The Whynter 14000 BTU unit is a portable air-conditioner that uses and recycles moisture to produce cool air, and the dual hoses help cool the air faster. However, the parts that generate heat must be vented outside, and in order to keep the hoses cool enough to produce cold air, homeowners should insulate them. This unit also comes with a 3M antimicrobial air filter which filters the air by removing dust, pet hair, and dander. And, the antimicrobial agent prevents the growth of mold and mildew.

Performance and Features

Whynter ARC-143MX LCD DisplayDesigned with commercial uses in mind, the unit is meant to run in smaller spaces, or areas with low-maintenance cooling needs. It performs as expected up to 500 sq. feet. It is eco-friendly, CDC and lead free, and designed to consume less energy. One of its best features is the fact that it is portable. The unit can easily be moved from room to room without permanent set up, and you can conveniently store it in a closet or shed during winter months. The unit also features an auto drain function that draws the moisture from the air and recycles it to produce the cold air. This requires the unit to be drained, though.

There are three operational modes from this portable air-conditioner: cooling, dehumidifying, and a fan. The cooling option cools the room and dehumidifies at the same time. If you want to dehumidify without the cooling option, you would select dehumidify. The fan option simply circulates air in the room, and there are four speeds to choose from. It also comes with an easy-to-install venting kit for non-permanent venting through a window. The kit includes a window slide bar and two extendable exhaust hoses. Although it is meant to be non-permanent, the venting hoses can be custom modified to fit into wall openings or dropped ceilings.

The 3M air filter cleans the air of dust, dander, and pet hair, and the antimicrobial properties prevent mold and mildew. To keep the unit in good working order, the manufacturer recommends changing the filter every two to three months. The unit also features a simple LED display that comes with an easy-to-use remote. You can program the unit to activate or shut off at certain times with the 24-hour timer. You can change the temperature, set the timer, or change modes from the LED display or the remote. And, the unit has auto-restart and safety features. The auto-restart works well during power outages. Once the power comes back on, the unit will restart itself at the previous setting. It also comes equipped with a Leakage Current Detection and Interruption (LCDI) plug to reduce the risk of fire. The unit will shut off if the power supply cord experiences any arcing faults.

Design and Usability

As mentioned before, this is a big unit. It will take up space in a room, and it’s too heavy for most people to lift without a dolly. The product’s dimensions are 16 x 19 x 35.5 inches, and it weighs 79 pounds out of the box. Keep in mind that once the unit is plugged in and running, it will pull in moisture and need to be drained. The unit can go upwards of 100 pounds with water in it.

Designed with a two-tone exterior, the unit is platinum and black. It looks sleek and modern which allows it to blend in with most home decor, and if it is used in a server room, it blends in with the technology. Because of its bulky size though, it is best used in the corner of a room. However, window locations will largely determine where it goes.

The unit works best in small areas, but can be used in larger rooms. However, the internal temperature of the exhaust hoses can reach 130 degrees Fahrenheit, so to keep the hoses cool and prevent the unit from burning out, wrap both hoses in insulation. You will find this protects the hoses and extends their life, and it also helps cool the room much faster.

Noise Level

The manufacturer’s rating on noise level is less than 56 dBA, which is supposed to be the equivalent of a dishwasher. However, in a small room environment, the noise level is closer to 70 dBA, which is the equivalent of a lawn mower. This unit is quieter than other models, but given its design for a smaller space, it is noisier than it should be.

Energy Consumption

It is designed to be eco-friendly, so the Whynter unit consumes less energy than most other units on the market. Because it cools one specific area rather than an entire house, like a central AC unit does, it helps reduce your electric bills. The Energy Efficiency Ratio (EER) is 11.3, which is higher that other units its size. The higher the EER, the more efficient the unit.

Whynter ARC-143MX is one of the most energy efficient units on the market.


The Whynter 14000 BTU Dual Hose Portable Air Conditioner with 3M Antimicrobial Filter is a decent unit for anyone who wants to save money over a central AC unit. It cools rooms up to 500 sq. feet, and if you insulate the exhaust hoses, you can get more life out of the unit and cool rooms faster. The features for this unit are some of the best on the market, but its bulky size and weight make it awkward in small spaces. Still, it does have casters on the bottom for easy mobility.

The unit is also a little noisier than it should be, but it’s not insurmountable. One of the biggest challenges with this unit is draining it. Because it dehumidifies, it fills with water quickly and must be drained. But, there is not a draining hose to make that task easy, and the drain pan is at the bottom back of the unit. It is difficult to get to and easy to make a mess, which isn’t good news if this unit sits on carpet. All in all, if you have a small room you want to keep cool without using the central air, then this unit works great. There are a few upkeep items, but the cost savings outweigh those inconveniences.
