The polypropylene hydrophobic filter (MLA 0110 In-Line Filter) connects to the gas sampling port on the front-panel of the ML206 Gas Analyzer. The filter is used in conjunction with the MLA6024 Desiccant Cartridge and MLA0343 Drying Tube to remove any moisture from the expired breath before it enters the Gas Analyzer.
It is recommended that the In-Line Filter is changed every time the desiccant cartridge and drying tube are replaced. The desiccant material in the cartridge contains silica gel that changes color from blue to pink when the cartridge needs to be replaced.
