It has been installed here for 2 weeks and everything is fine so far. I haven't noticed any external odors. The only thing you see, when it is in operation, is the toilet paper moving, which indicates that it is doing its job.

Unfortunately, it doesn't make any significant difference in both smells and humidity and vapors. I was not satisfied at all with the purchase.

After using it for a few weeks, I am quite satisfied. The only negative thing for now is that it has a little noise during operation.

We bought and installed this fan in our bathroom as we had a problem with odors coming from the other apartments. With its automatic shutters, it closes when it is not in operation, so unwanted odors are limited. We appreciate that it will also reduce the cold in winter. As for its construction, it is quite high-quality and sturdy, and its operation is quiet compared to the previous one we had.
