Having a working air conditioner in your house or office can be a huge advantage since it’ll give you full control over your indoor climate. For most people, the problem normally comes about when deciding what the perfect AC unit for their home should be. There’s the option of going for a portable air conditioner, a window unit, a mini split system or even a central AC. If you’d prefer to be able to move the AC unit around, then we’d recommend going for a portable air conditioner. The Costway 8000 BTU portable air conditioner for example is pretty compact in size, and with a cooling coverage of about 230 square feet, we think its worth considering especially if you’re shopping around for the best portable air conditioner for RV.

Why We Like It – Costway Portable Air Conditioner

Only available in the color white, the Costway Portable Air Conditioner is an easy to use AC that comes with its own window kit for easier installation, and will work best in a room that’s as big as 250 sq ft. The air conditioner offers cooling, dehumidification & fan functions, making it a worthwhile purchase that’s capable of different things.

  • Includes a window kit
  • Dehumidifying capacity of 50 pints per day
  • 3 in 1 functioning
  • No check filter indicator


The Costway portable air conditioner unit isn’t as feature packed as the Ontel Arctic Air Ultra, but it does come with some other worthwhile features such a dehumidifying function, as well as a fan. The portable AC unit however has only 2 options for its fan speed (high and low), but it features a wide adjustable range of temperature (18 to 30 degrees). On its front, you will notice a shutter there, and it allows you to change the wind direction either vertically or horizontally.

Energy Efficiency

Rising energy costs is one of the main reasons why a lot of people tend to consider the energy consumption level of an AC unit before they pick one. Because of its low cooling power, the Costway portable air conditioner doesn’t really require that much energy to run, but unlike the LG LP0817WSR 115v Portable Air Conditioner, it does come with a sleep mode that you can activate at night for it to use less energy as it does.


The Costway portable air conditioner offers a slide out filter that’s very easy to handle, so you shouldn’t really have any problems taking it out for washing or replacement. The filter is a basic dust filter that prevents any dust from getting into the AC unit, and there’s unfortunately no activated carbon filter like you’d find in the Whynter ARC 122DS Elite. To ensure that the Costway air conditioning unit works great all through, we recommend washing the filter twice a month, and all you need to do is hold it under a running water faucet.


Like a majority of portable air conditioners, the Costway AC comes backed by a 1 year warranty, where both parts and labour happen to be covered. If you get your new unit and discover that it’s got some underlying problems, please try reaching out to Costway’s customer service team, and they’ll be ready and willing to assist. With proper use and good maintenance most air conditioners last almost 10 years before they start coming up with problems, so you’ll be in pretty good ground with the Costway AC.


According to many of its customer reviews, the Costway Portable Air Conditioner offers pretty quiet operation. You’ll be able to sleep at night without much distraction, and also use its remote control to make adjustments without necessarily walking up to the unit. It’s dehumidifier function is capable of taking out up to 50 pints per day from the air, and it’s also got an extendable drain hose that’s pretty easy to install.

Costway Portable Air Conditioner Wrap Up

The Costway Portable Air Conditioner is a decent AC unit to start out with. It’s got all the major features you could want, and compared to many related products, it’s also a lot more affordable.
