Can the hotel door replace the window?

1. Ensure air circulation: Although the door can play the role of entering and leaving the room, it can not provide natural and continuous air circulation like a window, nor can it exhaust the dirty air in the room and introduce fresh air.

2. Security risks: If doors are used instead of windows, security risks will increase. For example, in an emergency, people need to escape through windows, and the use of doors cannot meet this demand.
