Abstract
A multi-modal multi-media air filtration system which can include: a base having one or more connection features and a filter media assembly, the filter media assembly being configured to attach to the base portion at a first end. The filter media assembly can then also include a first filter media extending across a first air flow path and a second filter media extending across a second air flow path. The air filtration assembly can then also include an actuation assembly configured to selectively open or close one of the first air flow path or the second air flow path so as to alternate the degree of filtration passing through the filter media assembly based on the degree of filtration provided by the first or second filter media.
