The electronic filters inside some of our products capture particles from 0.01 µm to 100 µm with an efficiency that varies with the speed of the air passing through them. They allow the intake of purified and treated external air and, thanks to the very low pressure drops, they allow considerable savings for ventilation. The electronic filters guarantee very high filtration efficiencies up to ISO ePM1 90%. They also have a high microbicidal power due to their high efficiency on sub-microbial particles.
