Zehnder CA series vs. Q series vs. Other ERV or HRV

[@TheZambie1]

Good video thanks

[@BOAH247]

So this is a ERV and HRV unit ?

[@PassiveHouseCody]

Zehnders can be both with a change of a core and a switch of an option. ERVs do a little more and cost a little more.

How loud is the Q series? Thanks

[@PassiveHouseCody]

Both CA and Q units are the most quiet on the market due to the motors and EPP custom molded housing. Thanks
