After a few minutes of analysis, not surprisingly, he told me that the air is polluted my office. The witness of a beautiful red. The blower will sound and the device turns the fan for an hour thoroughly. Then, after more than an hour, it slows down, the witness becomes ocher (poor air) then quickly blue (air cleared). The cycle ends with a rattling noise (the device sends negative ions into the room to prevent the suspended particles pollution source) then he is silent and runs at low speed.
When you are in the room, you do not feel anything in particular except that the air does not vitiate. Working in a noisy environment, I can not open the window constantly. But in general, we feel the need to air regularly in the day to avoid headaches: there, nothing like that.
I did the test by letting the camera night in a room, then coming back the next morning, I felt, anyway, a slight odor, but in the background, more heavy air, more responsible not dust but other things, making unpleasant if you think about it the environment in which it operates. And there is nothing in the background, almost sanitized air, much like when you go to the mountains or the sea and you feel that the air is different.
I am conquered by this unit, which does not prevent me to air but which makes the breathable air. Usually, in Paris, I always have a runny nose a bit, well, for four days that I use, this is no longer the case. I want to think it is from this unit that really cleans the air.

It is sold on the same website Fellowes Pack 4 Carbon filters for air purifier DX5 to 21.97 when the HEPA filter, which changes once a anFellowes 4 Pack DX5 HEPA filters for air purifier to 24.90 but then by 4 so you have for 4 years. Anyway, indicator lights tell you when to replace filters.
