Sisma annual consumable kit for all jewelry LM-D (Ready, Scope, Vision, DT Dual, Lynx) and LM 250 machines, post 2020.  Includes 2 HEPA filters, 1 deionized water filter, 1 protection glass, as well as a package of 25 lens cleaning cloths to keep your protection glass clean through the year.   If you are not sure your machine has a HEPA filter, please check the back left of the inside of the chamber.  If you see a white square with holes in it, your unit does indeed have a HEPA filter.  If you see a black square, your machine has a fiber filter - please see our 8300794 for a package of 10 fiber filters.
