Case extensions for Anycubic AirPure filters which allow to fit more pieces of active coal filters.
The design comes in 1x and 2x sizes - fit’s additional 1 piece or 2 pieces.
Extensions fit the original as well as eachother so building taller ones is easy. Although it’s doubtfull the tiny fan inside the purifier can handle more than one or two extra pieces of filter.
