Dehumidifiers are designed to reduce the amount of water in the room where they’re used. They accomplish this by pulling water molecules out of the air until the absolute humidity in the room has dropped to the desired level.
The water that the humidifier extracts is collected in a built-in tank. Now what to do with the newly acquired bowl of water? Just throwing it away would be a waste. If you’re thinking of reusing the water for your humidifier, that’s a very creative idea. But is it the right idea? Read on to get the answers to all your questions.
What kind of water does the dehumidifier dispense?
The purity of water discharged from the dehumidifier depends entirely on the tank’s condition and piping inside the dehumidifier. Under normal, clean circumstances, the water that comes out of the dehumidifier is close to distilled water.
You can compare distilled water to the water vapor that condenses and collects on the coils of your refrigerator. This water is entirely safe to reuse because it contains few impurities.
However, if the water is in a very unclean state or has been sitting in the tank for a very long time, it’s definitely not safe for reuse. This water tends to be affected by long-term contact with bacteria. If you look closely, there’s a slight chance that you’ll discover the uncanny growth of mold or similar parasitic creatures.
Is Water from Dehumidifier Pure Water?
The water from dehumidifiers is clean but not pure at all? Although the water is taken directly from the environment in a pure state, it usually sits in the tank for a while. For the water to remain pure, it must be isolated from the air immediately after extraction.
As the water from the dehumidifier remains in the tank for some time, it accumulates other pollutants from the environment over time. Therefore, instead of calling the water from dehumidifiers pure, we can compare it to distilled water. We’ve already mentioned that dehumidifier water is more like the condensed water vapor that sometimes drips from air conditioners.
Can You Use Dehumidifier Water in A Humidifier?
Yes, you can use dehumidifier water in your humidifier if the dehumidifier is cleaned frequently and the water isn’t stale. Only clear dehumidifier water from a clean tank can be used in humidifiers.
We mentioned earlier that depending on how clean your dehumidifier’s tank is, the water can either be very moldy and impure or so clean that it passes for distilled water.
With moldy water, that’s not quite the case. If you’re going to use the humidifier water, you need to make sure that the quality of the water is as good as your drinking water. Because even if we don’t drink the water from the humidifier, we still absorb it through our skin and respiratory system.
Therefore, you should also clean the tanks and all auxiliary parts of the dehumidifier regularly so that you can reuse the water when needed. Only then can you use the water in the humidifier instead of just throwing it away.

Why Would You Use The Dehumidifier And The Humidifier At The Same Time?
While it’s normal to use either a humidifier or a dehumidifier, it’s rare to use both simultaneously, depending on the indoor climate. It depends entirely on the atmospheric conditions and how they affect the indoor air – you decide whether to use the humidifier and dehumidifier simultaneously or one after the other.
There are only a few situations when the simultaneous use of humidifiers and dehumidifiers is acceptable. This is the case, for example, when your water pipes break in the attic while the climate outside is less humid than usual.
In this case, the dehumidifier would lower the excess water in the air below normal. At the same time, the humidifier would raise the humidity back up a bit so that the moisture in the house is just right. The same case could occur if your attic is too damp due to snow.

In short, if you clean your dehumidifier’s tank properly regularly, you can reuse the extracted water for your humidifier.
Note, however, that while the water to be used must be of drinking quality, you shouldn’t drink the water from dehumidifiers.
