Intro: Filter Saving Pre-Filtration Method - Keep the Gunk Out of Your Water Filter!
When you're backpacking or even going on a long day hike, making water safe for drinking is one of the most important parts of ensuring a fun and safe outdoor experience. Even with a proper filter, sometimes water sources are less than ideal for obtaining life-sustaining H2O - that's where pre-filtration can come in handy!
WARNING: This is NOT a substitute for proper filtration. This method is to be used in conjunction with a water filter in cases where water sources have a lot of sediment or large particles that would cause clogging or improper filtering with just a regular water filter.
Step 1: Materials
Container for water: This can be anything that holds water, but I would recommend something with a small opening, as it makes keeping the cheesecloth on much easier. We used a 3-liter water jug and it worked perfectly.
Rope: This is optional, it's for attaching the bottle to a pack.
Cheese Cloth: I cut this into strips prior to our backpacking trip, now that I've used this method a few times I would recommend cutting them into squares that completely cover the opening of the container you're using. You'll need several layers of cheese cloth, enough to make a small pad.
Rubber Band: Used to attach the cheese cloth to the water container.
Step 2: Optional: Attach the Rope to the Bottle
If you're a knot person, have a blast with all of your fancy rope tying skills. If you're like me and just want a knot that will hold your bottle to your backpack, a simple square knot will do just fine.
Step 3: Fill Your Water Container
Pretty self explanatory but do try to keep as much sediment out of the container as possible; the less there is in the original water, the less strain you put on your filter!
Step 4: Prepare Your Cheese Cloth
As cheese cloth has large holes in it, you'll need to layer several pieces. I cut mine into a long strip and just folded it over itself, making sure the square was big enough to completely cover the opening of the water container.
Step 5: Attach the Cheese Cloth to the Water Container Using the Rubber Band
Again, not rocket science, but be sure that the rubber band is tight over the cheese cloth. It would be a shame to get the water collected and then have the rubber band slip while pouring the water into your filter!
Step 6: Pour Sediment Filled Water Through the Cheesecloth
It should come out much cleaner than it goes in!
*If you have a pump filter, use another container to catch the water as it's being poured through the cheese cloth. Then you can pump the water exactly as you normally would.
Step 7: Filter Water Through Your Regular Filter
Rejoice in the fact that you spared your water filter the agony of getting clogged up by all that gunk!
