To prevent lime and other particles from being flushed out of a dosing float and into the pool, a filter mat can be inserted. To prevent it from slipping in the float, it can be fixed with this Filterholder.

I use a filter mat, which is originally designed for use in the skimmer basket. You can buy the suitable filter mat in a pool store. The dosing float that fits the Filterholder is from the Austrian manufacturer BWT.


You can buy the “Skimmer filter” at the german pool store PoolTotal:

• PureFlow Skimmerfilter für Standard Miniskimmer Korb

The dosing float is available directly from the BWT online store:

• AQA marin Dosierschwimmer
