Buying Guide For The Best Quietest Portable Air Conditioner
Portable air conditioners have emerged as the best alternative to other portable cooling devices. It allows the user to enjoy cool environments on demand. With minimal audio output, these quiet units are suitable for noise-sensitive applications. A list of the best quietest portable air conditioners has already been discussed. This buying guide will help the user understand the importance of a few governing parameters.
1. Noise Level
The noise level is the topmost priority for the quietest portable air conditioners. These portable units have components like the compressor, which creates louder noise. Due to the portable design, the compressor is fitted inside the main body, unlike the split ACs installed outdoors. These portable units are thereby modified to keep the noise level low. Several units operate at a noise level below 60 dB, equivalent to the sound of human conversation. Soundproof materials are also used to lower the noise output further.
2. BTU
The overall selling point of a portable conditioner is its cooling power. This power is measured in the British Thermal Unit (BTU) to make the user aware. The BTU rating depends on various parameters like room temperature, size, etc. The portable air conditioners are designed for a BTU rating of 5,000 to 15,000, enough for mid-sized rooms. When the atmospheric temperature is high, and more cooling power is needed, some units offer cooling power beyond 15,000 BTU.
3. Room Size

To ensure efficient and faster cooling of the room, the coverage capacity must be more than the size of the room. The portable air conditioners are suitable for rooms sized between 250 to 500 sq. ft. Users can determine the coverage capacity with a BTU rating and room size chart.

Efficient energy consumption allows better running of the AC units without increasing the energy bills. These portable air conditioners are rated with several certifications to ensure efficient power consumption. The AC units are rated with Seasonal Energy Efficiency Rating (SEER) to make the user aware of the power consumption. The quietest portable air conditioners usually have a SEER rating of 2 to 10. Some brands also offer energy star certification on their products rated between 1 to 5 stars.
5. Type Of Control
To access the basic functions of a portable air conditioner, various types of controls are offered. The most common control type is the buttons or knobs on the air conditioner’s body. Users have to touch these controls to adjust cooling and other features physically. To add comfort to the users, remote controllers are also offered.
