It's very effective in blocking dusts and insects.
Recently purchased the allergy screen for some of our windows. They definitely filter out the smaller dust particles compared to normal window screens. With the recent fires near us, the rooms without these new screens had ash in the room but rooms with the new screens were clean. Definitely will get more windows set up with these screens. However, will note that there is considerably less free air flow with these window screens, understandably so. So take that into consideration if you have a window where you rely on breezes to flow.
