Bests & Worsts Reviews from Amazon

If you want a silent, useless air cleaner, go buy an overpriced oreck or sharper image unit. It will reduce things like smoke and tiny, tiny particles, but forget it getting rid of dust. I know, I had one. If you want a unit that actually "Filters" the air, buy this. Sure on Medium or High this unit will add background noise, but on low, it is hardly noticable if it's not right next to you. We noticed an immediate "crisp feel" to the air and huge reduction in dust in the air. My cough of 3 weeks is gone overnight. Coincidence.. I think not. Don't read into the reviews that bash the noise.. Noise means it's working.
