Bests & Worsts Reviews from Amazon

EDIT: I bought a third one of these in Nov. 2017, and I’ve been pretty disappointed in its performance. The old model was well made, and those 2 are still working great. I was disappointed to see that it has been re-designed, and not with good results. The new design seems much more cheaply made. It’s a lot lighter, and quieter. But it honestly does very little to purify the air. I won’t buy another one, that’s for sure. This is another sad example of a company taking an awesome product and completely ruining it with “improvements.” Give me the heavier, noisier product that actually cleans the air! I’m changing my rating from 5 to 2 stars. Old review: Bought one of these a month or so ago locally, and have been so happy with it that I'm here on Amazon buying another one for the second floor. It is extremely effective in purifying the air of dust and odors. It has made a huge difference in my allergies. Looking forward to having one cranking on each floor. The filters are rather expensive, but all HEPAs are.
