The HP designation means the resin is \u003cstrong\u003eWQA Gold Seal certified for potable water\u003c\/strong\u003e, so the media itself has been third-party verified safe for drinking water service. It removes \u003cstrong\u003ePFOA, PFOS, and a wide range of additional PFAS species\u003c\/strong\u003e, plus nitrate, perchlorate, iodide, and pertechnetate.\u003c\/p\u003e\n\n\u003cp\u003eThis is the \u003cstrong\u003eexact media inside our \u003ca href=\"\/products\/pfas-removal-system\"\u003ePFAS Removal System\u003c\/a\u003e\u003c\/strong\u003e. The 1 cubic foot bag is for two buyers: owners rebedding a PFAS ion exchange tank, and DIY builders loading a custom PFAS system who want certified, PFAS-selective resin rather than generic bulk media.

Its selectivity binds PFAS so strongly that a brine regeneration cannot strip it back off, which is exactly what makes it effective in service. When the bed reaches capacity, the spent resin comes out and fresh resin goes in. That is the standard approach for residential PFAS ion exchange. \u003cstrong\u003eReplacement interval depends on your PFAS level and your water chemistry\u003c\/strong\u003e: higher TOC and sulfate compete for capacity and shorten bed life, so we estimate intervals from your actual water test, not a flat gallon claim.\u003c\/p\u003e\n\n\u003ch3\u003eSizing and Loading\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eA 12\" x 48\" tank holds ~1.5 cubic feet\u003c\/strong\u003e - a full rebed of our PFAS Removal System takes two bags, with media left over.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum bed depth 24 inches\u003c\/strong\u003e - shallower beds short-circuit and break through early.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService flow 1-4 gpm per cubic foot\u003c\/strong\u003e (8-32 bed volumes per hour) - slower flow means more contact time and better PFAS capture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating range\u003c\/strong\u003e - pH 4-10, temperature limit 250 F, capacity 0.8 meq\/mL, ship weight 40-42 lbs per cubic foot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-filtration required\u003c\/strong\u003e - sediment, iron, and manganese must be handled upstream or they foul the bed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTest First, Then Size\u003c\/h3\u003e\n\n\u003cp\u003ePFAS has no taste, color, or smell, so both the initial sizing and the annual performance check come from a lab test.
