What the Pentair Everpure H-300-NXT removes

"Certified" means a certifier (NSF, WQA, IAPMO or CSA) lists this exact product for that reduction claim; the listing is linked. "Brand test only" means Pentair Everpure cites a lab report but no certifier lists the claim. See certified vs. tested.

Contaminant	Status	Evidence
Lead	Certified	NSF listing, NSF/ANSI 53 ("Lead")
Chlorine	Certified	NSF listing, NSF/ANSI 42 ("Chlorine")
Microplastics	Certified	NSF listing, NSF/ANSI 401 ("Microplastics")
Cysts	Certified	NSF listing, NSF/ANSI 53 ("Cyst")

Not verified, either way (no certification or brand claim): PFAS, Chloramine, Fluoride, Arsenic, Nitrate, Chromium 6, Mercury, VOCs, TDS, Bacteria and viruses, Iron, Copper, Uranium, 1,4-dioxane.

What it costs to run

Yearly cost = replacements per year × filter price, for each filter it uses; a filter is replaced at its gallon rating or its month limit, whichever comes first. Water use: drinking and cooking water (0.28 gallons per person a day, EPA's average adult intake).
