Bests & Worsts Reviews from Amazon

I bought this air purifier after months of researching for a way to eliminate second hand smoke odor. My husband & I bought our first place, a condo unit, without considering our neighbors who smoke on either sides. I cannot stand the smell of cigarette smoke nor the stale smell that seeps through the walls and vents. I was worried we made a bad choice buying this property but I was determined to find a solution. I decided to try this purifier since some reviews mentioned it's effectiveness removing cigarette smell, plus the filter is washable so it is economical. I have to say within 24hrs of having it on we noticed a great improvement in the smell. We have to leave it on 24/7. We usually have it on medium & it doesn't impact the electric bill as much. We have one purifier for our 2 story apartment & we have it by the stairs. In addition to it, I bought carbon filter sheets at the hardware store for some of the vents were I noticed cigarette smell seeping in. The combination is life changing!
