Portable air conditioners are a great way to provide some fresh air without breaking the bank by installing a permanent air conditioning system in your office, bedroom, or any other small area. In addition to being incredibly useful, portable air conditioners also require relatively little energy, which results in bill savings. The drawback is that, despite ensuring a certain usage level, they can be rather noisy, frequently topping 60 to 70 dB.

The louder the noise becomes as you move up the decibel scale. The difference between 10 and 20 is far smaller than that between 60 and 70. A discussion can start smoothly around 60 or a bit higher, but above 70, it’s as if there’s a vacuum cleaner running or a TV on loud.

Thankfully, several extremely quiet portable air conditioners are available in the market, some of which may even reach 40 decibels. In this article, we’ll introduce you to three of the best silent portable air conditioners currently available: the De’longhi, Trotec, and Olimpia.

De’longhi

De’longhi is a leading Italian brand in the field of small household appliances, with a wide range of products that also includes portable air conditioners. The Arctic Whisper Extreme is one of the most silent models on the market, with a noise level of 62dB. Arctic Whisper Extreme may suppress noise by up to 3dB, so there won’t be a clamor over your comfort. Compared to the maximum fan speed, it offers a noise reduction of up to 50%.

The secret to its low noise output lies in the innovative silencer fitted inside the appliance. This not only muffles the noise emitted by the compressor but also significantly reduces air turbulence. As a result, you’ll hardly even notice the Arctic Whisper Extreme is on.

Trotec

Trotec is a German company specializing in air treatment for over 20 years. The Trotec Pac 4600 air conditioner is one of its most silent models, with a noise level of just 57dB.
