Good start, but too expensive

The installation is very easy. The air filter is magnetically charged and attracts the dust. He reminds me of this Swiffer cloths that also suck the jam. Of course, the apartment is not completely free of dust. That's what I never expected, firstly because the filter is too small for, second, the heater is not continuously and third would be a sterile environment for the residents not good because you do not go in a bubble, but the immune system is only set up can when one is exposed to from time to time attacks healthy.

The filter can be cut easily, can be either placed on the heating or be even better placed in the heater. However, it is not economical support. In any heating at least one filter may have to be placed and then has to run on medium thickness.
