MSR  Guardian Purifier Replacement Cartridge

This is my third replacement filter for my Guardian filter. I have not used this one yet but my guardian has lived up to my expectations. I use it for filling 5 gallon plastic Jerry cans. The speed of filling is great. We've filled from lake Michigan and several creeks and small ponds in mid to northern Wisconsin. My first filter I changed because I took water from the Displanes River just across the southern boarder into Illinois's. Out of pure paranoia from chemicals in this water we did not drink. We thru away the cans we filled and the filter element from the Guardian. I truly wish this system could incorporate a chemical and heavy metals filter of some sort. Otherwise... This is a good system for us.

I have been using this filter for years in far flung places and was super happy with its performance. Then it started leaking water from the side through the crack where the filter element screws into the unit. So instead of getting filtered water through the bottom hole, water squirts out through the sides. No matter who tightly I screw in the filter element, it keeps squirting out the side. Will the purchase of a new filter cartridge solve this problem?

MSR Guardian. I bought it two days ago as a present for my wife for her birthday to use it in her upcoming trip to Nepal. When I tested it, it start leaking. I tried to disassembled it by hand to find out that the end nut was broken. Very disappointing I'm wondering about those military standards...or it is just a trick to by very expensive and not reliable kit. I will ask the shop for return but doubt I will buy again this purifier.

REI IS SELLING THIS FOR $250 I GET THE SAME ITEM ON AMAZON FOR $179... WHY REI? Also, the first one I purchased was leaking and the employee said it was because it was sitting dry on the shelf for too long, these filters are not supposed to get dry or else they become damaged, It was replaced thankfully but still shouldn't have happened straight out of the box.

Buy a few cause these things break soo easily. Nothing like a broken water filter mid trip with no alternatives around. Do better MSR

Heading back into eastern sierras tomorrow , looks great, this pump has seen a lot action from trickle of water in Grand Canyon to every river boat cruise

All good. Just suggest purifier tabs get packed in 12 not 10 packs to permit 2 liter treatment

The part is assembled wrong and won’t work in my pump. Completely useless.

Backpacking and international travel. This thing cannot be beat.

Would not have needed it if the original nut was built better.
