The only air purifier to produce completely clean air!

The Clemson University Microbiology Lab conducted air purifier tests of 4 leading air purifiers. Three popular HEPA air purifiers and the leading electronic air purifier (per Consumer Reports).

The goal was 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."

What this Shows

The picture to the left shows the results. Petri dishes captured the particulates coming out of each air purifier. The cleaner the petri dish the better the filter. The other air purifier results are in A, B, and D. The Oransi air purifier is C.

What this Means

Only the Oransi removed all particles (ie a completely clean petri dish). This is representative of cleaning the air of bacteria, mold spores, pollen, and dust.

Test Procedure

The test was conducted by holding a sterile Petri dish in front of the exhaust of each air purifier. This was done 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 microbes exhausted by each unit is shown in this image.

Ranked #1 by health expert Dr Bob Martin

Dr. Bob Martin is a leading expert on healthy living. His radio program is broadcast to over 400 stations. He calls the Max air purifier "the best air purifier you are going to find". Listen to the clip.

Particle Counter Testing

What the air purifier test 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. These are the smallest and hardest to remove. 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. 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 with this test. The closer you get to zero (ie 100% particles removed) the cleaner the air is coming out of the air purifier.

Independent test lab results for the EJ120 measured at 0.3 microns.  The results are above the standard for a true HEPA filter.

Energy Star & High CADR Rating

AHAM sets the industry standard for air purifier testing.

The Erik air purifier is the only made in USA air purifier to be Energy Star rated with a high CADR.

CADR stands for Clean Air Delivery Rate. This reflects the filtered air flow.

Here are the certified CADR numbers for the EJ120:

  • Tobacco Smoke CADR: 323
  • Dust CADR: 332
  • Pollen CADR: 360

AHAM Verifide CADR

The EJ120, has a coconut shell based activated carbon filter that has been specially treated so it can adsorb a wide range of gases, VOC’s and chemicals. See this page to see the test results
