Princeton Analytical Laboratory Testing:

To whom it may concern:

Princeton Analytical Laboratory is accredited by the American Industrial Hygiene Association for industrial hygiene and air analyses and as the successor to Princeton Testing Laboratory has over 20 years of air testing experience. We have performed air testing for ozone specifically on numerous occasions and have experience with testing the ozone output on various devices. Based on existing data, ozone is an allotrope of oxygen, which is derived or formed naturally from diatomic oxygen by electric discharge. As an oxidizing agent, ozone has been used to purify and deodorize both air and water.

On May 12, 1997, we received from Csonka Cigar Requisites, Inc. (CCRI) an air purification device which CCRI refers to as the Csonka Smoker Cloaker™. We were requested to perform air sampling and analysis for ozone. The air testing was performed on May 21 and 22 using the National Institute of Occupational Safety and Health (NIOSH) analytical method for ozone in air, NIOSH P&CAM 154. This method involves the sampling of air through an impinger containing solution that traps ozone out of the air when the air is drawn through the impinger. This solution is then analyzed spectrophotometrically for ozone. The samples were taken under various conditions, all with the Csonka Smoker Cloaker™ set on "High". Samples were taken at different distances from the device in the open air, from 3 feet from the device to 1 inch away. Ozone levels were not detected in these sampling events most likely due to the ozone's rapid dissipation into the air.

A "worst case scenario" was also sampled, where the sampling device and the Csonka Smoker Cloaker™ were enclosed in a 3.5 cubic foot cubicle. The purpose of this was to try to determine how high the ozone levels might likely be in a very small space. The result for this test was 0.027 mg/m3 which is 0.014 ppm. This result is well below the OSHA standard for ozone of 0.1 ppm. All our tests were conducted with the device on the "High" setting. Because the "Low" setting causes the device to generate ozone for less time, we presume that ozone levels at this setting would be even lower. We conclude that the ozone levels generated by the Csonka Smoker Cloaker™ were well below the levels considered safe by OSHA. As such, it produced safe amounts of ozone.

The Csonka Smoker Cloaker™ is spherical with a flat base and roughly 4" in diameter. The unit tested was supplied with both a 12 volt vehicle cigarette lighter power cord, a 110 volt U.L. listed electrical transformer, rubber feet and velcro adhesive pads. As such, and based on it's size and design, it is both surface and wall mountable, and offers flexibility as to where it may be located and utilized.

Given ozone's ability to reduce the level of airborne contaminants such as smoke, dust, bacteria, pollen, mold spores, pet dander and other pollutants, the Csonka Smoker Cloaker™ may be used for odor control and air purification.
