Abstract: A nestable framed pleated air filter, including a non-self-supporting, compressible, pleated air filter media with a plurality of oppositely-facing pleats and with a plurality of upstream pleat tips and downstream pleat tips and downstream pleat valleys, the pleated air filter media further including a plurality of bridging filaments that are bonded to at least some of the upstream pleat tips. The filter includes a frame with sidewalls that are angled so that the framed pleated air filter is nestable.

Abstract: The present disclosure relates generally to air filter frames. In some embodiments, the air filter frames are nestable. Nestable air filter frames of the type described herein offer significantly reduced shipping volume, and thus shipping costs, while also providing cost-effective manufacturing. Some embodiments relate to an air filter frame including a single strip of framing material forming at least two of the four major frame segments and the frame corner between the two major frame segments. In some embodiments, a single strip of framing material forms at least three of the four major frame segments and two of the frame corners.

Abstract: A pleated filter media comprising front pleats and rear pleats, with at least some of the front pleats having junctions at which local areas of adjoining front pleat walls of the front pleat are frontally joined together. The junctions may be at discrete locations that are spaced along a pleat direction of the front pleats. For any two nearest-neighbor front pleats, the junctions of one of the front pleats may be offset, along the pleat direction, from the junctions of the other front pleat.

Abstract: Computer-implemented systems and methods for estimating a replacement status of an HVAC air filter. Outdoor weather data (e.g., outdoor temperature information), is obtained. A Total Runtime Value of the HVAC system is determined based upon the obtained outdoor weather data. Finally, a replacement status of the air filter is estimated as a function of a comparison of the Total Runtime Value with a Baseline Value. By correlating air filter replacement status with an estimated runtime of the HVAC system, a credible predictor of air filter usage is provided. By estimating fan runtime based on easily-obtained outdoor weather data, the methods are readily implemented with any existing HVAC system and do not require installation of sensors or other mechanical or electrical components to the HVAC system.
