The invention relates to filters, including air filters, and more particularly to a low cost mounting and retention system.
An air filter traditionally includes three components, namely: (1) a filter element; (2) a housing base; and (3) a housing cover mounted to the base and enclosing and/or sealing and/or retaining the filter element in the housing. The parent invention of the noted '144 application eliminates the need for the third component, and makes the use of a cover optional. In the preferred embodiment, the noted parent invention eliminates the need for the third component by directly attaching/retaining and sealing the first component to the second component, independently of the third component (the cover). The parent invention is particularly useful as an intake air cleaner for internal combustion engines.
The present invention arose during continuing development efforts related to the noted parent invention, and provides a further mounting and retention system.
