A door type mosquito net is a type of mesh screen or netting specifically designed to cover and protect doorways from mosquitoes and other insects while allowing airflow. These nets are commonly used in regions where mosquitoes are prevalent to prevent them from entering homes or buildings.

Key features of door type mosquito nets typically include:

1. **Mesh Material**: They are made from fine mesh material usually made of polyester or other synthetic fibers that are tightly woven to keep out insects.

2. **Frame**: The netting is often supported by a frame made of lightweight materials like aluminum or PVC, allowing it to be easily installed and removed.

3. **Installation**: Door type mosquito nets are designed to be installed over doorways. They may have magnetic closures, zippers, or weighted bottoms to ensure they close securely after someone passes through.

4. **Ventilation**: Despite being a barrier to insects, these nets are designed to allow air to flow freely, ensuring good ventilation inside the building.

5. **Variety of Sizes**: They are available in various sizes to fit different types of doorways, including single doors, sliding doors, and French doors.

6. **Functionality**: Apart from keeping mosquitoes out, they also prevent other flying insects like flies, wasps, and moths from entering the building.

7. **Easy Maintenance**: They are generally easy to clean and maintain, often requiring simple dusting or occasional washing.

Installing a door type mosquito net can significantly reduce the intrusion of insects into living spaces, providing a more comfortable and insect-free environment indoors, especially during warm weather when mosquitoes are most active.
