Homemade Water Filter! the 3-stage Tuna-Can Water Purifier!

Homemade Water Filter! The 3-stage "Tuna-Can" water purifier! simple to make. works fast. made with 3 tuna cans, a plastic bottle and coffee filters (along with sand, gravel and activated carbon). great for SHTF Emergency, camping/hiking, off-gridding or everyday use. activated carbon filtering removes hundreds of contaminants from water and cleans the water of dirt, silt and sediment. it also removes any bad taste/odor or color and restores it's clarity and good taste. *the 3 cartridge system keeps each level separate so mixing won't occur and it makes it easy to clean or replace each level as necessary. also makes it easy to dry. just take apart and air dry after each use.

1.) Three tuna cans (or cat food cans etc...)

2.) One plastic bottle. i used a 'great value' brand applesauce container (from walmart)

3.) Three coffee filters

4.) gravel

5.) sand

6.) activated carbon *found at any fish/aquarium supplies store or (walmart sells it for $6.00 a jug)

i just used a utility knife for this. tin snips or heavy duty scissors should work too

cut all the way down from top to bottom.

drill a series of small 1/4" holes in the bottom of each can (see pics above)

for each can; cut a circle out of the coffee filter paper (the diameter of the bottom of each can) and place one in each can so that it covers the holes

fill one can with gravel, one with sand and one with activated carbon. (remember to rinse the activated carbon until the water runs clear before adding it to the can.

place the one with the activated carbon in first, then the one with the sand in it and lastly the one with gravel.

now just set the unit on top of a glass (or any collection container) and pour in the water you want to filter. when you're done using it, dry it out and you'll be good to go for the next time!
