Clean living

by RwII, from WA, United States Written on October 13, 2021
This is the last water filter you will ever buy. The flow rate is excellent and makes the trip to the watering hole a lot less painful. It’s expensive but usually things that work well are worth it! Especially when it comes to having a Clean reliable water source.

Best All Around

by Kyle, from CA, United States Written on September 16, 2018
Love this thing. It's more like the state of mind that you can rely on exceptional gear without hesitation.i just wish I had this with me in my last trip to Peru. My girlfriend calls me crazy for spending so much money on gadgets. But people sometime don't think about the luxury items of what we have here in the states and having good clean water is probably one of the most overlooked nesiscities when traveling or backpacking.
Best Used for:

Safe Water in 3rd World

by Fred T., from CA, United States Written on July 7, 2017
Filters that are less expensive will do in pristine environments, but in a highly polluted environment of a third world country you need the Guardian. Yes it is expensive. Yes it is 17 ounces! The Guardian delivers peace of mind and clean water! The health of you and your group demand nothing less! Get the Guardian!

Preliminary Review

by Ramsey S., Verified Owner from CO, United States Written on January 4, 2017
Bought this filter to use on a two month trip from Arizona to New Mexico. Seems like a solid filter, and it promises a lot. Came with a case. Will offer more thoughts once I have finished the trip.

Seems legit

by Silly, from IL, United States Written on April 30, 2016
Well it looks like it's going to work. Haven't used it in the field yet but it certainly produces faster than my hiker pro and I like the direction the pump ark moves much better as well. Less fatigue for sure and it's a one man operation with comfort. Hiker pro was better with two people just to hold the hose when filling multiple bottles. Not a ton heavier either and almost as compact. Almost.
Would recommend: Yes
