Sawyer 4L Gravity Filtration System

Manufacturer's Description

A time tested favorite, Sawyer’s 0.1 Micron Gravity Filtering System simplifies backcountry hydration needs. This versatile, safe, and highly effective bag system is practically hands free. Just hang the system from a tree or any source off the ground, and gravity does all the work quickly — filtering 2 liters of water in as little as 90 seconds.

Packing Sawyer’s Point ONE filter mechanism (rated to 0.1 micron absolute filtration), the Gravity Filtering System removes 99.99999% of all bacteria, such as salmonella, cholera, leptospirosis and E.coli, and removes 99.9999% of all protozoa (such as giardia and cryptosporidium).

It comes in two sizes (2- and 4-liter) and in two configurations — either a single bag (for filtering into your own container) or a dual-bag package (one for dirty water, one for clean water).

Retailers' Descriptions

Here's what other sites are saying:

Sawyer Camp & Hike Complete 4L System SP184. Simply set up the Sawyer water filtration system and let gravity provide you with 4 liters of fresh clean water in about 3 minutes. Each filter has a lifetime warranty as long as you follow the simple care and use instructions. Follow the helpful hints included in the directions for use. Backwashing is not required often unless you are filtering very turbid water. Backwashing only takes a few seconds. If you are accustomed to a ceramic filter the leaning ratio is approximately 20:1. In other words by the time you first need to clean your hollow-fiber filter you would have neeeded to clean a ceramic filter 20 times. NO REPLACEMENT FILTERS OR CARTRIDGES ARE NECESSARY. We trust you will thoroughly enjoy the ease and extra protection this proven next-generation technology offers you.The Sawyer Water Filters feature a 0.1 Micron Absolute Hollow Fiber Membrane which uses medical technology developed from kidney dialysis. When the water is drawn through the filter it flows through the side walls of the Hollow Fiber tubes. Sediment bacteria protozoa cysts and other contaminants are filtered out exceeding all applicable EPA recommendations. NO CHEMICALS NO WAITING NO PUMPING NO WORRIES
