Negative Positive
Title: I now have two!
Review: I recently bought a second unit for my Baby daughter as we have smokers in adjacent apartments and their smoke gets into our own apartment.These air filters are the best in their class that I have ever used and they really make a big difference to air quality, even adding negative ions to the air which make the air so much sweeter to breathe and also allows you to sleep better. They can be set to be ultra quiet at night, which is great for scrubbing the air whilst you sleep.As for my smoke problem, these will scrub the air clean of smoke and other odors, also removing dust and allergens. I really wish they would pass a law making it illegal to smoke outdoors in apartment complexes but until that happens, this is the only way that I can get clean air back into my home.
Is the review positive or negative?
