CLEANING & MAINTENANCE
Keep the Therapure ® 640S functioning properly by cleaning the cleanable HEPA-type Filter every
four weeks of use. 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.).
Exposing the Therapure ® 640S to candle/oil/fireplace soot and smoke is not recommended and will
require more frequent cleaning.
NOTE: Always make sure the Therapure 640S is turned off and unplugged before cleaning.

Vacuuming will restore performance of the cleanable 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 cleanable
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 cleanable 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 cleanable HEPA-type Filter through the indentations on
the sides of the filter enclosure and remove the filter.
4. To clean the cleanable 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 cleanable HEPA-type Filter.
5. Once the cleanable 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
the ION + UV/VOC button for 3 seconds. The clean filter light will go off and your cleaning

CLEANING & MAINTENANCE
Cleaning the Pre-Filter
1. Release the air inlet grill by pressing on the
locking latch.
2. Gently remove the pre-filter from the air inlet grill.
3. To clean the pre-filter, simply submerge in warm
soapy water. Gently lift and submerge the
pre-filter several times until it is clean.
4. Rinse the pre-filter with clean water and allow it
to dry completely before placing it back to the
air inlet grill.

Cleaning External Surfaces

1. Turn off and unplug unit.
2. Use a washcloth slightly dampened with
a little water and dishwashing soap
to wipe the outer case surfaces.
3. Do not allow water to slip into the internal parts
as this could damage your unit and result in
electrical shock and injury to you.
4. Allow the unit to thoroughly dry before use.
UV Lamp
The lifetime of the UV lamp is up to 12 months of
continuous, effective operation. After this time, the
bulb may remain illuminated, but its effectiveness is
greatly reduced. For maximum effectiveness,
please replace the UV bulb annually.
If the lamp stops functioning or needs
replacement, please visit our web site at
www.envionproducts.com to order a
replacement lamp. Or call 1.800.875.8577.
Caution:
•
Do not touch the glass part of the lamp. Oil
from fingertips will decrease the effectiveness
of the lamp.
•
Never operate the unit without a filter or with
a damaged filter. UV lamp cover must be
installed at all times. The UV light from the UV
lamp will result in severe damage to eyes and
could cause blindness.
UV Lamp Notice Warning:
UV Light is harmful to bare skin and eyes and can
cause temporary or cleanable loss of vision.
Never look directly at the UV lamp while it is
illuminated-doing so could cause loss of vision!
