  • Publication number: 20080099401
    Abstract: A filter includes filter media and a housing surrounding the media. The housing has an outlet and is sealed such that all fluid flow out of the outlet must first enter the cartridge and pass through the media. The housing has multiple inlet flow paths configured so that fluid impinging on the housing is diffused as it enters the cartridge and is prevented from flowing directly towards the filter media.
