Four Seasons Filters

Four Seasons: Annual Furnace Filter is a direct replacement for standard 1” pleated filters. The Four Seasons: Annual Filter uses a patented design that uses a 4” deep pleated filter that is designed to fit in place of most 1” filters making installation a snap! The Four Seasons quickly converts your air return from using a 1” filter to a 4” deep filter, with no tools or modifications needed. The Four Seasons’ unique 4” deep design and tapered shape allows the 4” depth to extend into most air returns, taking full advantage of the unused space and to allow for more extraction of airborne contaminates. A gasket runs along the frame of the filter ensuring a sealed fit that maximizes filtration in your home or business. When upgrading your 1” filter to a 4” deep Four Seasons, you’ll require fewer filter changeouts throughout the year and save up to 10% on your energy bill.

And when upgrade your 1” filter to a 4” Four Seasons annual filter you’ll benefit from: 

  • 4X the dust holding capacity
  • 4X the media surface
  • 4X the service life*, AND
  • Up to 10% yearly savings on your energy bill

 

The Four Seasons: Annual Filter is available in a variety of MERV rating options to suit your environment’s needs, including MERV 8, MERV 11, carbon and anti-microbial. The Annual Filter works identically to a 1” pleated filter but lasts 4X as long due to the 4” deep pleats that provide additional surface area. Depending on the MERV rating, your filter will remove airborne contaminants including dust, dirt, dust mites, pollen, lint, pet dander, mold spores, smoke, bacteria, viruses, and more!

Construction:

The Four Seasons: Annual Furnace Filter uses a premium synthetic media that is thermically glued to an expanded metal backing that prevents the media from sagging during use. The pleated media is glued to the inside of a heavy-duty beverage board frame, ensuring the filter’s integrity even in high moisture environments. A neoprene gasket is adhered to the filters frame ensuring a secure fit and eliminating air bypass.
