How much will you save
with a filtration system?

Every drinking water system we install replaces the garrafón (10-20L bottle) run entirely — water straight from your own tap, through a membrane you can inspect and maintain yourself. Pick your household size, a timeframe, and a system to see what that's actually worth.

Your household

Each person is counted at ~3 liters per day — the commonly recommended ~2 liters of drinking water, plus cooking and coffee.
Compared using the installed price plus maintenance-plan pricing over your timeframe.

These figures use today's prices and don't account for inflation. Assumes ~3 liters per person per day (drinking plus cooking) and $38 MXN per 10 L single-use garrafón (typical OXXO shelf price); system costs use our installed price plus maintenance-plan rates. Actual prices and habits vary.
