Changing the HEPAtech
When the HEPAtech

the HEPAtech
filter. Refer to Filter Life Counters for additional information, pg. 8. This is a reminder that
you should check the filter and replace it if necessary. The proper time to change the filter
depends on usage and the environment. Generally, if you notice a decrease in air output
or an increase in noise at any time during normal operation, the filter may be clogged.
Replace the filter to return to normal operation.
