Our Z-Line Series MR-13 Environmentally Friendly pleated filters features the latest in media technology to achieve MERV 13 while maintaining low pressure drop and good service life. The filter is optimized for LEED compliance in new and existing buildings as well as providing a cost-effective upgrade from the lower efficiency pleated filters for a variety of commercial and industrial applications.

The MERV 13 filtration media incorporates 100% synthetic fibers which are electro-statically charged, thermally bonded and are manufactured in an engineered gradient structure. The thermally-bonded fibers do not absorb moisture and will not support microbial growth. The engineered grading structure media supports high dust holding capacity and long filter service life.

The MERV 13 filter is the perfect upgrade from regular pleated filters, poly ring panels or standard disposable panel filters.

The filter fibers are thermally bonded and manufactured in an engineered gradient structure. An expanded metal reinforcement are laminated to the air-exit side of the media by a thermo-setting adhesive to maintain continuity of the radial pleats. The expanded metal is galvanized to resist rust and corrosion. The media is pleated in a tapered radial configuration. The pleated cartridge is bonded to the peripheral interior of the outer frame. A heavy-duty moisture-resistant beverage board is utilized for an encasing frame. The frame is internally laminated to the pleated cartridge apexes.

Z-Line MR-13 Series filters are rated Class 2 under U.L. std. 900. Z-Line MR-13 filters are rated to withstand temperatures up to 180 degrees Fahrenheit. Z-Line MR-13 Series filters are rated MERV 13 when tested in accordance with the ANSI/ASHRAE 52.2 Test Standard.
