Anonymous users2024-01-23If you need two-way air exchange, you need to buy a positive and negative fan for the installation method of the toilet exhaust fan
The appearance of the ceiling exhaust fan is better, and it can be installed on the ceiling of the bathroom, and the pipe of this ventilation fan is shorter, so it is necessary to purchase a ventilation pipe that matches the pipe when installing; The wall-mounted exhaust fan is small in size and can be embedded above the wall, but due to the narrow cross-section of its exhaust outlet, the ventilation force is weak, so it is only suitable for installation in a small bathroom; The window mold leakage exhaust fan is different from the first two, it has a single and double two-way operation, which can not only exhaust the indoor air, but also supplement the outdoor fresh air to the room, therefore, the window exhaust fan has a larger scope of application and better effect.
The exhaust fan is installed in the bathroom to remove odor and drive air circulation (which can make the bathroom ventilate and the water evaporates quickly), so be sure to install it!
Around 120 can buy Longsheng, and about 140 can buy NVC.
Secret room bathroom Are you talking about closed bathrooms? If it is a closed bathroom, it must need an exhaust fan, and there will generally be a smell in the bathroom, if there is no exhaust fan, then the last time you go to the toilet, the smell is particularly heavy, and it is the same as fermentation for a long time, which is particularly uncomfortable. It would be much better to pack one.
This situation depends on the difficulty of installation, if you don't need to punch a hole will be dozens of yuan, if you need to punch the price will be higher.
OK. As long as you give find other air outlets, such as windows.
