Review on 🕷️ Ultra Breeze Bug Screen Kit - White for Fan-Tastic Vent U1550WH by Kenneth Rich

You really don't need this umbrella, the holes in the umbrella are pretty big. My husband said he would just use a piece of cut out screen taped to the vent if I don't order it's not worth sending back. The actual vent cover has a louvered opening on the back which could potentially let wasps etc into the cover. While this should protect against wasps, it does not work on small flying insects or the nasopharynx.
