Replacement Filter for Perfect Fit™ SPECIFICATION DATA Efficiency: (Efficiency Ratings Based on ASHRAE Standard 52.21999.) Minimum Efficiency Reporting Value (MERV): 10 at 492 fpm. Initial Efficiency: 22% (0.3-1.0 micron particles). Initial Efficiency: 87% (3.0-10.0 micron particles). Initial Pressure Drop: 0.17 in. wc at 492 fpm Temperature Rating: -40° to 140°F (-40° to 60°C). Approvals: Underwriters Laboratories, Inc.: Listed to UL900, Class 2. APPLICATION The replacement filter is a high-efficiency, long-life filter for Perfect Fit media air cleaners. It captures a significant amount of the airborne particles in the air that circulate through the filter. Replacement Schedule: Replace every 12 months or more often if filter appears dirty enough to block airflow through heating/cooling system. Dimensions: See Fig. 1 and Table 1. B FEATURES • Higher efficiency than OEM filter. • Captures particles as small as 0.3 micron. • Pleated filter for greater media capacity. A • Low pressure drop reduces strain on equipment, provides a comfortable air flow, and helps maintain equipment efficiency. • Easy installation. Angled edge fits neatly into offset side of air cleaner frame. SPECIFICATIONS IMPORTANT The specifications in this publication do not include normal manufacturing tolerances; therefore, this unit may not exactly match the listed specifications. Also, this product is tested and calibrated under closely controlled conditions, and some minor differences in performance can be expected if those conditions are changed.
