Air Filtration
The Santa Fe Rx is equipped with a MERV-11 air filter. An optional HEPA filter is available with the use of the filter housing. The
MERV-11 air filter should be checked and replaced every three to six months while the HEPA filter could last up to 3-4 years or
more providing the MERV-11 filter is changed regularly. Operating the unit with a dirty filter will reduce dehumidifier capacity
and efficiency. Bulk activated carbon granules are also available for purchase and can be sprinkled over the top of the
standard MERV-11 filter on the inlet of the dehumidifier. To order more filters, visit www.Santa-Fe-Filters.com.
Changing the Standard MERV-11 Air Filter
For greatest filtration and efficiency of the Santa Fe Rx, it is recommended the the MERV-11 filter be replaced every
three to six months.
Step 1 - Undo the three latches. Remove the top
of the unit by sliding it forward. Next, lift the front
edge up first, then the back. Remove the filter by
pulling it up and out.
Step 2 - Insert the new filter by gently placing it back
into the top of the unit. Be sure the arrows on the filter
are pointing down towards the unit. Reinstall the top
cover by sliding the back in first, then the front. Then
slide it all the way back until it is securely into place.
CAUTION!
MAKE SURE UNIT IS OFF BEFORE CHANGING THE FILTER. FAILURE TO FOLLOW FILTER HANDLING
INSTRUCTIONS MAY RESULT IN IMPROPER FUNCTION OF THE DEHUMIDIFIER AND CAUSE
PREMATURE FILTER WEAR OR UNIT DAMAGE.

Changing the Optional Filters
An optional filter housing is available that attaches to the back of the machine
and adds 6-1/2” to the units’ depth. It allows the choice of using a MERV-14 filter
(need two) or a HEPA filter. These filters are accessible by removing the 4 screws
from the filter frame top cover.
The optional filters have long lives when prefiltered by the standard MERV-11
filter; they can last many years in certain conditions. How long they last
can, however, vary widely depending upon the following: unit run time, air
contamination level and standard inlet filter cleanliness. Given the expense
of the optional filters, it can be costly to change them prematurely. The
following test helps determine when they should be changed.
Air exiting the bottom rear of the unit enters the filter frame, then passes
through the optional filter and into the room. If the filter is dirty, air pressure
builds up before the filter. To check this pressure, remove the plastic plug from
the filter frame top; you will feel air coming out of the hole with the unit running.
Place the ping pong ball that came with the filter frame on the hole and let go
(any marked, regulation sized ping pong ball will work). If the ball does not move
or only bounces slightly and does not spin continuously, the filter is clean enough
for continued use. If the ball floats above the hole and starts to spin and perhaps
wobble within 30 seconds, the filter needs to be changed.
See the instruction sheet that comes with the optional filter to learn how to change
the filters.
