Culligan Hydro-Cleer filters use diatomaceous earth (D.E) filtration to provide best in class swimming pool filtration down to levels of 1 micron.
Diatomaceous earth is a white powder, which comes from the silica cell walls of microscopic algae.
The Hydro-cleer units utilise the Culligan exclusive “self-cleaning elements” technology that helps you reduce water usage and save costs.
