How a gravity filter works
- Pour water into the top chamber. Tap water, or stored water in an outage.
- Gravity pulls it through the filter. No pump, no power, no installation.
- Filtered water collects below. Open the spigot whenever you need a glass.
Because it needs no electricity, it keeps working during power outages.
