Review on Purifiers Fragrance Purifier Effectively Pollutants by Catherine Buhr

I tossed between 3 and 4 reviews. Pros: Got two for a reasonable price. Looks nice. Smaller/more compact for a table or can stand on the floor. Three speeds - level 1 off (which also means no air circulating). Child/Pet Lock Button. You can turn off the blue lights that show the speed level. Cons: Low, very low (says it's disabled for some reason - not much circulation). The middle one is a bit noisy. The high is really loud. It's good to have white noise, but not for TV and the like. Is working? I'm still not sure how I feel about how well the purifiers work. It's basically a filter fan. If you have a small, poorly maintained area, this can really make a difference. We personally have not noticed any change in allergies etc. I feel better turning it on when my kid friends are away (maybe at least helps air circulation/prevents germs from spreading?) We use this in the bedroom, overnight low. The average seems to be a bit louder than normal fan noise. I wish there was something between low and medium speed. The other is in the family room which I turn on when needed. The filters seem easy to replace and easy to buy. All in all, this is a good buy.
