Is it redundant to open a window when we have an air-to-air heat exchange system? (kbin.social)

I've moved into a place with one of these systems and it seems to have a lot of benefits. But I prefer to open a window every day and get fresh air in. Doesn't that cancel out the advantages of the heat exchange system?

The system is filtered, so the air feels lovely to breathe. There’s car traffic nearby so I imagine it’s better air quality via the system.

But at times it feels like there’s not enough of it, so opening the window in my room for an hour helps that.

The fans are running at 50% as recommended by the installer. The house usually has no more than one person during the day, so that seems logical. But I wonder now if it would be worth turning them up to 75% instead of opening the windows.
