In September 2011, Dr. Stutzenberger from the University of Clemson let us know his team had conducted an independent study on the leading air purifiers. To our surprise, not only was our Max V-HEPA Air Purifier unit part of that test, but our unit had the top results when compared against the competitive models.

The test was conducted by holding a sterile Nutrient Agar Petri Plate directly in front of the exhaust grid of each unit for a stopwatch-timed 5 minutes. The Petri Plates were closed and taped then incubated for 3 days at 37 degrees Centigrade. See specific results below:

  • Not only did the Max produce the cleanest air, it was the only purifier to produce totally clean air.
