are there any refills for our cars or do the blades have to be replaced too?

I've not seen actual refill-able blades, I just buy whole new ones from AutoZone. https://www.autozone.com/ignition-tune-up-and-routine-maintenance/wiper-blade-windshield/rain-x-silicone-advantedge-wiper-blade-windshield/288143_431278_25448

These ones have worked well for me.

Are you talking the metal arms? If so, no. Just buy new blades that fit the arms or blades that have an adapter for the arms.
