The F7 sock filter DIY installation is for inlets up to 230mm. Also fits Weiss ventilation systems
This filter is made from internationally rated F7 filter material. With the upgraded filtration a much larger surface area is required in order to let the air pass through the filter, it uses a cylindrical design to maximise surface area.
A smaller surface area will reduce airflow and increase fan noise, this will then cause a reduction in the life of your fan motor.
The filter should be replaced every 12 months
