Bring commercial-grade water filtration home with the Pentair Everpure H-300-NXT replacement cartridge (Item #EV927441). Built on the trusted technology of the top-selling H-300, the H-300-NXT was the first cartridge of its kind certified by NSF to NSF/ANSI Standard 401 for the reduction of emerging contaminants — including pharmaceuticals, over-the-counter medications, herbicides, pesticides, and manufacturing chemicals like BPA.

The H-300-NXT uses Everpure's exclusive precoat filtration technology, combining Micro-Pure media with a unique pleated filter membrane that's 30% larger than the standard H-300 filter for enhanced contaminant reduction and extended service life. It effectively reduces lead below the Federal Action Level, chlorine taste and odor, chloramines, VOCs, and cysts such as Cryptosporidium and Giardia (NSF/ANSI Standard 53 certified), while KDF media helps inhibit scale buildup that can damage water-using appliances.

Rated for 300 gallons of capacity at a controlled 0.5 GPM flow rate, the H-300-NXT should be replaced 1–2 times per year for continued peak performance. Housed in a commercial-grade metal canister that resists splitting or bursting, it's made in the USA and quick-change designed for fast, simple cartridge replacement.
