Best humidifier / vaporizer on the market We have the power now since 12.06.2013 in constant use, our apartment has 86 m2 and had no Philips HU4803 / 01 always below 20% humidity. Since 12/10/2013 we remember about the first wow effect until properly, the air is almost as rain as after a day very pleasant. Also in the bedroom recovers you look better than ever before. And I must say, we always tipped the window at night. But with the evaporator it breathes just easier, no idea why, it just is :-) To care for: I wash the containers daily.

Rinse the container incl. Interior with water. (qid = 1390693254 & sr = 8-10 & keywords = sp% C3% BClmittel) and a sponge, and then the whole thing with detergent (qid = 1390693391 & sr = 8-3 & keywords = + Vileda sponge) thoroughly clean. This leaves the whole about a week fresh The filters I have to say, other companies charge twice as much! I have all the equipment looked at where there is time. From 100-400 but can not cover this price / performance spectrum all. So 5 stars [...]
