In addition to exceptional filtration, Pentair SMBW 4000 Series D.E. filters feature sheet molded fiberglass tanks and Noryl rotary backwash valves for long life, dependable performance and easy maintenance.

SMBW 4000 Series D.E. filters provide optimum filtration efficiency, easy maintenance, and longer runs between cleanings. Their extraordinary dirt-holding capacity and easy cleanability make them the perfect choice for every pool.


Diatomaceous Earth (D.E.)

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.
Energy Efficient

Energy Efficient

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!
Low Maintenance

Low Maintenance

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.
