• Never try to take apart or repair the unit by yourself.
• Disconnect the power if strange sounds, smell or smoke comes from it.
• Do not try to change the lter during operation.
• Do not drop the unit, as this can result in damage.
• Do not place heavy objects on the power cord and take care so that the cord is not com-

KNOW YOUR AIR PURIFIER
When using the air purier for the rst time in a room, many prefer to use a higher fan speed
like speed three or four for a couple of hours in order to clean the room’s air initially. Then, it is
recommended that the air purier is left on to run continuously.
Features
• HEPA style ltration captures dust, allergens and airborne pollutants
• Activated Carbon layer traps light odors and chemicals (VOCs) from common household
products
• Ionizer charges particles, causing them to clump together for improved ltration
• Alen’s Smart-Sensor Technology automatically adjusts ltration levels based on level
of airborne pollutants. When the fan speed is set to AUTO, these sensors increase or
decrease the unit’s speed based on the level of odor or dust in the air.
• 4 fan speeds with an 8 hour timer to control air circulation
• Remote control conveniently manages features
• Wall-mountable for space saving or can be placed on the oor
• Digital display with simple and intuitive touch button controls
• Auto-off safety feature when front cover is removed
• Filter designed for easy replacement
• Lifetime Limited Warranty
CARE & MAINTENANCE
Replacing The Filter
The lters used in all of Alen Air Puriers are not designed to be washed, cleaned or other-
wise reused. Over time, the lters become overloaded with particles, decreasing their ltration
performance. We recommend regular lter replacements (at least every 6 months with normal
use) to extend the life of your air purier and maximize performance.
The black foam layer of the lter, known as the Pre-Filter, captures large dust and hair. This
layer is held on with Velcro®. Once removed, the Alen Pre-Filter can be washed or vacuumed
to maintain efcient operation of the unit.
For optimal performance, it is recommended that the air purier is left on to run continuously.
Under this type of usage, lters will need to be replaced approximately every six months.
Why You Should Replace Your Filter
• Fullls the terms of Alen’s warranty which states that the lters are required to be changed
on a regular basis in order to prevent excessive stress on the unit.
• You have bought an Alen Air Purier to improve the quality of your indoor air. Changing
your lters will maintain the level of air quality you require. Excessively dirty lters can
compromise the level of clean air your air purier can provide.

How To Replace The UV Light
1. Before replacing the UV light, please unplug the unit.
2. With the front of the unit facing up, pull up the lower end of the inlet grill and push it
toward the display panel at the top of the unit, then remove it.
3. Remove the lter by lifting the pull string.
4. Unscrew the screws on the lampshade with a screwdriver, and then remove the lamp-

TRoUbLEShooTINg TIPS
How do I reset the lter indicator light? I put in a new lter but the light is still
illuminated.
After changing the lter, RESET the lter indicator by holding down TIMER while the unit is ON
until the illuminated clean indicator light disappears.
Can I clean the lter?
The black foam layer of the lter, known as the Pre-Filter, captures large dust and hair. This
layer is held on with Velcro®. Once removed, the Pre-Filter can be washed or vacuumed to
maintain efcient operation of the unit. No other layers or parts of the lter can be washed,
cleaned or otherwise reused. Please replace the lter regularly to maintain optimal high perfor-
mance.
How can I tell if my UV lights have burnt out?
Turn on the UV lights by pressing UV and set the fan speed to 1. Make sure the room that the
unit is placed in is dark. Look through the top of the unit where the air blows out to see if there
is a blue glow. This glow is quite faint, so you may need to press the UV button on/off several

12 Helping People Live Better
times to see if you notice a difference. If there is no glow, then the UV lights have burnt out
and need to be replaced. Visit www.AlenCorp.com or call 1-800-630-2396 to order a replace-
ment UV light. UV lights are like normal light bulbs and will last approximately 9 to 12 months
when operated continuously.
