Rexair Rainbow E-2 HEPA Filter / Exhaust Hose Interface (R10520) Universal A clogged HEPA cartridge restrictsThis genuine Rexair part (Part #R10520) is the HEPA filter and exhaust hose interface assembly for the Rainbow E 2 cleaning system. It seats at the exhaust of the machine, where the HEPA media captures the fine dust and allergen particles remaining after the water bath separation, while the interface provides the connection point for the exhaust hose. Together they ensure clean air is returned to the room and the hose attaches with a proper seal.
