InIn this Instructable I'm not going to show you as much some thing new as make you aware of the possibilities. Buying things to throw away drives me nuts. The phrase "When you're done, just throw it away!" never made sense and is nearly unforgivable today. Also, you aren't contributing to transportation waste by using materials about your home (I hope)
There is a plastic pitcher and filter company out there making a good buck selling the benefits of user water filtration. It uses a throw away filter. It's a great thought. I have a better one.
If you are in a rush I'll let you in on the secret right now. Instead of making coffee in a coffee maker, use the coffee maker and filter along with Activated Filter Carbon (instead of coffee) to filter your water. Who doesn't have a spare old coffee maker lying around? Don't have one? Go to a charity store and pick one up. I like to use half gallon used PET juice bottles (cleaned, c'mon) to hold the filtered water.
Activated filter Carbon - I got mine from a pet store. I called the manufacturer and they very nicely told me that it is NOT for human consumption. YOU might like to go to a health food store and buy some meant for human consumption. I recommend that method.
Drip Coffee Maker with accessories. - Carafe, filters etc.
Sieve - for rinsing the dust off the carbon particles.
Carafe - to put finished water in.
Absorbent material to mop up any possible spills.
Step 1: Wash the carbon
If you don't wash the carbon first you'll clog your little paper filter and potentially end up with some pretty gray lookin' water. Probably won't hurt but doesn't look so appetizing. No need to dry it. Use as much carbon as you would use ground coffee.
