Top 6 Quiet Air Purifiers in 2022

be quite

There are several kinds of air purifiers in the market depending on its requirement, technology, and many other functionalities. However, most of the air purifiers in the stores are generally selected for domestic usage.

The suitability for household and bedroom requirements is more significant in that case than anything. On that list, one familiar complainant we heard was the “annoying noise factor” of the air purifiers in previous days. Thanks to modern technology, most air purifiers in the latest market have the least amount of noise.

Nevertheless, for your guidance, let us find what are the Quiet Air Purifiers in this year. Here is Know Your Facts recommendation for the Top 6 Quiet Air Purifiers in 2022. Read and enjoy.

Human Hearing Range

Hearing directly depends on the frequency of the source of sound generation, which is measured by Hz (hertz) or in decibel (dB)(as loudness). For a young, healthy average personal hearing range is identified as about 20 to 20,000 Hz. From decibel, this range varies between 0 – 180 dB.

Typically any loudness pass the 85dB level identifies as damaging to our hearing.

Actually, no one can cover the entire region of this hearing range. There are indeed no audible frequencies from person to person. Also, there might be some loss in hearing frequencies with age.

According to this sketch, any equipment with a frequency below the 40 dB limit is okay to work with at night in front of good sleep.

And it is hard to bear any frequency higher than 85 dB, even at night.

Most household electrical equipment does not have much higher vibration by design, but most old air purifiers have an annoying noise impact on our sleep by default.

The Reason Behind the “No Quiet Air Purifiers” Label

There are several reasons for the noise factor behind the air purifiers. A few of them can be identified as follows.

1. Frequency of the number of waves emitted in a certain period by the purifier.

Emitted frequency directly depends on the structure of the equipment and interior design. Most of the air purifiers in the market are specially designed to absorb their frequencies by their exterior design.

Other than that, purifiers’ height, space it covers, and design material directly impacts their vibration frequency.

2. Filters lifetime and amount of impurities clogged inside.

Air purification means filtering air contaminants through a filter setup by automated enforcement. The main reason behind the noise generation is the filtration process and the clog of the impurities in this process.

It might be observed that when the purifier is operating without a filter, there is a minor noise level than when it is running with filter ON. Also, a rise in noise might be seen when there is a significantly higher level of impurities collected in the filter.

3. Noise depends on the amount of energy consumed or the size of the air purifier machine

Most air purifiers with higher power consumption have a high filtration capacity, generating relatively higher noise.

The practical situation is that these larger air purifiers are unsuitable for the bedroom and a calm, quiet place. They are used by restaurants, office areas, and higher machinery operational surroundings.

4. Environment Parameters can change the Noise transmission through the atmosphere

Even though we do not get most of our attention on this, you might observe that sound can hear clearly after a good rain. Likewise, several factors can impact sound wave travel. Mostly like atmospheric temperature and humidity.

Usually, sound travel through a medium, even though we cannot see air particles in the atmosphere. Parameters like humidity and temperature control these particles’ vibrations and behaviour in our surroundings.

Other than these, there are some factors that involve your air purifier’s noise. Most of them cannot be controlled by the user. So, at the selection point, making the right move leads to the proper start of controlled noise of an air purifier.
