Review on Air Choice True HEPA Filter Air Purifier: Removes 99.97% of Dust, Smoke, Odor, and Pet Dander - Ozone Free, Portable and Whisper-Quiet (25dB) for Allergy Relief by Katrina Davis

I'm Californian and will probably stay as long as I can, but I've learned to live and work indoors with a good air purifier. . Here in Los Angeles the air quality (unfortunately due to wildfires) was so bad that I felt nauseous, my throat burned, I couldn't sing and worst of all, I had severe asthma. And that in an air-conditioned room. This is my first air filter and I bought it thinking I'd just return it if it wasn't great. Within an hour of turning it on, my symptoms were gone - so fast! Instead of returning it, I advertise it to friends and neighbors.
