Buying Guide; Quietest Air Purifiers 2023

Before looking for the best product for yourself, you need to consider some important factors.

This buying guide will help you consider certain factors you must look for before choosing the quietest air purifier for yourself.

Also, by the end of this buying guide, you’ll be able to make a good decision for yourself regarding which quiet unit to buy.

Let’s start!


Consider the noise level

It is very important to consider an air purifier’s noise level before purchasing it.

The last thing anyone would want is the irritating whirring and whining noise around your bedroom or office.

So when it comes to the air purifiers with HEPA filters, the overall noise output should be between 40 to 70 dB.

Most of the quiet air purifiers I have listed above produce even less noise than 40 dB.

The 40 dB noise is quiet, like a calm background noise that will not disturb anyone.

But if the noise is above 70 dB, it will be loud enough to disturb anyone and will not be suitable for bedrooms and offices.

Also, if you want to reduce the noise level from your existing air purifier, you always have the option to run it on the lowest fan settings.

Running on the lowest fan settings will produce the minimum noise possible.


Sleep mode

Most of the quiet air purifiers do have a sleep mode in them.

But you must consider this factor seriously.

Turn on the sleep mode to ensure that your unit produces the minimum noise possible while you sleep.

The device sets itself on the lowest fan speed settings when operating in sleep mode.


Check the CADR rating

Checking the CADR rating is also an important factor to consider when buying a quiet air purifier.

The CADR rating measures the cleaner’s effectiveness in removing the pollutants like smoke, dust, and pollen from the air to improve the air quality.

The higher CADR ratings indicate faster and more efficient air purification.

For example, a q CADR rating of 200 for smoke means that the air purifier can remove smoke particles at the rate equivalent to adding 200 cubic feet of clean air per minute.

So if you have a larger room, you may choose an air purifier with a higher CADR rating to ensure efficient air purification.


Consider the energy efficiency

Considering the energy efficiency of any home appliance you want to buy is very important.

As for the air purifiers, it is also important to ensure that it operates efficiently and doesn’t consume excessive energy.

Look for air purifiers with energy-saving features like energy-efficient motors or adjustable fan speeds to help reduce power consumption and save electricity.

Along with lowering your energy bills, this will also help positively impact the environment.

So it is a win-win for both your wallet and the environment.

You must know that any standard air purifier has a power rating of between 17 and 100 watts.

Ensure the air purifier you’re interested in buying doesn’t use too much electricity.


Online reviews

Checking the online reviews of the model you’re trying to buy is also one of the most important factors.

When you check online reviews from a reliable source or customers who have already purchased the same model, this will help in making you understand how the product works in the real world.

Look for feedback on noise levels to get a better idea and understanding of how quiet the unit is.


Design and placement

Did you know that the placement of the air purifier can also affect its noise level?

Considering the models with well-designed airflow patterns that minimize noise will be good.

Also, placing the unit on a stable surface and away from walls or obstacles can help reduce vibrations and further decrease the noise level.



The size of the air purifier you’re trying to buy should be largely based on the room size or the house you are trying to clean the air from.

The size of an air purifier is also important because you should see how light and portable it is, especially if you need to carry it from one room to another again and again.



You must see the quiet air purifier’s warranty period before buying it.

A good warranty period helps you ensure that your investment is covered if any problem arises within the warranty period.


Author’s note

An air purifier should be one of the most essential parts of your home, especially if you have small children or pets.

A good air purifier helps to keep the air clean from all the bacteria and air pollutants like smoke, dust and pollen.

The most important feature an air purifier should have is quietness.

If it is not quiet, it can become a major source of discomfort for you and everyone around your home, especially while sleeping.

All the air purifiers mentioned in the above article are among the quietest ones.

See which one of these best suits you according to your needs.

So what are you waiting for?

Buy a nice quiet air purifier and start breathing in a cleaner environment.
