What Makes Dehumidifier Water Unsafe

What Makes Dehumidifier Water Unsafe

Let us explain the science behind the working of a dehumidifier and why it is unsafe to drink dehumidifier water. A dehumidifier works by removing excess moisture from the air in a room.

It works on the refrigeration principle, drawing in warm air, cooling it, and passing it over a condensing coil.

The cooling process causes the moisture to condense into water droplets, which are then collected and stored in a container. This water, known as condensate water, is what you are warned not to drink.

Drinking water from a dehumidifier can pose serious health hazards due to the presence of harmful contaminants, microorganisms, and bacteria that are present in the air. These contaminants can come from various sources, including building materials, household products, and the outside environment.

In most cases, the dehumidifier itself contributes to the contamination of the water. For example, the condensate water comes in contact with the internal parts of the dehumidifier, such as the fan blades, drainpipes, and condensing coils, which contain bacteria, mold, and other harmful substances.

Additionally, if the water collection container is not properly cleaned and maintained regularly, it can lead to bacteria and other harmful substances buildup over time.

When you drink water from a dehumidifier, you are ingesting these harmful substances and potentially putting your health at risk.

So, using this water for other purposes, such as washing and cleaning, is always recommended, but never for drinking or cooking.

Health Hazards Associated With Drinking Dehumidifier Water

Health Hazard Associated With Drinking Dehumidifier Water

Drinking dehumidifier water can have serious health consequences as it contains harmful contaminants, bacteria, and hazardous chemicals.

Some of the health hazards associated with drinking dehumidifier water include the following:

  1. Bacterial Infection: The water in the dehumidifier contains harmful bacteria, which can cause serious illness and infections if ingested.
  2. Mold Exposure: The water in a dehumidifier can also contain mold spores and other types of spores, which can cause respiratory problems, allergies, and other health issues when inhaled.
  3. Gastrointestinal Problems: Drinking contaminated water from a dehumidifier can cause serious digestive problems such as vomiting, diarrhea, and abdominal cramps.
  4. Heavy Metal Toxicity: Dehumidifiers contain heavy metals, such as lead, mercury, and arsenic. These metals can have serious long-term effects on your health if consumed.
  5. Chemical Poisoning: The water in a dehumidifier can also contain chemicals, such as cleaning agents, which can cause serious health problems if ingested.

Making Dehumidifier Water Drinkable

Dehumidifier water should not be consumed as it is, as it contains impurities, bacteria, and other harmful substances.

If you need to make it drinkable, there are a few methods you can use, including:

1. Boiling


Boiling is one of the simplest methods to make dehumidifier water drinkable. But first, you need to heat the water to its boiling point (100°C or 212°F) for at least one minute.

After boiling the water, allow it to cool to a safe temperature before drinking it. This method kills harmful microorganisms and bacteria in the water, making it safe to drink.


Keep in mind that boiled water may still contain some traces of contaminants.

2. Reverse Osmosis

Reverse Osmosis

Reverse osmosis (RO) is a water purification process that removes impurities from water by forcing it through a semi-permeable membrane.

The membrane allows water molecules to pass through but blocks large contaminants, such as bacteria and minerals, from passing through.

3. Distillation Process

Distillation Process

Distillation is a process that removes impurities from water by boiling it and then condensing the steam into a separate container.

During the boiling process, you can eliminate impurities and contaminants by letting pure water vapors rise and condense into a separate container, resulting in drinking water free of impurities.

4. Chemical Treatment

Chemical Treatment

Chemical treatment is another method that you can use to purify dehumidifier water. This process involves adding chemicals, such as chlorine or iodine, to the water to kill harmful bacteria.

However, use this method cautiously, as over-treatment with chemicals can form harmful by-products.


If you are unsure how to use chemical treatment methods, it is best to avoid them, as improper use can lead to other health risks.

5. Filtration System

Filtration System

A filtration system, such as a ceramic filter, uses a physical barrier to remove impurities from water.

The filter traps contaminants, such as bacteria and minerals, within the filter’s porous structure, allowing only clean water to pass through.

A filtration system can effectively remove impurities from the dehumidifier water and make it safe to drink.

While dehumidifier water is unsafe to drink directly, it can be made drinkable through methods such as boiling, reverse osmosis, distillation, filtration, or chemical treatment.

However, safe and disinfected drinking from a reputable source is always recommended.


It’s important to note that dehumidifier water should not be relied upon as a long-term source of drinking water, as it may contain substances that could be harmful if consumed over a prolonged period.

Other Uses of Dehumidifier Water

There are several alternative ways to use dehumidifier water, other than drinking it, that can be both practical and environmentally friendly:

  1. Watering Plants: You can water your indoor and outdoor plants with dehumidifier water, as it contains some excess moisture and impurities that plants love.
  2. Cleaning: You can use dehumidifier water to clean surfaces such as windows and mirrors, as it does not leave streaks or residue like tap water.
  3. Laundry: You can use dehumidifier water as a fabric softener in your laundry wash cycle.
  4. Car Washing: You can wash your car and fill the windshield washer fluid reservoir with dehumidifier water.
  5. Ironing: You can use dehumidifier water as a steam source when ironing clothes to reduce wrinkles and freshen up the fabric.
