Apart from the fact that this cartridge is added every few hours, also gently shaking almost inevitably leads to damage and the cartridge is incredibly expensive, everything is wonderful.
Again in clear:
- Is (to) added quickly
- Provided with predetermined breaking points, so that re / is difficult impossible
- The money for NEN piece of paper with plastic ring is (much) too much
In defense and to explain why there is ever 2 stars, let me say that the cartridge at least very well served its purpose. The filter effect is great and I have, for example. When sanding a much better air.
I myself will however change to a single extraction. I let myself reluctantly abzocken (Price and exclusion of an independent cleaning by lousy choice of materials).
