Short answer
In a nursery, an insect screen’s job is not only to stop mosquitoes. Dust and pollen can also bother a baby’s airways. That is why a nursery needs a filter that holds back fine particles too.
What to look for
- Does it stop tiny insects? Tiny insects such as sand flies can pass through ordinary mesh.
- Does it hold back dust and pollen? The nanofiber layer is what makes this difference.
- Does it contain chemicals? Choose a mechanical filter instead of insecticide-treated mesh.
- Is it easy to clean? A hook-and-loop filter can be taken off and rinsed.
- Is fitting safe? Models that need no drill or screws also suit rented homes.
Made to measure: hook-and-loop or roll
