There is a fine dust that seems to be coming from the heat pump that gets on everything. The heat pump has been looked at and cleaned, and no one can find any problems. Any ideas? Thanks.

Basic fiberglass air filters do very little to trap dust and fine particles. It may be wise to consider investing in a high-efficiency electronic air cleaner. They can trap even virus-sized particles, and can certainly handle dust.
