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

What's the difference in the Comfo Air series and the newer Q series and why is Zehnder the only rocky mountain ERV/HRV for the climate zones? Why precision extraction and delivery only come from Zehnder systems and MainStreamCorporation.com

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
