ASIET Air Purifier FAQ

ASIET Air Scrubbers cause a photocatalytic reaction by using UVC lamps and catalyst coated filter media to make the air hostile to mold spores, pollen, bacteria, virus, VOC’s and smoke. Coatings on the lamps prevent the production of ozone during this process.

- Add it directly to any existing heating system.
- Available as portable stand alone unit.
- Install directly to most roof top systems

Costs will vary with each application, but much like your present HVAC system, it depends on how much cubical area you are treating and how you want to do it. An ASIET representative will be happy to discuss the situation with you, explain options and the cost of each option so that you can make a decision best suited for you. Maintenance costs are relatively low, but you can expect to continue to replace air filters on your HVAC system. Lamps will need to be replaced on an annual basis and reactor pads may need replaced every three to four years. If smoking is allowed in your home or facility, the lamps may need to be wiped with alcohol at ninety day intervals. Ballast and switches should be replaced as needed, just as you would in maintaining a florescent light fixture.

Not at all. Depending on the configuration of the system you choose, it either becomes a part of the HVAC system or works with it. In either case, it will enhance the performance of the HVAC system over time.

- No, adding ASIET Environmental equipment to your existing heating system   disinfects and cleans the airflow as well as the existing air handling system will   improve the systems overall performance.

04.

Is the ASIET equipment Green Energy and are there any energy savings to be gained with this equipment?

Yes, Over time the reactor pads and ducts will become cleaner with the continued use of the ASIET Air Scrubbers and the original designed efficiencies of your HVAC equipment will be regained. Facilities with economizers on their HVAC equipment can reduce the amount of fresh air needed because ASIET Air Scrubbers keep the indoor air fresh and healthful, reducing the need for bringing in hot or cold air and having to change it’s temperature for the buildings occupants.

- Yes, ASIET SYSTEM cleans up the indoor environment and reduces overall energy   consumption in the process.
- Reduces amount of energy by eliminating airborne particulates and contaminants.
- Less energy to heat or cool air than microbial sized solids in the air.

05.

5. What about VOC’s in the air in my buildings and home, are they harmful and can ASIET equipment help?

Volatile Organic Compounds (VOC's) in our enclosed environments come from many sources. Plastics, fabrics, finishes, processes such as copying and printing. Nearly all man made products contain chemicals that tend to drift away as gaseous vapors. The very word ‘volatile’ describes this tendency to change to a gas from a solid or liquid state. Many volatile compounds in the air are detectable as odors, but many are not odorous and give us no warning of their presence. Many voc’s are harmful to us in that some are known to be carcinogenic, others may attack or weaken our immune systems. Some are just irritating or make us ill at the time of exposure. Other sources of VOC's are natural in that VOC's can be produced by mold and bacteria. Whatever the source, ASIET Air Scrubbers drastically reduce their presence so that the air we breathe is not doing damage to us.

- VOC’s are the most difficult to detect and measure, yet are some of the most   harmful to human and animal health.
- VOC’s consist of organic particulate as well as airborne chemical spills
- VOC removal or conversion is equally important to biological and particulate   removal.
- VOC’s can affect the nervous and immune systems.
- VOC’s causing loss of productivity, nausea, long-term chronic illness, cancer or   death in some people.

06.

What are the most common types and forms of mold found in sick buildings?

Studies by AIR Quality Sciences, Inc. of Atlanta, GA identify Cladosporium, Penicillium, Aspergillus and Alternaria to be the most common molds found in problem facilities.

- Recent studies have identified Cladosporium, Penicillium, Aspergillus, and Alternaria   to be the most common molds found in problem facilities. Based on testing   performed by Air Quality Sciences, Inc. Atlanta GA

07.

Why do I have mold in my building?

