What the APEC ROTL-A1000 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 APEC 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, Nitrate, 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).
| Household | Gallons a year | Filters a year | Drain water | Total a year | Per gallon |
|---|---|---|---|---|---|
| 1 person | 102 | $192 | 51 gal ($1) | $193 | 189¢ |
| 2 people | 204 | $192 | 102 gal ($2) | $194 | 95¢ |
| 4 people | 409 | $192 | 204 gal ($4) | $196 | 48¢ |
Rated production is 1000 gallons a day; 2 people need about 0.56 — well within it. Colder water and lower pressure reduce actual output.
