Jim A.wrote a review of Katadyn Gravity Camp 6L Water Filter on August 11, 2018
Familiarity: I've used it several times
I was intrigued by the concept of a gravity fed filter after years of pumping. And had to give it a try. This product worked great the first day. Beginning the second day, the flow drastically dropped to a trickle, then to a slow drip. The sponge provided to clean the filter was ineffective. Good thing we packed a pump filter as a backup or we would have been out of water. After the trip, I tried to clean the filter at home to no avail.
