ASSEMBLING AND REPLACING THE HEPA FILTERS
A HEPA filter is designed for filtration of ultra fine particles. A clogged HEPA filter will reduce
the air flow thereby reducing the vacuum’s performance thus requiring replacement.
The life of the HEPA filters depends greatly on the use of the vacuum cleaner. It is
recommended that the HEPA filters be replaced once a year if the vacuum is used intensively
(daily). The filters can be replaced every two years if the vacuum cleaner is used less
frequently (two or three times per week)
WARNING:
If the vacuum cleaner is used for the recovery of toxic materials
proper clothing and the use of an appropriate breathing apparatus is
necessary when servicing the HEPA filter housing or any other
contaminated part of the unit.
