What's the best water filtration system for emergencies?

The best emergency system filters without power and gives you cleaner, better-tasting water. Our gravity-fed designs target 200+ contaminants, and the Patriot Pure® Ultimate Water Filtration System carries NSF 42, 53 and 401 certifications. Sizes run from a countertop unit for the whole household down to a straw that fits a jacket pocket. Pair whichever you choose with stored water from our long-term water storage page so you have a reserve to filter from.

  • Cleaner, better-tasting water: Filtration that targets 200+ contaminants, including lead and the chlorine taste most tap water carries.
  • No power needed: Gravity-fed designs that work through an outage with no cords and no pump to fail mid-storm.
  • Sized for the household: Countertop units for daily drinking water, plus compact filters for the car or a pack you keep by the door.
  • U.S.-based support: Our American care team and money-back guarantee, with replacement filters always in stock.

Reduction rates are certified to 200 gallons by an ANSI-certified independent laboratory using NSF standards (up to 800 gallons for some contaminants). Results will vary based on the specific contaminant, water quality & source, and usage conditions. Do not use water from unsafe or unknown sources. Changes in flow rate, taste, or smell may indicate that a filter needs replaced.
