Looking for a good wall exhaust fan is pretty tough nowadays. There are vintage wall mount fans available, and there are more recently launched fans with modern features. If the vintage look floats your boat, but you still need a somewhat recent performance level, the Broan 509 is the best exhaust fan for kitchen use that you can purchase.\r\n\r\nWhy We Like It - Broan 509\r\nWith the Broan 509, Broan-NuTone made a comeback to the mid-end of the market all the way back in 2007. And even now, 13 years later, this exhaust fan still holds up as one of the best fans to buy for indoor ventilation. Performance and build quality are still immaculate, according to today\u2019s standards.\r\n\r\nPerformance\/Power\r\nThe Broan 509 performs extremely well, just like the lower-priced variant Broan-Nutone 512M. With 180CFM airflow, it can cover up to a 170 sq. ft. room. The fan is plastic made, but it is designed well and can move a lot of air through.\r\nDurability\/Build\r\nThis wall exhaust fan is very rigidly built. So the body, the plastic grille, and the housing, in turn, don\u2019t have a lot of give to them. This can make the installation process a nightmare, but we are going to get to that. Primarily, with heat expansion, the wall mount can break off. The iLiving 10-Inch Shutter Exhaust Fan doesn\u2019t have the same problem, even though it\u2019s similarly built.\r\nNoise\/Sound Level\r\nThe Broan 509 comes with a pretty good Sone rating and is very quiet. Even though the fan doesn\u2019t come with any speed control wall switch, you can purchase a separate Broan utility if you need variable speed. At lower speed levels, this exhaust fan is basically inaudible. At just 44 decibels, it\u2019s excellent for running while you sleep.\r\nVersatility\/Modern Features\r\nThe grille length and the duct size aren\u2019t very ideal, to begin with. And as said before, the housing isn\u2019t that adjustable. That might be problematic for some during the installation process. And it doesn\u2019t have any form of backdraft protection, unfortunately. So insects, cold air during winter, etc., can enter very easily. Overall, this fan isn\u2019t that great in terms of versatility. Go for the Hon Guan 6 Inches Exhaust Fan for adequate backdraft protection.\r\nValue\r\nAt just above $60, this fan offers a lot of good stuff. But there are places where the fan does lack too. So it entirely depends on you, whether or not you think if the tradeoffs are worth it. But one thing\u2019s for sure; the Broan technical support customer service team is excellent at following up with the one year limited warranty.\r\nBroan 509 Wrap Up\r\nThere are a lot of wall exhaust fans out on Amazon and other marketplaces, good and bad. The Broan 509 is one of the good ones, even counting all the missing features.
