A filter for an air conditioner has a body formed of an air-transmissive material. The body is of a generally rectangular configuration and has a top, bottom, a front, a back and a pair of sides. The body has a plurality of cuts formed through a thickness thereof. The plurality of cuts define a plurality of cubical or rectangular members frangibly connected together. The plurality of cubical or rectangular members are separable from a remainder of the body such that the body has a size suitable for being received within a filter-receiving receptacle of the air conditioner.

A filter element for exchangeable installation into a filter housing has an annular filter medium with an annular seal secured directly or indirectly onto the first axial end. The annular seal having a positioning and sealing section and concentric annular sealing rings between which a sealing groove is formed. A radially outer side of the radially outer annular ring having a key locking system formed by a plurality of circumferentially spaced apart radial projections, spaced apart by radial indentations, adapted to positively engage cooperative configured geometries or key locking features of a filter housing when in an installed state, thereby locking a rotational orientation and position of the filter element.

A solid pet waste vacuum and bagging device is described. The device is equipped with a canister, collection chute, vacuum motor, and a bag cartridge. The device eliminates the need for an individual to come into any contact with pet waste, including the temperature and the smell conventionally known to emanate from pet waste. The device employs the vacuum motor to collect pet waste within the bag via the collection chute. The collection chute is lined with a plastic bag, which is sealed and released from the collection chute within the canister upon activation of a dispose button by the user. The device is powered by rechargeable batteries, and may be equipped with a charging cradle to maintain a fully charged battery.

This document presents an apparatus for a flexible air filter media that can be configured for shipping and storage having one or more flexible inserts mounted to the filter media along one or more portions of the accordion folds of the air filter material. The current invention permits the air filter apparatus to fold along both X and Y axes, create a tri-fold, and bend in a manner that provides for a much smaller volume for shipping purposes. The invention also permits attaching the flexible material to the center of the filter media and also inserts which allow sections of the air filter media to be nested one into another to reduce both shipping and storage volume.

An air filter assembly includes a filter element having at least one variable dimension, and a frame for engaging and supporting the filter element. The frame may include a plurality of linear segments forming a rectangular configuration, and a plurality of clips for connecting the linear segments together at corners thereof. The linear segments may be L-channel segments, C-channel segments, or may be of other form. Clips may be used for connecting the linear segments together at the corners. The filter element may have a pattern of creases or fold lines to facilitate folding thereof from an expanded configuration to a reduced configuration. A grate may be included for spanning an area bounded by the frame to support the filter element. The grate may have multiple arms and a central hub. An edge treatment may form a seal between the filter element and the frame.

A conformable, unframed, non-self-supporting pleated air filter, comprising: a conformable, unframed, non-self-supporting, pleated air filter media with an upstream face and a downstream face, wherein the conformable, unframed, non-self-supporting, pleated air filter media comprises a plurality of oppositely-facing pleats with a pleat direction and with a plurality of upstream pleat tips and upstream pleat valleys and downstream pleat tips and downstream pleat valleys, the pleated air filter media further comprising a plurality of bridging filaments on the downstream face of the pleated air filter media.

A collapsible air filter assembly for a heating and ventilation air conditioner (HVAC) system includes a filter element, and a frame supporting the filter element. The frame includes at least two edges each including a respective spring element configured to be moveable between an open state and a bent state. A compressible air filter assembly for an (HVAC) system includes a filter medium having rounded pleats configured to collapse and rebound in a controlled and repeatable manner between a compressed state and an original uncompressed state. A soft-wrapped filter assembly includes a frame in a box configuration. The frame includes rigid edges and openings to permit airflow. A filter element is encased by the frame. Flexible edge covers mounted on respective edges of the frame to provide an air seal in an HVAC system.

The present invention relates to the field of machines for cleaning, particularly vacuum cleaning devices. There is disclosed a filter cartridge for a vacuum cleaner comprising first and second opposite end walls, a side wall or walls which extend between the end walls so as to define an enclosure which surrounds a filter interior, wherein one or more of the walls comprises filter membrane material, the cartridge having an opening provided through the first end wall for receiving air-entrained detritus into the interior, the opening being defined by a rigid support structure which spans and supports the first end wall of the cartridge. The cartridge typically includes a non-return valve which closes when suction is removed so as to help prevent collected detritus escaping from the filter cartridge interior. The valve may comprise a conical valve with flexible facets, or a cantilever flap.

A foldable and disposable air filter media for insertion into an air filter frame is disclosed. The air filter media includes two or more filter pleated strips that are joined together. The outer edges of the air filter media are fixed to the frame to form the air filter. Each of the filter pleated strips have a number of pleats that increase the area to reduce pressure drop across the filter media while allowing air flow through to remove unwanted particles from the filtered air. A folding crease is formed between the opposite border edges of the air filter media allowing the air filter media to be folded for shipping or disposal.

A magnetized fastening system for applying, over an opening and surrounding fascia of a structure, a covering material including either of a flexible or rigid outer reinforced extending perimeter within which is configured a plurality of receiving apertures. A plurality of rails are adapted to being secured to the fascia in extending fashion proximate the opening, each of the rails exhibiting a three dimensional cross sectional shape with a forwardly projecting support surface within which is configured an outwardly facing narrowed slot for receiving a plurality of fasteners for securing the edges of the covering. A magnetized insert secures together the elongated channels in perimeter defined fashion over the intake opening. This can further include any of the channels being magnetically attracting, the connectors magnetically attracting metal intake surface of the air handling unit, and/or an intermediate applied strip between the rear surfaces of the channels and the intake face (typically non-metallic or non-attracting in this variant), such providing an opposite polar attraction to the magnet contained in the corner L or intermediate, linear T or cross shaped inserts, such as which can include a rare earth magnet contained in a pocket configured on an inside face of the insert.
