Of course, the whole house has been cleaned and restored, but in the fine interstices of the radiator I was quite skeptical about whether they are really absolutely soot-free.
The filter system seems to me in principle a good thing to be. Actually, I have always wondered, why is not such a thing on the part of the radiator manufacturers supplied the same in kind.
As much as it meticulously cleans also throughout the house, in the fins of the radiator is not really good inside, so there are inevitably polluters. It remains dust hanging in it, which is logically swirled up during the heating season by the circulation of heated air over and over again.
The design of the filter I find, however, in need of improvement and well priced not necessarily appropriate. It looks just yet about by cheaper per meter, which you pay for relatively expensive as a quarterly to half-yearly change is required (which, however, is a subjective impression, because I not an expert in the direction bin production technology). The problem is that the filter in no radiator fit really well in the house with us. In a nursery of the radiator is much deeper, so I have to put in two rows each with 5 filters side by side two filters in succession and thus. The mach 10 filters (3 are in the package) for a radiator. Expensive pleasure.
In the second nursery 2.5 filters fit side by side. That's ok, but it remains in the depth of small columns for which it does not pay to cut another filter. But gaps remain so through the unfiltered air comes.
In the bedroom again the deep problem. More than two filters in succession. In the hallway of the radiator is narrower than the filter, so you have a lot of wastage.
Installation is basically good to see quite easily and in the product video, but a different product form in walls or similar would be better. Our radiators are fairly new and not any special.
We are now all radiators, for these filters therefore are suitable to equip and hope that this added a heating season. At the discoloration should one can recognize when a change is necessary. But that can be very well go to the money.
Postscript:
We have the filter now uses three months and it's been frightening, as they have become gray. Therefore probably remain of the filter function produces a good product, but above problems and unfortunately also the price.
