• Frame is produced using post-consumer recycled materials
• The unique monobond p" frame concept involves a 1-piece frame sealed to the media under heat and pressure
• The synthetic media consists of polyester fibers bonded together in an interlocking pattern of tiny lint and dust traps and this configuration maximizes dust loading while minimizing resistance to air flow and surface loading
• Improved aerodynamics reduce restriction to air flow
• Safe, easy, fast installation
• Larger effective filtering surface area
• Classified class 2 by UL
• Filters perform best in conditions where large quantities of lint and dust are present
• The rugged construction makes these filters industry leaders in the high velocity system, prefilter market
• Made in USA

  How often do I need to change my air filter?
  
• There are many factors that can determine when an air filter should be changed. How often the HVAC unit runs, air quality, humidity and other factors can vary greatly from application to application. For most 1, 2 and 4 deep panel or pleated style filters, it is usually recommended to change the filter every 2-3 months. In many commercial and industrial applications static pressure can be monitored and the filters can be changed when they reach their recommended final resistance in inches of water gauge.
  
• What is MERV?
  
• MERV stands for: Minimum Efficiency Reporting Value. MERV is part of the ASHRAE 52.2 Test Standard that determines the ability of an air filter to remove particles of a specific size from an air stream. Air filters can have a MERV of 1 to 16; the higher the MERV, the more efficient the filter is at capturing particles
