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, which is why it is important to ensure that it whispers quietly.

In general, most ventless air conditioners are noisy, and this is something you might not like. 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, and this can generate 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 out there all claim to be reliable. However, that is not always the case because some of the manufacturers are only out for profit. One guaranteed way to ensure that you are buying a reliable ventless air cooler is by getting it from a recognized HVAC company.

Therefore, getting it from a reputable company will always be the best thing to do. However, the popular HVAC companies are not always in the business of producing ventless air conditioners. They usually focus on producing ones with vents.

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


All the things we’ve mentioned above are equally important, but most of all is the convenience factor. One thing you should note about most portable AC units is that they don’t always have multiple features like auto restart, programmable timer, digital display, and remote control. In general, these features help in making the operation a lot easier. However, it doesn’t necessarily mean that without these features the device won’t be easy to use.

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, there are improved ventless air conditioners that utilize evaporative technology to recycle excess moisture. Such devices draw out the moist air and condense the water to cool the hot coils before evaporating it. 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.


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 we mentioned in this review, we consider the evaCHILL Personal Air Cooler as the best choice, especially if you want to cool your personal space.
