  • Publication number: 20140182254
    Abstract: This disclosure proposes a new structure for pre-filter devices, and filtration systems in general, that facilitates tasks necessary to maintain performance of pre-filter banks in the filtration system. Embodiments of this structure allow the pre-filter devices to translate on corresponding structural members that make up the supporting structure of the pre-filter bank. When in position, the proposed pre-filter devices can mate with adjacent pre-filter devices to form a substantially unitary structure that prohibits fluid from flowing unfiltered to areas downstream of the filtration system.

    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.
