In the past I’ve used a nylon stocking to pre-filter my water before treating with AquaMira. Now that I’m using a Sawyer Squeeze filter I’m still using the nylon stocking to prevent large particles from entering the Sawyer Squeeze. This eliminates the need to carry the bulky syringe included with the Sawyer for back flushing. Weekend trips aren’t the issue, on long distance hikes I don’t want to carry anymore than necessary and the lighter the better.
The nylon is ultralight less than 1-gram when cut to length, easy to find and sold in drug and grocery stores, about 60¢ for two and fast drying. The stockings are sold in little round containers about the size of a golf ball, two stockings per container and usually available in three colors I choose white, it’s easier to see the debris caught. These work well for both wide and small mouth bottles/bladders.
When you’re ready to catch or dip water stretch the material over the opening of the bottle/bladder. It’s best to tuck a little of the material inside the bottle/bladder to prevent spillage. For small mouth openings you can tuck more of the filter inside the bottle/bladder or trim away some of the excess material.
I used the same filter for over 600 miles in 2010 without any holes appearing, so they’re very durable.
