Filter Upgrades: With the 900 and 900c, you also have the option to upgrade to a MERV-8, carbon, or HEPA filter. The MERV-8 filter is washable, using the same methods as the prefilter. In addition, there is an option to use a carbon or HEPA filter, neither of which is not washable. Simply check these filters for build up and replace as needed.
