How often should I replace the filter in my Doulton filter system?

We recommend replacing your filter every 6 months. If you notice a drop in water pressure or a change in taste, it may be time to replace the filter. You can try cleaning the filter first, following our guidelines if you notice any changes earlier.

What systems is the Biotect Ultra Filter compatible with?

The Biotect Ultra filter is compatible with all Doulton under sink and tap-mounted countertop systems. They are designed for use with any system that has an M12 fitting. For use with other brand check with manufacturer directly for compatibility.
