We measured the concentration levels of pollution in traveling cars when our purifier was off and when it was on. This scientific measuring, including analyses by independent certified labs, provides proof of filtration effectiveness that other products in the marketplace, or in patents, do not have. The graph on the right shows Benzene levels in L.A. In our field tests, we were able to bring pollution down from 12 parts per billion to 2.3 parts per billion after just five minutes. Running the purifier for another 90 minutes brought levels down below one part per billion. This is well below the health standard that we target.


All in all, we tested our purifier’s effectiveness against all of the pollutants for which the Environmental Protection Agency (EPA) has set National Ambient Air Quaity Standards (NAAQS), plus Benzene. These are seven of the most harmful pollutants that people are exposed to in their cars. To see a chart summarizing the results for each of the pollutants, click here. We’ve also published a scientific paper, pages 19 through 32, with a complete set of results from our field studies.



The graph above is of particulate matter (PM10) in Bangkok, Thailand. PM10, and especially the smaller segment of that classification, is a threat to human health not only because it includes irritants like dust and pollen. It also includes carcinogens like diesel soot. We went to Bangkok because it’s one of the most polluted cities in the world, and we wanted to put our product to the test. As you can see, it passed with flying colors.


Our Testing Methods

Our testing was done in passenger vehicles with two to four passengers driving in heavy traffic. We ran tests with the windows open and closed, with the ventialtion system on and off, and with the purifier on and off. In the vehicle, we used a DataRAM, eqipped with nozzles for both PM10 and PM2.5 particle sizes. The DataRAM operated on battery and gave concentration level readings every ten seconds. For some tests, we also used an Ozone Spot Checker and a Draeger Gas Analyzer.

In addition to recording information from the DataRAM, our researchers took samples of the air inside the car and sent them to independent certified labs for analysis. Summa canisters were sent to Performance Analytical, Inc. Glass tubes were sent to Assay Technologies Lab.


Testing done by the US Army


In addition to field testing, our product has undergone experimental testing by the U.S. Army Edgewood Chemical Biological Center Laboratory, in the Aberdeen Proving Ground in Maryland. They ran a test to try to determine whether our product was capable of capturing chemical lethal agents.

DMMP was used in the test as a surrogate for Sarin Nerve Gas. At 120 degrees farenheit and 50 percent humidity or less, they pumped contaminated air through our prototype. The air going in to the filter had 5,000 miligrams of DMMP in it per cubic meter. The outflow measurement of DMMP at the start of the test was 0.41 milliagrams per cubic meter. The outflow measurement of DMMP at the end of 22 minutes was 0.60 milliagrams per cubic meter.

The least favorable interpretation of this exploratory test was that the Safe Air Machine (SAM)™ media was able to capture at least 186,873.64 milligrams of the 186,892.27 challenge gas, for an efficiency capture rate of 99.99%. Based on Sarin’s lethal dose for human beings of 0.5 inhaled milligrams, our filter media (approximately 5 pounds of specific types of activated carbon) can adsorb gas capable of killing approximately 374,000 people.
