This air purifier has blown away my expectations. I have three large senior dogs and my house literally always smells like dog, no matter how clean I keep it and how many candles I burn! Almost immediately after plugging this in my house smells so fresh and clean! I’ve been using it for a few weeks now and I haven’t even had to put a new filter in yet. I noticed whenever I turn on my air fryer the air quality goes down dramatically and then slowly rises back to 100, so clearly it’s doing a great job. Just totally in love with this thing! Highly recommend!
