The read
Zehnder sits in the air stack, where the useful question is not how much the brand can sell you. It is whether the product makes the room easier to use every week.
The current Compound read is through ComfoAir Q450 and ComfoAir 70 across HRV/ERV. The filter is straightforward: fewer vague upgrades, more pieces with a clear job.
