Why homeowners ask for it
No-see-um mesh has smaller openings than standard pool screen. It can be useful in areas where tiny insects are a bigger nuisance.
Tradeoffs to consider
Finer mesh can reduce airflow and may collect more debris. It can also cost more than standard mesh, especially for a full pool cage rescreen.
Best use cases
Some homeowners choose it for specific sides of a patio or enclosure instead of every panel. Ask what makes sense for the property and budget.
