They introduced them a year or two ago. They only offer limited popular sizes, and only in 1" thickness (as of this date).
The filter is a dry one (not oil-impregnated like their automotive filters). They require a cleaning fluid, and it's not the same as the cleaning fluid used for the automotive filters.
