SAWYER 1 GALLON GRAVITY SYSTEM SP160 / SAWYER 1 GALLON GRAVITY SYSTEM [SAWYER]

The large-capacity pouch and gravity system make it easy to obtain large amounts of purified water.

A tough water filter that removes 99.99999% of harmful bacteria and parasites such as echinococcus that lurk in water.
The Sawyer is a portable water filter boasting the world's highest level of purification performance. It eliminates the need to carry large amounts of water and allows you to drink water immediately from rivers, lakes, and other water sources scattered throughout the area, making it a popular choice for hikers and long-distance hikers. By filtering the water through its ultra-high-density filter, it removes 99.99999% of harmful bacteria, aquatic microorganisms, and parasites like echinococcus from the water, turning it into potable water.
*This filter cannot remove dissolved solids including calcium, magnesium, and heavy metals dissolved in water, radioactive substances, industrial wastewater, water that may contain dissolved chemicals, or viruses that are even smaller than bacteria.

0.1-micron compatible water purification filter <br>The filter body contains a U-shaped hollow fiber membrane, which filters water through countless uniform 0.1-micron holes. This allows us to create a high-performance, compact, lightweight, and durable filter. 0.1 microns is equivalent to 0.0001 mm in millimeters, and does not allow common bacteria, which are said to be 0.5 to 1 micron in size, to pass through.

Gravity system for comfortable, speedy water purification <br>The gravity system uses gravity to automatically purify water. The weight of the water adds momentum as it passes through the thin tube, allowing you to obtain purified water quickly and effortlessly. Using the included 1-gallon pouch, you can hang it up and purify large amounts of water at once. Another attractive feature is that it doesn't get in the way of your hands. If you set it up at night when camping, you can have purified water ready in the morning, which is very convenient.
*If you lower the pouch from top to bottom while leaving water on the outside, the unpurified water may fall directly into a water bottle without passing through the filter, so be sure to wipe off any moisture before hanging it.

It can be used for a variety of purposes other than gravity .<br>Its flexible design and options allow for a wide range of uses.
① Can be directly attached to commercially available plastic bottles. Even in situations where pouches are not available, you can purify water using easily available plastic bottles.
② Can be attached to small pouches. Small pouches (sold separately) can be attached to both sides of the filter, allowing one to be used for dirty water and the other for purified water.
③ By connecting the included straw, you can insert the straw into a cup or bottle from which you can drink directly, or you can drink purified water directly from a water source.
4. Can also connect to hydration systems made by other companies. Compatible with hydration, which is essential for mountain climbing and trekking.
If the screw part is compatible with connections, it can be used for even more purposes. Try to find a way to use it that suits you.
*Please note that depending on the PET bottle, if the screw shape is not standard, it may not be possible to connect it.

Highly acclaimed worldwide <br>Sawyer's superior cleaning capabilities are recognized worldwide, and it is used in over 80 countries and regions around the world where clean water is difficult to obtain, such as disaster-stricken areas and refugee camps. Sawyer works with NPOs and NGOs to provide its products. It works every day to supply people with clean water, and has made great strides in the areas where it is provided, including a significant reduction in diarrhea and disease. In addition, a portion of sales is used for international aid activities.
After the Nepal earthquake in 2015, UPI provided squeeze filters to the affected areas through a professor at Kwansei Gakuin University.

Water purifiers are also gaining attention as disaster prevention items . In Japan, a country prone to disasters, disaster preparedness is something that must always be kept in mind, and the compact Sawyer is gaining attention as a disaster prevention item not only for its high functionality, but also for its reduced water storage volume and portability. Even when lifelines are cut off, using a portable water purifier makes it possible to secure safer drinking water from nearby water sources.
*When collecting water, you can reduce the strain on the filter by collecting as clean water as possible, such as choosing water from as upstream as possible in the case of a river.

Exceptional fiber strength allows for filtration of 380,000 liters of water. Even more economical <br>Sawyer's hollow fiber has thick walls for each fiber, and independent research has proven that it is over 75% stronger than other major brands. This makes it durable enough to withstand backflushing (maintenance cleaning), eliminating the need for filter replacement and allowing a single filter to purify 380,000 liters of water. Assuming 10 liters of water purified per day, it can be used for over 100 years, making it extremely economical.
While other companies typically use random testing or batch testing, which involves selecting and testing a few items from a large number of items, Sawyer has manufactured all of its products in its own factory in Florida since its founding in 1984, and conducts product testing on each item three times to ensure the safety of its products.

Backflush (maintenance cleaning)
After use, you can clean the filter by using the included cleaning syringe (without needle) to inject clean water backwards to remove impurities. Backflushing restores approximately 98% of the filter's functionality, allowing you to purify water as before.
*If you feel that the function is not returning, we recommend repeating the backflush several times.
