AIR CLEANING SYSTEMS and INDOOR AIR QUALITY
Why should I be concerned with the air
I am breathing?
Sometimes it may be better to not know what is in the air, but since you are reading
this we’ll share what the leading health agencies are reporting.
First a little background on particulate matter. The particles that oat through the
air are a combination of solid particles and liquid droplets. Particles are measured
in microns, where a micron is one millionth of a meter (10-6 meters) and is also
called a micrometer. The particles that we can see with the naked eye are those
larger than 50 microns. A human hair is approximately 100 microns in diameter. The
airborne particles that result in allergies or impact our health are much smaller and
not visible with the naked eye. Mold spores and pollen particles are from 2 to 10
microns. At times they can be visible but this is when there is a large concentration
massed together.
Before we get to the types of particles in the air, let’s review the particulates in the
air that are 10 microns and smaller and why we need to care about them. Particles
10 microns and smaller can pass through and deposit in our respiratory system
and are referred to as respiratory particulates. The concern here is that the smaller
particles can be breathed deep into the lungs. These smallest of particles tend to
stay suspended in the air longer than very large particles such as dust so there is a
greater chance for inhalation. They can also serve as a vehicle to transport contaminants deep into the lung area.
Particles 5 microns and larger are trapped in the throat and nasal regions, particles
between 1 and 5 microns are trapped in the trachea (leads to the lungs) and larger
lung branches and particles less than 1 micron in size go to the alveolar area which
are the tiny air sacs in the lungs. This is where the exchange of oxygen and carbon
dioxide takes place.
The primary composition of our air is made up of Nitrogen, Oxygen, Argon and
Carbon Dioxide. All of this is obviously invisible to us. Unfortunately, the respiratory
particulates are also not visible to the naked eye. Here is a summary of the common “pollutants”:
Bacteria: 0.2 - 5 microns
Mold spores: 2 – 10 microns
Pollen: 10-20 microns
Dust mites: 300 microns (feces 20 microns) – most common allergen in US
Viruses: 1 micron and smaller

AIR CLEANING SYSTEMS and INDOOR AIR QUALITY
How do we get rid of these micro particles? As we have said, the most effective tech-
nology to safely remove these particles is with HEPA ltration. A true HEPA lter is
rated at removal of 99.97% of particles that are 0.3 microns and larger. An interesting
fact is that the effectiveness of HEPA lters increases over time which is the opposite
of the ionic or lter-less technologies as those plates get dirty the ability to charge and
collect particles decreases. Also, since these particles can be easily breathed into our
respiratory system, the last thing you want to do is have to clean them regularly and
come into contact with the stuff you’re trying to avoid. In addition, HEPA lters also
perform better at the removal of particles smaller than 0.3 microns.
To kill bacteria, UV lamps have been proven effective. The Alen T300 and A375UV
specically address these concerns as well as offer HEPA ltration for mold spores,
pollen, dust, etc.
We are proud to announce the latest line of
Dehumidiers to join Alen Indoor Air Quality products.
To give you a brief understanding about the importance of source control of MOLD,
below is an outline that explains why the use of a dehumidier in your room/indoor
environment is vital to the source control.
What is SOURCE CONTROL?
1) Source of moisture/humidity
2) Temperature Control and
3) Filtering the air
MOLD loves humidity. An indoor environment with 65% or above in humidity is a very
fertile place for mold. So, use a dehumidier and control the humidity in the air.
Please visit the www.alencorp.com dehumidier section for more information about
the models of dehumidiers that Alen manufactures.

HOW TO ASSEMBLE AND USE
Reminder: Make sure the HEPA lter is properly installed before use.
Where to locate:
1) Keep the unit in a place at least 2 yards away from the TV set, radio, etc.
to avoid interference.
2) Do not blow air directly into the air purier.
3) Keep both sides of the unit more than 6 inches away from the wall.
4) Do not place the unit where the air inlet or outlet grill could come in
contact with a curtain.
5) Place the air purier in a well-ventilated location of the room.
6) Placing the unit close to the source of the air pollution may further improve
indoor air quality.
Setting the Control Panel for A375UV Ultra
1) Plug the unit into an electric outlet, the unit will be ready to run. Press the On/Off
button to start running, re-press it to stop.
2) When the air purier is turned on the fan will run at medium speed for 3 seconds
before running at low speed (default speed). Press the speed button each time,
the fan speed will cycle.
3) While the air purier is on, press the TIMER button to the desired run time
(hours). The air purier will automatically turn off once the timer has counted
down to zero.
4) Press the ion key to turn on the ionizer while the fan is running, press it again to
turn off the ionizer.
5) Press the UV lamp button to turn on the UV lamp, which is used to help to kill
harmful bacteria in the air. Press it again to turn off the UV lamp.
6) When the HEPA replacement light is lit up the HEPA lters needs to be replaced.
7) When the unit runs in auto mode, the dust and odor sensors can sense the air
quality in the room and automatically adjust the fan speed. The particle sensor

8) The odor sensor can also detect cosmetic and aerosol odors. As the odor level
increases, the odor indicator’s bar moves from right to left. If the air purier is
moved to a new location, the sensor needs a short period of time to adjust to the
new environment. During this time the indication of air cleanliness may not reect
