What's In Your Air?
Public interest and concern regarding indoor air quality has grown considerably over the last few years. As energy efficiency has become more important and more synthetic materials are used In building and furnishing our homes and workplaces, the problems associated with indoor air pollution have Increased, In fact, Indoor air pollution is now considered by the EPA and Congress to be America's #1 environmental health problem. Indoor air is polluted by toxins from a host of sources. Carpeting, paneling, vinyls, particle boards, plastics, insulation, cleaning chemicals, pesticides, and even bedding and clothing all off-gas potentially toxic chemicals. The control of these pollutants is extremely important because of the long term detrimental effect they can have on human health. Common symptoms resulting from poor indoor air quality include: headaches, fatigue, eye irritations, asthma attacks, breathing problems, dizziness, memory loss, depression, skin irritations, sinus infections, colds, flu and viruses. Even with no noticeable symptoms, however, exposure to even low levels of contaminants can increase an individuals sensitivity to the substance and potentially lead to long term health problems.
We are continually exposed to a growing number of health threatening pollutants that can be categorized into three groups: biological contaminants, toxic gases, and particulates. To deal with these hazards, Environmental Treatment Services units combine powerful purification methods. As air enters the Environmental Treatment Services unit, it is channeled Into the air purification chamber. In the chamber, the air is exposed to intense levels of germicidal ultraviolet light for destruction of organics. These powerful wavelengths also energize the gaseous contents of the air producing a purifying plasma that destroys bacteria, viruses, fungi, VOCs, and other organics as well as neutralize unpleasant odors. Also in the chamber particulates such as dust and smoke are bombarded by photoelectrons to remove them from the air. The ultrapurified air is then blown back into the room carrying with it the purifying plasma which then circulates throughout a dwelling destroying harmful pollutants.
These units also feature advanced engineered electronics. An exclusively designed power source utilizing constant wattage circuitry ensures optimum electronic efficiency and consistent performance. Plus, with the supplied UL listed AC/DC adapter, the units run on 12VDC providing the utmost in safety. There is little maintenance required and they are specifically designed for ease of operation and low cost of ownership. UV Light Examples: Click Here
1. Purifying Hydroxyl Radicals (OH)
Environmental Treatment Services air purifiers use a patent-pending process to create hydroxyl radicals (OH) which are much more powerful at purifying the air than even ozone. Hydroxyl radicals are 33% more powerful as an oxidant than ozone, and 2.5 times more powerful than chlorine, making them that much more effective at destroying fungi (such as mold), bacteria, viruses, germs, chemical fumes and vapors, etc.
According to a recent New York Times article (May, 2001), hydroxyl radicals are thought by atmospheric chemistry scientists to purge more than half the sulfur dioxide added to the air by smokestacks, volcanoes and other sources.
Also, atmospheric experts from a Study being conducted over the Indian Ocean concerning hydroxyl radical levels advise us that without hydroxyl radicals, air pollution can persist for much longer, exacerbating its effects, since it is needed to clean remove toxins from the air.

How Our Air Cleaners Produce Hydroxyl Radicals
Environmental Treatment Services air purifiers produce just enough ozone to enable the production of hydroxyl radicals. As the ozone is produced, it Is exposed to the UV light, which breaks the 03 into 02 and 01 ("oxygen singlet" molecules). The 01 molecules are highly reactive, and will combine with hydrogen atoms in the air to make OH (hydroxyl radicals), which are an extremely powerful air purifying agent.
The Environmental Treatment Services air purifiers are able to produce much higher quantities of hydroxyl radicals (which have no harmful side effects) than any other UV air purifier. This Is the result of being able to produce a much more consistent UV wavelength, which results in continuous production of hydroxyl radicals.
They utilize an exclusive 12-volt power supply which results in unprecedented consistency and stability at producing short UV wavelengths. All other UV air purifiers use methods that result In fluctuation of the UV wavelength, so the hydroxyl radicals are not produced continuously. This 12-volt technology allows the bulb to take in the power smoothly, while all other methods cause the bulb to take the power in cyclical surges.
