Because I have personal experience with it, I highly suggest it. The purchase of other fans, particularly Turkish ones, is completely meaningless with regard to the hood. In residential settings, a non-return valve is not required for safety reasons. It is important to keep in mind that the noise coming from the kitchen is most likely dust and not the sound of a fan. The kitchen should be cleaned once a year. Every two to four years, the bathroom needs to have a thorough cleaning. The fact that these fans have been in use for such a long time is a positive. Just alive and there was almost no noise. I placed an additional order. Some cons: This one has a little lesser build quality in comparison to the ones that were purchased 10 years ago (most of which are still functioning). There are a few burrs here and there, which will eventually collect dust. When working around the clock, dust is unavoidable. One of the problems is that it is difficult to keep dust off of it, which is especially problematic for a fan used in the kitchen. You have to engage in sexual activity for an extended period of time with chopsticks that have cotton wool wound on them.
