What is the most silent air purifier?

Imagine sleeping in a room with an air purifier working at its high settings. While resting in a quiet environment, you start noticing a noise. What’s that noise? Oh, it’s my air purifier. Well, now you might ask how to get rid of it? Luckily, we have the silent air purifier available in the market.

Just to make things clear: the quietest device produces the noise around 25-40 decibels. However, you can usually get purifiers with the noise level of 50-60 decibels. Stay away from those air purifiers with 70-80 decibels levels – they are the noisiest.
