2. Familiar With UV? • Our Sun produces UV energy which naturally destroys biological contaminants in the atmosphere. • UV-C Light attacks microorganisms on a molecular level • mutating the DNA of the cell. • UV Has been used for many years in water treatment. • If you are familiar with UV Water Treatment, the principles for • treating moving air are the same. Example of a UV Water Purifier UV Air Purifiers on the Market • You may be familiar with UV Air Purifiers on the market. • They appear to be very similar to the Sanuvox Saber. • They may vary in number of lamps. Some have 1, 2 even 4 • UV Lamps. • Excellent Object Purifiers but NOT very effective Air Purifiers.

3. Purifying an OBJECT VS. Purifying The MOVING AIR There are Two Types of UV Purification: 1. Purifying an OBJECT 2. Purifying moving AIR OBJECT PURIFICATION • A Stick-Light will keep a stationary object clean from biological contaminants. • A Stick-Light will make an effective OBJECT Cleaner but an inefficient Air Purifier. • The Stick-Light Purifier has all the TIME to bask the OBJECT • with UV, guaranteeing nothing will grow on it. • Examples of a Stick-Light Purifier Application: • If installed into a duct, the Stick-Light will keep that portion of the • duct extremely clean from biological contaminants, but do • very little for the air passing by the Lamp(s). • If installed on the coil, the Stick-Light will keep the coil • clean from biological contaminants but do very little for the • air passing by the Lamp(s). • NOTE: Direct UV light is destructive to plastics (drainpan, wiring, motor windings, etc.).

4. Purifying an OBJECT VS. The MOVING AIR AIR PURIFICATION • Purifying MOVING AIR is completely different than purifying a Stationary Object. • A Stick-Light Purifier is an effective Object Purifier because the object is not moving therefore the • need to deliver such high amounts of UV within a fraction of a thousandths of a second is no longer • needed. The UV energy will shine on the object indefinitely. To Purify MOVING AIR, there is only a fraction of a thousandths of a second to deliver the UV dosage needed to destroy the contaminant in the moving air-stream.

5. The Two Inch Rule • Some manufacturers promote that their one and two lamp Stick-Light purifiers • will treat the entire volume of air passing through the duct at one time. • Unfortunately, that could not be further from the truth. According • to the Lamp Manufacturers, efficiencies DROP very quickly the • further from the Lamp surface you move. • At just 2” from the surface of the glass, the UV efficiency has • already dropped 80% and the decline is exponential. • This is true for all types of UV Lamps, from cold cathode to hot • cathode, soft glass to quartz glass. This is an example of a competitors suggested treatment area. • Manufacturers who promote that their one and two Lamp Stick-Light Purifiers will purify the entire • duct are in reality only TREATING A VERY NARROW BAND OF AIR that travels by the Lamp. • As will be discussed, even that narrow band of air is not being • treated adequately because the air is moving much too fast in • the duct to receive the proper UV dosage. **The 2” Rule is the reason why the “J” Lamp is mounted inside the Aluminum Reflector Tube. The purifier will maximize the UV Energy which would otherwise be lost in the duct-work. sanuvox technologies inc.

6. The Two Inch Rule The Two Inch Rule These Stick-Lights are perpendicular in the air-stream The contaminants “zip” right by the Lamp The air is traveling just too quickly to be treated. The moving air only spends a FRACTION of a thousandth of a second in contact with the Lamp! sanuvox technologies inc.

7. The Two Inch Rule There is a big difference between the UV that can be “seen” and effective UV. Although UV light can shine for a great distance, that light has virtually NO Germicidal effect on moving air. Only the UV within a couple of inches of the Lamp is effective in treating moving air, the rest is lost within the duct. The two inch rule only applies to air purification (treating moving air). When treating moving air, there is only a fraction of time to treat the contaminant in the air-stream. That’s why an air purifier needs an intense amount of UV energy. In contrast, the two inch rule does not apply to object purification (purifying a stationary object). The object is not moving therefore the need to deliver such high amounts of UV within a fraction of a second is no longer needed. The UV energy will shine on the object indefinitely. Light from our Sun can be seen here on Earth, but not nearly as powerful as it is in space. sanuvox technologies inc.

