If you don’t want to empty your cooling unit’s full water tray, consider using one of the best fully self-evaporating best portable air conditioners.

These types of units don’t need to be drained frequently. They have an inbuilt condensation exhaust hose that expels the moisture during the cooling and dehumidification process. This water vapor is released to the outside together with the hot exhaust air through a single hose.

There are many benefits to choosing a self evaporating portable air conditioner, which we have discussed in the next section. However, you have to consider a few factors before you can pick an ideal unit.

If you don’t want to go through all the hassle, I have narrowed down the list to five products that will function effectively depending on the size of your room and the amount of warm air provided.

What is Self Evaporating Portable Air Conditioner?

5 Best Fully Self-Evaporating Portable Air Conditioners 2022 (6)

Aside from just blowing cool air into a room, air conditioners also blow moisture out of a room and into the air conditioning unit.

The tricky part is that this moisture has to go somewhere. Self-evaporating air conditioners are quickly becoming popular due to their added feature of automatically removing moisture for you without a hassle.

The benefit of using a self evaporating portable air conditioner is that it eliminates the need to manually empty its water collection tray, which is usually necessary with the traditional air conditioners. Self-evaporating ACs are also called “no-drip units” since water doesn’t drip from their rear side.

This happens because the AC unit recycles half of the condensed water, which is then used to cool down the inner cooling coils and allows the unit to run efficiently.

How Does Self Evaporating Portable Air Conditioner Work?

Unlike central air conditioners, the self-evaporating portable air conditioner works quite differently. First, they condense the excess moisture from the cool air during the refrigeration and then cycle it through the cooling system to provide more cooling efficiency.

After that is done, the unit then re-evaporates or expels this moisture into its hot air exhaust vent hose, thereby dispersing the remaining moisture outside with hot air, which is the natural by-product of this process.

What this means for the user is that you won’t need to drain anything into the container since most of the moisture formed during the cooling process has been exhausted out of the room. Additionally, self-evaporating air conditioners are energy-efficient.

Do you Need a Fully-Evaporative Portable Air Conditioner?

The answer to this question highly depends on your preferences. If you always have to keep on emptying the water-catcher tray of your AC unit, and this drives you nuts, then it’s high time you get a fully-evaporative portable air conditioner.

This type of air conditioner will also help you stay cool and comfortable during the hot summer season. With an evaporative air conditioner, you won’t need to drain the hoses or the water-catching tray of your AC unit.

It is an ultra-cool type of air conditioner that will efficiently re-evaporate all the moisture that it has condensed from the air. And expel it through the vent hose to the outside.

Do You Have to Empty Water from a Portable Air Conditioner?

Unfortunately, most portable ac units and traditional air conditioners need to be drained regularly. This can be a hassle sometimes, but it has to be done one way or the other. This is why people nowadays are opting for self-evaporating portable air conditioners.

Traditional air conditioners need to be emptied because when you’re using them, the humid air isn’t blown back out the way cold air needs to be sent out of the room to create ventilation.

The disadvantage of this lack of ventilation is that you’ll have an AC that blows out both cold and hot air, which ends up defeating the entire process. That is why you have to constantly empty water from a portable air conditioner.

How Often Do You Have to Empty a Portable Air Conditioner?

The recommended period you need to take to empty a portable ac is approximately 8 hours. We are talking about the manual removal of water from the water-catching tray of your air conditioner. To do this, you need to have a drain pan or bucket, or you can also move your AC to a convenient place to drain it in a sink.

The process involves locating the drain plug on the back of your AC or side and then removing it together with the rubber stopper. This will completely drain the water tank.

What Happens if You Don’t Drain Your Portable Air Conditioner?

Most portable air conditioners need to be drained water properly after long use or every 8 hours of continuous working. If you don’t vent your AC unit outside or into another room, the hot air will remain trapped inside the space.

The less humidity there is in floor space or room, the cooler it will feel. When you fail to drain your portable air conditioner, the moisture will continue to build up, thereby neutralizing your AC’s powerful cooling effect.

Benefits of Self Evaporating Portable Air Conditioners

Here are some of the benefits of self-evaporating portable air conditioners:

  • They reuse condensed moisture, which eliminates the need to drain any water collected. Therefore, you won’t need to keep on venting your AC unit every 8 hours like you have to with traditional air conditioners.
  • Less maintenance:Since they don’t require regular water draining, self-evaporating ACs are easy to use and maintain.
  • Energy-efficient:Another notable benefit of self-evaporating portable air conditioners is that they don’t consume a lot of electricity. They are convenient and efficient to use in your home.
  • Easy to install and use:Self-evaporating portable air conditioners are easy to install and use, which means anyone can use them in their home or commercial space.
