Negative Positive
Title: Not very good, Don"t recommend
Review: I bought 2 of these a few months ago from another site. The concept sounds ideal but, 1. They make noise that sounds like bad fan bearings or something is not right. 2. Running 24/7 there is no difference in air quality. 3. They do trap a little dust. 4. They circulate a very small amount of air, not use full in a room 10x10 it seems. 5. They have had no effect on allergies at all. And no reduction in dust on surfaces.I have had holmes and honeywell in the past and even a very old norelco. They were all quieter, circulated more air, made a noticeable fresher smell, and reduced dust particles on dresser, computer, tv etc. And helped with allergies. None of these qualities have been found with the germ guardian.
Is the review positive or negative?
