    I haven't used it yet but think it will be great camping this summer. As a Ambassador I've used the Sidekick and the Versa flo and they work great flow fast and clean water

    BWCA water filtration, shower.

    Posted by Neal Mattison on Nov 20th 2022

    While in the BWCA , my daughter and I utilized the Go Flow Water Gravity Bag, Versa Flow with Activated Carbon Filter and the Clear Flow Water Bottle and Filter Combo with great success. We used one water bag exclusively for filling with, "dirty" water. The other two were for the clean filtered water. That way we always had one full filtered bag while the other was filling. We also used one full bag for showering. I simply drained out half, heated it, then poured it back in for a hot refreshing shower. The Clear Flow Water bottle worked great while on the water away from camp by simply dipping it full and drinking. This alleviated the necessity for carring extra prefiltered water bottles. Knowing I have the necessary equipment and knowledge to purify water in any situation, I'm at rest having a plan for whatever is thrown my way. I did have to sleep wirh the Versa flow filter when the temp got down to 25°F to keep it from freezing one night. Backflushed the filter a couple of times to regain the flow rate. Don't forget to bring the backflush bottle. Have been using their products for many years and will continue to do so for years to come. It is cheap health and safety insurance.

    Exactly what I was looking for!

    Posted by Karen Aldridge on Jun 1st 2022

    This was recommended recently at a preparedness workshop I went to. I wish I would have had this system over the past many years! As a camper, hunter, backpacker and overseeing teens backpacking, this would have been well used. I may buy it for all my grown children.

    Love this filter!

    Posted by Roxanne Miller on Sep 1st 2021

    Took it backpacking with a few people and it was so much quicker than the mini “squeeze bag” filters out there.

    System works...

    Posted by Jeffry Fisker on Jun 30th 2021

    I have been using the Go Flow Water Gravity system for the last 3 years, this purchase is for a backup as the original is 3 years old at this point. It works efficiently and reliably.

    I love this thing, it holds 10 liters of nasty water, slap on the filter and it comes out clean as can be, it's great so you don't have to carry as much water with you which is vital sometimes.

    Bought the gravity filter for camping/hiking. Performed so well, I bought a couple more for the home prep kit. Great all around filters. Buy with confidence!
