EfficiencyMERV, or Minimum Efficiency Reporting Value, indicates when a filter will be least efficient. So the higher the MERV rating, the more efficient the filter. It should be noted that most fiberglass spun filters such as those found in your local grocery store are usually only a MERV 1 or MERV 2. This can affect the efficiency and air flow of your heating and cooling system, causing it to work harder to produce the same air flow and costing you more money! The Filters Fast MERV 8, 11, and 13 Filter features a low pressure drop, which means less impact on your energy use, which again will save you money!
Quality Construction and CapacityThe Filters Fast MERV 8, 11, and 13 filter is constructed of a galvanized, corrosion resistant metal support grid and 100% electrostatically charged synthetic graded density media. The media used is resistant to a wide range of chemicals and will not absorb moisture, which can support microbial growth.
The Filters Fast MERV 8, 11, and 13 filter's pleats are designed in a way to promote maximum surface area and dust holding capacity. The pleats are actually bonded to the frame to prevent any dust bypass. This means higher efficiency and air quality. These filters have 15 pleats per lineal foot which creates a greater surface area to catch airborne particles than standard filters. That also means that in most cases you don't have to change them as frequently!
