What HRV filter do I need
HRV has 2 size's of filters
New post 2014 plastic fan box 300mm/295mm
older pre 2014 steel fan box 305mm/295mm
It is very important to get the correct size or you may as well not put a filter in at all.
F7 or F8 is the grade of the filtration and has nothing to do with size or model. there is very little difference between F7 & F8 but there is a big pressure drop so you should avoid using an F8 in the older HRV pre 2014 as it can kill the fan motor.
F7 is fine for the new HRV I'll attach a graph to show the difference.
