There is no window in the room, and the air is not very ventilated. How to ventilate?

If the room has no windows and the air is not circulating, you can try the following methods:

One: It is a relatively direct method to transform the window opening, but it should be noted that the window opening is carried out without damaging the load-bearing structure of the house.

Two: If it is a bathroom space, it can be solved with the integrated Yuba ceiling, but the disadvantage is that the exhaust function of Yuba is not particularly powerful.

Three: Install the exhaust fan. There are many types of exhaust fans, mainly ceiling-mounted, wall-mounted and window-mounted. The best effect is window fitting, and the ceiling is more suitable for the bathroom.

Four: install a fresh air system. You can install a fresh air system at home, but it will be more expensive than the fresh air system. If you have strong economic ability, you can choose.
