The Instant Air Purifier AP 300 is another great choice if you have a large room. It has a large area for the filter, giving it an edge over the other air purifiers we tested that only have a small space for the filter to fit in. This means that more of the filter is exposed to air, meaning it can capture more pollutants.
The purifier comes with an ionic cleaner that neutralizes the air of the smoke and odors from cooking, pets, and other sources. It’s one of the few purifiers that let you wash the filter itself instead of just replacing it once it’s dirty.
This purifier is whisper quiet when turned on low mode and runs on medium and high, which are still quiet enough that they won’t wake children who need some help sleeping through allergies.
