Common misconceptions
What is the real cost?
Per-year cost comparison
Sawyer Mini ($28.99) vs Katadyn BeFree ($42.95) vs LifeStraw Personal ($14.99) -- the gap compounds over years. Drag the slider to match your real usage.
At 3 years: LifeStraw Personal costs $2.00/year less than Sawyer Mini -- about half a cent per day for a brighter beam and a 30-hour runtime.
When to act
Use Sawyer Mini for 3 real night outings first
If it already solves your problem, keep it. The $1.00-$6.00 switching delta is rarely worth it for hypothetical use cases.
Identify the actual pain point
Is it rating, price, runtime, or charging? If rating: Katadyn BeFree wins. If price or runtime: LifeStraw Personal wins. Otherwise keep Sawyer Mini.
Move only if the pain point is documented
Read 10 negative reviews of your target switch. If your pain point appears in 3+ reviews, the switch is justified.
Keep Sawyer Mini as backup until the new water filter is proven
Do not sell Sawyer Mini until Katadyn BeFree or LifeStraw Personal has been your primary water filter for 30 days.
