Questions & Answers
How fast is ultralight in real use?
Instant flow is higher with pumps; gravity wins for unattended batches. Squeeze/inline depends on bottle pressure and water clarity.
What maintenance keeps a ultralight performing well?
Pretreat silty water, backflush after dirty sources, and sanitize before long storage. Protect wet elements from freezing.
How do I size capacity with ultralight?
Plan for 2–4 liters per person per day. For group cooking, gravity is efficient; for solo travel, a compact setup saves weight.
Will ultralight cope with shallow or murky sources?
Yes with technique: scoop from trickles with a cup, let sediment settle, and strain through cloth before filtering to preserve flow.
Do I need a backup treatment with ultralight?
Carry tablets or a spare element on longer trips. Redundancy covers breakage, unexpected contamination, or freezing damage.
