| Customer Reviews: Average Rating:  Rating : - Doesn't clean as well as hoped I purchased this off woot and got it new. After having used it for 5 days, I've noticed a few things.
This doesn't really clean the air, it mostly helps circulate it and remove larger airborn particles (such as hair). It doesn't clean air that well, since it pulls it in through the front (broad-side), but it has a plastic cover over the inlet, limiting it to the gap between the cover and base. The amount of "dirty" air it pulls in is severely limited, since the unit is so low to the air, and it blows it out the top, so if you throw a bunch of dust into the air, the purifier will push it around the room before it cleans it out.
3M did a pretty good job designing a cheap air filter that runs fairly quietly. Low is the only mode that I can call "quiet". mid and high are pretty noisy. Plus the wheel inside that's the fan wobbles, creating an oscillating hum. + See Full Customer Review |  |
