REI

Think of water filtration in a whole new way with the quick and convenient gravity-powered Sawyer water treatment system.

  • Utilizing a hollow fiber membrane filter, the Sawyer system yields 4 liters of potable water in as little as 3 min.
  • Simply fill the included reservoir with unfiltered water, attach the filter and hoses and let gravity do the rest to fill your own hydration reservoir or water bottle
  • Filter physically removes particles, protozoa, and bacteria down to 0.1 micron in size, including giardia, salmonella and cryptosporidia
  • All Sawyer water filters exceed Environmental Protection Agency (EPA) recommendations for removal rates
  • Filter is fully field maintainable to ensure a fast flow of water; system includes a faucet adapter for thorough back washing from a household faucet
  • Setup is simple and the system packs easily, weighing in at only 12 oz.
  • This Sawyer water filter comes with a Million Gallon Guarantee, essentially eliminating the need to ever have to replace the filter cartridge
  • System includes a 4 liter reservoir, hollow fiber filter, faucet adapter, filter tube, quick-release hose adapter, Nite Ize S-Biner hanging loop and instructions for use
  • Please note: Take care not to let your filter freeze as this could damage the filter housing or the fibers themselves

Surprisingly good

Rating:****
My husband and I just spent a month in the high Sierra's and wanted a water "bag" for camp use. I did a lot of shopping around and finally decided to try the Sawyer system. We loved this system. While we used a standard pump filter during the day while hiking, we used the Sawyer extensively while in camp. We just filled the 4 liter bag when we set up camp each day (this was not a base camp situation... we moved camp every night) and had plenty of water for cooking, cleaning etc. We could also fill our Platy-bottles for the next day of hiking. It is EXTREMELY easy to use and required NO maintenance the entire time. I figured this system would be convenient but I did not expect to be so pleased with the ease of this system. We were so glad we carried the Sawyer system (despite the extra weight) and will do so again on furture adventures.

High quality filtration system

I came in to buy the Katadyn Basecamp, but my local store was out of stock, so I took a chance on the Sawyer. Out of the box I was pleased with the quality of the valve and connection components. Sawyer conjured recollections of "economical" camping gear so I was pleasantly surprised. I just returned from a 2 day hunting scout trip and am very pleased with its performance: very easy to use (first use was in the dark) and the flow is very fast. One bonus over the Katadyn is that the bladder is completely sealed and I could transport water in my pack to a dry camp. The only con is that the bladder could be a little larger.

awesome piece of equipment!!!!!

I HIGHLY RECOMMEND THIS to anyone who is looking for a water filtration system with low maintenance issues.

I used this system on a 3 day backcountry trip and yes had to fill it up quite frequency, but never had to back flush til i got home, and i used it to support 3 people!! very happy with this product!

IMPORTANT: however, there were a few problems... first off its a little leaky, which is mostly due to condensation. secondly, if using it in the winter make should you don't leave any water in the filter or the water will freeze, which will result in having to boil the filter in hot water before use.

Functional

Used at main camp for 8 days in the Yukon. Only issue I had was it leaked. Easy to use and can filter a lot of water in a short period of time. I prefer this gravity filtration over the pump types any day. The chance of this breaking is very low and I could deal with the small leak. I would highly recommend.

Reservoir cap broke in the first 24 hours. Still functioned, but took finesse to filter water. Biggest problem was I sent two emails to Sawyer for a new cap, and there was never a reply.
