Knowing your room size is by far the most crucial aspect for taking into consideration. Under no circumstances you should buy a device which is not powerful enough to include the entire room. If you are trying to save money by the reducing the size of your purifier then this is saving at the wrong place. Because, if the air purifier is not strong enough to cover the whole room, then the positive side of the device will not be in effect.
Before you decide on any air purifier, must keep in mind the square meters of your room where it has to be used and then check the maximum capacity of air purifier as stated by the manufacturer. You can find this important piece of information either on the packaging or may be in the product description inside its box.
Air cleaner noise level for is another critical factor, which should be taken in consideration to decide. A noise which might not be disturbing at the start can get quite agitating after a few hours. While some devices are creating almost no noise, others can produce more disturbing noises. Considering the noise level is important if air cleaner has to be used in your bedroom.
Always check which decibel value the manufacturer provides for the device. This information is listed in dB / decibel value. You will find it in the product information. Also, this list, will help you to estimate how loud the air purifier should be during the air exchange.
0 to 10 decibels: almost inaudible
11 to 20 decibels: very quiet, comparable to a calm PC fan
21 to 30 decibels: quiet but audible
31 to 40 decibels: as distinct as a fan – from 35 dB can be annoying in the bedroom
41 to 50 decibels: audible, comparable to birdsong or a radio
More than 51 decibels: loud and disturbing, not recommended
