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.

Poll: Are Kiwis allergic to “exuberance”? 🥝

The Team from Neighbourly.co.nz

In The Post’s opinion piece on the developments set to open across Aotearoa in 2026, John Coop suggests that, as a nation, we’re “allergic to exuberance.”

We want to know: Are we really allergic to showing our excitement?

Is it time to lean into a more optimistic view of the place we call home? As big projects take shape and new opportunities emerge, perhaps it’s worth asking whether a little more confidence (and enthusiasm!) could do us some good.
