How We Ranked

Portable Air conditioners all promise similar benefits to each other. They all claim to lower air temperatures in smaller spices with a small, portable design.

Unfortunately, not all of these units live up to their promise. Some spread water vapor around your house without cooling the house. Others are poorly designed and will break after a few months.

To separate the best and worst portable air cooling units, we ranked the best portable ACs by using the following metrics:

Cooling effectiveness: Some portable air conditioners are poorly designed and just won’t work very well. Others can create surprisingly chill temperatures. At the end of the day, this is what matters the most, which is why we used cooling effectiveness as the biggest ranking factor we used. Since you’re buying an air conditioner to create cooler temperatures, we wanted the best unites to help you achieve these goals.

Humidification effectiveness: Many people buy their portable air conditioners, not just to cool the temperatures but also for the humidity. Good portable air conditioners work as both a humidifier and air conditioner rolled into a single convenient unit. This is why the effectiveness of this was taken into account.

Style, design, and aesthetics: Although it certainly isn’t our most important factor, we still considered the style, design, and aesthetics in our rankings. Some of the top portable air conditioners have gone above and beyond to invest in quality design characteristics. Others look boring, bland and don’t look ideal for bedroom décor.

Ease of use: Most portable conditioners can be used by virtually anybody, regardless of your tech skills. With the units we mentioned above, simply fill with water and ice, plug them in, and allow them to run. That’s all you have to do.

Additional features: The main goal of any portable air conditioner should be to cool the room. However, some of the other portable AC units listed above create humidity, filer the air, or even remove bacteria and pathogens from the air using UV light. We took all of these additional features into consideration.

Return policy: For whatever reason, some portable AC units just don’t work very well. If you’re dissatisfied with a unit, you should be able to return it easily. However, some portable AC units have surprisingly restrictive return policies and some companies even make it deliberately difficult to return. All reputable manufacturers should stand by their product and the quality, and therefore make it easy to refund when unsatisfied.

Customization options: You may want different levels of coolness, depending on the time of day and temperature. Some people desire cool temperatures all day long whereas others just want it for when they sleep. We considered all of these customization options in our rankings.

Ice Tray, Water Curtain, and Misting Device: Most portable air conditioners use an ice tray, water curtain, or misting device to create cool vapor. These devices absorb hot, dry air through the back, expelling it through the front as cleaner, cooler air. Some of these devices are simply better and more effective than others.

Value & Price: Some people only want to spend $15 on a portable air conditioner whereas others want to spend $200. We felt it was important to list air conditioners at all price points, allowing you to easily pick the right portable AC that meets your budget. We still however picked the right AC units at each price point to ensure you didn’t get ripped off.

Customer Reviews: It’s always important to get an idea of what actual customers feel about products in question. Although we tested out portable ACs, customers test them in different conditions more often and have a better idea of whether or not a portable AC is legit or not.

Transparency: Some portable air conditioners provide the user manual and everything you need to know about the product. Others refuse to disclose even basic information, all of which is essential to your experience with the product. We took this into consideration when creating our rankings.

Best Places to Use a Portable AC Unit

Portable air cooling units are ideal for use in a variety of different settings. Most people use them in a bedroom, office, or other small space. Others run the units outdoors, creating cooler temperatures in a backyard, tent, or other similar space.

The nice thing is that portable AC units do not typically require direct power. They often have a battery you can charge, making it easy to run the portable AC unit anywhere.

Some of the various places you can place a portable AC include:

Bedrooms

  • Apartments and condos
  • Offices
  • Dorm rooms
  • Smaller homes
  • Outdoor spaces

How do Portable Air Conditioners Work?

Portable air conditioners work in several different ways. The ACs on our rankings use basic technology to create cool temperatures, passing water through a curtain to create cooler vapor. They are primarily designed for smaller spaces, including a small office or bedroom.

Some portable air conditioners are much more advanced and they’re capable of lowering temperatures through a much larger space. Some have up to 12,000 BTUs, for example, and require you to connect to the outside air using a house. Others have a dual-hose design.

