RHEEM/RUUD/PROTECH

The Rheem-Ruud ProTech PD540040 MERV 8 17 1/2" x 21" x 5" Media Filter includes deep pleats that securely trap contaminants. Designed with a MERV 8 rating, it captures large and small particles of dust, dirt, mold, pollen, dander and odor. Made from moisture-resistant materials, the filter will not allow bacteria, mildew or mold to grow. Sturdy support fingers give the filter rigidity. Replace the filter once every six months for healthy and clean indoor air.
