Good is relative. Viruses and chemicals is not good for 100,000 litres.
It's good that they recognise the tendency to clog by supplying with a backslash kit. I read sawyer durability and clogging are two negative aspects of that product.
I used a drink safe filter inline. Squeezing the top bladder to fill the clean water bladder was surprisingly harder than a Kathryn pump filter I tried. That was an earlier model that didn't have the high flow rates they do today.
Saw a new to me player in the pump filter market. It has a modular filter to allow you to tailor to the turbidity or not of source water. Just add 1, 2 or 3 dot filter sections can be used as a pump, straw, inline and gravity filter. Cheaper than Kathryn too. Tempted.
