Does your unit look like this?
This is the RO system that requires the filters below. It takes one of each (one Item# WC201, one Item# WC202, and one Item# WC203). It also requires the AC36 membrane (Item # W207). However, the membrane needs to be replaced only every 3-4 years. The filters should be replaced once a year. These filters and membranes fit both the AC15 and the AC30 models.
