10 Best Quiet Air Purifiers in 2024 with Noise Comparison

Although air purifiers are known for reducing dust, bacteria, and odors in the home, some emit loud, unpleasant noises. If you have young children or a baby, a home air purifier that is too loud may disturb them. An air purifier typically emits a rustling sound of around 20 decibels (dB) when it is on a low setting. We have included the best quiet air purifier that produces minimal noise, increases productivity, and improves our health.

What is a Quiet Air Purifier?

Typically, air purifier sounds are produced by the fan and the motor. A good quiet air purifier should have a sound combined from the fan and motor, eliminating annoying sounds such as chopping through the air.

List of 10 Quiet Air Purifiers

1. Airdog X8 Home Air Purifier

Large indoor spaces are suitable for the Airdog X8. The X8 features CADR speeds of up to 470 CFM, twice as fast as the Airdog X5. Within 20 minutes, a 1000 square foot room will be thoroughly cleaned.

Noiseless mechanics don't mean greater power. A whisper-quiet fan, the Airdog X8 produces double the airflow of the Airdog X5 while operating silently in any room and is the quietest air purifier.

Air quality in a room is detected by the X8 Airdog air purifier and adjusted accordingly. The X8 can be easily controlled and adjusted when you're away from the building with its convenient app. Real-time air quality information is available on the X8's digital AQI display. Anywhere in a room can be used as a detachable air quality laser detector.

2. Airdog X3 Home Air Purifier

A reusable filter is included with the Airdog X3 small quiet air purifier, powerful TPA® technology, and a compact design. Airdog purifiers utilize TPA technology to kill 99.99% of all airborne bacteria, mold, and viruses using about 30,000 volts inside.

In addition to collecting pollutants, the Airdog ultra-quiet air purifier also destroys them. Using a washable and reusable filter saves you money in the long run. With the new X3 Airdog air purifier, you can clean the filters in a snap and let them air dry quickly.

3. Airdog X5 Home Air Purifier

With the Airdog X5 air purifier, you can easily swap out reusable plate filters. Replacing air filters can quickly rack up hundreds of dollars each year. Reusable collecting plates are convenient for the X5 Airdog air purifier, and you can wash them by hand and use them again and again. With a CADR of 220 CFM, X5 quiet air purifier for bedrooms circulates 450 square feet with its high-volume airflow. Three times per hour, it moves air throughout a 450-square-foot room.

It produces very low noise, similar to the sound of a soft hum. The X5 automatically decides what mode to use based on the air quality of the room. Apps enable remote control of the device. Don't worry if you forget to switch things off before you head home or forget to activate the unit on the way home.

4. 5300-2 Air Purifier from Winix

Winix's 5300-2 Air Purifier is one of their most popular models, featuring a True-HEPA filter that traps 99.97% of airborne pollutants, and 0.3-micron allergens can even be detected. An advanced 4-stage filtration system ensures that the air is clean and fresh. The volume of noise is between 27.8 dB and 60+ dB.

As well as adjusting the fan speed automatically, the Auto Mode function works in daylight or bright light. A total of five fan speeds are available. As a bonus, the system automatically switches to Sleep Mode in the dark to run quieter and more efficiently.

5. Airmega AP-1512HHS from Coway

Filtering the air through three stages eliminates various air pollutants. The system of this quiet air purifier reduces particles down to 0.3 microns in size by 99.97%. In addition, it can reduce the amount of volatile organic compounds by 90% or more. Via bright and colorful LED lights, you can see the air quality in real-time via a pollution sensor. Loudness range: 24.4% (low fan) to 53.8% (high fan). This type of air purifier is perfect for every home.

6. MinusA2 from RabbitAir

A smart function on this quiet air purifier detects when the room is sufficiently dark and automatically switches to Sleep Mode or other active modes when the room is sufficiently dark. This heavy-duty filter has five-speed settings, and it operates quietly, especially in lower settings, because of its Energy Certified brushless motor.

You can control the fan speed, activate or deactivate Auto Mode, and even adjust the lighting using the app compatible with this home office essentials device. A noise level ranging between 20.8 dB and 45.6 dB was recorded.

7. Pure Humidify + Cool from Dyson

The air in your home can be made safer by filtering out volatile organic compounds and particulates. The humidity should be adjusted to the appropriate level, an important component often overlooked. Most indoor air is dry, and viruses thrive in dry environments. In a humid environment, viruses deactivate much faster, reducing the risk of contracting airborne diseases.

8. HEPA InSight HPA5300B from Honeywell

In our tests, other large-room air purifiers had a maximum size of 400 square feet or less, which is on par with this Honeywell. This air purifier is also very light. Blueair's HealthProtect 7410i and Dyson's Pure Hot+Cool were more difficult to handle thanks to their handles, however. Unlike many bigger models, this powerful cleaner can be easily moved from room to room when needed. It comes with an automated set-it-and-forget-it mode.

9. Blueair Pure 411

You remove the washable fabric pre filter sock from the air filter by unscrewing the fan component. One tap on the top controls low power, medium power, high power, and off. The appliance cycles the air in a room of 161 square feet five times an hour. The unit's quietness and small footprint make it ideal for small bedrooms.

10. Wynd Plus

Wynd Plus is a small quiet air purifier that is about the size of a water bottle. There's no HEPA filter in the device, but it can remove all particles greater than 0.3 microns, including wood smoke and auto emissions. Besides the indoor air quality sensor, it comes with a microfiber travel bag and a kickstand that props it upright.
