Quality, Strong Square Mosquito Net -White

The Square Mosquito Net Has;
Fine mesh prevents mosquitoes (and even smaller biting insects, like midges from entering. To do this well, mesh holes need to be small (e.g. mesh count ≥ ~ 156 holes/in² or holes small enough so insects can’t pass through). 
Good ventilation
Even with fine mesh, good designs allow airflow so the net doesn’t become too hot or stuffy. This is critical especially in warm, humid climates. 
Lightweight and portable
Especially for nets used over beds or for travel, lighter nets are easier to hang, fold, wash, and store. Some nets collapse or fold like umbrellas, or have stands. 
Durability
Strong seams, strong mesh fabric, resistant to tearing and ripping. Material should be washable without losing effectiveness. 
Easy installation / use
Includes simple hanging (hooks, ceiling points), or freestanding frames/stands. Some window/door meshes use magnetic tape or strips for sealing. 
Aesthetic / neat appearance
Fine mesh nets that look tidy, colour options, clean finish, and good shape (square, dome, rectangular etc.) make them more pleasant to have in the house, encouraging regular use. 

Hygiene & maintenance
Washable, removable, easy to clean; nets that can be detached or folded up when not in use; low-maintenance design helps longevity. 

Cost-effectiveness
Over time, a durable fine mesh net is a good investment: instead of relying on insect sprays or other repellents, one net can last many years if well cared for. Also fewer health costs if you avoid mosquito-borne infections. (Globally acknowledged in WHO / malaria prevention resources.)
