Review on 🌬️ Highly Effective Air Purifier for Homes with Smokers and Pets, Powerful H13 True HEPA Filters for Reducing Pet Dander, Dirt, Pollen, Wildfire Smoke, and Air Pollutants. Quiet Air Cleaner for Bedroom, Office, and Kitchen, Operating at 28dB by Shannon Hernandez

I have three different unbeaten air purifiers and this is the quietest of the three. I hardly notice it's on unless I crank the speed to max. If you're not a fan of bells and whistles (WiFi, touchscreens, etc.), then this model is for you. I placed it in my entryway that spans the dining room and kitchen and it seems to do a good job in those spaces (about 500 square feet). Unlike some others I have, it occupies a bad area in front of the car and distributes clean air to the rear, so placing it with free space around is important. Really like this!
