That's why people should change the filter and have a yearly inspection, just like for cars.

But the filter is on the ingoing side and not on the outgoing side, so no moisture from the inside can aggregate there. Only the humidity from the outside but we've never had problems with that.

My HRV has filters for both inbound and outbound airflow. I do change my filters regularly, but even in the rainy Pacific NW I haven never seen any mold growth on either filter, and I have an RPi logging air quality data with a decent sensor, so I can see my PM2.5 and PM 10 are both near-zero.

Okay. I guess I have been wrong.
