The level of decibels (dB) indicates the minimum and maximum noise levels. At night, you will preferably be using the minimum power setting, in order to minimize the noise.
If you plan to use your air purifier in your bedroom, you must make sure the levels of noise are low. The following air purifiers have been selected for being specially silent. They are all silent night air purifiers that will guarantee a good night sleep. They all have a minimum noise level <35dB , which means that running them in sleep mode will be quite silent.
Silent Night air purifier with Night Light
There is another point to bear in mind when buying an air purifier to use while you sleep. You should check that you buy a Silent night air Purifier with Night Light. Many air purifiers come with the option to switch off all the lights, or to dim them to be less bright at night. This is important specially if your sleep is sensitive to light. There are also some Silent Night Air Purifier with Colour Changing lights. This is not as important as being able to dim the lights at night, but can add an extra decorative and relaxing effect.
This does not apply only to Silent night air purifiers, but to any type of air purifier really. But it is specially relevant for an air purifier that you will use during your sleep, because you will be breathing that air continuously for several hours. Therefore it’s extra important that the air you breathe does not contain any harmful element. Check that you buy an Silent night air purifier ozone free. For the type of purifiers that are ozone free, you can find an article here: Ozone-free air purifiers
Running at the minimum power, the air purifier will clean the air more slowly. But at night this is not a problem, since activity at home (and traffic outdoors) tends to be minimal, which makes the air cleaner’s minimum power setting to be enough. During the day, however, higher levels of activity (people walking up and down, moving objects, etc) tend to make the dust disperse from the surfaces where it’s settled, back into the air. Also outdoors pollution, part of which gets into your home, is higher. Therefore during the day we recommend using a more powerful setting in the air purifier.
