Maintenance

The only maintenance required is cleaning the filters.

It’s extremely simple:
Outlet air filter (rinse under running water and dry thoroughly before reinserting)
Inlet air filter (if not too clogged, it can be cleaned with a vacuum cleaner)

When the filters can no longer be cleaned, it’s best to replace them immediately to maintain the proper level of filtration.
