficiency particulate absorption (HEPA) filter.
HEPA filters can remove 99.97% of air pollutants 0.3 microns in size making them ideal for removing most indoor air pollutants. For context most dust particles have size around five microns pollen has huge size 10 to 1000 microns all which HEPA filter capable trapping without any problem. Perry points out that most effective air purifiers will remove different types particles from air but they can never get it 100% “pure”. The idea of an air purifier is that it is designed to remove impurities from your home such as dust odors pet dander smoke bacteria viruses he says.
Indoor air much higher than outdoor air goal for air purifier neutralize these unpleasant things in your home. It works by having fan that draws air inside house into filters that remove impurities before returning clean air to room. However it is important to note that it is impossible to remove all particles that can live on walls carpets bedding hard surfaces. The Levoit 400S performed best in removing airborne particles in our home tests capturing at least 99.5% up to 100% particles during testing.
The Coway-AP-1512HH air cleaner also benefits from built-in particle sensor. This means you can get an idea of air quality in your home with color coding system on top device. It will show blue light when air is clean purple indicate pollution red for high pollution.
