WINGMAN1 Replacement Pad Overview The use of technology made it possible for the Wingman1 to be the overall most efficient 1” filter available. Our 1” electronic air filter offers superior air flow while capturing harmful indoor air particles. These specially formulated glass fiber replaceable pads are manufactured from recycled crushed glass known as “cullet." The continuous glass fiber media becomes polarized by the charge from the power supply and acts like a powerful magnet to attract sub-micron particles. Each order of replacement pads consists of 2 pieces of fiberglass, cut specifically to your filters size. Each change requires 2 pieces of fiberglass and is recommended to be changed at least every 3 months. The initial purchase of the Wingman1 will come with a 3-month supply of replacement pads.
