Whynter ARC-143MX Air Conditioner

Retailing for about $522.83, this unit is not exactly cheap. However, for the amount of power put out from this device, we at Air Conditioners Rated believe this price to be a solid bargain for what you’re actually getting. The Wynter ARC-143MX performs as both an exceptional air conditioner, and dehumidifier. In addition, it will also perform some air purifying tasks to help you breathe easy. While it may not be the most attractive of the units we have reviewed, it is certainly one of the most powerful and effective.


Cooling Performance

With an immensely impressive 14,000 BTUs of cooling power, the Whynter ARC-143MX can adequately service estimated areas of up to 500 square feet. Additionally, with a maximum airflow of 226 cubic feet per minute, this unit is capable of removing up to 91 pints of moisture from the air each day.


Efficiency / Certifications

When it comes to efficient performance, this unit boasts an Energy Efficiency Ratio of 11.2, which stands proudly above the industry average of 9.7. Efficient operation is furthered with the addition of 3 fan speeds, allowing the user to operate their device on the minimum necessary speed. Unfortunately, information regarding whether or not this product is energy star certified was unavailable to us at the time of this review.

This product is also UL-listed, meaning that it has been assessed by the industry renowned experts at Underwriters Laboratories, and the results have concluded that this unit is safe for public use.



With a wireless remote control included with this product, the user is enabled to issue commands to their unit from anywhere in the room. Further, there is a built-in 24-hour programmable timer on this unit, which enables the user to programme when in the day they would prefer their unit to function. This is useful for those of us who spend a lot of time out of the house, and would like to return home to a cooled environment.

Another reliably convenient feature is the Auto Restart function. This will enable your device to reboot itself following a power outage, continuing on the setting it was previously functioning on. This is especially useful for those of us who live in environments that suffer frequent electricity blackouts.

Auto drain fully exhausts all condensate automatically in most environments.



With a gross weight of 100lbs, and a net weight of 79lbs, this unit is incredibly heavy for a portable unit. We strongly advise seeking help when transporting or installing this product in your home.

Operating at a noise level of <56dB, the Whynter ARC-143MX is incredibly quiet for its considerable output figures. For reference, the average human conversation would usually register somewhere around 60dB.

While the weight of this unit may sound intimidating, four caster wheels fastened to the bottom of this product make for easy transportation from room to room.

The user interface consists of a digital display on the upper part of the front-face of the device. We found this panel to be easily understandable and certainly commend Whynter for its design.

Unlike other portable air conditioners, this unit includes a 3M™ anti-microbial high air flow (HAF) air filter. This essentially removes particles such as dust, dander, with an antimicrobial agent preventing the growth of mold and mildew. Additionally, the Whynter ARC-143MX also has an additional washable pre-filter which removes larger particles from the air, such as hair or dirt.

Aesthetically speaking, the Whynter ARC-143MX is unfortunately slightly lacking, looking quite dated with its two-tone rectangular shape with jutting straight lines.

Help & Support

Whynter customer service representatives are contactable via phone or email. Additionally, they may also be contacted through an online message page on their website, or through one of their various social media presences.

If you do not wish to speak to a representative, Whynter also maintains an extensive troubleshooter, and FAQs section on their website.

This product in particular is backed by a one year appliance / three year compressor warranty. This compressor warranty is less than some of the other brands we have reviewed, such as Frigidaire, who provide a five year warranty on their compressors.

For more information regarding warranty policy, we recommend you contact Whynter at your earliest convenience.



In conclusion, the Whynter ARC-143MX is one hell of a portable AC. Providing a relatively huge amount of cooling power when compared to other portable ACs, this product is an effective air conditioner, dehumidifier, and even purifier in some senses. Granted, as with all units, there are issues. For one, the weight and size of this unit are not exactly ideal, and the slightly dated design looks a bit old fashioned from an aesthetics standpoint. There are also a number of functions missing such as Sleep Mode, and Energy Saver Mode. However, this unit more than makes up for these problems, with its immense amount of cooling power.

Note: While the Whynter ARC-143MX may provide some air cleaning services, this unit is by no means a substitute for a specialised air purifier unit.
