The LifeStraw Peak Personal Straw is a pocket-size hollow-fiber filter you drink through directly from lakes, rivers and streams, or screw onto a standard 28 mm bottle or gravity hose. Its membrane filter removes bacteria, parasites, microplastics, silt and sand, and is rated for up to 4,000 liters (1,000 gallons) with no shelf life limit. It is lighter and more packable than pump filters and gravity systems, though it has no virus protection and no reservoir of its own. Reviewers rate it as a reliable, low-effort backup for hiking, travel and emergency kits.

Owners and reviewers describe the Peak Straw as a dependable, featherweight filter that works well for sipping from streams and topping up bottles on the trail. Most praise its flow and packability; complaints center on the sucking effort and slowing flow in silty water.
The LifeStraw Peak Personal Straw is a portable straw-style water filter. You can drink directly from lakes, rivers, and streams, or fill a container and drink through the straw. It protects against bacteria, parasites, microplastics, silt, sand, and cloudiness.
It uses a membrane microfilter built to reduce clogging from sand and silt, which helps keep the flow rate up. The filter lasts up to 4,000 L (1,000 gallons) of water, which is enough drinking water for one person for over 5 years. The straw is lightweight and durable, and it has an unlimited shelf life, so it can sit unused in an emergency go-bag.
The straw attaches to some single-use standard plastic bottles with a 28mm thread. It also attaches to standard gravity hoses using its removable threaded bottom cap.
