Ultralight backup vs. daily driver — where straw filters fit.
Full guide coming soon.
Questions & Answers
When does a straw filter make sense?
They’re perfect as a backup or for quick sips on day hikes. Weight is minimal, but you must drink directly from the source or a container — not ideal for cooking or groups.
What are the limitations?
Most straw filters don’t handle viruses and don’t store treated water. Flow can be restricted, and they’re awkward in shallow or silty sources without a cup or bottle.
How do I keep flow high?
Avoid silty water when possible and blow back through the straw to clear fibers after use. Let sediment settle before drinking to reduce clogging.
Can I use a straw inline with a reservoir?
Some models can be plumbed inline, but check manufacturer guidance. Inline use increases resistance; a dedicated inline/squeeze filter usually performs better.
What about freezing?
If a hollow‑fiber element freezes when wet it can be compromised. Keep the filter warm overnight or carry it in a pocket in sub‑freezing temps.
