Abstract
Provided are filtration systems, filters, and corresponding methods of installing and using a clean room filter. A filtration system may include a housing defining a vent opening and a filter opening. The housing may include a knife edge disposed about a perimeter of the filter opening and configured to extend downwardly. The filtration system may include a filter removably attached to the housing. The filter may include a frame having an opening and a channel disposed about a perimeter of the opening. The filter may further include a filter substrate disposed in the opening of the frame, a gasket disposed about a perimeter of the opening within the channel, and an adhesive compound disposed within the channel between the gasket and the channel. The filter may be configured to engage the knife edge of the housing, such that air may be configured to pass between the clean room and a duct via the filter.
