Did you know that water is a precious resource for over 1.1 billion people around the world? It is no wonder that water conservation is so important. So, stop throwing away gallons of water from your dehumidifier’s tank.

Instead, you can reuse the water for many other purposes, which is an excellent way to help save water.

In this post, we have given the adequate uses of dehumidifier water. 

How Does a Dehumidifier Work?

To know why we can use dehumidifier water for some stuff and not others, let’s talk about how this unit collects water.

A dehumidifier runs on the same principles as air conditioning systems do. It draws in moisture from the air with the help of a fan and then passes it through some chilled coils.

As the air cools down, it is unable to hold moisture any longer. Consequently, water droplets form as a result of condensation, leaving the air dry.

The dehumidifier then reheats the air and blows it outside, lowering the humidity. What about the condensate. It collects in the tank of the dehumidifier and waits for you to empty it.

Is Dehumidifier Water Distilled?

The way a dehumidifier removes humidity from the air looks similar to how distillation works. However, dehumidifier water is not distilled, although it comes close to that category.

When water is heated and then turned into steam, distillation occurs. This process kills most pathogens. After that, water evaporates, leaving behind minerals and other contaminants. The steam is very pure and clean when it cools down to liquid form.

Your dehumidifier, on the other hand, doesn’t heat or convert moisture into steam. Instead, it draws moisture out of the air through condensation.

Dehumidifier water does not contain any minerals. This is why it is similar to distilled water. However, it doesn’t go through the same treatment, so it isn’t as safe and pure.

Can You Drink Water from a Dehumidifier?

Dehumidifier water is not safe for drinking, and there are many reasons for this.

Tap water and water bottles are subject to filtration, boiling, or other procedures that make them safe for drinking. Dehumidifier water may carry airborne particles and pathogens.

Second, cooling the air with coils can leach metal into water. This could make it dangerous and toxic. The dehumidifier tank remains stagnant for a long time, which could lead to bacteria and mold growth.

Dehumidifier water is not safe to drink, even for pets. However, it is useful for other purposes, which we’ll talk about below.

Can You Water Plants with Dehumidifier Water?

Dehumidifier water is safe for indoor and garden plants, even though it isn’t considered potable water.

However, keep in mind that the water lacks minerals like calcium and magnesium, which your plants require to thrive. Therefore, only watering them with dehumidifier water can affect their growth in the long run.

Use tap water along with dehumidifier water to balance things out. Also, it is better to use this water for a hydroponic garden.

Tap water contains chlorine and other chemicals which can harm hydroponic plants. On the other hand, dehumidifier water is excellent for hydroponic plants. Just make sure to add nutrients and check the PH before you use it.
