Dewpointe DH9 – Humidity powered water cooler


The Dewpointe DH9 is a water generator that draws humidity from the air, condenses it and purifies it for drinking. The makers claim it can make drinking water for US$0.60 per gallon. When it’s used in a temperature range of 15�C to 40�C and 60% humidity the DH9 can make around 22 litres of 99.99% pure water every 24 hours. If that’s not enough you can also plug in an existing water supply and have it filtered to top up the supply.

Whilst it sounds like a good idea on the surface and Dewpointe are pitching it as an environmentally-friendly alternative to bottled water, the devil is well and truly in the details. For starters, the Dewpointe has 10 filters, including UV lamps, charcoal filters, electrostatic air filters, reverse osmosis filter and a sediment filter. These need to be replaced regularly and I imagine are a little more complicated to make than a water bottle. Granted, they probably filter thousands of litres but they’re still consumables.

The water generator also needs power, 500 W if all it’s doing is making water. If you want the refrigerated or heated water options, then the power draw goes up to around 1.1 kW just to make water. The DH9 unit is priced at US$1,595.

The Dewpointe� is a revolutionary appliance, supporting water conservation while creating the purest possible drinking water with no plastic bottle or water waste.

  • Thanks so very much for posting the new information about our Dewpointe® DH9 Atmospheric Water System. Regarding the filters in our system, Some need to be replaced every year and some need to be replaced every other year. The annual amortized retail cost for filter replacement is about $115 a year. Based on a minimum of three gallons a day of water production, or 1,095 gallons a year, the amortized cost per gallon is about $.10. As the water production increases, the amortized filter cost decreases.

    • Hi, thanks for the update.

      Is there a reason the Dewpointe is so extensively filtered?
      I may have a simplified view of it but surely if you're condensing humid air, you need to have clean air (via the electrostatic filter) and methods to stop bugs growing in the stored water (via UV lamps). What are the rest of the filters removing from the condensate?


    • How much does the electricity cost? That is, if there is any where these might be needed.
