OlitAir 8 Pack Replaceable Filter Media for 16x25x1 MERV 11

Please do not purchase these filter media components separately. They must be used in conjunction with our ABS plastic frame. If you are purchasing these items for the first time and do not have a framework, you will not be able to utilize them. If you are interested in acquiring our product, please search for B0BWHZFVC9. Once you have obtained a framework, then you may use the filtering medium. Please take note that the filter media provided within the linked product contains 8 pieces. Upon receipt, you will see 4 layers. Please do not misunderstand, it is 4 layers, but not 4 pieces. In order to save storage space, we will overlap the filter media in pairs. Separation of the individual pieces is simple and straightforward during use.
