There are a million and one reasons to own a portable air conditioner: they are able to cool and dehumidify a room, they’re easy to control, their portability allows them to move around for cooling specific areas in a house/office/building, and about 999,997 other reasons.
The trick is to find the portable air conditioner you really need based on your situation, the extra features you want, and how large of an area you want to blast cold air into.
One of the essential factors to pay attention to is the BTU (British Thermal Unit) which measures the amount of warm air that can be effectively removed from an area in an hour’s time. In general, the higher the BTU, the more effective it is at cooling large rooms.
Here, we’ll be looking at three 10,000 BTU air conditioners with a dehumidifier by Costway – a California-based home appliance and furniture retail store.

COSTWAY 10000 BTU & Dehumidifier
This 10,000 BTU air conditioning unit by Costway does more than just blast cold air into a room. It can also dehumidify a room of warm, moist air.
On fan mode, it promotes air circulation; and its sleep mode increases room temperature gradually every hour. This is what makes it so suitable for small places like dorm rooms or personal offices.
This is a compact air conditioning unit (12 x 13.3 x 28.1 inches) with wheels. Because of the wheels moving the unit between spaces is extremely easy to do. But don’t be fooled by its compact design and light weight, it is still a bulky appliance. It’s a powerful device that can adequately cool medium- to large-sized rooms.
Costway recommends using this portable AC in areas of 200 square feet, but the 10,000 BTU allows for proper cooling in rooms as large as 450 square feet.
The largest complaint people have about this unit is the lack of a drain hose. You’ll either have to buy a drain hose separately to dispose of water droplets that come from the air conditioner, or you’ll have to place a small tray below the drain vent.
If you forget to empty the drain tray, then you’ll be left with long-term water damage on your floors. Some have also complained about loud noises coming from the unit, but normally this air conditioner doesn’t produce noises louder than the traditional wall units.
At the end of the day, it’s a versatile portable air conditioning unit with more features than you’d expect from its compact design. Despite the lack of a drain hose and unrealistic expectations of quietness, this unit should perform as well as other air conditioning units out there on the market.
COSTWAY 10000 BTU 
This Costway portable air conditioner  performs a variety of tasks. Aside from effectively and efficiently cooling down areas of up to 200 square feet (Costway’s recommended room size), this unit also features a dehumidifier to get rid of excess moisture, a fan mode which helps with air circulation, and sleep mode which gradually raises a room’s temperature.
Not only is it portable, but it’s also compact so it hardly takes up any space (13 x 12 x 24.5 inches). It’s the ideal piece for dorm rooms and small cabins.
You’ll be surprised at how powerfully this machine works despite its small size. The 10,000 BTU means it works for rooms of up to 450 square feet so it can definitely be used to thoroughly cool large spaces. The fan speeds allow for perfect air circulation to keep rooms in a constant cool temperature.
Not only does it perform well, but it hardly produces any noise, even when the air conditioning mode is on. The noise it does produce is the air blowing, not any mechanical components or fan blades, so it will definitely not distract you while you’re studying or disturb your sleep.
Similar to the previous product, there really isn’t much to complain about with the Costway 10,000 BTU Portable Remote Control AC with Dehumidifier. Its window kit and exhaust hose are easy to set up through any horizontal- or vertical-opening window.
However, a problem that some customers have with this product is that water doesn’t exit through the vent, meaning that you have to babysit the air conditioner to ensure that the water droplets don’t ruin your floor.
The bottom line is that this unit really isn’t much different from the previous Costway portable AC mentioned on this list. They have the same features, portability, remote controllability, and the same problem with leaky drain vents. They only look different.
COSTWAY 10000 BTU [23049-CYPE]
Finally, we have the last Costway portable AC on this list. As you can tell from the name, it’s not much different from the previous models mentioned in this list. The largest differentiating factor is the larger LED display.
The compact size of this portable AC unit doesn’t diminish the power of its air conditioning setting. It can adequately cool a 450-square foot room with its constant stream of cool air.
The fact that this unit rolls on caster wheels means that you can easily guide it to different rooms or places in a large space.
This 10,000 BTU portable AC unit comes with a remote control so you won’t have to manually get up and change the temperature settings or modes. With a click of a button from across the room, you’ll have the unit set to whatever setting you like.
Once again, this unit does not solve the problem of a missing drain hose (has to be bought separately). Water mist will slowly accumulate over time, and if you don’t place a drip pan under the draining vent, you’ll find your beautiful hard-wood floors to be soaked after using the portable AC for extended periods of time.
Your only choices are to either purchase a drain hose or babysit the drip pan.
The front-facing LED display is a little larger than the other models, but it has a sleeker look to it. This unit would probably fare well in classier settings or bright-colored rooms. Between the three units mentioned on this list, this unit has the largest black-to-white contrast ratio.

How to Choose the Best Portable Air Conditioner
So there you have it. Three portable air conditioning units which can act as a dehumidifier, fan (for air circulation), and have a sleep-mode option for gradual temperature increase over several hours.
They all come with caster wheels for smooth gliding on hard, flat surfaces, and come with a remote control for convenient temperature and mode management from across the room.
Honestly speaking, there’s nothing unique between the products besides total product weight and the interface display. They all even have the same issues of leaking water without a drain hose which is sold separately.
All in all, Costway produces great portable ACs with a competitive price tags, but there’s no differentiation between their models.
