| Household | Gallons a year | Filters a year | Total a year | Per gallon |
|---|---|---|---|---|
| 1 person | 102 | $148 | $148 | 145¢ |

| 4 people | 409 | $148 | $148 | 36¢ |
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 15¢ a gallon (the figure at the top of this page).
