The CRC's Ozzy Mat – 4 multi-layer filter, is designed to introduce microbes called Ozzy’s into the SmartWasher System. It must be placed on the mat support white side up. The OzzyMat helps reduce excess clogging during its 30 day or 1 month use. It must be changed monthly to help keep the microbe colony healthy and keep your SmartWasher working at peak performance. These microbes migrate from the OzzyMat into the Ozzy Juice located in your SmartWasher tank and break down organic waste. Recommended for normal to heavy parts cleaning applications.
