I should've listened
I read the reviews that said this clogged right away. I decided to buy it anyway. It worked well when tested at home. Out on the field, it sucked. We were using it to filter water from a faucet (rainfall, a bit murky). The first liter was ok, no go on the 2nd liter. I cleaned filter and tried again, no go. I pumped slower and still didn't work well. It's going back.
