Every package includes three charcoal and three white filters, essential for the dual filtration system. These replaceable filters are engineered to prevent the release of oil vapors and odors into your kitchen. The charcoal filters effectively eliminate odors, while the white filters block the escape of oil vapors. Replace the white oil vapor filter when the indicator square changes or the filter turns brown, typically after around twelve uses. Additionally, the package contains three paper filters for straining debris from used frying oil.
