Step 1
Decide what level of protection you want. At the very least, the filter should be fine enough to remove Giardia cysts; fancier filters called purifiers also remove viruses.
-
Step 2
Check the pumping rate: 1 liter per minute is reasonably fast.
-
Step 3
See how often you'll have to replace the filter in the pump, and how much replacement filters cost. If you plan to use your pump quite a bit it could be an important factor.
-
Step 4
Compare several filters to find the best combination of these features.
