I've only had the Levoit for about 4 months and love it so far. The low and medium settings are so quiet; the high is a little noisy, yet still quieter than the medium and high on the 2 other air cleaners/filters I have, Germ Guardian. They're very good but I never knew Levoit would be better. Plus, the air comes up through the top to distribute up and spread outward. The others (G.G.) I have kind of shoot air out a small section of one side of the tower. I have allergies, a dog, and carpet (yuk, not my choice) in my apartment The Levoit helps keep the air much fresher/cleaner. I don't use any of its modes or timers. It's going 24/7. Apartment leasing manager came in to check and schedule a maintenance need and complimented the Levoit on giving refeshing air.
