20" Commercial Filter Pack

20" Commercial Replacement Filter Pack This is the pre-filter pack for our Pump Driven Commercial RO systems. We love the 2.5 GPM flow rate with this specific filter array. Our array of high flow rate filters directly results in higher purity water as your RO membranes receive more line pressure than lower flow rate or lower micron size filters. (less pressure drop when filters get exhausted). We ask you to change your pre-filters every 1500 gallons of pure RO water. The 3 prefilter stages are as follows: (Stage 1) 20"  Polypro (PP) Sediment [ 10 Micron ]. (Stage 2) 20" Coconut Activated Carbon block [ 10 Micron ] OR 20" Catalytic Carbon. (Stage 3) 20" Coconut Activated Carbon Block [ 5 Micron ] For use on all 20" RO systems, where you have 3 cartridge housings across the bottom. Fits all standard 20" housing units. Dimensions and Weight: Height : Standard 20 " x 2.5 "  Weight :  8 pounds  Illustrations/Diagrams/Instructions: How to Change Filters
