Sound is measured by decibels or dB. A quiet portable air conditioner would be around 40-45dB. 40 dB is about the same noise level as raindrops or humming. Not too bad. However, portable air conditioners range anywhere from 40-65dB. 60dB is about as loud as a group of people conversing, so the difference between 40dB and 65dB can be quite noticeable. Listed below are 2 brands that are known to have the quietest portable air conditioners.
Soleus
Soleus is a distinguished brand of portable air conditioner. They are designed for your home, office, cabin, or patio. At only 45dB, its quietest unit sounds rather similar to that of a constant humming. Their air conditioner units also have many other great features and functions such as 4 in 1 technology, remote and LCD screen operation, dual hoses, 3 fan speeds, an energy efficient dual motor design, and a 24 hour timer. 2 of their quietest models are the LX-140BL DB and the PE2-09-32. Both are very much like in their features; however, the PE2-09-32 has an evaporative system and 9000 BTU and the LX-140BL DB has 14000 BTU. Soleus portable air conditioners are also known for their efficiency and easy to use units.
Sharp CV-P10RC
Sharp is another well-known brand and at 38dB, it has some of the quietest portable air conditioners around. They say their portable units feature a “Library Quiet” design and have 3 different units with noise levels of only 38dB. These models are the CV-P10RC, CV-2P10SC, and the CV-2P10SX. The CV-P10RC has 10000 BTU while the other 2 have 10500 BTU. All 3 models also have what Sharp calls Plasmacluster Ion Technology which helps take the stale smell out of the room as well as eliminates static electricity. Sharp’s portable air conditioners are also Energy Star compliant, reducing the energy being consumed. They will also absorb over 60 pints of moisture in the room per day.
Unfortunately there aren’t too many options when seeking the quietest portable air conditioners. Many brand’s portable units tend to range from 50-65dB. The 2 brands listed above have topped other brands by at least 5dB which is a rather large difference in noise level. Not only are they the quietest brands but they are reputable. You are guaranteed to get a quality product when purchasing a portable air conditioner from them, especially when the amount of noise your unit may make is an issue. You will not find a quieter air conditioner anywhere else. When deciding between the 2 brands above since you now know they both have the quietest portable units, make sure to take other factors into account. Look at their other features and functions such as, their mobility, weight, size, fan speeds, BTU, the ease of operation, whether it comes with a window kit, and what EER it has. You are sure to find a great and quiet product when choosing a Sharp or Soleus portable air conditioner.
