The bottom line: these are well-made pleated filters that deliver measurable dust reduction and odor control for systems that accept an actual depth of 4 3\/8 in. Installers will appreciate the sturdy beverage board frame and metal mesh support, while allergy sufferers who need filtration roughly equivalent to MPR 1500-1900 will find improved air quality.
