Connections and fit

The supplier describes a silicone adapter for bottle openings approximately 1.10–1.18 inches (28–30 mm) across and compatible tapered faucet outlets approximately 0.51–0.79 inch (13–20 mm) across. These dimensions do not establish universal thread or faucet compatibility; confirm your connection and the supplied adapter before use.

Verify performance before relying on this filter

The supplier advertises a 0.01-micron membrane and a service life of approximately 1,057 US gallons (4,000 L), but no supporting test report or independently verified performance certification is provided in the listing. Actual service life and replacement criteria require manufacturer confirmation. Pouch capacity, filter dimensions, and weight are not specified.

Do not assume this filter makes untreated water safe to drink or reliably removes bacteria, viruses, parasites, dissolved salts, heavy metals, or chemical contaminants. It is not identified as a reverse-osmosis system. Do not use it to treat seawater, urine, pesticide-contaminated water, or other chemically polluted sources.

Obtain model-specific test documentation, source-water restrictions, and complete manufacturer instructions before relying on it for drinking water. Clear appearance or improved taste does not establish water safety. Carry a known-safe drinking-water supply for your outing.

The selected shipping-origin option is China. Colors may vary slightly between screens.
