If you’re looking for a more inexpensive option, we recommend this best-selling model from Levoit. It’s powerful enough to refresh the air five times per hour, though it’s smaller size lends itself to working in rooms up to 219 square feet. Most models circulate air through a HEPA (High-Efficiency Particulate Air) filter, and often more than one. HEPA filters are certified to trap particulate matter as small as 0.3 microns, which covers dust, pollen and most bacteria. Some purifiers boast a medical-grade Hyper-HEPA filter that will go down to 0.003 microns — enough to pick smoke out of the air.
The Levoit Personal True Hepa Air Purifier traps pollution inside your home to make sure you’re breathing clean air indoors. It’s designed with three stages of filtration and three fan speeds ranging from light to heavy based on how much purifying you need at a given moment. In conjunction levoit air filter with this, the more high-tech air purifiers can employ an extra line of defense. Some models use an optional UV light that renders many micro-organisms sterile, and an activated charcoal filter that can actually pull in and neutralize toxins through electrostatic attraction.
The Inofia PM1320 claims to work in rooms as large as 800 square feet. Based on its specs, we determined that it’s appropriate for rooms of just 287 square feet . The mechanically identical Coway Airmega 400S, a “smart” version of the 400, costs a bit more and has levoit filter a very basic app whose terms of service ask for unnecessarily intrusive permissions. We don’t find it worth the money or the security concerns if you’re seeking a smart purifier with remote functionality and additional information; check out the Mila instead.
This unit is not equally efficient as the larger Levoit models but it does its job. As no two spaces are the same, we’ve put together a range of different Levoit air purifiers to suit varying needs. During our ambient air quality test in a 30m3 sealed room, we ran the purifier for 30 minutes at a setting lower than 50 decibels (at the third-highest fan setting). We found that the Levoit 400S absorbed an impressive 99.5% of particles smaller than 0.3 microns and 100% of particles smaller than 2.5 microns and smaller than 10 microns.
Reflects how intuitive and easy the controls are to use, carrying ease, ability to remove the filter, and filter life indicator. Negative reviews cite problems with the VeSync app and a lack of sturdiness in design. We had to reinstall it twice when it crashed over the course of our testing period. This could quickly become irritating for users who want levoit filter a seamless connection to their purifier via their smartphone. Use these items to clean your home’s air, reduce the sources of respiratory problems, and limit the infiltration of new particulates. The Oransi OV200 has budget specs, draws as much as 60 watts (our budget pick draws 34.6 watts on medium), and usually costs much more than our budget pick.
