Whynter ARC-14S

Cools 500 sq. ft.

The Whynter air conditioner uses two hoses to cool down large areas down to 61 degrees Fahrenheit quickly. Temperatures and program settings can be controlled from the digital panel or with the included remote.


  • Very good at cooling
  • Digital controls
  • No collection bucket


  • Large and bulky

This Whynter air conditioner is eco-friendly because it's lead-free and uses CFC-free refrigerant. It collects over 100 pints, or 12.5 gallons, of moisture from the air each day and recycles it to both cool your home quicker and eliminate the need to empty a collection bucket. It comes with a storage bag to keep it clean in between uses. This unit is rather large and bulky and can be difficult to move around. It is on caster wheels to help.

Honeywell MO08CEDWK6 9

Cools 400 sq. ft.

This portable air conditioner filters dust and small particles out of the air as it cools down your room. It also works as a dehumidifier making it a good choice for humid areas.


  • Air filter
  • Built-in dehumidifier
  • Bucket-less


  • Drain system needs set up for some functions

The Honeywell ac unit features three fan speeds and a timer that lets you keep control of your home's energy use. You can control the air conditioner with the included remote and wash the dust filter to reuse over and over. The unit will let you know when it's time to change or clean the filter. The built-in dehumidifier will draw up to 44 pints (5.5 gallons) of moisture from the air throughout the day, which helps in the cooling process. There isn't a collection bucket, but you will need to set up the drain system if you use the dehumidifier setting.

Best for small areas

Black + Decker air conditioner

Cools 150 sq ft

This Black + Decker air conditioner runs really quiet, so it's great in bedrooms where it won't disturb you while sleeping. It can be used as a fan, or dehumidifier, too.


  • Fan and dehumidifier modes
  • Good for apartments and dorms


  • Struggles in large spaces

This air conditioner is small, so it will only cool about 150 sq. ft. This makes it perfect for dorms, apartments, and offices. The remote control and digital display panels let you set the temperature down to 65 degrees Fahrenheit, and set a time up to 24 hours. The hose is small - under 5ft - but it comes with the adapter you need to attach to a window for optimal use.

Best smart unit

Midea smart air conditioner

Cools 375 sq ft

Connect this air conditioner to your smart home device, and you don't have to lift a finger to turn it on, set the time, or adjust the temperature.


  • Connects to smart home devices
  • Filters dust and pet hair


  • Adhesive sticks to windows

The Midea air conditioner works with both Amazon Alexa and Google Assistant. It can be used as a dehumidifier or as a floor fan, too. It cools down to 62 degrees Fahrenheit and has a 24-hour timer you can set. The filter will snatch dust and pet hair out of the air as it cools, and the filter is washable and reusable. The hose is mounted to your window using the included kit and foam adhesive. The adhesive does tend to stick to the window once the unit is removed and needs a special removal technique in order to avoid damage to your window.

Keep it cool

When looking to buy a portable air conditioning unit, there are some key considerations you need to make, as well as some jargon you need to get to grips with. Here's what you need to look for before you buy a portable AC unit.

Before choosing a portable air conditioner, get an idea of how big the room is and where the unit will be placed. The average size of a living room is 216 square feet while a bedroom is about 132 square feet and a kitchen is between 240 and 360 square feet. Knowing this will eliminate several air conditioning models based on their inability to cool your home. 

BTU stands for British Thermal Unit and is basically a means to measure heat. Air conditioners use BTU to measure how much heat an air conditioning unit can add or remove from a room in the space of an hour. The higher the BTU rating, the quicker the unit will remove the warm air. 

Hose length is an important consideration before buying a portable air conditioner. All portable air conditioners need to be vented outside through a window. If you have furniture in front of the window, a longer hose is needed to be able to vent heated air outside.

Look at the space you have available and where you want to place your portable AC unit. Measure this distance to make sure the hose is long enough. We would recommend portable AC units with a hose length of 5 feet or more for maximum flexibility. 

Remember, portable AC units are noisy. They use motorized fans and compressors that create a flow of air. If you are looking for a quieter unit for the bedroom or something that you can hear the television over, we recommend you check the decibel levels before buying. 

Our recommendations

The Whynter ARC-14SH is the best and most flexible option because it is efficient enough to cool down most areas, including a studio apartment. It works in both humid and arid environments and will recycle moisture pulled from the air to help cool the air circulating through it. This means there isn't a collection bucket that needs to be emptied. You can set the thermostat down to 61 degrees Fahrenheit, but this unit can also be used as a heater. Settings can be controlled from the digital panel on the air conditioner or with the included remote control. The Whynter ARC-14SH is pretty big, weighing 80 pounds, and has a high price tag. But the amount of flexibility and the efficiency of its cooling, and heating, capabilities are worth the cost.

For a more budget-friendly option, check out the Honeywell MO08CEDWK6 9. It works similarly to the Whynter ARC-14SH, including using a bucket-less design. It filters the air and can be used as a dehumidifier, too. it only has a single hose instead of two, like the Whynter model, but still does a decent job cooling up to 400 sq. ft. of space.
