PORTA-NEB FILTERS - 4 PACK
Pack of 4 replacement air inlet filters for the Porta-neb and Freeway Lite II systems.
The filter which cleans the air that you use during treatment, gets dirty over time. If it gets blocked the Porta-neb does not work properly.
As soon as the air inlet filter no longer looks white and clean it should be changed (usually after three months). Filters will need to be replaced more frequently if you have smokers in your home.
To change the air inlet filter, unscrew the plastic dome, take out the old filter and put in a new one. Then screw the dome back on.
Warning: The air inlet filter must not be cleaned in any liquids and should be replaced if dirty. Do not operate the unit without the filter or with a clogged (dirty) filter. Operating the unit with a dirty filter can impair proper operation and cause damage that is not covered by the warranty.
