A ventless air conditioner can be a lifesaver for many reasons. It is often portable, takes less space than a conventional AC unit, requires little to zero installation, and is often more pleasant to look at. Also, these units are energy efficient and will emit very little noise. They are designed to increase comfort, and you won't have to worry about filling holes in the wall after installation.

In this article, we'll focus on the best portable air conditioners without a hose available on the market. Buying one can be tricky, so we have also provided a buyer guide to help you make the right decision.

We would also like to precise that a portable AC unit without a hose, which uses air conditioning as a cooling method, doesn't exist. It would simply break the second law of physics! An air conditioner needs a vent (exhaust) to eliminate the hot air. This is why we will use 'air conditioner' as an umbrella term in this article, and then we will dive into the cooling methods of each device in particular.

What Is a Ventless Air Conditioner?

There are two types of ventless ac units:

  • Standard Air Conditioner: Does not need a connection to ventilation contrary to split systems. Most likely, it is based on a traditional fan, with add-ons, oscillation, and other perks to make the cooling more efficient.
  • Evaporative Cooler: Despite the name, most ventless evaporative air conditioners are actually air coolers. They work due to the principle of water evaporation. The evaporative cooler will reduce your personal space's temperature and make you feel comfortable.

Both of these types are primarily portable and can be used to freshen up a small room or your personal space.

What to Look for When Buying an Air Conditioner Without a Vent

Buying a ventless air conditioner can be a daunting task, especially when you do not know what’s obtainable. There are so many options available on the market, and if you go to get a ventless air conditioner without knowing what to look for, you’ll only end up confused.

The importance and benefits of ventless air conditioners cannot be overemphasized, which is why you need to be thorough when you choose the best ventless portable AC.

Cooling off with ventless air conditioners is awesome, and here are the key things you should look for when buying an air conditioner without vents:

High Airflow

The airflow of the air conditioner should be the first feature you look for when buying one. In general, when the airflow is higher, the air conditioner will work better. Also, ventless air conditioners have different airflow rates. Another reason why you should consider an air conditioner with a high airflow rate is that it will cool faster and more effectively.

Low Noise Levels

The reason for buying a ventless air conditioner is to make your personal space more comfortable. However, this will not be possible if the air conditioner you get is noisy, so it is crucial to ensure that it whispers.

Most ventless air conditioners are generally noisy, which can be a bummer. The good thing is that most manufacturers try to strike a balance between the level of noise and the airflow. It is important to note that ventless air coolers can create over 1000 CFR airflow, generating as much as 70+ dB of sound. From the six products we have provided above, you'll find some that are quiet and others that whisper quiet. It all depends on what you want.


This should be your top priority when buying a ventless air conditioner. Most of the products you'll find there all claim to be reliable. However, that is not always the case because some manufacturers are only out for profit. One guaranteed way to ensure that you buy a reliable ventless air cooler is by getting it from a recognized company with a history of presence on the market.

If you are confused about what brand to get, you can consider any of the products we have mentioned above.



All the above-mentioned things are equally important, but the convenience factor comes first. One thing you should note about most portable AC units is that some of them don't have features like restart, programmable timer, digital display, and remote control.

If you need a model with remote control, you can check out the evaporative air cooler evaSMART, which is operated remotely and is compatible with smart homes.

In general, these features help in making the operation a lot easier. However, it doesn't necessarily mean that the device won't be accessible without these features.

Also, the method the unit uses to dispose of moisture is another thing you might want to consider. Some of the portable units available utilize an external draining hose, while others make use of an internal container that you must empty regularly. With technological innovations, improved ventless air conditioners utilize evaporative technology to recycle excess moisture. Such devices draw out the moist air and condense the water to cool the hot coils before evaporation. With this, you wouldn't need a water bucket or hose to empty the unit.

The choice is yours to make, whether you want a unit with a hose, an internal bucket, or a unit that recycles excess moisture.


The last thing you might want to consider when buying a ventless air conditioner is your budget. You need to be sure that the cost is within your budget and that you are getting value for your money. Some ventless air conditioners are expensive, while others are budget-friendly. Factors that determine the price of a ventless air conditioner include size, design, and overall capacity of the unit.

Water Tank Capacity

The cooling effect of the ventless evaporative air cooler is generated with cold water. Also, you'll need a larger tank capacity to enjoy the cooling effect for an extended period. Therefore, you might consider this when buying the best ventless air conditioner.


From all we've mentioned above, you can see that ventless AC units are perfect for rooms of any size. With these devices, you can enjoy cool temperatures during summer and sufficient humidity in winter. Of all the products mentioned in this review, we consider the evaCHILL Personal Air Cooler the best choice, especially if you want to cool your personal space.
