How Quiet is Quiet When it Comes to These Models?
All machines having a fan or a motor are bound to make a sound, but it does not have to be loud. Air purifiers tend to let out whizzing or whirring sounds that often irritate the user. If you want an air purifier for your office or your bedroom, the most essential factor after its functionality is its sound.
There are several quiet air purifiers in the market. In fact, some are so quiet that you will not even notice their presence. These quiet purifiers not only offer comfort, but they also reduce noise pollution. Some of the quietest air purifiers have sound ranging from 35 dB to 70 dB.
Some ion flow air purifiers in the market are almost silent in their function. These have the sound range of only 21 dB and manage to function 24/7. You have to choose an air purifier that manages to offer optimum functionality and also manages to offer the least amount of noise pollution.
How Do Quiet Air Purifiers Work?
Quiet air purifiers work by reducing the noise produced by fans during air filtration. Some of them use more efficient fans that do not make much noise during the filtration process.
In most cases, different models use silent turbine designs that increase the air inlet area, consequently reducing the noise produced by the purifier. Noteworthy though, different manufacturers use technology that they find most suitable for noise reduction depending on their unique selling points.
When Would a Quiet Air Purifier Come in Handy?
A quiet air purifier comes in handy for the purposes or situations discussed below.
Noise Reduction
Quiet air purifiers are essential if you want a device that will clean the air in your room or area 24 hours a day but with minimal noise distraction, especially while sleeping. Therefore, you might need to consider the noise level of your bedroom air purifier. This is indicated in decibels (dB). Go for one with the least count to make sure that the unit can perform optimally but at very minimal noise.
Neutralizing Unpleasant Odors
If your space continually accumulates unpleasant smells from pet odor or an air pollutant, then an air purifier is essential. Such chemicals can present detrimental health risks if you get exposed to them for long durations, and pet odor is often accompanied by dander and allergen sources like pet hair. Therefore, having a quiet air purifier will improve the indoor air quality of your space and save you from such discomforts.
Improved Sleep
Noise can cause sleep distraction. Most air purifiers perform optimally at high fan speed settings but are usually very noisy. There is so much discomfort that comes with having a bedroom air purifier that makes noise for you as you sleep.
At the same time, it is essential to keep it on all through the night. Therefore, the quietest air purifiers can help purify the air in a room at high fan speed settings while minimizing noise. The quality of your sleep will be improved because of both the clean air and reduced ambient sound.
Aspects to Consider Before Buying
Here are some things to keep in mind as you shop:
Types of Filters
There are three main types of filters that you can choose from when purchasing air purifiers, which include true HEPA, ionic, and activated carbon filters. All these clean the air using different mechanisms. Depending on the kind of air contamination that is present in your space, you can choose an air purifier that has the most appropriate filter for your air quality needs. An activated carbon air filter is best suited for the absorption of odors, while a HEPA filter is best for removing pet dander, mold spores, or any other airborne allergen.
Room Size
Air purifiers have been designed to have optimal performance in spaces with specific dimensions. The dimensions are usually expressed in cubic or square footage. Manufacturers indicate the specific room coverage that is appropriate for a particular model. You should compare this room coverage with the size of your space before buying one.
Washability or Replaceability
Air purifiers come with either washable or replaceable filters. Washable filters will last you a long time, but you will be required to remove them regularly for cleaning. Replaceable filters do not require regular cleaning. You are supposed to take them out and install a new one about every six months when they wear out.

People Also Ask
The following section features some of the common questions that people ask about quiet air purifiers. These questions will give you deeper insight into different aspects of these air purifiers to help you make an informed decision when purchasing a unit.
46dB is relatively soft according to the ratings by the American Academy of Audiology. The noise level can be compared to that of a refrigerator humming, bird calls, a library, a dishwasher, or low-volume streamflow. It is the lowest limit of the urban ambient sound.
CADR stands for Clean Air Delivery Rate, which is expressed as cubic feet per minute. The unit measures the cubic feet of air contaminants that an air purifier could remove per minute within a specific room coverage. The primary purpose of a CADR rating is to show you how effective and fast your air purifier could clean air within a specific duration and room size.
The higher the air purifier scores in its CADR rating within a specific contaminant category, say pollen, smoke, or dust, the more efficient it is in removing them within a given room size. The highest possible CADR rating for pollen and smoke is 450 and 400 for dust. Therefore, the closer the CADR rating is to these numbers, the more effective the device is.
It is highly recommended that you leave the air purifier running all the time, both day and night. Air purification is a continuous process given that the air quality in your space keeps changing every minute. Hence, for maximum performance and best results, keep your air purifier on for 24 hours.
