REPLACEMENT PACK OF 18MM COTTON FILTERS. FITS ALL NOVA MICRODERMABRASION MACHINES.
Each pack contains around 50 pieces of large (18mm) cotton filters that goes inside the machine generally under the air intake connection and fits all NOVA Microdermabrasion machines.
What is the difference between the 18mm cotton filters and the 11mm cotton filters?
Both 18mm cotton filters and 11mm cotton filters are needed for the NOVA Diamond Dermabrasion machines. The smaller (11mm) filter acting as a first catch for the dead skin cells being vacuumed by the machine. The larger (18mm) cotton filter is being a secondary catch to keep out any debris that may have bypassed the first initial filter.
