  Great that altitude sports got it to me same day so my canoe trip I didn't have to bring more water. Its all one piece so easy to replace. . . my last one died because it failed after being frozen.

  Very long lasting filter

  Probably won’t need it but good to have a spare on hand. These filters are rated for over 10 000 litres and from what I understand they stopped testing at 10 000 as there was no appreciable drop in performance. Hard to beat that!

  As you would expect. A guardian filter replacement, fits perfectly, as it should and operates as normal. Filters is perfect for group camping and leave water tasting clear as always. Solid filter.

  This filter replacement was received 2 days earlier than expected and it is a great buy considering that you never know when you will need a different way to obtain your water if your current cartridge becomes invalid. It is exactly how it is described and knowing I have it I feel better since I am capable in helping more people if things become difficult. Everyone should have a water filter and it’s replacement cartridges for whatever happens since no one can go on without water.
