Yes. Our PFAS Removal System (the 12" x 48" tank) ships loaded with this exact resin, ResinTech SIR-110-HP. This bag exists so owners of that system can rebed it when the resin reaches capacity, and so DIY builders can load their own tank with the same WQA Gold Seal certified media instead of guessing at bulk resin quality.

A 12" x 48" tank holds approximately 1.5 cubic feet of resin, so a full rebed takes two of these 1 cubic foot bags with media left over. A 10" x 44" tank takes about 1 cubic foot (one bag) and a 13" x 54" tank takes about 2 cubic feet (two bags). Keep a minimum bed depth of 24 inches in whatever tank you use. If you are not sure what your tank holds, call or text us the model or the diameter and height and we will tell you.

No, and this is the most important thing to understand before buying. SIR-110-HP is single-use for PFAS duty. The resin's selectivity means it binds PFAS so strongly that a salt brine regeneration cannot strip it back off the way hardness is stripped off softener resin. When the bed reaches capacity, the spent resin is removed and replaced with fresh resin. That is the standard approach for residential PFAS ion exchange, not a shortcoming of this particular product.

It depends on three things: your PFAS concentration, how much water your household uses, and your water chemistry. Higher PFAS levels exhaust the bed faster. High TOC (total organic carbon) and high sulfate both compete with PFAS for exchange sites and shorten bed life, sometimes significantly. Because of that, we do not quote a flat gallon number that ignores your water. Send us your PFAS test and a standard water test and we will estimate a realistic replacement interval for your situation. Then verify with an annual PFAS test on the treated water, because breakthrough has no taste, color, or smell.

It is a selective strong base anion resin that removes PFAS (PFOA, PFOS, and a wide range of other PFAS species), nitrate, perchlorate, iodide, and pertechnetate. The HP designation means the lot is WQA Gold Seal certified for potable water use. Note that if your water has meaningful nitrate or sulfate, those ions consume capacity too, which is part of why bed life varies with water chemistry.

Size for 1 to 4 gallons per minute per cubic foot of resin, which is 8 to 32 bed volumes per hour. Slower flow within that range gives more contact time and better PFAS capture. Keep at least 24 inches of bed depth. A 1.5 cubic foot bed in a 12" x 48" tank comfortably supports whole-house service flow for a typical home, which is exactly how our PFAS Removal System is configured.

Yes. Sediment, iron, and manganese will foul the bed and cut its PFAS capacity short, so they must be handled upstream. At minimum run a sediment pre-filter; if your water test shows iron or manganese, treat those with a dedicated system first. On well water we usually recommend the full treatment train review. Send us your water test and we will lay out the right order.

Spent residential PFAS resin is generally disposed of as ordinary solid waste: bag it and put it in the trash, following any local guidance. Never rinse spent resin down a drain or spread it outdoors, because the PFAS it captured stays bound to the beads. If your municipality has specific PFAS disposal rules, those take precedence. Call us if you want help checking.
