Importance of Filters and how easy it is to order new ones!
All you have to do is:
Click the “Order Filters Now!” button below.
Either select your filter from the drop down menu or enter your product quick code # from your filter sheet, that was provided by your tech upon your last Shafer service call. (You can also search by type and size.)
We advise you change your 1” HVAC system filters monthly and year round or when your system is in use. For 2”-4” filters you can follow this general rule- you should get 1 month of use for every inch of filter width. Thus, a 4” wide filter should give you 4 months of protection.
Sizing Furnace Filters and Air Conditioner Filters
If you are replacing a frame type furnace filter with a pleated filter or electrostatic filter you need to know the dimensions of the filter frame in order to select the proper size pleated or replacement air filter. Length, Width and Thickness are the measurements that you need to know.
Standard Filter Size Measurements
Usually these dimensions are not exact. For example a 20x20x1 filter will actually measure 19.5×19.5x¾. When you order the ordering dimensions will be 20x20x1. This difference between standard size measurements and actual size measurements allows for variations in filter rack sizes and also ensures that the filter will fit into a standard size filter rack.
