Replacement high performance filter for the CT 36 AutoClean.
Filters 99.9% of particles down to 1 micron in size, allowing you to reach full capacity without clogging or caking. Features easy tool free installation, this main filter is optimised for self cleaning, eliminating the majority of dust created at the source before it is ever released into your environment. The cloth based auto clean filter features a special 'M' fold to prevent build up. Tough fabric is more wear resistant when the scrubber handle is used. Every other fold is shorter, easily allowing dust to shake out when the handle is pulled.
