Can You Drink Dehumidifier Water ? Is It Safe For Drinking?

Dehumidifiers can be very useful, especially for people who live in humid environments. It can remove water vapors from the atmosphere & reduce humidity. But can you drink dehumidifier water? The answer is no dehumidifier-water is not safe for drinking. Consuming it can expose you to lead, metals, and bacteria. As we know, water is an important resource. It is vital to conserve water. You can reduce water waste by not dumping gallons of your dehumidifier tank. These gallons of dehumidifier water can be used for other purposes, even though they cannot be consumed. This is a great way to save water.

Is dehumidifier water safe to drink?

You should not drink dehumidifier water. There are many reasons for this. Water from tap or bottle undergoes boiling, filtration and other processes to make it safe to drink. Dehumidifiers water is not filtered like drinking water. Instead, it is condensed, collected and stored. This is why it can contain pathogens and airborne particles. Plus the tank of a dehumidifier could become stagnant over time. This could lead both to bacteria and mold growth. Dehumidifier water isn’t safe to consume, not even for your pets.

How does a dehumidifier work?

A dehumidifier works in a similar way to a vacuum cleaner. It takes in the air from the room at one end, extracts the moisture, and then blows it out again into the room. The moisture is absorbed into a tank which you must empty from time to time. Basically the fan draws in moistened air and passes it through some cold coils. As air cools, it loses moisture. After this the dehumidifier heats the air then blows it outside to lower the humidity.

How much water a dehumidifier collect in a day?

The dehumidifier’s water removal rate is easiest to measure. It is measured in liters or in pints and is collected over 24 hours. The dehumidifier’s ability to draw out water will vary between machines. Larger machines can take out more water while smaller machines can take out less. The amount of water a dehumidifier is able to collect in a given day is dependent on its capacity. It can collect anywhere from 10 to 100 pints of water depending on how humid your home is.

Is dehumidifier water distilled?

Water from a dehumidifier can be very clear but not distilled. It should not be used as a drinking water source. Distillation is a way to purify water. It is a process in which water boils and then condenses into liquid. This kills most pathogens. Water that has evaporated leaves behind minerals and contaminants. Dehumidifiers work differently from distilleries. The humidifier’s water could contain biological contaminants like bacteria, minerals, and mold inhibitors.

Is it safe to drink water from a dehumidifier if you boil it?

Even boiled, it is not safe to drink water from dehumidifiers. Because water can also contain other contaminants that boiling will not remove. Means, it won’t eliminate heavy metal contaminants like iron, mercury, or other elements. In short, boiling water from a humidifier is not safe for drinking. You should choose distilled water or bottled water if you need clean, fresh water to drink regularly.

What is the difference between condensation and distillation?

Evaporation is the difference between distillation or condensation. A dehumidifier does not evaporate the water before it condenses.

How to make water from a dehumidifier drinkable?

The water from the dehumidifier is not purified, but it can be treated to make it drinkable. There are many ways to purify water. One of them is distillation & other is reverse osmosis. Distillation is a process that removes microbes from water to make it drinkable. Reverse Osmosis works by using a membrane or partially permeable surface. Water flows through the membrane. Large molecules and impurities remain trapped within the body. This makes the water safe to drink.

What’s the pH of dehumidifier water?

Water from dehumidifiers will be alkaline. It has pH between 8.7 to 9.5. Safe drinking water should have a pH between 6.5 to 8.5. Anything higher can cause health problems.

Where can you use dehumidifier water?

Do you throw away dehumidifier water if you are unable to drink it? You shouldn’t. You can use water from your dehumidifier for many purposes. Some examples include:

  • This water can be used for filling the tank of an toilet.
  • This water can be used to refill your car’s radiator tank.
  • You can also use dehumidifier water in your windshield wiper tank.
  • Dehumidifier water can be used in steam irons.
  • Dehumidifier water can be used to water your plants.
  • You can use dehumidifier water in washing machine.

Is dehumidifier water safe for plants?

Dehumidifier water can be used to water indoor/garden plants even though it isn’t considered potable water. Remember that water contains no minerals, which can affect the long-term health and well-being of your plants. You can use tap water in combination with a dehumidifier water to balance. Dehumidifier water is great for hydroponic plants. Just make sure to add nutrients and check the PH before you use it.

Is dehumidifier water suitable for batteries, irons?

Irons need soft water while batteries need pure water. So yes for irons but no for batteries. You can still use dehumidifier water to the battery but it will drain faster because of condensate. Mineral deposits may build up in steam iron iron due to the tap water. You can save steam iron by using dehumidifiers water.

Does deionized water come from a dehumidifier?

It is not deionized. Deionization is the process of removing ions from a substance to make it pure. Means it’s not drinking water.

Can you use dehumidifier water in a humidifier ?

Humidifiers disperse water to the environment, while dehumidifiers extract water from the air. Both serve the same purpose: to achieve a comfortable, recommended level of relative humidity in your home. But you can’t use dehumidifier water in a humidifier. You should fill the humidifier tank with either distilled or boiling water. Because stagnant water in an unclean bucket for a long time can lead to mold, mildew, and other problems.


If your home has clean air, dehumidifier water is safe to use for cleaning and watering plants. It is important to keep in mind that the dehumidifier water could contain harmful mold spores or suspended algae & dissolved metals and chemicals. The key point is dehumidifier water is not safe to drink, even though it undergoes the condensation process. Keep remember distillation is different from condensation. Avoid dehumidifier water as it can lead to serious health problems.
