As of now, the filters themselves have a filter sorted by type. Pure materials, had mentioned it briefly earlier. Here is an example, although this surface treatment may not immediately give the impression of a single-type material, if you look at the cross-section of this material, it consists of one hundred percent of the same material, in this case a beautiful fit for the health of your home, a pine wood. It smells lovely here right now. So here I smell the healthy properties accordingly. We'll talk about pine wood again very briefly later.

Pure materials have the advantage in many areas; we had it before in terms of full declaration. The fact that this is of course significantly easier to evaluate these materials on the one hand, and on the other hand, if you now think of the topic of circulation, the purer a material is used, installed, used, the easier it is to use it in the cycle.

Correspondingly important filter by type.
