Defender® Regenerative Media Filters

Defender®  Water Quality

 

(visit www.defenderfilter.com 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.
