This is why you should always check the noise level on the purifier you buy. The quietest air purifiers have a noise level of about 15 – 25 dB while the noisiest range between 65 – 75 dB.

If you want these features, you may have to pay a little extra, but it is worth it. The auto mode enables the filter to adjust the speed of the fan according to the level of pollution in the room. This speed will only be increased to high or medium if the pollution level is high, according to the sensor’s reading. These sensors minimize energy usage and the noise level by ensuring that the air is always adequately clean, so the fan speed does not go to high.
Night mode: Of course, if you want a silent air purifier, you want one that can be in the room while you sleep. This feature ensures that the purifier’s lights are dim enough to allow you to sleep comfortably. Dim lights ensure that you have a restful night without having to deal with any disturbances.
Coverage: You need to know what amount of space the filter can clean at a time. Of course, the bigger the fan, the more room it can cover.
