The LifeStraw Go Series is designed for safer, tastier water during travel and everyday use. The bottle is made from stainless steel, BPA-free, with double-wall insulation to maintain water temperature.

It features a two-stage filter to remove contaminants and harmful substances, allowing you to fill from various sources. The filter improves the taste of water and protects against bacteria, parasites, microplastics, chlorine, sediment, sand, and cloudiness.

• First Stage: The activated carbon filter reduces chlorine, unpleasant tastes, and chemical compounds. It lasts for approximately 100 liters.
• Second Stage: Creates a filtration membrane that neutralizes 99.9999% of bacteria and 99.9% of protozoa. The filtration lifespan is at least 4,000 liters.

Meets the quality standards of the U.S. Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA). It requires no electricity, batteries, or replacement parts and leaves no aftertaste.

After use, blow air to clean the filter and rinse the bottle. Please read the Instructions for Use carefully.
