I talked with Phil Evans at P&R distributing about the Trend Air Shield. He agreed to send me the Pro and Original to try out. I have access to a lab that can do some "basic" testing on these and below are the results. The lab uses an ultrasonic humidifier to create the particulates in the air. A particulate device is connected to a computer and counts the outside versus the inside mask particulate levels via tygon hoses.
For what it's worth here are the results.
The Pro reduces the particulate levels from the 8500+ ppm to less than 100 ppm for a protection factor of 101
The Original reduced the count to about 300 ppm for a protection factor of 21.
This was not a scientific controlled test, I only used the equipment we use to test mask fit for respirators. I'm not exactly certain on the micron of a humidifier versus dust from turning, if water mist is smaller then the Air Shields are even better, if not then you have to judge. Perhaps someone could add that to add more value to the results.
