Getting the perfect air conditioner for your home boils down to get at least two things right: your living space area in square feet, and a general idea of where (which room) you’re going to be using it. The coverage area is important to know because this is what informs the cooling power that your unit is likely to have, and an idea of where you place it will help you decide which type of AC unit you should buy. If you’re looking for something that you can move around, then a portable air conditioner like the Whynter ARC-143MX might be worth looking into. It’s not the best dual hose portable air conditioner, but it still has a lot to offer. Make sure you get to the end of this review to find out more about it. Make sure to also check out how it compares to the most popular air conditioners.

Why We Like It – Whynter ARC-143MX Dual Hose 3-in-1 Portable Air Conditioner

The Whynter ARC-143MX Dual Hose 3-in-1 portable air conditioner is a modern, well-built AC unit that is a great alternative to a window air conditioner since you’ll be able to move it around easily. It’s got state-of-the-art features, dual hose operation, and 3 functions rolled into it. The dual hose operation, as well as its cooling capacity, are features that make it very similar to this compact Whynter Portable Air conditioner.

  • 3M Antimicrobial filter
  • Auto drain function
  • 3 operational modes
  • No Wi-Fi support for app control


With a cooling capacity of 14000 BTU, the ARC-143MX Whynter Portable Air conditioner is very much capable of servicing an area that’s no larger than 500 sq ft, and in this respect, it is pretty similar to the Whynter ARC-14S 14,000 BTU Dual Hose Portable Air Conditioner. In fact, you probably don’t want to even look at a 12000 BTU air conditioner.

Aside from air conditioning, the dual hose AC unit also features a dehumidifying function, and has a fan that can be adjusted between three different speeds. If you’re unsure about how dual hose air conditioners work, check out our info articles.

Energy Efficiency

A lot of people tend to worry a lot about the amount of electricity that air conditioners tend to require to run. While this might be a well-founded truth, there is one thing that you could do to make sure that it doesn’t cause a spike in your electricity bill, and this would be to use its 24-hour timer. And, this will prevent you from needing to use proper AC disposal. Unlike the LG LP0817WSR, it, unfortunately, doesn’t have a sleep mode, so you’ll just have to use the timer to set it up in terms of how exactly you need it to work. Additionally, if you want something more customized, then you’ll want to build a DIY portable air conditioner. Or, you can try using a fan and ice to make an AC in mere minutes.


The Whynter 14000 BTU dual hose portable air conditioner stands out from the Whynter ARC-12SD in that it’s got a special air filter – the 3M antimicrobial filter, to be specific. This is in addition to the washable pre-filter that they both have, and is very important for keeping the air that you breathe clean. It doesn’t come with a carbon filter, but this is something that you can decide to add on yourself should you see fit. It does function differently than swamp coolers, which is why it’s helpful to learn the inner workings of an air cooler.


Like most portable air conditioners in the same price range, the Whynter portable AC is backed by a 1-year warranty on both warranty and parts, as well as a 3-year warranty on its compressor. This means that should you experience any problems with your unit right after purchase, you will be able to get free technical assistance or even replacement as long as you reach out to the customer service team in good time. If you’re still shopping around for portable units with good warranties, consider giving our NewAir portable air conditioner review a read too.


There’s a lot of value in getting an air conditioning unit that’s got dual hose operation like the Whynter ARC-143MX. For starters, its cooling efficiency is better than that of a single hose unit, so your room will fill up with cold air a lot faster than it would with a single hose AC. As is standard with modern air conditioners, the ARC-143MX will also include a remote control for convenient functioning, and will also come with a window kit for easy installation.
