Both, you need something like this: https://www.philips.nl/c-p/FC8010_02/vervangingsset
I am almost certain your motor has not worn out, mine still works perfectly after 4 years of use. Please replace the filters first, which should be done yearly as is stated on the website here. Be sure to check if your specific model is compatible with the set though.
Bro my Cinnamon desktop just broke. It refused to load anymore. Could not fix it until I popped in my old AMD card, then Cinnamon magically worked again.
I suspect the drivers shat the bed but I'm not 100% sure. Went ahead and bought a new AMD card anyway and it works like a dream now.
