Suitable for: Renovent Sky 300
G4 filter is the standard filter for Renovent Sky. The G4 filter removes 95% of dust particles, including pollen, spores, hair, sand and textile fibers, and is suitable for normal dust levels.
We recommend changing the filter at least twice a year, preferably before summer and in autumn after the pollen season has ended. In dusty and heavily polluted areas, it should be changed more often.
