Sawyer Water Filters & Purification Systems

Sawyer makes the hollow-fiber water filters that have become the gold standard for backpackers, missionaries, and emergency responders worldwide. Lightweight, proven across millions of liters, and trusted in remote environments where filter failure isn't an option.

How Sawyer filters work

Hollow-fiber membrane technology pulls bacteria, protozoa, and microplastics out of source water without chemicals or pumping pressure. The Mini and Squeeze formats screw onto standard water bottles or hydration bladders, weigh ounces, and field-clean with a backflush syringe — no replaceable cartridges, no fragile parts.

Use cases

• Backpacking and through-hiking — primary filtration
• Emergency preparedness — long-shelf-life backup
• International travel where tap water isn't safe
• Mission and humanitarian work in remote regions
