What the PUR PLUS faucet filter 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 PUR cites a lab report but no certifier lists the claim. See certified vs. tested.
Not verified, either way (no certification or brand claim): Chloramine, Fluoride, Arsenic, Nitrate, Chromium 6, Cysts, 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).
