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 float 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 contam- inants 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 com- mon “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 4 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 filtration. A true HEPA filter 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 filters increases over time which is the opposite of the ionic or filter-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 filters 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 specifically address these concerns as well as offer HEPA filtration for mold spores, pollen, dust, etc. We are proud to announce the latest line of Dehumidifiers 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 dehumidifier 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 dehumidifier and control the humidity in the air. Please visit the www.alencorp.com dehumidifier section for more information about the models of dehumidifiers that Alen manufactures. 5 HOW TO ASSEMBLE AND USE Reminder: Make sure the HEPA filter 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 purifier. 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 purifier 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 purifier 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 purifier is on, press the TIMER button to the desired run time (hours). The air purifier 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 filters 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 higher the dust particle level, the further the indicator bar moves from left to right. 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 purifier 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 reflect the real air conditions. 9) FILTER REPLACEMENT: When the filter is replaced, press the TIMER button for 5 seconds to RESET the filter replacement indicator light. NOTICE: If the air quality is extremely poor, you may replace the HEPA filter before all the bars are lit. 7 REPLACING A375UV BULB Particle & Particle & odor sensor odor sensor UV Bulb L. screw R. screw Metal Bar across the UV bulb Replacing the UV Bulb 1) Before replacing the UV bulb, please unplug the unit and remove the cover. 2) Lay down the unit and pull up on the lower end if the front cover and push toward the display panel at the top and remove. 3) Remove the HEPA filter by lifting the pull strings on either side of the filter. 4) Remove the metal bar across the UV bulb by removing the R. & L. screws. 5) Hold the edge of the UV bulb and gently twist a quarter turn until it unlocks from the socket. Pull the pins out of the side of the socket, one at a time. 6) Remove the UV bulb. Gently handle the new UV bulb on the ends only. 7) Gently insert the UV bulb into the socket and twist a quarter backward and put back the metal bar with the screws. 8) Reinstall the cover by hinging at the top and pressing the bottom of the cover to snap into place. 8 A375UV FEATURES AND SPECS Features 1) Pre-filter - Traps larger dust particles. 2) HEPA Filter with carbon - Removes particles as small as 0.3 microns from the air at 99.97% effectiveness. 3) Activated Carbon Filter reduces odor. 4) Built-in Ionizer Releases the property concentration of negative ions to keep the air fresh. 5) Fan speed settings & 12 hours times - 4 fan speeds. 6) Filter replacement Indicator - notifies you when it is time to replace the filters. 7) Digital Display - displays the operation more of the unit. 8) Soft touch button control - sensitive soft touch buttons, easy to operate. 9) UV bulb sterilization - the germicidal UV bulb is used for bacteria control. 10) Photocatalyst Filter - the photocatalyst filter is used to decompose odors in the air such as formaldehyde, alcohol and ammonia, and kill viruses and bacteria in the air too. 11) REMOTE CONTROL - the set up button is used to set the three modes: On Time, Off Time and Fan Speed.
