Helpful information

Physical  characteristics  of  the  sound  volume  (the  sound  pressure  level)  is 

measured in decibels (dB). «Noise» is a chaotic mix of sound.

The human ear can detect sounds with sound volume of 10-15 dB and above.

When choosing a kitchen hood, it is necessary to pay special attention to technical 

indicators  such  as  the  noise  level.  This  indicator  is  very  important,  because,  and 

that’s beyond a shadow of a doubt, each of us spends a lot of time on the kitchen. It 

is especially common for women who love to please their loved ones with delicious 

cooked dishes.

According  to  the  surveys,  40%  of  women  do  not  use  kitchen  hoods  for  their 

intended purpose (it refers to the process of air suction), precisely because they are 

annoyed with the noise level.

Consequently,  such  a  necessary  and  needed  in  the  kitchen  appliance,  kitchen 

air cleaner, designed to remove airborne odors, grease, soot and smoke, becomes 

almost meaningless.

This allows you to make the cooking process the most comfortable and helpful.

For  more  complete  understanding  of  the  scale  of  decibels,  you  can  compare 

parameters of the following guidelines:
