According to the U.S. Environmental Protection Agency, levels of air
pollutants may be two to fi ve times, and in some cases, more than 100
times higher that outdoor air levels. The average cubic foot of indoor air
contains 20 million particles, more than 95% of which are smaller than
1 micron (a micron is 1/25,000th of an inch). Most fi lters simply can’t
capture these small particles. And to effectively clean the air, submicron
particles must be removed.
The AlpinePure ET effi ciently captures an unparalleled 97% of these
particles down to 0.3 microns. Its superior effi ciency is the result of
electronic polarization and activated carbon. The fi lter works by assign-
ing polarity to all the particles in the air as well as to the fi berglass media
in the air cleaner. These polarized particles become like small magnets
clinging to each other and to the air cleaner media.
The chart below compares a high effi ciency media fi lter effi ciency to the
AlpinePure ET effi ciency with various particle sizes:
Unlike typical electronic air cleaners, it does not create ozone or produce any nuisance zapping noises. This air
cleaner can be installed easily in your new or existing system without ductwork re-confi guration. It is simply installed
in the 1-inch fi lter rack of your geothermal unit.
Cleaning Procedure
The only maintenance that is required is to simply replace the fi lter media about every 2-4 months. To clean the fi lter
and replace the media, follow these steps:
• Turn off the power to the unit (at the breaker).
• Open the fi lter access door on the side of the unit.
• On the Powerhead of the air cleaner, unplug the adapter cord. Make sure that the jack does not touch any
metallic or grounded surfaces which could result in possible damage to the unit.
• Remove the air cleaner. Brush or vacuum dust and debris from the external wire surface of the air cleaner.
• Carefully open the air cleaner by moving the clips. Remove the old (blue) media pad and discard.
• Position a new pad fl at and in the center of the frame.
• Close the air cleaner, and clip shut.
• Plug the adapter cord into the Powerhead of the air cleaner.
• Reinstall the air cleaner into the fi lter rack. Restore power to the unit.
Note:
Because of variations in humidity and temperature, a new media pad may arc or snap slightly when fi rst installed. This is
normal and should cease after a few hours of operation. If the arcing persists and/or is rapid, remove and re-position the fi lter
pad. If the arcing continues or if the power indicator light on the Powerhead is dim or out, call your dealer. Only AlpinePure
replacement media pads can be used in the AlpinePure ET. Your dealer can supply you with a quantity of replacement media
pads.
Keeping your fi lter clean is one of the most important things you can do to ensure that your geothermal unit oper-
ates at its peak effi ciency and to minimize the potential for premature failure.
