A Bacteria Filter offers an additional layer of protection by trapping ultra fine particles delivering the utmost level of air filtration. Replace monthly or as dirt shows on the filter. When using a standard hose, it goes at the air outlet between the machine and long hose. When using a heated tube, the bacteria filter goes between the long hose and the mask.
Clean equipment when on the go! Small enough for a carry-on, one 2 oz bottle of this concentrate makes 2 gallons of hospital grade germicide to thoroughly clean equipment.
