AIR PURIFIER SAFETY
This manual provides important safety messages regarding your electrical home appliance.
Always read, follow, and, save all safety directions.

heaters. • Do not block air vent openings.
• Never insert fingers or foreign objects into air vents.
• Do not place air purifier on a soft or unstable surface such as a bed or sofa.

Electrical and Safety Requirements — Reduce the risk of fire or electric shock.
Failure to follow these instructions can result in property damage, injury, or death. •
Do not connect unit to any electrical socket that is damaged.

• Do not plug the air purifier into an outlet controlled by a dimmer switch. • Do
not insert or pull out plug with wet hands, it may cause electric shock. • Do
not use an adapter. Do not use an extension cord.
• Use only in the proper electrical socket type. Socket type (voltage & hertz) can be found on
the unit’s back panel label. Incorrect socket use can damage/destroy the unit. • Do not exceed
the rating of the power outlet or connection device. May cause electric shock or fire due to
excess heat generation.
• Never try to take apart or repair the unit by yourself.
• Disconnect power immediately if you notice strange sounds, smells, or smoke. • Change
your filter at the recommended interval to avoid particle and dust buildup. • Ensure filter is
correctly installed before turning on unit. Do not run unit without a filter. • Do not cover the
unit or impede airflow.
• Do not drop the unit, as this can result in damage.
• Do not place heavy objects on the power cord and be sure the cord is not compressed as
there is danger of fire or electric shock.
• Do not spray insecticides or any other flammable sprays near the unit. It may cause
explosion or fire.
• WARNING! To reduce the risk of electric shock, this equipment has a polarized plug (one
blade is wider than the other). This plug will fit in a polarized outlet only one way. If the
plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact qualified
personnel to install the proper outlet. Do not alter the plug in any way.

USING YOUR AIR PURIFIER
PLEASE NOTE:
The BreatheSmart 45i has capacitive touch control panels. The buttons only operate
with a quick, light touch. Holding the buttons down will not activate the controls properly.
A chime will indicate that the control has registered your touch.
Operating Your Unit:
1. Plug your air purifier into a grounded outlet.
2. Touch Power Button in the center to start the air purifier. When your unit is on, the lights will
illuminate. To turn off display lighting, press the Power Button. To turn off the air purifier,
touch the Power Button again after the lights have turned off. The LIGHT Button can also
be used to control the display lighting.

3. The BreatheSmart 45i has a Color Ring around the Power Button indicating air quality, as
measured by the particle sensor.
COLOR
MEANING
Blue
Very low level of airborne particles detected
Green
Low level of airborne particles detected
Orange
Medium level of airborne particles detected
Red
Significant level of airborne particles detected
Purple
Very significant level of airborne particles detected
4. Press IONIZER to activate the ozone-safe ionizer. Activation of the ionizer enhances
your unit’s ability to remove airborne particles (similar to the way dust is attracted to a
TV screen). Press the ionizer button again to turn off.
5. FILTER life Indicator — There are three lights above the FILTER button: Green, Yellow,
and Red. The Green light will be illuminated for most of the life of the filter. The Yellow light
will come on shortly before your filter should be replaced. This is the ideal time to order a
new filter. The Red light will be illuminated when it is time to replace the filter.
6. After changing the filter, hold the FILTER button down for five seconds. This will reset
the Red light to Green.
7. Touch LIGHT to adjust display lighting (LO, HI, or OFF). LO dims lights by 50%.

KNOW YOUR AIR PURIFIER
Getting Started
When using the air purifier for the first time, we recommend that you use a higher fan speed,
such as speed three (3) or Turbo (T), for at least two hours to quickly clean the room’s air.
Then, we recommend that the air purifier run continuously on speed two (2) or three (3) to
maintain air quality, or set your unit to Auto mode.
BreatheSmart 45i Features
• True HEPA filtration captures dust, allergens, and airborne pollutants •
Four fan speeds to control air circulation
• Three settings to control display lighting
• Filter change indicator light keeps replacements on schedule
• Simple and intuitive touch button controls
• Auto-off safety feature when front cover is removed
Turn The Lights Off/On
To turn your unit’s display lighting off, touch the LIGHT button and select OFF. The lights will go
out, but the unit will continue running. To dim the lights on your unit, select LO.
CARE & MAINTENANCE
Cleaning Instruction
To avoid scratching the control panel, do not use abrasive/caustic cleaning solutions or
scrubbing pads. With the unit unplugged, dampen a clean towel lightly with soap and water
to clean the control panel, then dry gently with a soft cloth or paper towel. Glass cleaner
(e.g. Windex) is also OK. To avoid damaging electronic components, DO NOT allow liquid
to seep into the unit.
Prefilter Cleaning
The black mesh layer on the front of the filter, known as the prefilter, captures large dust and
hair. This layer is held on with Velcro®-like strips. This prefilter can be vacuumed in place to
maintain efficient operation of the unit.

Replacing The Filter
The Filter Indicator has three lights: Green, Yellow, and Red. The Green light will be
illuminated for most of the life of the filter. The yellow light will come on shortly before your filter
should be re-placed. This is the ideal time to order a new filter. You may order a new filter at
www.alen.com/ filters or by calling 1-800-630-2396. The Red light will be illuminated when it is
time to replace the filter.
The filters used in Alen Air Purifiers are not designed to be washed, cleaned, or otherwise
reused. Over time, the filters become overloaded with particles, decreasing their filtration
performance. We recommend regular filter replacements to extend the life of your air purifier
and maximize performance.
Reset the Filter Indicator
After replacing the filter, hold the FILTER button down for five seconds. The Red light will be
reset to Green.
Why You Should Replace Your Filter
• You purchased an Alen Air Purifier to improve the quality of your indoor air. • Changing your
filters on time is the only way to maintain an optimal level of air quality. • Excessively dirty
filters can compromise the level of clean air your air purifier can provide.

1. Always unplug the unit when installing a filter.

the cover near the top of the
intake vents with both hands to

bag to prevent dust from
re-entering the air.

WARNING! RISK OF ELECTRIC SHOCK - To reduce risk of electric shock, do not perform
any servicing other than that contained in the operating instructions.
TROUBLESHOOTING TIPS
How do I reset the filter indicator lights? I put in a new filter but the red or
yellow lights are still illuminated.
After changing the filter, RESET the filter indicator by holding down the FILTER button for five
seconds while the unit is ON. The light above the FILTER button should reset to green.
How do I find out what electrical specifications my unit needs? Please refer to
the rating label on the back of the unit. Here you will find your unit’s voltage, hertz, amps,
and outlet requirements.
Can I clean the filter?
The black mesh layer on the front of the filter, known as the prefilter, captures large dust and
hair. This layer is held on with Velcro®-like strips. This prefilter can be vacuumed in place or
replaced with a new prefilter to maintain efficient operation of the unit. No other layers or parts
of the filter can be washed, cleaned, or otherwise reused. Please replace the filter regularly to
maintain optimal performance.