When you buy an air conditioner, you get a unit with a refrigerant to cool the air, a compressor to compress the refrigerant, and a fan to move the air. It’s similar to how a standard whole-home air conditioning system works. The unit takes air from the outside world, cools the air using refrigerant, and a compressor, then circulates the air.

They are fine for massive homes but these units also withdraw humidity in the air, creating dry air that can cause dry skin, nosebleeds, and more.

Portable AC systems work much differently. They add moisture to the air instead of removing it. They can still create cooler temperatures though – just without the need of refrigerant or a compressor.

Here’s the basic process on which portable air conditioners work:

Step 1) The unit draws hot, dry air from one side.

Step 2) The air enters the unit, passing through a water curtain. That water curtain is connected to a hydration chamber and, in many cases, an ice tray. The water curtain is cool and wet.

Step 3) As air passes through the water curtain, it causes the water within the curtain to evaporate. Evaporation requires heat. As the water evaporates, it removes heat from the air, creating cooler and cleaner temperatures.

Step 4) A fan blows the cool, moister air out the other end of the device, spreading lower temperatures throughout your room or home.

Advantages of Portable Air Conditioners

Portable air conditioners have several advantages over other types of air cooling systems, including the following:

#1 – They’re more affordable: A whole-home HVAC system can cost you hundreds of dollars per month to cool your house. Portable AC units can cost you a fraction of the cost because you only need to cool the rooms you use. Plus, the units are so much small and use less energy than other cooling options. Instead of plugging the unit into an outlet, there’s a charging port an a USB outlet to use.

#2 – Temperature Customization: Some portable aid conditions have a thermostat whilst others have a temperature gauge with different generic temperature levels. Even if you can’t really set a specific temperature with each portable AC, you can still set how cold or hot you want it to be – to a certain degree.

#3 – Add humidity instead of eliminating it: Most home-HVAC systems remove the humidity from the air, leaving the air dry. This is why you may experience dry, cracked skin as a result of using an air conditioner too long. Portable air conditioners help keep air somewhat moist so that you can enjoy cooler, moist air all summer long.

#4 – Acts as an air filter: Many of the portable air conditioners on our list are fitted with additional filers to remove bacteria, toxins, VOCs, and other harmful compounds. Sometimes these filters are UV filters whereas others are physical filters. Either way these filters help ensure you don’t consume harmful compounds.

#5 –Easy for anybody to operate: Even if you have limited technical skills or experience, you can still easily use a portable AC. As long as you can fill water in a tank or add ice cubes in a ray, you can easily use most portable AC units.

#6 – No installation required: Portable AC units don’t require you to install anything in your home. They come in pre-made, ready to be filled and charged. In fact, you don’t even need to install tubes or pipes out your window.

#7 – No electrical connection needed: Most of the best portable AC units above run off batteries or sometimes micro-USB. That means you can run them virtually anywhere without the need for an electrical outlet nearby.

#8 – Very portable: Portable AC units are small enough you can carry around your home to wherever you desire. You can bring a portable AC unit in your office, in your bedroom, in your kitchen, anywhere. Larger portable AC units even have wheels, allowing you to spread the cool air wherever.

#9 – Affordable: An HVAC system will easily run you $5,000 to $10,000 if not more. Most portable air conditioners are priced around $90, which is more than affordable given their power and effectiveness. If you’re looking for the best of the best, you still will likely spend under $200 for a portable AC.

#10 – Quiet: HVAC systems are often very noisy, potentially keeping you awake with clanking, whirring, and activation or deactivation sounds. Portable air conditioners are not as noisy and are often very quiet. They often have different sound settings, making it easy to choose the level of noise. Either way, they’re much quiet than an HVAC system.

11- They’re effective: Although they may not seem effective, you can keep your house cool surprisingly well with a portable air conditioner. They may not be able to come close to a whole-HVAC system but portable air conditioners can deliver lower temperatures at a cheaper price point.
