It is true that we all want to live in the cleanest, purest, and healthiest environment, and our homes and workplaces should be no exception. These quietest room air purifiers help to eradicate smell, smoke, pet dander, and dust while leaving behind clean air to exhale.

That being said, usually, the air purifiers typically make noise and can be considered loud, annoying, and disrupting. Newer, quieter air purifiers intend to be effective without creating the sound. When dealing with the pollutants and loud traffic noise when traveling to and from work is terrible enough, but it is worse when similar elements attack your home and workplace when it should serve as a place of safety where you can enjoy a personal, peaceful, and serene place.

The quietest air purifiers solve these issues by operating noiselessly as it enhances your air quality and rids your home and workplace from toxic contaminants. The majority of the air purifiers only run quietly in low settings, but the quietest air purifiers can perform the same at their maximum level. Noise level is the most evident priority when searching for the quiet model. Next comes the coverage area for sufficient and enough protection.

One of the other significant areas of concern is the number and type of filters as they indicate the level of protection to expect and the specific type of pollutants that can be removed from the air. Other key aspects that need to be assessed when buying the best air purifier are dimensions for storage and mobility, fan speeds for flexibility in output, and CADR rating for efficiency performance.

What are Air Purifiers?

Air purifiers are used to remove pollutants and contaminants from the air. They can be manufactured as small, stand-alone purifiers or large purifiers that can be attached to the HVAC. Air purifiers eradicate dust, dander, smoke, mold spores, volatile organic compounds, and pollen from the air using high heat, UV light, exhaust systems, ionic technology, or HEPA filters.

Do Air Purifiers Make Noise?

Noise is most likely the most significant aspect to consider while searching for the quietest air purifier. It is also more often the inspiration that makes you search for quieter air purifiers mostly among the plug-in air purifiers. Fans generate noise in air purifiers. That is why reducing the speed of the fan gives a quieter sound.

The best way to check the noise of these air purifiers is to consider the decibels on the purifier and compare the number to common sounds followed by the evaluation with related decibels to get an idea of its sound production. It is important to mention that the noise level of the quiet air purifier a person tends to buy is rated in decibels (dB). The instrument having the lowest decibels (dB) tends to be “noiseless” than the others are.

It is recommended to choose a quiet air purifier which comprises of the smallest figure. The foremost aim of the device that has a noise level should be between 15-25 decibels (dB). This range is said to have a similar sound made while whispering.

Is It Good to Sleep With an Air Purifier?

Generally, there is no problem with sleeping with an air purifier. Following stated are some of the advantages of an air purifier during sleep:

  • It clarifies the air from allergens: People who are the sufferers of food fever and those with respiratory problems would benefit more from the clear air purifier.
  • Most of them have low noise levels: The little level of noise can let you sleep properly while the purifier does its job effectively.
  • Some can even double as a lantern for kids: This means that if your child is afraid of the dark, they won’t have to worry and fuss around because of the nightlight feature, amongst which some of them can be dimmed off too.

The point to consider in mind is that some air purifiers also have timers and other settings so one can set it to low noise and low speed, especially when the person wants to sleep peacefully and calmly or have it run at high speed when the pollution is worst.

Types of Air Purifier

There are 7 most commonly used types of Air Purifiers:

Ultraviolet Air Purifiers

With the help of ultraviolet light, these Ultraviolet (UV) air purifiers help in getting rid of potentially dangerous viruses, germs, bacteria, and pathogens from the workplace or home. The idea of these Ultraviolet (UV) air purifiers generated from hospitals that use special ultraviolet light bulbs to sterilize patient’s rooms and labs. On the other hand, Residential UV air purifiers are small, solid filters that purify the air at home through a chamber filled with UV light. The UV light kills these harmful germs and viruses by breaking molecular bonds in their DNA.

HEPA Air Purifiers

HEPA air purifiers use a sophisticated air filter to get rid of 99.7% of all particles which are greater than 0.2 microns. This means that HEPA filters are highly effective at eradicating particles like pollen, dander, mold, and dust from the air.

Activated Carbon Air Purifiers

Activated carbon air purifiers are useful in removing smoke, smell, fumes, and gasses from the house. People who are sensitive or allergic to smell like smoke or any gas should consider Activated carbon air purifiers. Usually activated carbon air purifiers comprise HEPA filters that help in eliminating particles from the air as well.

Ionic Air Purifiers

Ionic Air purifiers are entirely quiet and work without a motor. They release negative ions into the air, which connects with positively charged, flying particles like dust, making these particles heavy that they finally fall out of the air. There are some ionic air cleaners that have electrostatic precipitators that trap positively charged particles to a metal plate inside the air purifier.

Electronic Air Purifiers

An Electronic air purifier is one solution that works with the furnace or A/C to charge and captures airborne particles with the help of static electricity. These purifiers can remove 99.98% of the contaminants from the air using HEPA filters and positively charged ions. They help in purifying the home with these built-in HEPA filters in conjunction with heating at cooling systems. In the center, an electronic air cleaner makes sure that the air passes through the HVAC system that can trap the smallest particles. Further, if any impurity is left then it is cleaned and removed by positively charged ions generated by the electronic air ionizer.

Central Air Purifiers

The central Air purifier cleans the air of the entire house by linking it to the central heating and cooling system. These purifiers work quietly in the ductwork of the home to remove 99% of most and pollen, 98% of the dust, and 94% of the germs in your home. Also, these purifiers heavily reduce the influence of allergies, asthma, and viruses on your health. They help to increase the heater life and A/C by filtering out the small dust particles that might affect the appliances.

Air-to-Air Exchangers

These Air-to-Air Exchangers originally freshen the home by eradicating old, musty air and replacing it with healthy, fresh air. These exchangers can also help to control the temperature and humidity of the environment with the help of using “energy recovery ventilators”. Air-to-air exchangers can also help you regulate the temperature and humidity of your home using “energy recovery ventilators.”
