Diatomaceous Earth (D.E.)
D.E. is a natural substance that captures dust, dirt and debris as small as 5 microns. A D.E. filter system removes body oils, suntan lotions, pollens, dust, and even some bacteria, making your swimming pool a healthier environment.
D.E. Filter systems cut energy costs by using lower pump pressure and speeds. If properly taken care of and rinsed regularly, they can significantly reduce water use. In addition to cost savings, lower pump pressure can help prolong the life of your pool pump!
A D.E. Filter maximizes the useful filtration area. A larger filtration area means longer periods between each cleaning, saving you time on pool maintenance and giving you more time to relax and enjoy your pool.
