Is it possible for a homeowner to clean their own blower fan? If so, is it vacuumed or wiped down with a few damp rags?

My husband is starting home PD dialysis in a few weeks. I dust our bedroom every day where he’ll be connected to the machine doing this each night. My concern is that the next day, there is a light layer of dust on the furniture I dusted the day before. Infection is a big concern with these patients. I was thinking about putting a supply vent filter on the one coming into our room, but I don’t want to damage our system. Is putting a filter on one filter going to be okay?

We are on a fixed income and can’t afford a vent system cleaning, but my husband thinks he might help the situation by vacuuming as far into the vent as he can get. Is that a waste of time?
