Design and Structure

The designers have put a lot of time and effort into this machine. Simply looking at its design in comparison to others, it shows pretty well.  The Soleus Air LX-140 is a portable air conditioner with a unique design of its kind and built in a way that it can be easily placed or positioned in a room.

Despite its size, the coolant can be installed in most part of the room. This small-sized portable air conditioner is well complimented by a power of 14,000 BTUs and can easily cool an area of up to 525 square feet. For window installation, the Soleus Air LX-140 supports a window kit to give it a perfect fit.  It vents the humid air out of the room through an integrated hose. The venting is also possible with open ceilings and attics. It is very easy to handle unless you need to shift the air conditioner to another window, which would require you to reinstall the window kit as well. This may look like a lot of work, but is surely worth it.

The Soleus Air LX-140 is designed in a way that it absorbs and evaporates humid air through its own cabinet. This means that you are not troubling the elements in your attic or ceiling by pushing humidity in there.

Its air conditioner filters are completely washable and if you give them some extra care, it will keep up in delivering its beauty out. You can reach the filters from the back portion of the coolant.

On the grounds of energy efficiency, it is rated at 10.1, which is actually very good especially in cases of portable air conditioners. It definitely is very eco-friendly and doesn’t give out a lot of CFC to do any harm to nature.

Pros of the air conditioner

  • A bit smaller in size, making it easier to install.
  • Dehumidifier keeps the room fresh and cool.
  • The active remote control allows you to control it from anywhere in the room.
  • It is 24-hours programmable.

Cons of the air conditioner

  • Exerts negative airflow in the room.
  • Noisy, better not to install very close to bed.

liked Features I liked

I bought this air conditioner for one of our rooms that is about 350 square feet and I must say it really works according to my expectations. I have tried many other air conditioners but I still prefer to have this coolant for that particular bedroom. I would suggest this coolant to those who are good to pay a considerable small amount in exchange for a smart portable air conditioner.

  • The first thing that attracted my attention towards this machine was its size. It is one of the smallest portable air conditioners at its level.
  • It is fairly easy to install and you can do it by yourself too. There is no hard mechanics involved and is light enough to handle.
  • Because of its size and elegant design, it gives your room a classy look. Having it in white colour make it looks fantastic to a room.
  • It takes less than 25 minutes for the coolant to cool the room temperature as per your comfort.
  • The coolant saves electricity, putting a cap on your electricity bills. It saves your wallet some money.
  • The feature of controlling the fan speed is something that I liked the most. You can easily shift the gears of its fan from your bed.
  • You can easily wash the filters from the back side of the air conditioner.
  • The coolant supports wide louvers, which you can adjust for directing the flow of air when running it on fan mode.
  • I would say at such a small price, you can’t get anything better than this.

liked Features I didn’t liked
However there are not much things that you won’t like about this amazingly small air conditioner.

  • The Soleus Air LX-140 seems a bit noisy at times compared to other portable air conditioners. When running on its fan mode, you may feel like you are being bombarded.
  • Deep sleepers can install this coolant in their bedroom; otherwise it’s better to keep it in the living room.
  • It has a 46 dBA noise level, which is low and good, but may sometimes not quite good when having a hard time to sleep.
  • Because of its single hose design, the air conditioner fill the room with negative airflow. If you pay some extra attention, you might also hear the hissing sound from the gaps in doors and windows.
  • The Soleus Air LX-140 has a 9.5 gallon bucket. In warm and humid conditions the bucket can get full quick even in small amount of time and you will have to take care of it.


The Soleus Air LX-140 is a perfect air conditioner for those who give more stress on better cooling features. The coolant is very energy efficient and keeps the electricity bills down. The size of the coolant makes it easy to install.

The air conditioner may have a bit of the noisy side, but you can install it in the living room, or far from your bed. I like how it cools down the room temperature in no time.

Moreover, the one year warranty is good enough to assure the sturdiness of the machine. On a price like it, this portable cooling machine is one of the best you can get.
