HEPA (high-efficiency particulate air) filters don’t capture volatile organic compounds . Some also employ a class of minerals known as zeolites, whose extremely fine pores allow them to function as molecular-scale filters. Our VOC pick has significant amounts of both activated carbon and zeolites. However, in the US air purifiers cannot be marketed as medical devices.
In order to clean the air, these appliances use filters and fans to remove particles and circulate the purified air back into the room. For example, the much-hyped, sleek-looking IKEA Förnuftig can only capture 99.5% of smaller airborne particles. Out of all the air purifiers we tested, theLEVOIT Air Purifier for Home Large Roomwas our favorite. It has an all-around great design with its effective air purification, intuitive levoit filter smart and app controls, quiet operation, easy setup, and attractive appearance. If you’re looking for an option with straightforward controls and instructions and don’t mind having a model with less cutting-edge features, theTOPPIN Air Purifiers for Pets in Bedroom TPAP001is our favorite budget pick. Most of the air purifiers we tested exhibited a considerable difference in noise level from the lowest setting to the highest.
Then we considered thedesignof each air purifier, looking at features like oscillation, type of filters included, timed settings, smart capabilities, and color options. Next, our testers measured thenoise levelof the air purifiers on their highest and lowest settings using a decibel meter. Our testers also evaluated all of thefeaturesavailable on the air purifiers and took time to evaluate their levoit purifier ease of operation and accessibility, especially if an app was available. While most air purifiers work on pet dander only, the Alen Breathesmart Classic claims to also filter out pet fur from the air, potentially preventing it from landing on your furniture, carpet, and clothing. This purifier is designed by NASA airflow engineers, which explains its modern and high-technology design.
However, if an automatic mode is essential for you, Levoit also offers a 300S model, which is identical in almost every way, with the addition of WiFi and a few other features. The only part of the Levoit Air Purifier that levoit air filter must be cleaned is the pre-filter. To do that, you only need to remove the filter, run it under warm water, and lay it flat to dry. First, the pre-filter captures large particles like dust, lint, fur, and other fibers.
Note that performance with bigger or smaller particles is even better. It’s compact size helps it to blend in, and the nearly silent operation won’t disturb you while you’re sleeping. Cleaning it only requires a quick wipe with a dust rag every couple weeks and filter changes are both super simple and relatively cheap. I set the schedule feature to turn the purifier on to the max speed every evening at 9pm.
All in all, the ratings and reviews Levoit LVH132 gets confirm this is one of the best overall air purifiers for the smallest rooms. Activated carbon filter doesn’t stop solid particles; rather, it adsorbs gaseous odors like cigarette smell. The ‘PUR’ series by Levoit has a 30% higher purification efficiency. In short, it removed odor and increases indoor air quality 30% faster than other standard filtration systems .
We ran this unit almost nonstop in a real-life bedroom environment and appreciated how we could set it and forget about it. Although the filter did not have a large amount of dust on it after an entire month of use, we still believe the purifier made some difference in the level of dust in the bedroom. Overall, this is a great value pick, considering its price tag, style, and effectiveness. We were slightly disappointed by the air purifier’s rather boxy appearance (though at least it is still clean-cut and sleek).
The filters on Levoit air purifiers are not washable and need to be replaced from time to time. Small and medium-sized Levoit filters last, on average, about 6 months, but for some larger models, the filters can last up to 8 months. Filter HVAC at MERV 14 or above are rated to remove airborne particles of 0.3 micrometers or larger. A high-efficiency MERV 14 filter has a capture rate of at least 75% for particles between 0.3 and 1.0 micrometers. Although the capture rate of a MERV filter is lower than that of a HEPA filter, a central air system can move significantly more air in the same period of time.
