Are air purifiers really as silent as they say they are?
Noise pollution adversely affects the lives of millions of people. Multiple studies have shown the direct links between noise and health. According to studies, around 50,000 people just in the European Union die prematurely each year from hart attacks caused by traffic noise. The study also showed that people living in streets with average noise levels above 65-70dB(A), the average risk of heart disease is 20% higher than for people living in quieter streets.
Other problems that have been proven to relate to noise include stress related illnesses, high blood pressure, speech interference, hearing loss, sleep disruption, and lost productivity.
Most air purifiers on the market use HEPA filters, and these air purifiers have a noise ranging from around 35dB at the lowest fan speed to over 70dB at their most efficient fan speed. In other words, to use a HEPA air purifier at its most efficient fan speed, which is recommended for any type of air purifier, exposes people to a noise level similar to street traffic.
At LifeAir, we don’t believe in replacing one hazardous pollutant, i.e. air pollution, with another hazardous pollutant: Noise. That is why are our purifiers are silent. Our IonFlow air purifiers are virtually completely silent, with a noise level of only 21dB and work 24/7 at maximum efficiency. WHO and EPA recommend 35-40dB as the maximum sound level when sleeping without putting your health at risk.
Below is a chart shows the sound levels in different environments.
