Finding mini portable air conditioners that are compact in size is nearly impossible. In order to have an efficient air conditioner, it will need the room inside the unit to harbor all the necessary parts. Otherwise, you’ll end up with nothing more than a well equipped glorified fan. In most cases referring to air conditioners as mini is in reference to the amount of BTU, not the actual dimensions of the unit. Usually the smallest BTU for a portable air conditioner is around 5000 BTU. If a smaller BTU is what you are looking for, here are a few models that are known to be reliable and of quality also.

The Diplomat DPAC5070 is a 5000 BTU portable air conditioner is not only reliable but it is rather compact in size too. Its dimensions are 13.19” D x 17.13” W x 29” H. This particular model has many great features, can cool a room of up to 175sq ft, and has an EER of 9.2. It is also accessible at several major retailers as well as online.

Each of these portable air conditioners has its differences. However they are all great models to have for smaller rooms. With only 5000 BTU these are some of the smallest portable units round. So although the word mini may not necessarily pertain to the actual size of the unit but rather the amount of BTU it has, these models seem to have both. Considering they all have different features and functions, hopefully one of these portable air conditioners have exactly what you are looking for.
