Filters are actually a good idea but if such is really necessary ... ????

Heaters are safe dust magnet due to the air movement in the heat cycle. The is also important to the heat in the room leave and again the cold attracting and heat.
However, even in winter when they are used. To which there is in a room usually also add some other culprit attract or bind the dust.
Unfortunately, the product dimensions were only very small later in the Technical Reference. Details given (and as even the pack size 30,4x7,2).
According pack they are then only 30x6,5cm. Most radiators are but slightly wider.
It would be better when you see it at first glance up in the name of the product or size in the description otherwise we would have seen the same in width, unfortunately, are the stakes too small for our Standart-0815 radiator.
So they have we have passed us still cut at the end of only the smallest heater in the small guest bathroom.
The then how many radiators you want to assemble so you have to spend quite a lot but then.
The filters are made of a plastic Polyprobylen in a kind of honeycomb structure. They can be put on the radiator but it is better to lay them under the cover.
As a layman, I can not assess the impact. After 2 weeks of testing I find no visible discoloration in the filters.
The producer writes on the packaging of the filter 3 to 6 months acts. But what then is not so. Can I or do I have some dispose of it in the trash him. I rather think the latter.
In addition, you should yes to advise each heating fitter the surface of the radiator keep always nice free so that they also can heat well.

Not so great, I find the statement that one of dust is sick. What is clear is that it can cause allergies in some cases. But these are only certain ingredients such as pollen or house dust mites. I still have some of it never read the instrument of common house dust through the lungs into the bloodstream and then is worrying for our health. Are there rather a few exaggerated statements questionable. I wonder how in earlier times, the babies and young children have survived so completely without air cleaner and disinfectant.

Conclusion: one can try like and use the filter of Reer. Damage he certainly does not. But in my opinion, a normal grooming behavior, daily ventilation and a healthy and happy lifestyle is completely sufficient so the kids can grow up healthy.
