This is a photo essay of the homemade ultralight backpacking water filter I use.
Use What You Need
Don’t waste your breath telling me this filter isn’t enough for me – or anyone else choosing to use it – and we won’t tell you your over compensating for water filtration.
It’s a free country so leave everyone to use the filter of their choice.
I’m not a water expert so only take my advice if you’re confident it will serve your needs.
Get a 1 Micron Singed Polyester 7″ x 16″ Filter Bag Felt Biodiesel Sock Size 1, open the sock into a flat piece of cloth, draw as many 8″ circles as you can (we fit four 8″ and one 7″), and cut them out.
Fold them into quarters and glue the seam (I use a hot glue gun).
Create a protective sleeve to store your filter.
These biodiesel socks will catch a lot of dirt and natural material when you lay them on the ground. To combat this I sewed fiberglass screen material to fit over the filter as protection.
You don’t have to make this cover, but it helps keep the outside of your filter clean.
Put it all together and give a few to your cheapskate, ultralight backpacking friends!
Effective water filtration at a fraction of the price.
