Summary: 1. Ranked #1 by Clemson University 2. Ranked #1 by health expert Dr Bob Martin 3. 100% removal in particle counter testing (1+ microns) and videos (0.3 and 1 microns)
1. The only air purifier to produce completely clean air! The University of Clemson Microbiology Lab conducted tests of 2 leading HEPA air purifiers, the Oransi v-HEPA MAX Air Purifier and the leading electrostatic air purifier (per Consumer Reports) to find the purifier that produced the cleanest air. The Oransi was the only purifier to produce totally clean air. As stated by Dr. Fred Stutzenberger, PhD at the lab, "You can be justifiably proud of your product."
Types of Particles: Mold Pollen Dust Bacteria
Lab Results (Sept 2011) What this Shows: The picture to the left shows the results of the petri dishes that captured the particulates coming out of each air purifier. The other HEPA models results can be seen in A and B and the electrostatic model can be seen in D. The Oransi v-hepa purifier is shown in C.
What this Means: Only the Oransi effectively captured the particles from the air (ie a completely clean petri dish). This is representative cleaning the air of bacteria, mold spores, pollen, and dust.
Test Procedure: 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. The comparison of culturable microbes exhausted by each unit is shown in this image.
2. Dr. Bob Martin who is a leading expert on healthy living with a radio broadcast to over 400 stations calls the Max air purifier "the best air purifier on the market". Listen to the clip.

3.Particle Counter Testing.
What the videos below show: At the start of each video the air purifier is turned on and a particle counter displays two sets of numbers. The number to the left is for particles in the 0.3 to 0.5 microns range (hardest to remove) and the number to the right is a measurement of particles larger than 1 micron (most allergens). The particle counter takes 30 to 40 seconds to calibrate to the cleaner air so the numbers you see at the end of the videos reflect the air that is coming out of each model. Ideally, the numbers should decrease and the closer you get to zero (ie 100% particles removed) the cleaner the air is coming out of the air purifier.
