Introduction: DIY Atmospheric Drinking Water Generator

Atmospheric Water Generator

Introduction
I can't drink the water supplied from our city,  and the atmospheric Water generators out there cost more than many can afford.  So I made one for a little over $300.  That is one sixth the price of a lowest costing unit sold online.

Parts
1 - New Dehumidifier (this brand is Kolin) $225
1 - New Extreme Water Filter system (hardware or Home shops) $125 in the US.
1 - 32" piece of clear vinyl tubing (found at Aquarium shops) $3
1 - Servo Voltage Regulator (in case of power fluctuations) $75
2 - 4"X9" 3M scrubber pads $2
1 - Zip tie 10cents

Tools
3/4 inch drill with a 1/2 inch drill bit
Philip Screwdriver
Scissors

Instructions
1) Remove all covers to your new dehumidifier. Rinse inside out thoroughly with garden hose don't use high pressure it will damage condenser flanges. dry completely before using.
2) Remove knock out for hose on back cover
3) Run clear vinyl tube through knock out and attach to hose connector inside the Dehumidifier (this will by pass the
internal one gallon reservoir )
4) Cut the 3M scrubber pads to fit air filter holder on front of machine for air filter (original filter does not trap a lot
of dust) attach filter holder to front panel.
5) Wash water filter Unit and filter before use. This unit has a 1 micron ceramic filter in top and a five stage filter in
the bottom.
6) Drill hole in top of filter unit and run vinyl tubing into the filter. Be sure not to crimp hose. Place top on filter
unit.
7) Plug unit into servo regulator and you are ready to make water from the air.

Turn on machine run for 6-8 hours depending on humidity levels to fill upper filter area.
Allow water to filter into the lower storage area.
Water comes out Neutral at 6.0 pH after filters it will be around 7.4-8.0 depending on what type of mineralization filters you used

    Legionaire's disease is passed through dehumidifier water. Are these filters good enough to filter that out?

    yes a micron one should remove any virus or disease with no problem.

    Just MHO: 1 micron - 1000 nanometers. Coronavirus SARS-2v (Covid-19) is 160 nm. The math says it would go thru, that is, not considering any electro-static effects, which very well may cause a 1 micron filter to catch Coronavirus.

    Filter with a water filter, putting silver coin into a 1 gallon holding take works remarkably well against many things but mostly stop worrying about a political virus. Wife a MD many friends all say virus real like flu but the pandemic is a hoax.

    I just ordered the Lifestraw Family 1.0 water purifier system. You can put pond water into that thing, and purified water will come out the other end. If that won't kill viruses and bacteria, nothing will.

    I designed this before there was a Lifestraw. However you cannot produce large amounts of purified water with a lifestraw. It is micron-1 as well.

    Thank you. I didn't know that the Life Straw couldn't produce large amounts of purified water.

    its the silver oxide that kills bacteria. also distilled water is pure water and has a very small effect on silver. probably shouldn't rely on it with distilled water.

    "Silver does not react with pure water. Is is stable in both water and air."

    Then there is no filter that will work as the lowest is micron-1. Even lifestraw is micron-1. It is used out doors where the COV-19 is very low. Unless an infected person coughs directly into the machine. It will most likely be killed off by the Suns UV before it enters the machine.

    Filters require maitenance. They need cleaning and replacement. Many folks don't follow the rules.

    any Ceramic filter with a micron 1 will filter out disease. always keep you unit clean and periodically change your filters.

    Oh, legionaire's disease from what I gather can be in any water system,,, there are filter systems to prevent or help prevent, but nothing is 100%... It thrives in stagnant water that is 68-113 degrees, which anything coming from your hot water tank could possibly have it,,, from what I have also gathered, to remove it from your water system, you would have to have the pipes cleaned with intense heat,,, ( I suspect a seam system to blow out your pipes or something,,, you could always search and ask around, Im working on the same issue also.... and its not just about a micron filter,,, search around and be sure yourself... there are even places that sell filter systems in a faucet or shower head that is to help prevent,,, but the key word here is PREVENT.... I do not know if it can live in extremely hot water, 115 degrees and above,,,, or colder temps, but, if they thrive in 68-113 degrees,,, extremely cold water should help, until its heated, but you also want to keep the water moving, constantly,,, this helps it from going stagnant... even some kind of stir system in a bottom of a barrel or something,,,

    Attempting to build one of these. I'm in the USA so unfortunately the 240v units you listed won't work. Also, I'm looking to get a bit more water for daily use. Anywhere between 4 to 6 gallon should be sufficient but more is better. My relative humidity is between 45% and 90% depending upon season. What do you expect my real world harvest would be? 2 to 4 gallon?