Mold spores are in the air, all around us, all the time, outdoors and indoors. Under normally lighted, dry and temperate conditions the spores remain dormant. Occasionally areas in our buildings for one reason or another become damp and remain that way enabling mold spores that were already there to begin growing. If other conditions are right, such as temperature and lack of lighting and a ready organic food source such as paper, wood, fabric, shed skin cells, pet dander or anything that once lived (such as decaying plants) mold growth can be astonishingly rapid, pushing airborne mold spore counts much above normal.

- Molds and dust mites thrive in areas of high humidity. Mold grows on organic   materials such as paper, textiles, grease, and dirt and soap scum. Mold spores float   throughout the building structure, forming new colonies where they land. Dust mites   thrive on dead human skin cells and in textiles such as bedding, carpeting, and   upholstery. When these textiles are disturbed during vacuuming, making beds, or   walking on carpet, the dust particles become airborne. Pollen, plant material that   enters through windows or on pets and animal dander also become airborne when   disturbed. Infectious diseases caused by bacteria and viruses are generally passed   from person to person through physical contact, but some circulate through indoor   ventilation systems

08.

Are there any health effects caused by mold?

When flourishing mold begins it’s natural reproductive cycle and begins to produce more mold spores, the levels of mold spores in our enclosed environments begin to increase in numbers. Then we begin to notice the adverse health effects of the higher mold spore counts. The nature and intensity of the adverse health effect vary widely depending on the type and amount of mold spore, and one’s immune levels and tolerance levels. Allergic reactions are the most common health problems associated with biological pollutants such as mold. Symptoms often include watery eyes, runny nose and sneezing, nasal congestion, itching, coughing, wheezing, difficulty breathing, headache, dizziness and fatigue. We seldom realize that ‘where we live’ or ‘where we work’ may hold the source of our current illness.

- Allergic reactions are the most common health problems associated with biological   pollutants. Symptoms often include watery eyes, runny nose and sneezing, nasal   congestion, itching, coughing, wheezing and difficulty breathing, headache,   dizziness and fatigue. Dust mites have been identified as the single most important   trigger for asthma attacks.

09.

What is formaldehyde and what is it doing in my home and building?

Formaldehyde is a chemical compound that has been around for many years now, and industry has found many uses for it. It is a good preservative and has been used in many adhesive (glue) formulas. Many of the building industry products and furnishings industry products contain formaldehyde. The problem with this is that formaldehyde has a high volatility level and escapes from the products we build and furnish our homes and workplaces within the form of a gas. This gas forms part of the odor we associate with ‘new’ such as the smell of ‘new’ furniture or a ‘new’ car. However, many of formaldehyde’s characteristics that make it a good thing in industry make it a ‘bad thing’ for us to breathe. ASIET Air Scrubbers deal with this airborne VOC quickly by chemically reducing it to harmless compounds.

- Formaldehyde is a chemical that is released into the air as a foul odor. It has a   number of useful properties; it's a good preservative and makes an excellent   adhesive. Therefore, it is used widely in the building and furnishings industries. It is   also found in small amounts in some textiles as an anti-wrinkle agent.

10.

Why are the best air filters alone not enough to control mold and other airborne contaminants?

Normal air filters trap larger particles in the airstream but do not catch the much smaller particles and organic contaminants typically found in a building’s air envelope. High Efficiency Particulate Air (HEPA) filters will catch many of the smaller particles including virus, bacteria and mold spores, but they are expensive to replace (often), require higher horsepower motors to force the air through, and can themselves become the source of additional indoor air pollution by trapping colonies of bacteria that release poisonous mycotoxins (gases). Filters also do nothing for problems lurking further downstream in the chill water or evaporator reactor coils where moist dark conditions encourage the growth of mold and bacteria. Air filters do not ‘treat’ the air but only capture organic particles (and some inorganic) that are in suspension in the air, such as lint, dust, pet dander and do nothing at all with gases unless an activated charcoal filter is in use and it also requires frequent changes. Filters certainly have their place, but the do not treat the air and neutralize it as do ASIET air scrubbers.

