What contaminants does this filter remove?

The hollow-fiber membrane removes bacteria and protozoa, including common waterborne pathogens like E. coli, Giardia, and Cryptosporidium. It does not remove viruses, dissolved chemicals, pesticides, or heavy metals. It is designed for backcountry water sources in North America where bacteria and protozoa are the primary threats.

How do I use a squeeze filter?

Fill a compatible collapsible pouch or bottle with water from a stream or lake, screw the filter onto the threaded opening, and squeeze the pouch to push water through the filter membrane. You can drink directly from the filter spout or dispense filtered water into another container. When flow rate slows, backflush the filter according to the manufacturer's instructions.

Does this work with standard water bottles?

The filter threads onto standard-size openings found on many disposable water bottles, collapsible hydration pouches, and some reusable bottles. Check that your bottle or pouch has compatible threading before heading out.

How do I maintain the filter between trips?

After each trip, backflush the filter to clear the membrane, then let it air-dry completely before storing. Never let the filter freeze when wet, as ice expansion can rupture the hollow fibers and ruin filtration. Store it in a dry place until your next outing.

Ultralight squeeze filter for backcountry water

Most backcountry water filters either add weight you notice or slow you down at every refill. Pump filters mean extra ounces and moving parts; gravity systems mean waiting. A squeeze filter puts safe water in your hand as fast as you can compress the pouch, with nothing heavier than the filter cartridge itself to carry.

This design matters when you're counting grams or when you stop for water six times in an afternoon. The difference is ten seconds at a stream instead of five minutes setting up a gravity bag, and a pack that weighs what you planned instead of what you compromised on. For anyone moving fast or light in places where the water runs clear enough to see but not clean enough to trust, this is the tool that makes both possible.

The details

This squeeze-style water filter is built for backpackers and hikers who need safe drinking water without carrying liters from trailhead to camp. Fill a compatible pouch or bottle from a stream or lake, thread the filter onto the opening, and squeeze to drink or fill a clean container. The hollow-fiber membrane removes bacteria and protozoa that cause waterborne illness.

The micro designation refers to the compact size and light weight—designed to disappear in a pack rather than dominate a side pocket. The filter attaches to standard threaded water bottles and pouches, letting you drink directly or dispense into a hydration reservoir or cooking pot. No pumping, no waiting for tablets, no backup batteries.

Because it relies on mechanical filtration through a physical membrane, the filter requires backflushing after extended use to maintain flow rate. It does not remove viruses, dissolved chemicals, or heavy metals. Suitable for North American backcountry water sources where bacteria and protozoa are the primary concern. Store it dry between trips to prevent membrane damage from freezing.
