These three brands solve different problems. Here is when a countertop gravity system, a personal filter or an under-sink system fits.
Key takeaways
- Berkey, LifeStraw and Frizzlife solve different problems.
- Gravity filters work without power or pressure. Under-sink ones need pressure.
- Many households sensibly own one home filter and one personal filter.
Honest note: we have not tested these filters. We compare the type of product each brand is best known for and send you to the maker for current specs, certifications and prices.

How to pick
- No running water for days: a gravity system, plus stored water.
- One person on the move: a straw or bottle filter.
- Better daily water now, helpful in an outage that keeps taps running: an under-sink system.
Many households sensibly own two: a gravity or pump filter for home and a personal filter for each go-bag.
