The product looks perfect

Stuffy nose, itchy eyes, what solution? Antihistamines ... I tried for several years hepa filters and ionizers. it does not work but it brings a totally better. The problem is the cost of the device to purchase and also the interview with filter changes. The permanent fan noise is also a problem. But this problem is partially solved with this model. Indeed the three available speeds the special night speed is really perfect. The device is idling but silently. No discomfort even to sleep next door. Air is drawn through the front of the unit but in the periphery and it is expectorated from above. This creates a slight air current proportional to the set speed. Nothing very embarrassing and it must circulate the room air to filter it. The filters are already in place on delivery but it must open the unit to unpack them before putting the device in operation. It's very simple and fast tool not need. Pressing on, we choose the speed and go. We can also schedule shutdown through integrated timer. I think the device is effective but I like it is he himself who evaluates the quality of the air I can not certify it. What I can assure is that the air is filtered through three filters before returning to my room. And ambient dust workpiece is visibly laid upon the first filter thickness I then removed with my cleaner. I guess micropoussière and pollen is deposited on the other filters below which are thinner. But there must be changed when the device indicates that it is necessary. There must be an integrated set wear count. And it should cost 80 euros. ; = RefRID 12NHEGR1GZJTH9FF4DSR
