Katadyn BeFree Upgrade! – Larger Water Bag & Gravity Filter System

Using the Katadyn BeFree Water Filter with a HydraPak Seeker 2L Reservoir and Gravity Filter Tubing Setup.

After my previous review of the Katadyn BeFree water filter, I discovered and acquired a compatible water reservoir bag that would increase my filtering capacity to 2L – the HydraPak Seeker collapsible water bottle (also available in a 3 liter version).  The main challenge with the BeFree filter is finding a water bottle or reservoir with wide mouth 42mm threads, which the HyrdaPak has.

In the video I go over my thoughts and experiences using the Katadyn BeFree in conjunction with the HydraPak Seeker 2L and Sawyer Squeeze 64 oz Pouch as part of a gravity water filter system, as well as a stand alone squeeze style system using just the HydraPak Seeker and BeFree.

Katadyn BeFree Water Filter Review

My thoughts & review of the Katadyn BeFree Collapsible Water Filter Bottle – 0.6 Liter for Backpacking & Camping

The Katadyn BeFree is a backpacking water filter with a very small footprint and low overall weight.  In this video I’ll cover all of the bases from the initial unboxing, to specific features, individual item weights, test usage out in the field, pros and cons based on individual backpacking styles, as well as some thoughts of future improvements for the system.

Update: After further research, it looks like there may indeed be a third party bag that works with the wide mouth threads on the BeFree filter cartridge.  It looks promising, but I have not been able to personally test it’s compatibility.  It’s called the Hydrapak Seeker 2L Water Storage Bag