- Air filters, including High Efficiency Particulate Air (HEPA) filters have been used for   many years in heating, ventilating, and air conditioning (HVAC) systems. Some are   very effective in trapping particles like pollen and dust. Unfortunately they cannot   trap minute particles like viruses, most bacteria, and mold spores that breed in the dark moist interiors of HVAC cooling reactor pads and drain pans, which are located downstream of filters. There is also a problem with fungal spores growing and multiplying in damp HEPA filter material. When this happens, the filter can actually increase the number of Mycotoxins spores in the room or the building. Ultraviolet germicidal devices radiate powerful UVC light onto the reactor pads and drain pans inside the air-conditioning system where mold and other odor and disease causing organisms breed. The UVC light inactivates and gradually vaporizes this microbial   growth, removing it from the air, thus accomplishing what the air filter cannot do.

11.

What about ultraviolet light alone?

Placing ultraviolet light in the HVAC system near the cold water or evaporator reactor pads is effective on biologicals (mold, bacteria) growing where the light is. The UV light will clean up that spot where the light shines but will have no effect on, hazardous materials in the air, or sources of hazardous biologicals in the building. ASIET equipment treats the air and the air then treats every corner and recess of the building.

- Installing UVC lights alone is not the best solution due to short (exposure) dwell   time and air speeds in air systems. UVC bulbs without reactor shields need to be in   very close proximity to surface needing cleaning for an extended length of time.

12.

What is UVC light?

UVC light is part of the sun’s electromagnetic spectrum. Ultraviolet light is just beyond the violet band of the visible part of the spectrum, and is usually designated in three wavelength groups by the letters A, B, C. The UVC band being the part of the spectrum responsible for sunburns, paint flaking, plastic becoming brittle, decomposition of plant and vegetable matter, and the sun’s purifying effect on the earth. Through the use of UVC light and photocatalysts found in nature, ASIET is able to replicate one of the earth’s natural purifying process and bring it into our indoor environments.

- Ultraviolet light represents a portion of the sun's electromagnetic spectrum. It is the   wavelength band immediately beyond the violet end of visible light. The UV range of   the spectrum is characterized by wavelengths between 100 and 400 nanometers   (nm).

13.

How often do the UVC lamps need to be changed in the ASIET equipment?

Annually if they are under constant use, somewhat less often if only used periodically. The lamps are rated for about 9000 hours of effectiveness. ASIET recommends cleaning the lamps each time filters are changed and reactor pads are rotated.

- Cross Rode’s Technology recommends cleaning your bulbs every time you rotate   reactor shields. Bulb life varies between 9,000 to 12,000 hours which is about one   year of constant use.

14.

Is ozone an air purifier or an indoor air contaminant and pollutant?

Ozone is an unstable oxygen molecule with three, instead of two oxygen atoms combined. The third atom is loosely attached and will readily combine with other molecules to form a volatile organic compound for instance. Ozone is an effective deodorizer and purifier and has many beneficial industrial applications, but according to the U.S. Food And Drug Administration “Ozone, to be effective as a bactericide or deodorizer, must be present in concentrations far greater than can be safely tolerated by man or other animals.” According to the U.S. Environmental Protection Agency, ozone is a toxic gas with vastly different chemical and toxicological properties than oxygen. When inhaled it can damage the lungs and relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone has been used effectively for years to clean wastewater. In water containing organic material it is used up rapidly – before it reaches the air. In recent years some companies have been ordered to remove their air purifiers from the market because of the excessive amount of ozone the produced. ASIET air scrubbers use non-ozone producing UVC lamps to minimize the possibility of producing ozone.

