Sawyer SP140 Personal Water Bottle Filter, 34-Ounce, Blue

Overview

Meet the Sawyer SP140 Personal Water Bottle Filter, a featherweight companion for outdoor days. Weighing about 5.5 ounces, this durable 34-ounce bottle is designed for hikers, campers, ultralight travelers, and emergency prep kits. The included inline filter converts a simple bottle into a practical filtration system for fresh tasting water on demand.

What makes this stand out

Key capabilities come from a 0.1 micron absolute hollow fiber membrane that targets a broad range of common waterborne contaminants. Independent testing confirms the unit reduces 99.99999 percent of bacteria such as Salmonella, Cholera, and E. coli, and 99.9999 percent of protozoa such as Giardia and Cryptosporidium. It also removes 100 percent of microplastics according to the model specifications. The bottle is BPA free and lightweight, and the inline filter provides a high flow rate so you can hydrate quickly on the trail.

Practical benefits and use cases

Whether you are hiking a rugged ridge, backpacking remote trails, or stocking a ready kit, SP140 is built to be field maintainable. The cap fits 63 mm wide mouth bottles, and the system can be used directly in the bottle, or inline with a hydration pack tubing for hands free sipping. The newest model no longer includes extra straws, simplifying the setup, while the backwash syringe makes maintenance straightforward in the field.

• High flow filtration supports quick hydration on the move.
• Lightweight build makes it easy to carry for long days outdoors.
• Compact design pairs with hydration packs for on the go filtration.
• Inline compatibility enables multiple use scenarios including emergency prep.

How to use and care

Fill the bottle from a river, lake, or faucet, screw on the cap, and drink directly or via the built in spout. For ongoing use, backwash the filter with the included syringe and rinse after heavy use. Store in a cool place when not in use.

• Fill, screw, and drink for fast access to clean water.
