GreenTech Enviromental PREFILTER KIT PureWash Prefilter System Feature: In order for your PureWash to perform most effectively, water quality issues must be addressed. Installing a pre-filter is recommended to treat mild water quality issues, as unfiltered impurities in the water supply can potentially interact with the oxidizers produced by PureWash thereby hindering your PureWash's performance. Our pre-filter is a 2-stage KDF 55 and Granular Activated Carbon (GAC) filter. This filter covers most water quality issues such as high chlorine content and high iron content. PureWash Prefilter treats mild water quality issues.
