For efficient operation, the filters must be
changed on a regular basis. If you notice a
reduction in air flow from the system, check the
filters.
Replacing the HEPA Filter and Prefilter
1. To access the filters, turn the Air Cleaner
OFF at the switch and open the Rear, Bottom
Filter Access Door.
2. Carefully remove the filters to avoid spilling of
collected contaminants. Dispose of filters in a
plastic
bag
household trash.
3. Remove the plastic from the new filters
before installing. Discard plastic safely. Take
care not to damage the filters. Hold by the
filter frame only.
4. Date the replacement filter in the space
provided.
5. Place the filters in their appropriate track with
the arrows pointing up.
6. Use genuine replacement filters only. Call the
original installer for parts.
Note: When the filters are new, you may notice a
new smell from the system. This is normal and
will dissipate within a few hours.
Prefilter (#DM900-0855): This must be replaced
every 3-6 months. A clean Prefilter will increase
the life of the HEPA Filter and improve airflow.
HEPA Filter (#DMH4-0400): Replace every 2-3
years. The life of this filter depends on the
amount of contaminants in the air and the
frequency in which the Prefilter has been
changed. Renovations in the home that create
wood, drywall dust or similar contaminants will
shorten the life expectancy of the HEPA filter.
Note: Handle the HEPA filter by the frame only.
The paper is fragile and a puncture or tear will
reduce efficiency.
