A dehumidifier is a useful tool to have at hand, especially if you live in humid areas. Humid air contains many bacteria and adversely affects the quality of life. A dehumidifier can clean the water vapors from the air, rendering it fresh and clean.

In the process of dehumidifying, the tank collects a lot of water from the air. It would be great if you can utilize the water somehow. It crosses the mind of many people, whether dehumidifier water is safe to drink.

The answer is no, dehumidifier water is not drinkable. You’d want to know the details. Read on.

Why you shouldn’t drink water from a dehumidifier

Dehumidifiers work on two principles: refrigeration and absorption.

In refrigeration, humid air passes through chilled coils or grills with the help of an electric fan. When the water hits the cold surface, it condenses, and the clean air is sent back into the room.

A drip chamber present in the dehumidifier collects the condensed water. Although the water vapors go through the condensation process, the water, at this stage, is still not clean. Mold spores and bacteria are common in humid air, and the condensation process cannot purify the water from such impurities.

The other method uses a combination of absorption and adsorption. In this type of dehumidifier, water-absorbing material covers the entirety of a large cage.

This cage revolves and absorbs most of the humidity in the air. Consequently, the air becomes much less humid than before.

The next step is a hot electrical fan that blows warm air. When air passes in front of the fan, drainage of the rest of the vapors in the atmosphere occurs. Lastly, the dehumidifier releases the now clean air back into the room.

Both dehumidification methods are thorough in their job, but they still are not successful in making it drinkable. Many people mistake dehumidification for distillation. Hence, they think it is safe to drink this water. But both processes are entirely different and serve completely other purposes; dehumidifier water is not distilled.

How is condensation different from distillation?

You can purify water through distillation. The distillation apparatus brings the water to a boil through heating. As a result, the water evaporates, leaving behind all the impurities. These water vapors then move to another container. This container contains a cold surface that condenses the vapors, turning them into liquid water.

Distilled water is pure and safe to drink.

The difference between distillation and condensation is evaporation. A dehumidifier does not evaporate the water before condensing. In turn, the water from a dehumidifier comes out unclean and undrinkable.

How to make dehumidifier water drinkable?

Although the dehumidifier water is not pure, you can certainly treat the water to make it drinkable. Purification of water takes place through several methods.


Through the process of distillation, you can remove the microbes from the water and make it drinkable. You have already read about the methodology of distillation above.

Reverse osmosis

Reverse osmosis is another water purification method. It uses a partially permeable surface or membrane. When water passes through this surface, all the impurities and giant molecules are caught in the body, leaving the water safe for use.

You can purify the water from the dehumidifier through the methods mentioned above. However, it is still not recommended to use this water for drinking.

Many factors play a role in making water pure. Maybe the material of the drip chamber is not suitable for intake. For these reasons, you should avoid drinking this water even after treating it.

Where can you use dehumidifier water?

If you cannot drink dehumidifier water, do you throw it away? Absolutely not.

You can utilize water from a dehumidifier for various purposes:

  • You can use this water in your car radiator’s tank.
  • Dehumidifier water is also usable in the windshield wiper tank.
  • A steam iron requires water. You can use water from your dehumidifier to fill it.
  • It can water and irrigate your plants.
  • Filling the water reserve tank of your toilet is another way to use it.
  • By mixing dehumidifier water with cleaning agents and ammonia, you can use this water for washing and cleaning the house.

Key takeaways

Although dehumidifier water goes through the process of condensation, it is still not safe for drinking. Let us walk you through the essential points in the article:

  • Dehumidifier water goes through condensation, not distillation.
  • Distillation uses evaporation to make water pure and keep the minerals intact.
  • Distillation is not the same as condensation.
  • You can treat dehumidified water to make it pure.
  • Even purified water is not safe for drinking.
  • However, you can use it for various household purposes like irrigating plants.

In conclusion, you should not waste anything but for your health and safety, avoid drinking dehumidifier water.
