How Air Purifier Fans Operate

Before you can suss out just how loud a particular air purifier is, it can be helpful to know how they work. Most air purifiers use a series of fans. One set of these fans draw air in, while the other set pushes air out. Fans do make noise, so that is something to consider.

How Loud is an Air Purifier?

Modern air purifiers tend to be on the quieter side, often being considered ambient noise. Though the actual noise output of an air purifier will vary depending on the model, each unit should advertise a decibel level. It is important to note how decibel levels work. These numbers operate via a logarithmic scale that goes up in powers of ten. So, if an air purifier is marketed as having a noise output of 70dB, that will make it ten times louder than one with 60dB.
