Purolator Key Pleat Ultra Pleated Filter, 15 Inch L x 20 Inch W x 1 Inch T, 300 fpm, MERV 8, 0.21 Inch WG, 100% Synthetic Fiber Media

The PerfectPleat ULTRA filter is designed to consistently increase efficiency throughout the service life of the filter. The PerfectPleat ULTRA filter has approximately 25% more media than our standard capacity filter, and also incorporates an antimicrobial. The antimicrobial is applied to the media to preserve the integrity of the media throughout the filter’s useful life by inhibiting microbial growth. PerfectPleat ULTRA filters have an initial MERV 8 rating respectively, but the efficiency increases significantly when dust holding begins. PerfectPleat ULTRA filters have distinctive self-supporting characteristics that allow a pleating pattern, which promotes airflow and maximizes dust holding capacity (DHC). The PerfectPleat ULTRA filter is ideal for applications where pleated filters are currently in use, and higher efficiencies are desired or required. It is also suited to high moisture conditions where bacterial growth may be likely to occur on air filters.
