Air conditioners and dehumidifiers are excellent ways to reduce the humidity level in a home or office environment. All of the best dehumidifiers will have a removal water collection tank that allows you to easily dispose of the water that is collected during dehumidification. While many people simply dump this collected water down the drain or add it to their toilet tank, you may be wondering if there are more beneficial uses for the water in your dehumidifier tank, such as using it as drinking water. Let’s explore whether water from a dehumidifier is safe to drink and what other uses it may have in your home or office.
What Is In Dehumidified Water?
Similarly to refrigeration, a dehumidifier works by using cold metal tubes/cooling coils to remove heat and moisture from the air. It turns water vapor into liquid water that collects in a tank. This process means there is a fair chance that this condensed water will contain impurities and contaminants. Moist environments (such as a home that requires a dehumidifier) are also prone to developing mold and mildew; when the water from this environment is collected in a dehumidifier, it is not uncommon for these pathogens (mold spores, bacteria, and other microorganisms) to be hanging around in that water still, along with heavy metal residues such as lead that come off the metal workings inside the machine. If you don’t clean your tank often enough or thoroughly enough, algae may also begin to grow and add to the multitude of pollutants already contained in the water that the dehumidifier collects.
Is Dehumidifier Water Drinkable?
Are you looking to find an answer to the question, “Is dehumidifier water safe?” In short, the answer is no. With the amount of water collected in a dehumidifier over the course of a week will seem like a lot, drinking this water is not a safe way to avoid wasting that water. Your one main takeaway here should be that dehumidifier water is NOT potable water. As you may have gathered from the previous section, the water that accumulates in a dehumidifier tank is not clean water. It contains microbes and many other contaminants that have the potential to make you sick.
Cleaning your dehumidifier’s water tank with bleach is a great way to eliminate mold and other pathogens, but again, even this does not make the water safe to drink. The condensation process can still lead to the collection of other harmful substances that you don’t want to be putting into your body. Unlike an air purifier, a dehumidifier cannot remove harmful components of the warm air that is filtered through it.
What About Reverse Osmosis and Distillation Techniques?
When using a humidifier that adds moisture to the air, you should always use reverse osmosis water or distilled water rather than tap water to prevent the machine from adding harmful substances to the air you breathe; when using a dehumidifier that collects those substances already floating around, it makes sense that you shouldn’t introduce them to your body through drinking either.
While there are machines that use reverse osmosis and distillation techniques to create ultra safe drinking water, there aren’t any dehumidifiers on the market equipped with these capabilities. If you are truly set on purifying the water that comes out of your dehumidifier, distillation and reverse osmosis are the only ways to go about it. This may open up some more uses for the water, but even with these techniques, it is still recommended that you do not ingest the water.
What Can You Use Dehumidifier Water For?
Dehumidifier water has many uses that you may just not have thought of yet. Wasting water is not a very conscientious thing to do, so follow some of these tips to re-purpose the non pure water that collects in your dehumidifier.
Watering plants may be one of the best uses for your dehumidifier water. Unless you put the water through a water filter or other water purification system, it is not recommended that you use the water fro plants that you intend to eat. However, other garden/house plants that are just decorative will likely respond just fine to the water from your dehumidifier rather than from your tap.
If you don’t have any plants in need of a regular drink, using your dehumidifier water to flush your toilets is the next best thing. Simply add the water to the toilet tank before flushing. It will take a little bit of time to remove the heavy toilet lid and replace it afterwards, but it is an excellent way to conserve tap water and make use of a resource that you don’t need to use in any other way.
Fill Steam Irons
Filling your steam iron tank is a great way to save on tap water and use up your dehumidifier water in an ethical way. Steam irons can use a lot of water depending on how much they get used, and dehumidifier water will actually be better for the iron than tap water in certain regions since it will contain less minerals that can damage the iron in the long run.
Another excellent use for dehumidifier water is for cleaning around the home. It is an excellent resource for mopping floors or washing various surfaces, especially with the addition of a little vinegar or bleach since it will kill all potential contaminants in the water and also act as a safe, homemade cleaning product for your home to reduce toxins from standard cleaners. The water can also be used outdoors for washing your vehicle (don’t add bleach or vinegar!) or outdoor decor items.
Fill the Radiator
Our final suggestion to help you get rid of your dehumidifier water in a way that feels better than dumping it down the sink is to use it for your car’s radiator. Mineral buildup from tap water can decrease the lifespan of the radiator in your vehicle, but using water from your dehumidifier can avoid that problem. Simply mix the dehumidified water with antifreeze in the appropriate ratio and top off the coolant tank like a pro.
