Practical Pleat Filter - Fits in a Standard 1" Return Air Grate - M-14
These Practical Pleat Merv 14 filters do not have to be changed every 30-60 days. These filters can be left in for approximately 6 months. They are sold in a case of 2 which will give you a 1 year supply. The 5" Practical Pleat's surface area is 433% greater than a comparable 1" extended surface pleat and ultimately reduces the pressure drop of 41%. They last 4 times longer than comparable one-inch filters. Now, homeowners can enjoy the benefits of a high performance filter without the hassle and expense of retrofitting. The self-sealing gasket prevents unfiltered air from by-passing the filtering process. The Practical Pleat can capture up to 30 times more smaller partials than a standard AC or Furnace Filter. This filter reduces energy consumption, increases efficiency, decreases maintenance and extends the lifetime of the equipment.