    I'm having relative success on finding a unit but I've ran into a few problems.
    My requirements SEEM relatively simple; but just asking for a little more help.

    Looking for:

    * Decent sized unit (70 pint / 8 gallon)
    * One that has a tube or even better a continuous flow drain port
    * Around a $200 budget for this unit (not counting the filter, etc)
    * Runs off 110v, and preferably around/under 600 watts (for solar)

    What could you recommend?

    Other question: I'm looking at getting the Zen water filter but I don't understand how the filters work. I saw an update where you said you're now using 2 different filters.

    Will this one work?
    http://zenwatersystems.com/products/rejuvenate

    Will these filters help with units potentially leaching aluminum from the dehumidifier? The whole point of this project is to have MUCH better quality water than what I'm getting on tap - which shouldn't be too difficult. If I drank straight mud puddle water, I'd be in better shape than the nasty stuff from the faucet.

    I too am now in the States. Use a new unit. Use a colloidal silver filter like the stephani, the one linked below it is good for bacteria and metals and the Berky PF4 for heavy metal leaching. between the two of these filter you could get 99.9% of all metals out if there is any leaching. The water is great it is like rain water around 6.2-6.0 in pH. the Stephani filter is a good filter and it is micro 1 so most viruses and bacteria wont get through.

    Perfect, thanks for all your help! I also forgot to thank you for the instructable in my last post.

    One last question. Will the Stefani + Berkley filter fit the Zen water tank?
    More specifically, do all water tanks use a standard so that these filters fit?

    I'm just curious because if for any reason they stop selling these particular filters, I'd like to purchase alternatives instead of having to buy a whole new holding/filtering tank.

    It would also be great if I could find a filter that raises the PH to around 7.0 - 7.5 in addition to all of the filtering capabilities of the Steffani Colloidal Silver ceramic Candle. Or maybe I can stack the filters somehow?

    I suppose as a last resort I could lead the filtered water into an alkalizing type machine.

    If it is similar to the one in my instructable, yes it will fit. You may need to cut the the threaded end a little shorter (use the nylon rubber gasket that comes with it to seal it off) and put in through the hole then tighten the Berky onto it.
    The Zen I believe, if it is like mine, also comes with a mineralizer that sits in the bottom of the storage tank area and allows the water to get minerals added to it. Be careful with that because it can make the water really hard high pH. This is not distilled water it is atmospheric so it is like rain water neutral Ph about 6.2-6.0 that water is neither Acidic or Alkaline so it doesn't leach your bodies minerals.
    Remember you can build you own filter system from some plastic water jugs with a little modification and imagination, be sure the bottom has a spout so you can get a glass directly from it.
    I Plan on an additional instructable to this one showing how to do make you own filter system using plastic jugs and the two filters.
    Most
    dehumidifiers remove about 18 gallons of water in a 24 period in any
    humidity above 50%. When it is 100% wow it will make more.

    I very much appreciate you taking the time to answer all of my questions. I seriously can't thank you enough. When this is all done, I promise I'll give you a nice tip/donation!

    Okay, I lied.. I have more questions. lol. Sorry about bothering you!

    What are your thoughts about the filters that comes with the Zen unit?

    According to the brochure, the top filter (Micro-Ceramic Filter dome) is the first line of defense filtering out impurities, bacteria, pesticides etc. It has a pore diameter of 0.2 microns. I believe you're replacing it with the Stefani which only has a 1.5 micron filter.

    Can you tell me how these two compete? Wouldn't it be better to use the filter it comes with and save myself some money?

    Furthermore, the bottom filter the unit comes with is a 6 stage filter which features some pretty impressive things.

    You can see the graphic here:

    http://i.ebayimg.com/images/g/HoQAAOxy9eVRL6W-/s-l...


    1 = The top candle filter

    2 = Silver impregnated granulate activated carbon

    3 = Ionic Exchange resin (apparently softens water and removes heavy metals)

    4 = Far Inrared balls (Activates water molecules for better health?)

    5 = Silica Sand (better PH, which is kind of what I was asking for in last comment)

    6 = Mineral Stones (more minerals in your water is always better)

    How does that compete with the Berkey filter?


    On the water PH and heaviness - I know that there is serious debate about Alkaline water. That aside, my mom has cancer and she's into the higher PH water. I'm also making the assumption that more minerals in her diet would be a good thing as she's not eating hardly anything. What are your thoughts?
