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.

Material list-
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 1Wash the carbon

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.

My municipality uses asbestos pipes somewhere along the line to us. I wonder if anybody knows whether either the coffee filter or the charcoal would catch asbestos fibres that might come in. I get the impression that the charcoal (carbon) traps chemical contaminants (not fibres), and that the coffee filter might not stop everything, such as tiny fibres. ??

I use a PUR water filter on our facet and it will remove asbestos from the water, but as always will filter 99.99 percent is a lot better than 0 percent. I don't think anything will filter 100 percent of all contaminants. wont remove microscopic fibers

Is the carbon compostable? We have municipal compost. You keep saying that you're throwing less trash away, so I was wondering if that was part of it.

Water filter activated charcoal is usually made from burned organic material such as coconut shells, so would make good compost by itself. There is a concern however that the activated carbon is contaminated with the very materials you wish it to filter from your drinking water (heavy metals being the most serious). Putting this back into your compost and your food chain would not be a good idea. Some countries require drinking water filtration activated carbon to be mixed with concrete before being disposed to sequester mercury.

Sleepy,
It's not that I doubt you; I was just wondering which countries require nuke-type disposal of water filter carbon? That would be interesting info to have. Thanks in advance. Have a GR8 day.

That's good to know. I'm trying to compost as much as I can. I hate disposable items too, that's one of the reasons that I switched to Brita. Our tap water tastes awful, but the thought of buying bottled water seems so wrong. This idea is great, and I can't wait to try it!
May 13, 2009. 8:47 PMbullet71792 says:
you could always just drink the tap water. because tap water has flouride in it. and it has minerals that are good for you. so its cheaper than bottled water and its better for you.

you obviously havent tasted MY water then.....lol
Sep 6, 2009. 7:32 PMparisbabe says:
lol.....the water in this part of so. cali. tastes like fish water with chlorine mixed in for flavor....lol

Id rather have water taste like fish. You can light mine on fire

.........why dont you try ours........it looks like lemon juice with too much water.......
..........and freakn taste like prehistoric algae........
............this might work for out tap water...or maybe if i do it 3 time........

any one have solutions for my tap water ???

i just gave up and got a Britta water pitcher that has a removable filter

Exactly. Thanks for posting this! Currently Im living in the US (Michigan) and I use a Brita faucet mounted filter, but they are EXPENSIVE. Luckily, I've been able to stock up a few times when my local grocery store had some brita faucet replacement filters in the clearance bins. Last year, whilst living in Israel, where I was not comfortable drinking the tap water either, I noticed that although it was possible to find brita replacement filters at some stores, the prices were obscene, and they didnt always have a complete selection of the different types. This year when I return to Israel Im going to give this coffee machine idea some serious consideration, and tell my friends and family in Israel about it and see what they think. I mean, I havent checked yet on how much the carbon stuff costs, but I'm guessing that it's going to be much cheaper to buy that than it is to buy a replacement brita filter in israel.
Also, im so glad i read into the comments about the "cold water slime" phenomenon. This solves an annoyance I've had with my brita system for some time now! I started noticing awhile back that there was a reddish/pinkish area right where the water comes out and I actually thought it was from... chef boy ardee cast-off. no joke. i thought it had gotten there as a result of me using the sink sprayer to rinse out the cans of the chef boy ardee that my kid loves and eats on a regular basis...I've been taking toothbrushes with baking soda, trying to scrub it clean, thinking it was yucky pasta sauce residue...lol

Tap water is great & I drink it all the time, but I also have a whole house filter. I wouldn't be too excited about the fluoride. The dangers of Fluoride are well-documented, if mostly unknown by the public: http://bit.ly/c2qU7
Sep 26, 2010. 10:33 PMMike73 says:
I like the idea. But isn't it a waste of energy if you just want to have filtered water? I mean that commercial filters filter cold water. So is the result the same if you were to just use a little pump instead of a coffe maker? I can see a point if you plan on making a coffee or tea where hot water ist needed.

Please don't take this as offensive. Those were just my initial thoughts and I was curious for the answer but didn't have the time to skim through all 63 messages.
Sep 27, 2010. 7:10 AMMike73 says:
Thanks for the quick reply. I get your point allthough I really just asked because you got me interested. I've been to the US for 3 years and we always just bought bottled water exactly for the reasons you mention concerning tab water. Water here in Germany is quite fine. In my area, there's no additional stuff in the water. So mostly people just use the filters to decal the water so that appliances don't get affected. Thanks again.

You can use a Bunn brand coffee maker. You can run water through it without heating it.
Mar 8, 2010. 4:56 PMSuluSulu says:
Heating the water is mostly responsible for removing the clorine.  The carbon in this process is constantly "being washed" because the water is over 145F and is not really capturing anything.  The filter basket allows a lot of the water to channel off the sides.

If you could find a way to pump cold water through the carbon it would be much more effective.  What you have here is a Brita type water pitcher with a plug!

Instead of the coffee maker, and getting the water hot, why not use a second bottle the same size, put a small hole in the bottom and place it above the carbon and paper filter set in a large funnel in the mouth of the holding bottle. you could use either a small shelf or hang it with some string round the neck. The small hole will drip the water down into the funnel just like the coffee maker would.

i know this is trying to be reducing waste, by not wasting the plastic in a water bottle, or even save to plastic in a brita filter. but if u compared this method to the brita( or 'pure') system, i think u would have less enviromental impact with those bc they dont require electricity. having the water being pumped and heated, wastes alot of energy than just putting it in a pitcher, plus i would then have to recool down the water to drink it- thus wasting time and energy- there is also a large possibilty that a system like this would be kept plugged in and contribute more to the 'vampire' energy being wasted- cool idea but maybe not the greenest

what about people usin Blue Sky energy from Pacific Power? It all comes from renewable sources, so energy wouldn't be an issue
May 16, 2009. 5:45 PMlilyumestar says:
My family doesn't drink coffee but we bought it for the purpose of boiling water. when we started using it, my god the electric bill went sky rocket. We found out that the coffeemaker was 900 watts so it not so green in the sense that it consumes a lot of electricity. :/
May 17, 2009. 6:48 PMlilyumestar says:
Thank you for the quick response. I was more or less wondering like one of the commenter why not pour boiled water into a filter with the activated filter carbon but I guess it doesn't really work like that hahhaha Hm... We did use it for personal consumption. We used it at least twice a day. During that time, my home electric bill is around $100-$150 for a family of four but after the first several month of using it, my mother said the bill went up to around $190 - $200 something and she forbade us from using the coffee maker. After we stopped, the bill was normal. I don't know....maybe its my funky coffee maker.

I think you're right on with this one. I'm not worried about my tap water having too many contiminants, it's already been treated at the water plant. But the taste is bad. The activated charcoal plus the heat should make it much more palatable. Good job. One other thing... Once the charcoal is spent, it and the filter can be tossed in the compost.
May 14, 2009. 12:49 PMCherylTX says:
I think the carbon is neutralizing (somewhat) the chemicals that were used to make the water "drinkable". So maybe it's not so much that we're filtering out impurities but just killing the chemical taste.
May 13, 2009. 8:42 AMCherylTX says:
Running some distilled white vinegar through, will clean the coffee maker thoroughly.
May 5, 2009. 6:22 PMcharley brown says:
I am so happy I found you, we ahve used Brita filters for years and you are correct - 1 a month. I will certainly give this a try and get back to you.

Some one used the carbon and an old brita filter instead of buying another new refill.
