Use Coffee Filters to extend the life of your Water Filtration System

Water Filtration Systems have a set lifespan. After a while the filters just get worn out. You can use coffee filters to extend the life of your water filter.

Zack and I did a quick demonstration of this system in Mason jars to show how effective it can be. (Click for larger pictures)

Pre-filtering water through coffee filters removes all of the larger debris and a lot of dirt too. This can go a long way towards extending the life of your water filter because it doesn’t have to work nearly as hard.

Not to mention coffee filters are small and light enough for your Bug Out Bag

The easiest way to get water to drain through the water filter was to push it down into the container and let gravity do it’s thing. It takes a few seconds for the water to drain.

Coffee Filter Leftovers

Leftovers

We only used regular old coffee filters for this, but I poked around and found these Micro-Filters that are for espresso makers.

The description says: “The Micro-filter removes grit, unlike other press-type coffee makers” So I am assuming the filter is even more fine.

It might take longer for the water to work through, but they could be that much better for filtering out tiny grains of dirt. Find them here on Amazon: Micro Coffee Filters.

If a reader wants to test them please let me know and we’ll publish your results.

Save your Bottles

In a survival situation you might only have a few bottles. Don’t contaminate them with dirty water. Use a collapsible bucket to collect water, then coffee filter, then really filter. 6 Great Uses for a Backpacking Bucket