- Ozone is being marketed by some as an air purifier, often in conjunction with UVC. It   is true that UVC will produce ozone at low frequencies. According to the U.S. Food   and Drug Administration: "Ozone, to be effective as a bactericide or deodorizer, must   be present in concentrations far greater than that which can be safely tolerated by   man or other animals." According to the U.S. Environmental Protection Agency,   ozone is a toxic gas with vastly different chemical and toxicological properties than   oxygen. When inhaled it can damage the lungs and relatively low amounts can   cause chest pain, coughing, shortness of breath, and throat irritation. Ozone has   been used effectively for years to clean wastewater. In water containing organic   material, ozone is used up rapidly -- before it reaches the air.

15.

Why should I concern myself with biological issues?

Regardless of whether you realize it or not we are all breathing cleaning chemicals, pet and human dander as well as decomposing organic matter in our indoor environments. Conventional filtration systems, even HEPA filtration, does nothing to elimination viruses, bacteria, and other pathogens from the air we breathe.

What All Biological Issues Do We Fix?

16.

I am concerned about the biological contaminants in my home and workplace, what can I do to reduce my exposure.

- By installing ASIET’ equipment in your heating system you can start eliminating   biological contaminants and or pathogens. There are no practical tests for biological   contaminants for use by non-professionals. However there are signs to watch for.   You can sometimes see and smell mold colonies growing on surfaces. Mold growth   should be suspected whenever and wherever there are water stains, standing water   or moist surfaces. Although we don’t do air testing we have names of several firms   throughout United States we are always happy to share these firms contact   information with anyone concerned about their air quality.

17.

Why don’t the UVC bulbs in the ASIET equipment produce ozone?

- All of the manufactures of UVC bulbs used by Air Scrubbers International   Environmental Technologies are designed to block the Ozone from any and all bulbs   we allow in any equipment we manufacture.

18.

How does the combination of the proper UVC bulbs and custom coated Reactor shields control airborne threats?

- ASIET’S photocatalytic oxidation technology is both superior in efficiency and   effectiveness to existing filtration or UVC alone. Some other processes utilize ozone,   UV, activated charcoal, HEPA, electrostatic, or ionization filters. ASIET technology   combines the best of these processes - rotatable reactor shields and UV irradiation   with catalytic filters to truly cleanse, not just filter, the air.
- HEPA filters remove smaller particles than do the rotatable shields, however, HEPA   filters require more energy to operate and have no germicidal action.
- Activated charcoal removes odor by adsorption and need frequent changes but has   no germicidal action.
- Ionization chambers place a charge on particles causing them to cling together on   filters, air duct components, and walls but have no germicidal action.
- UV lights have a germicidal action and have cured sick building syndrome. However,   UV light alone is not as effective as is the combination of UV and metal oxides such   as TiO2.

19.

What scientific proof is there that the ASIET equipment really works?

- Texas Tech University's Department of Biological Sciences evaluated UVC assisted   reactor powered equipment for germicidal effectiveness in laboratory studies. The   equipment tested was a special research machine that contained UV-C germicidal   lamps and photocatalytic reactors. It has long been established that irradiation from   UV-C lamps kills bacteria by direct exposure. Equipment was developed to test the   hypothesis that E. coli exposed to an air stream treated with UV-C light and   photocatalytic reactors would be killed at a faster rate than would E. coli exposed to   an air stream not treated with photocatalytic reactors. E. coli in both test and control   conditions were maintained in the dark. The special test machine developed for   Texas Tech exposed an air stream to photocatalytic reactors irradiated with UV-C   light; then the air stream moved through a light-blocking filter into a dark (no light   present) chamber. This stream of treated air was on the experimental side of the   machine. The control side had a stream of air similar in volume and flow to that on   the experimental side. The control side contained no photocatalytic reactors.
- Cultures of E. coli were established on Petri dish plates with agar media. E. coli   colonies on the agar plates were too numerous to count (TNTC) at the beginning of   the test. Eighteen plates with E. coli TNTC were exposed, in groups of three, to the   treated airflow in the dark chamber for 10, 20, 30, 40, 50, and 60 minutes and then   removed to count surviving colonies of E. coli.
