iSpring RCD100: what it removes and what it costs

Model: RCD100 countertop RO with instant hot and UV; filters FPC100, MCD100, FCB100 (+ FNF100 rinseable mesh)

The iSpring RCD100 has no certifier listing for any of the contaminants we track. iSpring also claims PFAS, lead, chlorine and fluoride from lab tests that are not certification. For 2 people drinking and cooking with it, replacement filters cost about $116 a year, and it sends about 82 gallons a year to the drain.

These costs assume 2 people and drinking and cooking water (0.28 gallons per person a day, EPA's average adult intake). Yours will differ.

What the iSpring RCD100 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 iSpring cites a lab report but no certifier lists the claim. See certified vs. tested.

Not verified, either way (no certification or brand claim): Chloramine, Arsenic, Chromium 6, Mercury, Microplastics, Cysts, VOCs, 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, plus the water sent to the drain at an average water and sewer price. Water use: drinking and cooking water (0.28 gallons per person a day, EPA's average adult intake).

Rated production is 100 gallons a day; 2 people need about 0.56 — well within it. Colder water and lower pressure reduce actual output.
