Replacement air filter for the Guardian Air Filter, the filter helps to remove dirt, rust and other contamination in the breathing gas. When replacing the filter, remember to fill with some distilled or bottles water to increase air moisture and reduce ‘dry throat’.

The charcoal & wool layers remove trace particles of rust and dust as well as odours.  A molecular sieve absorbs moisture, and help spread it to increase humidity into the breathing gas.  The filter is compatible with Nitrox upto 40%, DO NOT USED WITH HIGHER OXYGEN PERCENTAGES!
