You should look for an air purifier with a smoke CADR that’s at least two-thirds of the room’s square footage. Manufacturers often list a recommended room size and a CADR score that are based on the appliance changing the air 4.8 times per hour. To test the best air purifiers for pets, we assembled a team of experts to use 38 different air purifiers in our lab in Des Moines, Iowa. During testing, we placed each air purifier in an enclosed space, then added smoke and pet hair to the room to see how quickly the air purifier was able to remove harmful particles from the room.
Trying to save money by purchasing a smaller air purifier than what you actually need will just give you disappointing results. It comes with a higher price tag, but can also tackle more space than other, similarly-sized air purifiers on this list. In terms of additional functionality, the EverestAir Smart True slides side to side on caster wheels, and includes an adjustable levoit filter vent fan, allowing it to be tucked under certain spaces such as kitchen counters without disrupting its efficacy. The clean air monitor display also gives a satisfying percentage reading of the air quality. In our lab test, the purifier cleansed the air pretty quickly on low mode; on the high mode, it immensely improved the air quality within five minutes.
However, this was a minor inconvenience given the usefulness of the in-app features. In testing, we noted how convenient it is to monitor the air purifier on your phone. The app clearly indicates the quality of the air in a space, and it can also remind you when to change the filters. We appreciate that in addition to an auto and sleep mode, this product also has an eco mode that runs only when it detects a decline in air quality. For assembly, we only had to remove plastic from the filter and insert its electrical adapter; the instructions were straightforward and easy to follow. Once the unit was up and running, we affirmed that it improved air quality within five minutes on the high setting and ten minutes on the low setting.
You also needn’t worry about it being an eyesore, since it has a sleek silhouette and futuristic design. In terms of its noise level, this purifier has a sleep mode for quiet operation while you rest, but we found it’s still incredibly quiet on low mode. As Levoit’s mid-range unit from the celebrated Core range of purifiers, the 400S is the ideal unit for the average home. Best suited to medium to large rooms, this purifier comes with a pre-filter, H13 HEPA, and Activated Carbon filters to tackle a whole host of pollutants, marking its impressive performance with a clean air delivery rate (CADR) of 260 CFM. As no two spaces are the same, we’ve put together a range of different Levoit air purifiers to suit varying needs. Whether you’re looking for a unit to target smoke or dust, for use in an open-plan space, to sit on a tabletop, or perhaps you’re looking for a purifier with the latest smart features, we’ve got something for everyone on this list.
Basically, that corresponds to bedroom, living room, and open-floor-plan combined spaces, respectively. In simple terms, ACH represents how many times a purifier can circulate the volume of air in a given room in 60 minutes based on its maximum airflow, and it provides a standardized baseline for categorizing and initially comparing purifiers. We set 4 ACH as the minimum for a purifier to be considered adequate for each room size. Based on our years of real-world testing, we know that 4 ACH ensures rapid and nearly complete cleaning of highly and continuously polluted air—a big concern during, say, a nearby wildfire. The cylindrical unit is compact—just 6.5 inches in diameter and 10.4 inches tall.
Prior to conducting our product test, considerable research went into deciding which air purifiers to test. This model relies on an H13 True HEPA filter and offers you three fan settings to choose from. Where the 300S differs is with its range of advanced smart features that will enable the user to operate the unit in new ways and learn more about your environment’s air quality. Perhaps the best smart feature comes from Levoit’s AirSight™ Plus technology. This enables the purifier to monitor the surrounding air and provide real-time air quality updates through its color-coded display and more detailed feedback through the Levoit app.
Department of Energy, which means it can remove at least 99.97 percent of particles in the air. Three filtration stages ensure your air is pollutant-free, including removal of bacteria and pet dander from the air. The three fan stages are quiet, although you’ll get a subtle fan noise at higher speeds. The second crucial step in cleaning your Levoit air purifier is removing the filter. Usually, air purifiers come with two filters but some purifiers also have three filters. As far as cleaning the levoit air filter is concerned, every brand offers its own set of instructions.
In addition, try to keep the devices as close to the modem as possible, especially if you are using a 5GHz modem, which has a much lower range by default. If none of this works, try using a hotspot from another smart device as a modem to connect the VeSync app and the Levoit device.
