Camfil City-Flo XL filters have a MERV of 13 for green buildings
Camfil City-Flo XL is engineered to meet the high air quality standards of today’s “green” buildings. City-Flo XL has a tapered pocket design to maintain low airflow resistance and ensure full media use, plus a galvanized steel frame for improved structural integrity where airflows vary, or are unusually turbulent. It uses a fiberglass media, bonded to a broad-spectrum carbon-adsorbent material.
Ozone, diesel particulates and volatile organic chemicals, all common in urban environments, are removed by City-Flo XL, along with polycyclic aromatic hydrocarbons (PAH), substances. City-Flo XL has a minimum efficiency reporting value (MERV) of 13 when evaluated per ASHRAE Standard 52.2.
