Ranked #1 by Clemson University

The only air purifier to produce completely clean air based on their testing as described below!

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, pet dander 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.

Best Air Purifier for Large Homes

CNN underscored reviewed air cleaners and rated the EJ120 as best for large living areas.

Simply put, the Oransi EJ120 is the best air purifier we’ve tested

Modern Castle tested the EJ120 air cleaner through a series of real-life tests in a home with a particle counter.

Here is a summary: "The Oransi EJ120 utterly crushed our air purification tests. Within 1 hour it was able to reduce PM2.5 to 0.1, PM10 to 0.0, and reduce AQI to 0. The build quality is impressive, with quality metal / plastic parts, a German EC motor, and a thick filter stack. Its purifies the largest space we’ve tested to date, handling up to 1,250 square feet."

The Tesla of Air Purifiers

We were so honored that Huffington Post featured Oransi as the air purifier solution for air quality issues.

Women's Health Magazine Fresh Air Fave

We were happy to see that Women's Health Magazine recognized the importance of a high CADR to ensure you are getting the cleanest air. They showcased our EJ air purifier and stated "it covers a larger area than most purifiers - so you'll need fewer units if you're aiming to freshen up your entire home."

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".

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.

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 Rating.

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
