Master/DownEast Spas: MICRO FILTER w/ Microban (x268325) OEM

This is the outer filter used in ALL Master Spas and Down East Spas that are equipped with the black stem-pipe and lid. Treated with Microban, an anti-microbial treatment that helps control bacteria growth and gives it that blueish appearance. This filter is to be used with the smaller Eco-Pur Mineral Cartridge inside.

Master Spas has discontinued the 3-Stage Filter System that had an additional filter BETWEEN the outer filter and Eco-Pur, called the "Depth Loading Filter". This system was sold in 2008. This will now be the only filter you need with the Eco-Pur inside it.
