A high capacity water filter turns large amounts of creek, rain barrel or suspect tap water into safe drinking water for the whole household, week after week. It keeps your family supplied when the tap stops or turns unsafe at home, and it travels with you if you have to leave for good.
A high capacity water filter turns gallons of questionable water into drinking water for the whole family, day after day. Choose one sized for your household and built to keep working.
- Flow rate: Pick a filter that delivers at least one gallon per person per day without hours of waiting.
- Filter life: Look for elements rated for thousands of gallons, and stock one spare cartridge per filter.
- Pore size: Choose a rating of 0.1 to 0.2 microns to remove bacteria and protozoa, and add a disinfection step where viruses are a concern.
- Silt and clogging: Favor cartridges you can backflush or scrub so muddy water extends the filter's life instead of ending it.
- Portability: Pick a gravity or squeeze design that packs down for a bag and still serves a household at home.
- Freezing: Store used filters above freezing, since ice can crack the membrane without any visible sign.
