So, what is the difference between a portable air conditioner and a portable evaporative cooler?
Yes, they are both portable, and they are both coolers, but a portable AC and an evaporative cooler are two completely different devices.
Coolers that are labeled portable only, need to have a hose that can transfer the hot air from inside to outdoors. These air conditioners use compressors and refrigerants to cool the air and to remove it from the room or area.
Coolers that are labeled ventless do not need to use such a hose and use a water tank and the natural process of evaporation to cool the warm air and emit it back out.
The ventless portable air conditioners are actually the more portable type, as they do not need to be connected to a vent, window, or other.
They use much less electrical power than the AC units and are more eco-friendly than them.
Which type will suit you best?
Choosing whether or not a ventless portable air conditioner is suitable for you largely depends on where you live. Namely, on the temperatures and humidity levels in your region.
To work properly, ventless evaporation coolers need the air to be hot and dry. In fact, they work best when the humidity levels are lower than 60% because they cool the air by adding moisture to it. These devices work well outdoors and indoors, but inside they do need to have access to fresh air (via an open window or door) so that they do not make the air too oversaturated with moisture.
As for the portable AC units, they can do well in both dry and in humid climates, because they cool the air via refrigerants and compressors.
So, no matter what your opinion is about which unit is more portable, which is more energy-efficient, and which is more eco-friendly, you really need to keep in mind the climate in your area before choosing to buy a portable evaporative air cooler or an AC unit.
The ventless portable air conditioners work best in the Midwest and Southwest US areas.
How do ventless portable air conditioners work?
Evaporative air coolers are the older type of coolers and use the natural process of evaporation to cool the air inside and outside.
They suck in the hot air from the room or environment, drive it through a cooling media, and then deliver it back into the air in the form of vapor – cooler and with added moisture.
These units use water and in some cases ice for cooling, rather than compressors and chemical refrigerants.
This makes them less expensive to buy, less expensive to maintain, and more energy-efficient and eco-friendly than portable air conditioners.
Plus, they can work both indoors and outside and can provide fresher air, as well as work as fans and humidifiers as well.
In fact, many of these appliances can be used as humidifiers even when the temperatures are not so hot.
The main drawback of the ventless evaporative air coolers have is that they are not suitable for all kinds of climates, especially in humid ones.
Features to look for in a ventless portable air conditioner
Ease of installation
You need to ask yourselves the following questions – How easy it is to install the unit? Does it need assembling? Does it actually need to be installed at all?
The portable evaporative air coolers we have picked for you are all “plug and play” devices. You just need to take them out of the box, fill their tanks with water or in some cases add some ice, plug them in, and switch them on.
Many of the ventless evaporative coolers on our list are built to withstand strong sun, UV rays, and outdoor weather because they are meant to be used both indoors and outside.
If you need a cooling device that you will be using in your home only, then you may opt for the more decorative and lighter models.
Still, please note that the coolers we have picked by Cool-Space come with lifetime warranties for their roto-molded housing which is something worth considering when investing in a cooling unit, especially if you are looking forward to making a long-term investment.
Obviously, if you are reading this article, you are looking for a portable air cooler, so keep in mind the dimensions and weight of the unit, as well as how maneuverable and easy to move from one room or area to another it is.
All of our picks have castor wheels which allow for easy maneuverability, but the dimensions of the different appliances differ quite a lot.
So, think about how often and where you are planning on using your ventless portable air conditioner, and how often you plan on moving it so that you get one that you can use as intended without too much effort.
Just like with a regular air conditioner, you need to choose a ventless portable cooler in accordance with the room or area you are planning on using it for.
Some of the cooling appliances on our list are very compact and are suitable for cooling small and medium-sized rooms, while others have larger coverage, and can cool significant areas no matter whether they are located indoors or outdoors.
When you think about the capacity, you should think about the capacity of the water tank of the device as well. Here are some of the questions you need to ask yourself:
How often will you need to refill it? How easy is it to refill and drain it? Does it have an option for a connection to a continuous water source for unattended use? Does it have an alarm, indicator or auto shut off function when it is out of water?
Type of operation
Some of the vented portable air conditioners have a vent-only operation that only cools the air without humidifying it.
Others have two or more different speed settings and can be used for dry and moist cooling.
Some of our top picks can operate as fans, coolers and as humidifiers together and separately, which is another option to consider when shopping for a ventless portable air conditioner for your needs and for your climate.
Since users are looking for evaporative air coolers either for ecological reasons or for saving money for energy bills, we have chosen the most energy-efficient of all ventless portable air conditioners for you.
These appliances use minimal amounts of electricity to operate and still provide satisfactory results if you are using them in the right climate and the right space.
Whichever one of these excellent quality ventless evaporative air coolers you choose, you can be pretty sure that you will be spending much less money on electricity bills than if you choose a portable air conditioner.
Also, you will not be buying a device that uses harmful refrigerant, so you will be helping the environment as well.
The price of the ventless portable air coolers is much lower as compared to that of the air conditioners of the same size and capacity. The reason is that the former do not have compressors and refrigerants, and rely on the much simpler natural process of evaporation to cool down the air.
You should set a budget for your future ventless portable air conditioner, and look for the device which comes closest to the price you have set for it, and at the same time has the perfect features for you.
No matter how expensive the evaporative cooler of your choice is, you can be pretty sure that it will pay back in time, because of the low power consumption, the lack of need of filter and refrigerant replacement and refilling and other ongoing costs associated with portable air conditioners.
Pros and cons of ventless portable air conditioners
