Air conditioning is a very familiar device in every household. Surely, everyone knows that when the air conditioner is operating, there is a certain amount of water condensing and flowing out through the drain pipe. Many people think that the waste water from this air conditioner is not clean so they pour it away. In fact, you can collect it for use in some household purposes, both to save water and to overcome water shortages if your area is experiencing a water shortage.
Why is there water flowing from the air conditioner?
When the air conditioner operates, the room will quickly reach the temperature set by the user. The dry and airy space also means that a certain amount of water vapor in the air will condense to form water droplets. Then, the water will flow out through the drainage pipe. Usually, the amount of water flowing out from the air conditioner during operation is not too much. If your home’s air conditioner is expelling too much water, then there may be a malfunction.

In reality, the water flowing out from the air conditioner is pure so it can be boiled and used with the condition that the air filter and the air duct are regularly cleaned. However, during use, it is unavoidable for the ducts, copper pipes, and other parts to accumulate dust, moss, and many harmful bacteria. This causes the water flowing out from the air conditioner to contain impurities, dust, and harmful bacteria, making the water no longer clean. If it is not treated properly and still used, it can be harmful to health.
Some tasks that can make use of air conditioner waste water
+ Watering plants
The condensate water from the air conditioner can be used for watering plants both indoors and outdoors. The condensed water is drawn from the outside air and therefore does not contain chlorine or any other minerals. You can fill a watering can and connect it to a rainwater collection system, so you can directly drain the water into your garden. Or you can simply collect it in a bucket or basin and use it for watering the garden.
However, the waste water from the air conditioner contains a high concentration of salts and minerals. Usually, it is not enough to harm your plants, but if there is an unusually high concentration of salts and minerals, you should reconsider using it for watering plants.
+ Fish farming
The waste water from the air conditioner can be used for water features such as fountains, or fish farming. With the air conditioner waste water, you can fill a fountain as well as a fish pond. You can also use this water as part of an irrigation system for your pond or other water features.

+ Cleaning the house
There is nothing wrong with using water from the air conditioner to clean the house. In a bucket, you can add detergent or soap, and with a mop, you can go outside and start cleaning your house. You can even use it to clean your car if you have enough.
+ Cleaning jewelry
If the jewelry in your house is rusty or discolored, you can use the condensate water from the air conditioner to clean it. The reason is that the sodium fluoride in the water can brighten and remove dust from the surface of the jewelry.
Before cleaning the jewelry, it is best to soak the jewelry in the waste water from the air conditioner for about 6 hours. Then, use a cotton swab to thoroughly clean it. After drying, the jewelry will be much brighter than before, especially silver jewelry which will be noticeably whiter.