8. Efficiencies & Testing • Many manufacturers are claiming a destruction of 80% or more on their one and two Lamp • Stick-Light purifiers against their TEST BACTERIA. • Many manufacturers are using Serratia marcescens as the test bacteria; Serratia marcescens is • a weak bacteria to test against (3 400 MICROWATTS PER/CM² OF GERMICIDAL UV FOR • DESTRUCTION ). • In contrast, Sanuvox tests are done in real world conditions and through clinical studies. • Sanuvox results have shown mold levels dropped 100%, Mycobacterium tuberculosis • (10 000 MICROWATTS PER/CM² OF GERMICIDAL UV FOR DESTRUCTION ) dropped • more than 90% and VOC's (Volatile Organic Compounds) dropped 50%. • According to the information supplied by other manufacturers, the Sanuvox R3500X destroys • a higher % of contaminants that require at least 300% more UV dosage than their one and • two lamp Stick-Light units. sanuvox technologies inc.

9. Efficiencies & Testing • The Sanuvox R1500X & R3500X In-Duct UV Air Purifiers will purify a portion of the air • moving within the duct at any given time. • The air within our homes continually circulates through the ventilation system every minute of • every hour of every day. • Sanuvox R1500X & R3500X rely on that re-circulation to bring the overall level of • contaminants down. • After an hour or two of having the purifier installed, the home will have circulated the air • through the purifier enough times as to bring the home’s overall contamination down • drastically. • The In-Duct Purifier will destroy the • contaminants quicker than they can • be introduced into the environment. • The R3500X treats the air with10,959 • microwatts per/cm² of UV intensity • inside the Aluminum Reflector Tube • over a distance of 12”. sanuvox technologies inc.

10. Relationship between UV-V & Residual Ozone Relationship between UV-V & Residual Ozone • Sanuvox Purifiers do not produce ozone as their primary function. The UV-V section of the • Dual Zone Lamp (approx. 10% of the Lamp glass) may produce a small amount of residual • ozone. • The Residential Purifiers that use a Dual Zone Lamp have in tests produced 0.003 ppm. of • residual ozone. So minute, that some tests show zero amount of residual ozone in the • environment. • Sanuvox Residential Purifiers produce less residual ozone than a photocopier or an electronic • air cleaner. The amount of residual ozone that can be produced by a Sanuvox Residential • Purifier (0.003 ppm.) is a fraction of the ASHRAE ( 0.05 ppm.) and OSHA ( 0.10 ppm.) • standards for safe levels of ozone. • Sanuvox designed the UV-V portion of the lamp to • “fire” first. While contained in the Aluminum Tube, • the UV-C (approx. 90% of the Lamp glass) Germicidal • Energy acts as a catalyst to speed up the process to • keep any residual ozone to extremely low levels. sanuvox technologies inc.

11. Relationship between UV-V & Residual Ozone Relationship between UV-V & Residual Ozone • By incorporating UV-V into Sanuvox Purifiers, studies have shown a significant decrease in • VOC's while producing virtually no residual ozone in the environment. • Sanuvox Purifiers not only destroy biological contaminants, but are also able to destroy • toxins, chemical contaminants such as diesel fumes, cigarette smoke, formaldehyde, pet and • cooking odors. It is impossible for UVC Germicidal only Stick-Lights to treat any of these • chemical contaminants or odors. • UV-V does NOT mask odors or • contaminants; UV-V • molecularly changes • the molecule(s). **Sanuvox Purifiers are available as both UVC & UVV, or UVC only. R1500X & R3500X UVC / UVV, Germicidal / Oxidation R1500G & R3500G UVC, Germicidal only sanuvox technologies inc.

12. Installation • The installation of an R1500X or R3500X requires no more than 10-30 minutes • by an HVAC contractor. • The purifiers can be installed on either the return or supply side of the plenum. • We recommend installing it on the return side for the added benefit of keeping • the filter and coil cleaner then if the purifier was installed on the supply side. • The R1500X is hardwired to the fan relay, and the R3500X is simply plugged • in, the airflow sensor automatically turns the purifier on and off. If there is not enough room for the control box on the outside of the duct, both purifiers can be remotely installed with the optional Remote Kit. The Remote Kit allows the Reflector Tube and Lamp to be installed in the duct, and the control box remotely installed in another location. • Direct UV light is destructive to plastics (drainpan, wiring, motor • windings, etc.), the Reflector Tube can easily be positioned so no • UV will see any plastic. A Stick-Light purifier has no measure to • control what the UV sees. sanuvox technologies inc.

