I use a similar nasal spray for allergies (Becodefence). Basically a physical barrier coating the nasal passages. For me and my allergies, it's super effective.
Never thought about using it to block viral infections, but it makes sense: coating the nasal passages with artificial "mucus-like substance" so particles don't reach the membranes. Makes total sense that approach also work for viruses.
