    I was dumping out the water from my dehumidifier the other day and I thought to myself "What a waste of clean water!" So I started collecting it and soon had five gallons of very clean water. Since the source is humidity from the air there are few if any minerals in the water. Not sure if it is drinking quality but will save it to put back into the humidifier in the dry months of the winter. Has anyone else used this water source?? What do you guys know about using it?

    I saw this somewhere on the web.

    Then I found this.

    Dehumidifier + water purifier = Air2Water potable water device - Engadget

    And this:


    So I guess it depends. Looks like they all agree that you could use it for watering your plants, but you might want to run it through a filter to make it safe to drink.

    Something else to consider is dehumidifiers can also be breeding ground for molds. Use a sanitizer like bleach or Star San to keep it in check every time you empty the resivoir.

    Very true. The reservoir needs to be sanitized and the steaming unit should also be soaked in vinegar for 10 minutes then you should run hot water through it until there are no more hard water minerals are coming out.

    I got hit real hard by mold from a humidifier and had to call medvisit for a house call. The unit basically pumped the spores right into the air. The doctor showed up and wrote me a script for some heavy duty medication.

    I'd stay away from that water unless you pass it thought a 1 micron ceramic filter.

    Really? Had you cleaned it properly and everything?

    My wife took it out of storage and just started running it. I didn't even realize it was going until later that night when I couldn't breathe. Scary stuff. My wife relies on me to take care of the upkeep on everything in the house. For some reason she never asked me to clean it and get it ready. She didn't think it would be a big deal. For some reason it had no effect on her. Just me.

    drinking water containing mold spores is different from breathing them in & having them proliferate in your alveoli, but the toxins could build up over time... and filtering most water is just good practice IMO anyways

    Can the water out of dehumidifier be used in the Lead-Acid batteries?

    Humidifier = adds water to the air. Yes, they must be kept very clean.

    Dehumidifier = takes humidity out of the air.
    I think the water that comes out is pretty dang clean. It would take many years to strip any copper off of the coils, and I doubt the distilled water (which is what a dehumidifier makes) is very corrosive at all.

    actually a dehumidifier works much like an air conditioner; warmer, moist air enters the dehumidifier and then crosses refrigerant cooled coils, causing the moisture in the air to condense on coils within the machine. The moisture then collects in a drip pan or bucket for disposal while the air is slightly reheated before being discharged. The reheat process is done by capturing and using heat generated from the energy spent to cool the air. By being slightly warmed, the air exiting the dehumidifier is dry and warm (thereby creating living conditions that are less hospitable to dust mites, mold and other allergenic organisms), which means it will attract moisture like a magnet and maximize the dehumidifier's efficiency. Any contaminants floating in the air may or may not flow into the bucket.

    I'd treat that water just like any other unknown water source. Purifiy the dickens outa it before drinkin it. I know I wouldn't drink the water outa mine an it gets cleaned regular. I just won't take the chance.

    Filter, boil, chem treat (pick yer favorite) an then it could be drinkin water. No need ta take a chance on gettin sick.

    If yer savin it ta put back inta yer humidfier, I'd be treatin it to, never know what be grown in that water. Remember Legionaires disease?!

    On a side note: I remeber the boy sayin when they was in Iraq, the iraqi truck drivers would drink the water from the AC units on the trucks, never treatin it, ever once in awhile somebody would get sicker then the local dog.

    with the low humidity there I would put money on something they already had on their persons, like E. coli... but then again, a LOT of germs are of the 'just add water' variety just waiting for some H2O to proliferate

    We use an Ecoloblue Model 30 (air to water machine)

    It comes in handy especially after a natural disaster (we just experienced a hurricane), when potable tap and bottled water suppies are hard to obtain. Should we lose power, we plug it into our battery backup. This solution works out well for our family. If you want more details, click "self sufficient" below:

    water from a dehumidifer is just like distilled water ,no minerials but the mold and possible bacteria needs to be worked on to make it drinkable. Good topic

    Not to burst your bubble guys, that would be nice to have, don't get me wrong, but I think that it is a one use item, mainly because once filled, how are you going to get all of the water out if you don't need it? How do you stop bacteria/mold from growing in it?
