I didn’t see any holes in the exhaust fan at home, so I felt it was useless. I never turned it on after taking a shower. The exhaust fan switch is together with the bathroom heater. There was no hole in the toilet.

1. I didn’t even see the exhaust fan hole in my house. The exhaust fan switch is together with the bathroom heater.

2. This is an integrated design, and the hole is small, so it is difficult to see without careful observation.

3. You think there is wind blowing out, which is a wrong analysis, because it is dehumidification, which discharges wind from the inside to the outside.
