    The Airguard® DP® Pleat - standard size 1-in. filter is an extended-surface, synthetic, pleated filter that provides low pressure drop and high dust holding. The DP Pleat is designed with a consistent pleat shape on predetermined centers, causing dirt to collect evenly over the entire surface of the media. This technology results in a slow, steady rise in resistance for maximum dust-holding capacity. 
    Minimum Efficiency Reporting Value (MERV) 8 and MERV-A 8-A efficiency rating
    Low initial resistance for energy savings; DP = 0.14-in. water gauge
    Extremely high dust loading
    Exceeds American Society of Heating, Refrigerating, and Air-Conditioning Engineers Standard 52.2 air cleaning specifications for filters installed upstream of cooling coils
    100-percent thermally bonded, synthetic, proprietary media to resist moisture, delaminating, excessive buckling, collapsing, warping, and bending
    Mechanical efficiency – achieves MERV 8 rating before and after a conditioning step
    Die-cut pattern providing 50 percent more contact points between media pack and frame
    Integral die-cut cross members for strength and rigidity
    Galvanized steel metal grid to resist rust, maintain pleat shape, and prevent fluttering
    1-in. depth
    14 pleats per foot
    Any application or air handling system
    Built-up filter banks, central station air handlers, rooftop units, and side access housings
    Final filters for MERV 8 requirements
