How does your ideal filter look – and what does it have to do?

Open plastic ring filters for simple installation.

The clip filter is an open ring filter whose main advantage lies in the simple installation. The expanding movement is performed in the standard version by means of a pivot section. The FLEXi-Clip is a further development of the clip filter. With the FLEXi-Clip the bending forces are spread over several pivot points. This creates optimally installable ring filters characterised in particular by their sturdiness and flexibility.
