Energy-efficient portable air conditioner with dual hose system, auto drain technology, and superior dehumidifying

If you want an air conditioner that’s also a great dehumidifier, look to the Whynter ARC-14S. It not only is very eco-friendly, but it has auto drain technology and dual hoses that help make the unit so good at pulling moisture from the air and also cooling it down. Built to work in larger rooms, you can use the Whynter in living rooms, bedrooms, and anywhere else the air is hot, sticky, dirty, or all three.

14,000 BTU cools 500-square feet

The Whynter ARC-14S is pretty powerful with 14,000 BTU. That’s enough power to cool down a 500-square foot room to comfortable chill. You can choose from three modes with this unit: an air conditioner, fan, or dehumidifier.

Auto drain

The auto drain technology plays a big part in making this unit energy-efficient. The tech pulls moisture out of the air and turns it around to create your cool air. Using moisture this way helps keep the water out of the tank, so the air conditioner is able to work longer without having to be emptied.

Dual hose system

Many air conditioners just use one hose. The ARC-14S uses two. Warm air from both the inside and outside is pulled into the unit, cooled, and then sent back out through the exhaust hose. While one-hose systems do it all through one hose, this unit uses two. This makes the portable air conditioner more efficient and effective.



In addition to the energy-efficient features mentioned earlier, the Whynter ARC-14S is CFC-free and uses R-410A refrigerant, which is eco-friendly. It’s also made from lead-free parts, so you can rest assured that this unit is running as efficiently as possible without hurting the environment.

Very effective dehumidifier

One of the ARC-14S’s greatest strengths is just how efficient the dehumidifier mode is. If you run it all day, it can pull 100 pints of water from the air. That’s way more than other air conditioners, and is especially convenient in very humid climates where just cold air isn’t enough to make it feel comfortable.

Has two filters

The Whynter is also very good at cleaning the air. It has a pre-filter and a carbon filter. Together, these filters help remove odors and allergens from the air, so your air is fresher and cleaner. To take care of your filters, just rinse off the pre-filter and replace the carbon filter every 2-3 months.



The Whynter is pretty loud. It’s not great for smaller areas where all the noise is contained, and it isn’t great when you’re trying to sleep either. Keep the unit in larger rooms where it was intended to be used, and the sound won’t be as bad. For sleeping, be sure to keep the unit in its quietest mode.


There are other units that cost less and have more power. Depending on your needs, you might not really care about humidity, so having that really effective dehumidifier isn’t worth the cost. However, you do get the dual hose system and two filters with this unit as well, so consider those three unique features before you decide against the ARC-14S.

Overall Review

The Whynter ARC-14S Dual Hose portable air conditioner is an eco-friendly, effective air conditioner with some unique features, like a dual hose-system, two filters, and a really effective dehumidifier. If you have larger rooms and live in a hot, humid climate where dust, pollen, or pet dander are really troubling, this is a great unit to help deal with all three issues.
