Can Dogs Drink Air Conditioner Water?

Well, it is unsafe for their health.

The AC water is extracted from the air that is present inside your room and we know it very well that the air can be polluted. So, The AC water can also contain harmful toxins, heavy metals, and pollutants.

Provided there isn’t any oil, solvents, or other toxic stuff in the AC /pipes, you may say it should be drinkable and it will essentially be distilled water anyway. Most dogs drink from puddles which are far from clean. They have really tough digestive systems. You may also realize that when outside, they may drink worse, but that worse can sometimes kill them (antifreeze etc.).

However, if your dog doesn’t have a tough digestive system then your dog will get seriously ill.

What Is The Water That Comes Out Of The AC?

First of all, you need to understand the water condition that comes out of your air conditioner. The reason why air conditioners give out water has to do with how air conditioners work.

Your air conditioner unit performs cooling by a system called refrigeration. It has two coils; one is kept hot while the other one is kept cold. Some of this water will evaporate again to cool the coils whereas the rest of the water will move out of the air conditioner. The cooling coils also extract moisture from the air. Now when that cold air condenses, the water starts wringing out of it.

The chemicals present inside the coil of your AC continuously evaporate and condense. This, in turn, cools the coil. When the coil gets cooled, the air blowing above it also gets cooled.

The reason behind this is that the AC water is extracted from the air in your room. Therefore, the water that comes out of your AC is due to the cooling of your air conditioner.

That air usually contains harmful toxins, pollutants, heavy metals, etc. So, the AC water may also contain traces of all those trivial yet dangerous harmful particles present in the air. There are reports of many bacterial pathogens associated with things like drain pans, including Legionella, a bacterial pathogen with significant adverse health consequences (the disease caused by this pathogen is called Legionnaires disease). 

Moreover, the water runs through aluminum fins and is filled with all kinds of pollution from that as well as the dust from the air which even a clean filter will not stop at all. It is definitely not distilled! And also, the insides of air conditioners are a breeding ground for molds, bacteria, and slimes. The air conditioner water can easily contain these harmful bacteria, molds, slimes, and other dangerous germs.

If you drink such water then it will not only upset your digestive system aka your stomach but also make you vulnerable to plenty of other serious diseases. So, in simple words, it is recommended not to drink air conditioner water as it can make you sick.

So, the condensed water from air conditioners is not safe to drink.
