Many kitchens have water filters directly built into them, or they're attached to the refrigerator and ice maker.
In a "bug out" or survival situation, these kitchen water filters can be modified and converted into portable gravity water filters.
You'll need an empty 2-liter bottle, an adhesive, and a cutting tool or knife.
DIY Gravity Water Filter Using a Kitchen Purifier
First Cut The Cap Off
You will need the cap later when you attach it to the side of the bottle.
Remove Top Of Bottle
Now use your knife to cut the top part of the bottle off. You're going to use this as your funnel.
Attach The Filter
You may want to measure the width of the filter before you cut the top off so that it's a snug fit.
Use your adhesive or glue gun to attach the filter to the bottle.
Cut Hole On Bottom Of Bottle
Cut a small hole in the bottle side of your bottle.
Take the cap that you cut off earlier and glue it to the hole.
This is your new water spout.
It will allow dirty water to travel through the top and then end up as clean water that you can drink when you remove the cap.
Pour Dirty Water Into Filter
Once your glue has dried, you can begin to test your filter.
Slide it in and make sure everything fits properly.
Also, check to see that contaminated water can get in through any cracks.
Once you've tested your filter for cracks, you can start using it.
