WebNov 4, 2024 · In a humid climate, the air conditioner will dehumidify better . That’s only a benefit as long as the air flow isn’t so low that it turns the condensate to ice. To summarize, a high-MERV filter can: Add resistance to the air flow. Increase the pressure in the duct system. Increase the energy use of the system. WebApr 15, 2024 · Filters are pleated to provide enhanced performance characteristics for certain applications. Through pleating, filters can offer increased surface area and density without impacting airflow. Thus, pleats enable filters to collect more particles without increasing pressure drop or energy consumption.
WebMar 7, 2008 · The results showed that the performance of pleated filters depend not only on the size of the particle but also on the pleat count of the pleated filter. Based on filter quality factor, the optimal pleat count (OPC) is always higher than that based on pressure drop by about 0.3–0.5 pleats cm −1. Web1. A filter comprising a filter medium with a pleated structure comprising a nanoweb layer and a scrim, wherein the nanoweb layer comprises fibers with a number average diameter less than 1 micron and layer thickness less than 50 microns, wherein the ratio of total medium thickness-to-pleat-spacing is less than 0.15, wherein the nanoweb layer has a …
