Filtrete 3M Filtrete Device Ultra-Quiet Room Air Purifier FAP00 (8 Square meter), Eliminates Odor, White color, weight: 380 gr, size: 6 x 3 x 5 centimeters, 1 unit/box

This product is a cheap fan with a cheap filter put together with the 3M logo. The company to be blamed is 3M for allowing such cheap products to use their name unless they are a part of this.The issue with the above product is it touches the health of people and people buying it as being a good filter for some conditions will be disappointed not getting good benafit.If you want a good air filter buy a Japanese brand or LG and nothing else.
