Product review (1 stars): Horribly loud
The hood vibrates the wall and is extremely loud. The metal sheeting and chimney vibrate and make excessive noise. Additionally, the internal fan mounting system is inadequate which causes the fan assembly to rattle and make noise. The charcoal filters sound like there is gravel in the fan and some of the charcoal pieces fall out during operation. I have securely attached to the wall with additional mounting screws and used all the mounting hardware recommended in the installation manual.