13. Mercury Vapor 19mm. Quartz “J” Lamp • While Stick-Light purifiers use multiple lamps in order try to increase intensities. Sanuvox uses one • Lamp which is bent in on itself into the shape of a “J”. • This has the effect of having the two legs of the lamp treat the air, which is the equivalent of • having two straight lamps. • Unlike most Stick-Light purifiers, Sanuvox Lamps are Quartz glass not Soft glass. Quartz glass • produces higher levels of UV Intensity and have a longer operating life than Soft Glass. • Sanuvox Lamps are 19 mm in diameter, not 15 mm like other UV Lamps. The Getter • The Getter is incorporated into the Lamp. • More environmentally friendly. Uses less than ½ the amount of mercury used in other Lamps. • Designed to absorb pollutants inside the Lamp which are created as the Lamp burns. • Better maintains UV intensity and Lamp Life Anode • Designed to easily ignite the mercury vapor for less strain on the filaments as the Lamp • starts. sanuvox technologies inc.

14. 3 Year Warranty • Stick-Light purifiers (including the Sanuvox Saber) have a maximum lamp life of 8700 • operating hours (1 year). Stick-Light purifiers must have each Lamp wiped clean every 2-3 months • to remove the bio-aerosols in the air-stream that adhere to the Lamp and block the UV rays. • The R1500X and R3500X have a 3-year warranty, which includes • the UV “J” Lamp and all replacement Lamps. • As a result of the proprietary design, the Aluminum Reflecting Tube • redirects UV to “burn off” any bio-aerosols that adhere to the UV • Lamp. • The R1500X and R3500X are self-cleaning; the only maintenance • required is a one Lamp change every 3 years (Sanuvox takes into • consideration the unit will operate 24 hours a day, 7 days a week, • 365 days a year). UV Lamps age, and as they age, they lose their effectiveness. The Sanuvox Saber is the same as any other Stick-Light Purifier. We can ONLY offer a 1-year warranty on the Saber Lamp because the purifier is a) mounted perpendicular to the air-stream, b) does not use any measure to slow the air down as it passes over the lamp, and c) does not use any reflectivity to increase UV intensity. sanuvox technologies inc.

16. sanuvox – 101 A short lesson in UV Any bacteria can be destroyed with UVC light; the question is how to do it? sanuvox technologies inc.

17. Two Factors in achieving a high bacteria kill are : • The INTENSITY of the UV source and • The greater the INTENSITY the greater the kill. • The length of TIME the bacteria is exposed to the UV light • The more TIME the bacteria is suspended in front of the UV light, the higher the UV dosage it receives, • the greater the kill. sanuvox technologies inc.

18. Intensity • The R1500X and R3500X achieves a high intensity through the use of Reflection. • The same way a flashlight or car's headlight uses a reflector to intensify and direct light. The • Sanuvox UV Air purifiers use an Aluminum Reflector Tube to intensify the UV Energy. = How powerful would a flashlight be without a reflector? sanuvox technologies inc.

19. Dwell Time How does Sanuvox slow the bacteria down so it can receive the UV dosage needed to kill it? • The Turbulator slows, twists and mixes the air around the Lamp, dramatically increasing the time • the contaminants are suspended in front of the lamp. • That's what Sanuvox does. Slow down the air so the contaminant can be “burned” by the UV • Energy. The more time in front of the lamp, the higher the UV dosage the contaminant receives, • and the higher the kill. Very similar to putting your hand over a candle. If you were to quickly move your hand through the flame, you would barely feel the heat. Should you move your hand slowly through the flame, you would surely be burned. The more time in front of the UV Energy, the higher the kill. sanuvox technologies inc.

20. Dwell Time • Finally, to increase the dwell time (the time the contaminant is in contact with the UV Energy), the • purifier is mounted parallel to the air-stream not perpendicular, maximizing the time the contaminant • is in contact with the UV lamp. • If properly delivered, UV Irradiation can be a very efficient method for air purification. The use of the • Turbulator, Aluminum Reflector Tube, • “J” Lamp and placing the unit parallel to • the air-stream are the “tools” needed to • maximize the UV Energy. The air spends 2400% MORE TIME in Contact with the UV Energy than does a Stick-Light Purifier. Parallel = Increased Dwell Time Perpendicular = a fraction of Dwell Time sanuvox technologies inc.

21. Dwell Time The following are competitor’s Sample Illustrations that show the units treating a large portion of the duct. In reality, the stick-lights are treating the duct not the contaminants in the moving air. The Stick-Lights, are inefficient in destroying moving contaminants in the air-stream, but will keep that portion of the duct surface clean from biological contaminants. Because the duct is stationary, UV is shining on it indefinitely. The duct does not need the same intensity to keep it clean from contaminants as moving air needs. A competitor’s standard 90° Installation Are they trying to make their Lamp parallel to the air stream? And their 45° Angled Bracket sanuvox technologies inc.
