Defender® Regenerative Media Filters

Defender®  Water Quality


(visit for more information)

The Defender® Regenerative Media Filters provide exceptional water quality by removing particles down to 1 micron in size when using approved perlite filter media.  


By removing paricles down to 1 micron the filter cycles are dramatically extended and UV transmittance is greatly improved.  


The Defender® filter is especially effective on pools with heavy bather loads because of the increased filter area and dirt holding capacity for both indoor and outdoor applications.




Findings from a recent study by the University of North Carolina on cryptosporidium and particle removal from swimming pool water indicate:


• Precoat Filtration with both DE and perlite outperformed cartridge and sand filtration by a wide margin.


• Single pass testing resulted in crypto removal of 99.9% using perlite media.


• When testing 1-micron microsphere removal, perlite performed at 56.5% versus 20.2% for sand.
