HEPA Filter
Replacing the HEPA filter should rarely be neces-
sary. However, if your machine has poor air flow
efficiency, and cleaning/replacing the canister fil-
ters does not remedy the situation, use the steps
below.
Wear safety goggles, respirator, and
protective gloves rated for operational
fumes and waste metal type when handling
filters. Take care to minimize amount of dust
allowed to become airborne, and prevent
spread onto hands and clothing.
