About Water Filtration & Purification

Water Filtration & Purification — Make It Drinkable

Most water sources require treatment before consumption. SRO's Water Filtration & Purification collection covers hollow-fiber filters, gravity systems, chemical treatments, and emergency straws — the specific mechanical and chemical solutions for making water drinkable.

Filtration types

Hollow-fiber (Sawyer) — 0.1 micron, removes bacteria and protozoa, 100,000+ gallon lifespan. Press-purifier (GRAYL) — handles bacteria, viruses, and chemicals via integrated filter cartridge. Pump and gravity (Katadyn Swiss-engineered) — scales to expedition flow rates. Activated carbon — addresses taste and chemical contamination. See the broader Water & Hydration collection for cross-category options.

Match the filter to the water

Backcountry streams need bacteria and protozoa removal. Hotel-tap and well water need viral protection too. International travel may need the full chemical/viral spectrum. Match the filter to your dirtiest realistic source — overspecifying is fine, underspecifying isn't.

Pair with Chemical Treatments (Aquatabs backup), Water Bottles & Storage, and Emergency Foods.

Starting point for most kits: one Sawyer Mini for filtration and one pack of Aquatabs for chemical backup. Two methods, two failure points covered.
