F8 BOX FILTER FOR HRV SYSTEMS
These filters offer F8 level filtration and are suitable for use in all HRV systems
This F8 box filter DIY installation pack includes the “Ventsure” replacement filter, easy to follow DIY instructions and enough tape to fit the filter.
The filter is made from internationally rated F8 high efficiency filter material and manufactured in a deep pleat form to maximise air flow and make a strong hardy filter. It has a machine sealed core and a sealing lip that, once tapped will prevent air bypassing the filter.
The filter should last 24 months before needing replacement.
