This filter is a replacement for mid 2000 - Current D1 Reflections and @Home Spas, all Bay Spas & 2005 to current AFSs.
This is the single most common spa filter for Dimension One Spas. It's pretty easy to tell if this is the right filter for your spa; if it has four tabs sticking out of the top of it, this is it. It features a simple Twist-Lock attachment, so it's very easy to install in the spa.
This is the filter only, it does not include the EZ lock filter screen. The EZ Lock Filter Screen is part number 01510-501
