CLEANING & MAINTENANCE
Keep the Therapure ® 240 functioning properly by cleaning the permanent HEPA-type filter each
time the Clean Filter Indicator Light turns on. More frequent cleaning will be necessary if the unit
is located in an area with a high level of airborne contaminants (excessive amounts of smoke, pet
dander, etc.).
NOTE: Always make sure the Therapure ® 240 is turned off and unplugged before cleaning.
» Vacuuming will restore performance of the permanent HEPA-type filter. However,
the filter may appear stained. This is normal and does not affect performance in any way.
» Do not use water or any household cleaners or detergents to clean the permanent
HEPA-type filter.
» The inlet grill may be cleaned (after unit is turned off and unplugged) with a vacuum
or a slightly damp cloth.
Cleaning the permanent HEPA-type filter
1. Release the inlet grill by pressing on the locking latch (see diagram of Main Parts).
2. Remove the inlet grill from the unit as shown below.
3. Grasp the left and right frames of the permanent HEPA-type filter through the indentations on
the sides of the filter enclosure and remove the filter.
4. To clean the permanent HEPA-type filter, use the brush or crevice attachment with a vacuum
cleaner. Run the attachment along the inlet and outlet side of the filter, cleaning between the
crevices as much as possible. Do not use water or any household cleaners or detergents to
clean the permanent HEPA-type filter.
5. Once the permanent HEPA-type filter has been cleaned and checked for any possible damage,
replace the filter back in the reverse direction described here. Plug in the unit and hold down
Timer + Power On button for 3 seconds. The clean filter light will go off and your cleaning
maintenance is done.
Exposing the Therapure ® 240 to candle/oil/fireplace soot and smoke is not recommended
and will require more frequent cleaning.
