If your system came equipped with a metal slide-out frame, you only need to order this disposable activated CarbonWeb® cartridge. Replace this activated carbon pre-filter every 6 months depending on your use and load.  Change it more frequently if exposed to dangerous toxins, gases, or wildfire smoke.

Our CarbonWeb® "pre-filter" utilizes activated carbon technology which is most commonly used to remove gases.  This pre-filter is designed to filter gases through a bed of activated carbon which is used to combat volatile organic compounds (VOCs) released from common household products.
