1 Ozone Air Treatment Applications

2 Presentation Overview  Ozone & Air Safety  Occupied Spaces versus Unoccupied spaces  Commercial vs Residential  Whole-Home Integrated-Fully (WHIF)  Point-of-Use (POU) or (PU) for short  Preventative versus Remedial  References

3  Ozone can be used in occupied spaces safely and effectively with the correct dose being applied. Point-of-Use systems make proper dosing difficult so extreme care must be taken to prevent unhealthful levels of ozone in close proximity to living things.  There is a growing regulatory consensus on standards concerning safe levels of ozone.  The latest legislation, California State Assembly Bill AB 2276, sets 0.05 ppm as a safe ozone level for indoor areas occupied for extended periods of time. These standards, which go into effect December 2008 are the toughest globally. Ozone & Air Safety

14 Ozone is often labeled Smog because most hydrocarbons are difficult to measure accurately. Since, ozone is accurately measurable, it has long been used as the key indicator of the presence and severity of smog. When the other components of smog rise, so does the level of ozone.

16 (occupied by people, plants or animals)  Occupied Spaces (occupied by people, plants or animals)  Residential  Commercial  Hospitals, Extended Care Facilities and Prisons  Hotels and cruise ships  Work-out facilities and locker rooms  Bars and Restaurants  Medical Applications & Temporarily Unoccupied Spaces  Unoccupied & Temporarily Unoccupied Spaces  Food storage  Clothing storage  Smoke damage  New construction (VOC’s)  Existing mold remediation  Operating and clean rooms Occupied vs Unoccupied Ozone Air Systems

17 Occupied vs Unoccupied Air Systems  Occupied / Preventative  UV Sterilization (254mw) UV light has the ability to effect the function of living cells by alter ing the structure of the cells nuclear material, or DNA. The end result is that the organism can not reproduce.  UV Ozonation (185mw) Ozone physically destroys the cell membrane through the oxidation process. As an added benefit, ozone oxidation also alters the molecular chain of non- organic materials as well. (VOC’s)  Unoccupied / Remedial  CD Ozonation (Corona Discharge) CD ozone has the same properties as UV ozone, but can generate much higher concentrations. It requires acceptable levels of NOx by providing dry air feed gas or a CD design that makes low levels of Nox

18 Occupied Spaces  Centralized Systems Whole-House Integrated Fully (WHIF) are mounted at a central point of air distribution within the HVAC duct work.  Residential forced-air heating and cooling  Commercial and industrial air moving and ventilation  Clean room and hospital ventilation  Sewer off-gas ventilation and deodorization  Point-of-Use (PU) are packaged as self- contained table-top or floor units that service one room at a time. Models vary, some having fans,others having filtration and still others both..  Bathrooms  Hotel rooms  Fire damage  Mold remediation

20  Ion: This method uses electrostatic attraction of oppositely charged ions and a collector to attract dust particles  HEPA: Is an extremely effective filtration process HEPA stands for High Effenciay Particulate Air Filter. HEPA typically filters down to 0.3 micron  PCO: PhotoCatalytic Oxidation is UV activation of Titanium Dioxide TiO 2. This is primarily a surface disinfection process.

21 Whole-Home Selling Points

22 Pros:  Whole-home treatment - Tied to central HVAC system  Invisible operation - inside the ductwork  Silent - no moving parts  Unobstructed air flow through the duct system  Automatic On/Off operation linked to HVAC System Operation  Unlike filters does NOT require more powerful fans to maintain air flow:  NO increased energy use  NO restriction of air circulation through the homeCons:  Dealer installed  Dealer serviced Whole-Home Integrated Systems

23 Point-of-Use Systems Point-of-Use (PU) Systems  Reduce some airborne irritants and allergens  Inexpensive  Small portable units  Easy to operate,  Good single point treatment: laundry room, pet room Cons:  Often produce ozone in immediate proximity of people  Treats just one room at a time  Harmful to asthmatics and those with lung & heart disease  Current products soon to be outlawed by California AB 2276

24 Unoccupied Spaces - Fumigation & Remediation Remedial Applications Flood damage Flood damage Smoke damage Smoke damage New construction (VOC’s) New construction (VOC’s) Existing mold remediation Existing mold remediation Major odor problems Major odor problems Hog farms Mushroom farms Poultry farms Fish processing plants Fumigation Applications Cold storage Cold storage Pest control with Grains Pest control with Grains Insurance projects Insurance projects Fresh Picked FlowersFresh Picked Flowers

25 Self Contained Mobil Ozone Fumigation Trailer Unoccupied Spaces Remedial Applications  Mold  Mildew  VOCs  Smoke Ozone is safe and effective in the treating buildings contaminated with mold and spores while cleared of humans, pets, plants that would be harmed by high concentrations of ozone. Ozone concentrations are typically raised to between 10-20 ppm and maintained from 4 to 24 hours, depending on the severity of the problem, prior exhausting the ozone from the building. In-home fumigatio n

26 Unoccupied Spaces Cold Storage Applications  Citrus  Stone Fruit  Vegetables Controlled atmosphere warehouses store fruit and vegetables in large nitrogen enriched, negative pressured rooms at < 40º F. Ozone can affectively reduce the airborne spoilage spores such as mold, mildew and help reduce surface microorganisms. The proper installation requires:  Caution must be exercised with ozone dosage to avoid physicochemical changes to the commodity.  Worker safety is paramount. A reliable, high grade ozone monitor must be used to determine safe levels prior to entry as well a personal respiratory devices available.

27 Recommendations / Comments  Ozone is proven to be effective in many air applications and can be used safely and effectively.  Evaluate you needs: Remedial or Preventative, Point-of-Use or Whole Home  Buy from a reputable company  Be safe: don’t expose people to unhealthful amounts of ozone  Check for 3rd party testing: independent lab results, UL, EPA  Ozone will not be effective on mold or mildew located under carpet or behind most obstacles.

28 References  Dr. Charles Sopher, a specialist in the study of gaseous ozone applications   Medallion Healthy Homes of Canada, Inc  Ms. Beth Hamil, contributing industry professional  United States EPA  AeroQual, Eco Sensor and InUsa all make ozone in air analyzers. Prices range from $500 to $5,000. Eco Badge makes a personal ozone monitors.
