Those resins prefer sulfate over nitrate, and that creates a dangerous failure mode: once the resin loads up with sulfate, it can \u003cstrong\u003edump previously captured nitrate back into your water\u003c\/strong\u003e at concentrations higher than what's coming out of the well. SIR-100-HP is engineered with a different functional group that prefers nitrate: there is \u003cstrong\u003eno nitrate dumping, even past the sulfate break\u003c\/strong\u003e. It also removes perchlorate, and the resin itself carries the \u003cstrong\u003eWQA Gold Seal\u003c\/strong\u003e for potable water use.\u003c\/p\u003e\n\n\u003ch3\u003eWhole-House vs Under-Sink RO: The Honest Answer\u003c\/h3\u003e\n\u003cp\u003eA \u003ca href=\"\/products\/pure-75-reverse-osmosis\"\u003ereverse osmosis system\u003c\/a\u003e removes nitrate at a single tap and is a legitimate, lower-cost option when levels are moderate and you only need protected drinking water. A whole-house system treats \u003cstrong\u003eevery tap\u003c\/strong\u003e: cooking water, the bathroom sink where the baby's bottle gets rinsed, the ice maker, all of it. For wells testing over 10 ppm, with an infant or a pregnancy in the house, the gold standard is both: whole-house ion exchange plus RO polishing at the kitchen tap.

Your only routine job is keeping \u003cstrong\u003ewater softener salt\u003c\/strong\u003e in the brine tank: typically $100-200 per year for a family home. There are no cartridges and no single-use media.
