  • Publication number: 20140137738
    Abstract: A non-woven textile based filter media is produced from polyester fiber generated using recycled polyethylene terephthalate (PET) beverage bottles, and that non-woven textile based filter media is used to make an air filter. By controlling the diameters and lengths of the PET derived polyester fibers, a non-woven textile based filter media that exhibits a natural Minimum Efficiency Reporting Value (MERV) of about 8 (without requiring electrostatic treatment) and a pressure drop of 2.9 PSI or less can be achieved. A related exemplary embodiment is an air filter fabricated entirely from recycled materials, including a recycled cardboard frame, the non-woven textile based filter media made from recycled PET derived polyester fibers, and a support structure made of recycled plastic or metal wire.

  • Patent number: 8715383
    Abstract: A filter clip for holding a filter media over a supply/return/exhaust of an HVAC system includes a hook portion that secures to a grid of a suspended ceiling system and a filter holding portion that is connected to the hook portion such that the filter holding portion is biased towards the grid and/or a grille. An air filter placed between the filter holding portion and the grid and/or grille is held against the grid and/or grill until, for example, until construction is complete or the filter needs to be changed or removed, thereby covering the supply/return and reducing contamination of the HVAC system from construction dirt/debris.

  • Patent number: 8696783
    Abstract: A method of forming a filter unit comprised of a filter element and an encircling peripheral encasement frame to which the filter element is sealed. The frame is moulded in situ by solidification of a liquid, solidifiable moulding composition (e.g. a curable resin or a matter thermoplastic resin that solidifies on cooling) provided around the periphery of the filter element. The method may comprise the steps of: (i) providing a filter element having front and rear faces and a bounding peripheral edge, (ii) locating around the peripheral edge of the element a mould unit which seals against peripheral regions of the front and rear faces and which together with the peripheral edge defines a mould cavity, (iii) filling the mould cavity with a solidifiable, liquid moulding composition, (iv) effecting conversion of the liquid to a solid, and (v) removing the mould thereby producing the filter element.
