Abstract
An ultrasonic filtration device may be incorporated into or otherwise installed in an extractor hood in a cooking environment. The ultrasonic filtration device aids in the elimination and/or reduction of contaminants in the air produced as a byproduct of cooking. Particulate contaminants are bombarded with high-energy pressure waves, thereby breaking up the particulates and reducing their size until they are no longer noticeable and/or hazardous to the user.
