Something that has worked well for me is to rinse my nose with just plain saline in a can from the drug store. Nothing fancy . When I come in from a store of our I just give a few sprays . Seems to keep everything mild. I occasionally use zicam which is holistic plant based. Wash my hands and eat right. I sat next to my coworker on a business trip he caught the flu and had fever and coughed on me for 2 days and I didn’t get it.
