Reusable exoskeleton frame with U-shaped locking members and eco-friendly air filter element

A replaceable air filter element has a multilayer filter medium panel configured for mounting on a reusable exoskeleton support frame. The exoskeleton support frame is installable on a flow face of the filter medium panel and is provided with U-shaped locking members configured to detachably engage with and mount the filter medium panel. The exoskeleton support frame is configured to be reused such that only the filter medium panel is replaced, thereby reducing the environmental waste and making for a “green” eco-friendly air filter element.

Eco-friendly air filter element having fixation slits and reusable exoskeleton frame

A replaceable air filter element is provided with fixation pockets configured to record corers or edges of reusable exoskeleton support frame. The exoskeleton support frame, The reusable exoskeleton support frame is adapted to detachably engage the fixation pockets to support the filter medium. The exoskeleton support frame of the filter element is configured to be reused such that only the filter medium is replaced, thereby reducing the environmental waste and making for a “green” eco-friendly air filter element.

DEPTH FILTER

A depth filter with excellent filtration accuracy and pressure resistance performance even for fluids containing high density and high viscosity powder fine particles. A depth filter having a base material layer, a filtration layer, and a skin layer, in that order, wherein: the substrate layer and the skin layer are layers made by a nonwoven fabric being wound and thermally fused; the filtration layer is a laminate in which at least a nonwoven fabric and a net are laminated, being wound twice or more; and the nonwoven fabric contained in the filtration layer contains a mixed-fiber nonwoven fabric containing two or more types of fibers with mutually different average fiber diameters.

Filter media for filtration of cooking fumes

A kitchen appliance has a compressible filter media block for removing odor-causing contaminants from cooking fumes. The sintered-fiber media exhibits low pressure drop and high flow rate. Embedded sorbent particles are adhered to the media block, preferably via sintering, thus leaving a substantial proportion of adsorbent surface area exposed for filtration purposes. The media block can be elastic or viscoelastic making it useful in retrofit applications for use in filtration circuits not originally designed to accommodate a filter. In preferred embodiments, the media block is composed of sintered plastic fibers wherein the sorbent particles are adhered thereto via sintering.
