This depends on the location of your air purifier. Therefore it is important that you take a look at the range of decibels an air purifier lists in the product description. So an increase in fan speed = more decibels (dB) = louder device. The higher the fan speed, the louder the noise. Many air purifiers come with a control panel that allows you to change fan speed. First you need to take into consideration fan speed.
There is quite a difference between an air purifier that has 30 dB noise or 50 dB. While it might not seem such a big difference in the grand scheme of things… it is. Most air purifiers list their operating noise between 20-60 decibels (db). What is interesting is that an increase of 10 means that the sound is 10x more powerful or intense! In other words an air purifier marked as 40 dB is ten times louder than a 30 dB air purifier! Air Purifier Decibel Ratings – how much is too much? If you take a look at the graph you can see that the numbers (called levels) increases mostly by 10. To have a better idea of the scale and examples of different sounds in decibels, refer to this very informative graph below. And just as you would expect from our modern times, you can also find decent apps to measure sound strength with your smartphone! We measure sound by specialized devices called decibel meters. Sometimes we write decibel as “dB” and the higher the number, the louder the sound. Simply put, decibel is a unit which we use to measure sound. In this post, I am going to give you all the necessary information regarding this topic. In other words, how loud is the device? This might not seem such a big deal at first, but it is more important than we think. One that is often overlooked or not understood completely is air purifier decibel ratings. There are many aspects of air purifiers that are very important that you have to take into consideration before making a purchase.
