What exactly is BTU?

BTU is an abbreviation for British Thermal Unit and is used as the standard unit for measurement of the majority of cooling and heating systems. It stands for the amount of energy that a unit needs to change temperature one degree up or down (in Fahrenheit) of 16 ounces of water.

The larger the BTU number – the larger the area in which the unit can cool. Higher BTUs, though mean larger and bulkier devices. Also, higher BTU levels usually lead to louder noise during the cooling or heating operation of the device, since a larger compressor is needed. Also, this leads to more energy consumption.

In other words, units that have higher BTUs are more suitable for larger areas where the noise is not so noticeable, such as in an office, a working area, or a server space.

You may want to go for a unit with a lower BTU for bedrooms or other living spaces if you are sensitive to loud noises.

Do you need a humidifier or a dehumidifier?

Most of the top picks for portable air conditioners on this list come with dehumidifiers because they often pull the moisture out of the air and use it for the cooling process.

A living space with too much humidity can lead to discomfort, including excessive sweating and a feeling of fatigue. It also can promote the growth of mold, which released harmful spores into the air, which are particularly bad for those of you with allergies, asthma, and other respiratory problems.

On the other hand, living in a dry climate is also not good for your health and wellbeing. You need some moisture in the air to keep your skin moisturized and in order to breathe properly. There are some evaporative air coolers on the market which work as humidifiers as well because they add moisture to the air during the cooling process based on water evaporation.

The ideal humidity level in your home should be lower than 60%, so make sure you measure the current humidity levels before choosing whether to buy a unit that works as a dehumidifier or a humidifier.

Remember that evaporative air coolers are not as efficient in cooling the air in places where the humidity level is high (60% or more).

Measuring the room size to pick the most suitable air conditioner

Before choosing the most suitable portable air conditioner, you must measure the room or area where you plan to use it. If the room is very large, a smaller and less powerful unit will not have the cooling effect which you expect. Also, if the unit is too powerful for a small area, it is very likely that it will reduce the temperatures to uncomfortable levels.

This is why you should always measure your room in square feet prior to buying a portable cooling or air conditioning unit. All you need to do is measure the length and width of the room and multiply them. If the living space is not a perfect rectangle or square, you can break the floor down to squares or triangles in order to get the correct square footage.

Once you know the size of the room, picking the most appropriate portable air conditioner will be much easier.

FAQs that can help you pick the best portable air conditioner

What makes a portable AC better than a split or window AC?

The first answer is portability. You can easily move your portable AC from one room to another, unlike the fixed window or split air conditioners.

The second answer is cost. Portable ACs are much cheaper than split or window air conditioners. Plus, you don’t need to pay for installation, or for installing windows or split ACs in every living space of the house. Also, they are much more power-efficient than central air conditioning.

Are portable air conditioners power efficient?

Portable air conditioners can be used for cooling single rooms or limited areas, instead of paying for the power needed to cool the entire house via a central AC. Also, you can use them in the fan-only mode when the temperatures fall, which, too, will save you tons of money.

Evaporative air coolers are especially power-saving, as they do not require a compressor in order to cool the ambient temperature in the living area.

Are portable ACs noisier than window or split ACs?

Unfortunately, the answer is yes. This is because they are located entirely in the room, unlike window or split units where the cooling unit is outside.

The noise from the good quality portable air conditioners is not so bothersome, though. Some new models have quiet modes and operate at 48 dB.

If you are sensitive to noise, opt for a portable one that has a noise reduction feature, or use a rubber stand to place the unit in order to reduce the vibrations and thus the noise during operation.

How much maintenance is required?

Portable ACs do require some maintenance, but it is not as costly as that required for fixed window or split air conditioners.

The units which have dehumidifiers and do not have an auto-evaporative feature require that the water tank or tray is cleared out on a regular basis. Thankfully, all of these units in this list have useful indicators to warn you when it is time to pour out the accumulated water and will shut off automatically in case you fail to remove the water.

Most of our top picks have the self-evaporation feature, so this is not something that you should be worried about.

The filters of the portable ACs also need to be cleaned from all the dust and other airborne debris. This though can be done every few months, and with these particular models, all you need to do is remove the filter and wash it thoroughly before reinstalling it back.

Choosing between single and dual hose units?

In general, portable air conditioners with a single hose are lighter and more compact than those with a dual hose system. They are, however less efficient than the ones with two hoses due to the negative pressure which allows for hot air to leak through any gaps in the room.

Dual hose units use separate hoses for the intake and exhaust of the air, so the air pressure in the living area is not affected. This makes them more efficient for consistent cooling than single-hose portable air conditioners.


As you can see, choosing the best and most suitable portable air conditioner is not the easiest task. You need to consider several important factors, including the size of the room, the functionality you expect, the BTU power, the noise level, the portability and mobility of the unit, as well as the installation and maintenance requirements. Also, you need to consider other factors such as ease of use, the type of control or remote control which the cooling device has, and whether you need a humidifier or a dehumidifier. The latter depends on the climate conditions of the area you live in, as well as on the humidity levels in your home.

If you are looking for some added useful features, pick one of the portable ACs which have useful programmable timers, a sleep mode, an auto shut off mode, or why not a smart portable air conditioner that connects itself to your home Wi-Fi for easy control and monitoring.

For people suffering from dust, pet dander, pollen, or other allergies,  always look for an air conditioner that has efficient air filters which will help clear the air from allergens and will keep you comfortable and allergy-free. This is also essential if you or a family member suffers from allergies or has other problems with the respiratory system.

The design and the size of the unit are also pertinent to most people, so make sure you pick the one which will fit your interior and available space. Most of the models have comfortable handles and added wheels for added mobility, which you should keep in mind as well, especially if you are planning on moving the unit around or keeping it in storage whenever it is not in use.

We have described in detail what to expect from each and every one of these units.

Hopefully, our comprehensive reviews which include all the basic features, and the pros and cons of the leading portable air conditioners and evaporative air coolers will help the task of picking the most appropriate portable cooling device to serve your needs and meet your expectations much easier.

Good luck and enjoy the multiple benefits of owning a portable air conditioner!
