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
