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.
The military has also tested our prototype. Read the specifics about this test here.
