My builder has asked me which of two cfm levels I wish to go with on the HRV. Either 60cfm or 90cfm. The key is that the 90 will be a lot louder than the 60 and I really am striving for quiet.

Given the limited scope that we are pulling air from, am I wrong to go for the quieter 60 cfm?

Any thoughts or suggestions would be great.

I will watch this as well, as I'm aboutto buy a unit as well, but wonder the same,

maybe you want to ad the sqft of the house, # of bathroom's and how many will live in it,

i have bin googling it as well, but struggle a bit with defining how much air flow as well,

I dont know, as I have not checked it, but would you be able to turn a 90 unit back to 60, and if you find you need more flow, you bring it uo a bit ?
