We have been given a BWT water filter. For this purpose we bought these filter cartridges. They fit perfectly and can be easily inserted into the housing. And then the water is filtered. What else can not the cartridge. Well, you can still train throwing it. But will you do it? Nope, they should filter the water. And it does perfectly. No disturbing off-flavors in the filtered water, no streaks, just crystal clear water. And social dating also. The trickles not to himself, but lets the water run through quickly pleasant. If you as time has just fancy a coffee and the filter is again filtered as usual in this case, then one does not have to wait forever until the necessary amount of water. That's in no time. More could you want? Sure, of course! As always, the lottery numbers from next Saturday. But even that can not betray the cartridge, because they do not know. So bleibts the filter and they can exceptionally well. Thus: strong buy recommendation!
