Are there ongoing running costs for a heat recovery ventilation system?

We're having an MVHR system fitted in a new build extension. Beyond electricity... are there other regular costs we should factor in for maintenance and filter changes?

"Depending on how often you have your windows open at certain times of year will make the system need to work harder or less so which in turn will affect the running cost so bare that in mind."
