Works great. I’ve used it twice in the last couple years. Most recently used it this past weekend. Cleaned, dried out, and lubricated today.

Filters water fast and down to .2 microns. Too bulky for my current use. Can be used standalone or connected to a pressurized water source if you buy an additional attachment from Katadyn.

Comes with the activated carbon bags for your use. Can filter nasty/chemical tasting water into safe good tasting water.