Effectiveness and Safety of Ozone:
Ozone is highly reactive, and oxidizes pollutants it encounters, rendering them harmless, while also removing odors. It (O3) loses one of its oxygen molecules in this oxidation process, causing it to revert back to oxygen, leaving behind pure, fresh air. Ozone can be effective against chemical sources, bacteria, mold, odors, etc. Once a pollutant is oxidized by ozone, It is no longer toxic, allergenic, or odor causing. As a result, even if an oxidized contaminate remains in the air and is inhaled, it has no effect. Plus, ozonated microorganisms (such as mold spores or bacteria) are no longer able to reproduce, which causes their numbers to quickly diminish.
How Environmental Treatment Services Air Cleaners Produce Ozone Environmental Treatment Services air purifiers produce only enough ozone to enable the production of large amounts of hydroxyl radicals. As a result, safe ozone levels are guaranteed. Environmental Treatment Services air cleaners produce ozone with a patent-pending ultraviolet (UV) light lamp. As a result, they do not create oxides of nitrogen as a byproduct like ozone generators using plates can. Nitrogen oxide can serve as a minor irritant, and can create a "metallic" or "bleach-like" smell.
Environmental Treatment Services air purifiers ozone air that circulates into its chamber, then also emit the ozone throughout the area in which it is specified to cover. Ozone distribution is also aided by the natural air currents In your home or workplace . Environmental Treatment Services air cleaners are designed to keep safe ozone levels within.04 parts per million when operated according to instructions, which Is within the FDA and OSHA standards of .05 parts per million.
Most ozone air purifiers use the corona discharge method for creating ozone, which is not as reliable and consistent As a result, there is more of a likelihood that such a unit will need repair work, and that it will produce excessive ozone levels, unlike our air cleaning system.
How Negative Ions Work
Negative ions purify the air by magnetically attracting to pollutants until these newly-formed larger particles become too heavy to remain In the air you breathe. Environmental Treatment Services air cleaners continually produce negative ions and ozone, so even if one of these fallen particles is kicked up into the air, It is quickly removed again. These fallen particles are typically collected by your normal cleaning activities. The most important thing though, is that they are taken out of the air, preventing you from Inhaling them into your lungs, which is how they cause problems.
How Environmental Treatment Services Air Purifiers Produce Negative Ions: Environmental Treatment Services air cleaners use photoionization (patentpending) to produce negative ions. The UV bulb inside the unit produces photoelectrons, which reacts with conductivity of the metal shield inside the chamber to create negative ions. Photoionization creates 4,000 to 7,000 negative ions per cubic centimeter, which is enough to somewhat reduce floating particulate such as dust mites, smoke, chemicals, etc.
By contrast, most indoor environments offer between 100 to 250 negative ions per cubic centimeter.
Most ozone-negative ion combination air purifiers use the corona discharge method for creating negative ions, which results in a negative ion concentration of about 1,000 ions per cubic cm.
The Environmental Treatment Services photoionization process also prevents "black wall" effect. This Is a condition where high densities of negative ions, although very healthy for you, can blacken walls and furnishings by magnetically attaching to them.
Ultraviolet light has been used for years by the medical field to sanitize rooms and equipment, and is recommended by Centers for Disease
Control for its ability to destroy germs and other biological pollutants. Now this technology is available for home air purification units.
Ultraviolet light from the sun destroys viruses, bacteria, fungi, and other pollutants, including mold spores. LifeTech UV lamps offer a much higher concentration of ultraviolet light than even the sun. UV light damages the DNA structure of the microorganism, causing its destruction. Once the UV light sterilizes the pollutant, it is no longer able to reproduce (which Is how harmful micro-ogranism levels are sustained and Increased). It then becomes inactivated, or microbiologically dead, rendering it harmless. Since the ultraviolet light is only directed inside the unit, there are no potential harmful side effects.
The UV lamps treat the air that enters the system's chamber through the indoor environment's natural air currents, and also with its fan. Plus, the unit uses a unique convection process to draw additional air through the unit, above and beyond what is achieved by way of natural air currents and the fan. The purified air is then blown back out.
The geometrically-designed metallic shield inside directs the air closer to the bulb, while causing the air to spiral around the bulb. As a result, bacteria and chemicals are forced to stay close enough to the bulb for sufficient amount of time to be destroyed.
Environmental Treatment Services UV lamps are powered by 12 volt direct current (internally generated), which provides constant wattage without fluctuation. Fluctuating power has traditionally been a problem spot as far as UV light generation is concerned, but has finally been cured with Environmental Treatment Services new technology.
