What the Clearly Filtered 3-Stage Under the Sink 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 Clearly Filtered cites a lab report but no certifier lists the claim. See certified vs. tested.
Not verified, either way (no certification or brand claim): Chloramine, Nitrate, Chromium 6, Mercury, 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).
| Household | Gallons a year | Filters a year | Total a year | Per gallon |
|---|---|---|---|---|
| 1 person | 102 | $455 | $455 | 445¢ |
| 2 people | 204 | $455 | $455 | 223¢ |
| 4 people | 409 | $455 | $455 | 111¢ |
Per-gallon costs in the table are for real use, so they also count any filter replaced at its month limit before it reaches its gallon rating. At rated filter life alone, filters cost 23¢ a gallon (the figure at the top of this page).
