Loud air purifiers: the hidden dangers you don’t know about
What To Know
- If possible, adjust the fan speed to a lower setting when noise is a concern.
- Placing the air purifier on a soft surface, such as a carpet or rug, can absorb vibrations and reduce noise.
- If possible, isolate the air purifier in a separate room or area to minimize the impact of noise on living spaces.
Air purifiers have become an indispensable part of modern homes, offering relief from allergies, asthma, and other respiratory issues. However, one common concern among potential buyers is the noise level of these devices. In this comprehensive guide, we will delve into the factors that influence air purifier noise and provide actionable tips to minimize it.
Factors Affecting Air Purifier Noise
1. Fan Speed
The fan is the primary source of noise in air purifiers. Higher fan speeds generate more airflow, which can result in increased noise levels.
2. Filter Type
Different filter types can contribute to noise levels. HEPA filters, known for their high efficiency, tend to be noisier than electrostatic filters.
3. Airflow Design
The design of the air purifier’s airflow channels can impact noise. Some models feature optimized airflow paths that minimize turbulence and reduce noise.
4. Size and Shape
Larger air purifiers generally have more space for noise-dampening components, making them quieter than smaller models. The shape of the air purifier can also affect airflow and noise levels.
Measuring Air Purifier Noise
Air purifier noise is measured in decibels (dB). The lower the dB rating, the quieter the device. Here’s a general guide:
- < 50 dB: Very quiet, suitable for bedrooms and offices
- 50-60 dB: Moderate noise level, acceptable for most living areas
- > 60 dB: Noisy, may be disruptive in quiet environments
How to Minimize Air Purifier Noise
1. Choose a Quiet Model
Look for air purifiers with a low dB rating. Read reviews and consult user feedback to assess the noise level before purchasing.
2. Adjust Fan Speed
If possible, adjust the fan speed to a lower setting when noise is a concern. This may reduce the air purifier‘s effectiveness slightly, but it can make a significant difference in noise levels.
3. Place on a Soft Surface
Placing the air purifier on a soft surface, such as a carpet or rug, can absorb vibrations and reduce noise.
4. Use a Noise-Dampening Cover
Some manufacturers offer noise-dampening covers that can be placed over the air purifier to further reduce noise.
5. Isolate the Air Purifier
If possible, isolate the air purifier in a separate room or area to minimize the impact of noise on living spaces.
When Noise Matters Most
1. Bedrooms and Studies
In bedrooms and studies, where quiet is essential, choose air purifiers with a dB rating below 50.
2. Open-Plan Living Areas
For open-plan living areas, a moderate noise level (50-60 dB) is generally acceptable. Consider air purifiers with optimized airflow designs to minimize noise.
3. Shared Spaces
In shared spaces, such as offices or classrooms, noise can be a distraction. Opt for air purifiers with a dB rating below 55 to ensure minimal disruption.
The Quietest Air Purifiers
Based on reviews and user feedback, here are some of the quietest air purifiers on the market:
- Dyson Pure Cool Air Purifier
- Levoit LV-H132 Air Purifier
- Winix 5500-2 Air Purifier
- Coway Airmega 400 Smart Air Purifier

The Takeaway
While air purifiers can generate noise, there are numerous ways to minimize it. By choosing a quiet model, adjusting fan speed, and using noise-dampening techniques, you can enjoy the benefits of clean air without excessive noise pollution. Remember, the quietest air purifier for your needs depends on the specific environment and noise sensitivity.
