EJ120 Air Purifier

The Industry-Standard

Merv 17 HEPA (99.97%+) performance. Proprietary carbon and potassium permanganate for advanced gas control. And it's super quiet. Silent on the first two fan speeds and on high much quieter than any other high-end air purifier.

Best Reliability and Quality

Air purifier housing, filter media and electronics all made in USA. Only mechanical filtration. No ionizer or anything else that could potentially create ozone.

Efficient

Latest German engineered motor is quieter and uses up to 90% less energy saving since it draws a max of 83 watts and delivers a high 384 pollen CADR air flow.

Note: to increase odor removing effectiveness we use a softer carbon. In shipping if the box has excessive vibrations it's possible for there to be carbon dust on the front cover. To clean, simply wipe with a lightly damp cloth. The carbon filter can be lightly vacuumed, especially if it collects a lot of dust or pet hair.

Room Size

Up to 1,500 sq ft with 2 air changes per hour. Learn more about air purifier room size and see AHAM Verifide results.

Perfect for large home living areas, offices, healthcare facilities, nursing homes, mold and asbestos abatement and any other small to large square footage space that requires portable air cleaning.

The EJ is super quiet - in fact the quietest air purifier on the market for the given air flow. And on the lowest fan speeds we could not detect any sound in the sound chamber testing.

Effective For

EJ Story

We searched the world to build the ultimate air purifiers. In Germany we found the largest factory of high performance, super efficient motors. Best yet, they are super quiet. So, you get high performance and reliability with low energy usage.

EJ is the newer, smaller version of the ERIK650A. EJ stands for Erik Junior. While it is smaller, the EJ120 has a strong CADR of 384 for pollen and is our quietest high performance air purifier. And it does this with only drawing 83 watts of power.

HEPA filters were invented in America and through engineering and rigorous testing in America we have improved the HEPA filters.

Carbon is widely used for gas removal however does not work well in humid environments or for formaldehyde so we developed a proprietary treatment to solve these problems.

To ensure the highest quality and safety we make our air purifiers in America.

We are focused on improving the most important part of your life - protecting the health for you and your family.

Energy Savings

Average Energy Savings: $168/year

How do you build the ultimate air-cleaning machine? It's simple; you combine the best filters with the best fan and make it in the USA. As allergy and asthma sufferers ourselves, we built the air purifier that we would want to use. Turn your room into a cleanroom!

The difference between this purifier and the Erik650A is that the Erik650A has more HEPA filter media and about 25% more air flow. The HEPA filter in the ERIK650A is a MERV18 and the EJ is a MERV17. The pre-filter in the ERIK650 is MERV15 while the EJ uses the carbon filter as the pre-filter. The EJ is much quieter.

Best filters

The EJ air purifier has two filters – a 1” deep GAC impregnated activated carbon/potassium permanganate bed pre-filter and a 3” deep main HEPA filter. Effective for gases for smoke and gas leaks (methane gas, sulfur gases, and many others).

The main filter is the same industrial filter that is trusted by hospitals and removes much more than any true HEPA filter.

Filter Sequence

If you remove the filters, the white HEPA filter should be inserted first with the black seal facing inwards (in the picture below we show the seal so you can see it although be sure to place the seal facing in). This will ensure it makes a tight seal with the metal frame of the air purifier. The carbon filter is installed next and also acts as a pre-filter. So, when you open the front cover the first filter you should see is the carbon filter.

EJ Filters
EJ HEPA filter
EJ carbon filter
  • Pre-filter is 1" deep carbon filter with 3.5 pounds of our proprietary gas filter media that is effective for a wide range of gases and odors.
  • HEPA main filter (99.97%+ at 0.3 microns) is 3" deep


Having more filter media means the main filter will last longer (1+ years) and it creates less air resistance. By not having to work as hard the motor can spin at a slower, quieter rate.

These are the same filters used in Hospital Operating Rooms, the Nuclear Industry, Containment units, Laboratories, and Pharmaceuticals.

Best Motor/Fan

EJ (like our Erik series) has the best, latest German engineered EC motor and fan so it provides higher air flow while being quieter and using much less power. The EC motor is a much-improved technology over the traditional AC motor that nearly every other air purifier uses.

AC motors use technology that was developed in the 1800’s and use more energy, can have an annoying hum, and are not as reliable. They are common because they are very inexpensive to produce.

EC Motor Advantages

EC (Electrically Commutated) motors use electronics to convert the AC voltage to DC to run the motor. EC is the latest technology innovation whereas AC motors use technology from nearly 200 years ago. With an AC motor from China, chances are that the copper was wound by hand and the ball bearings are of low quality making it unreliable.

  • EC motors are DC so they are more efficient and use up to 90% less power and in the long term can provide significant cost savings.
  • Runs cooler so greater reliability.
  • More compact.
  • Has a proven track record in the telecomm and computer industry.
  • No motor hum that you get with an AC motor
Why does the motor/fan start and stop more slowly than an AC motor? EC motors have a soft start programmed into the motor to limit the start-up current the motor draws (there are electronics built into the motor). The ramp down after power is removed is only a function of the inertia of the fan and the friction of the bearing system. A high quality bearing system will take longer to slow down and stop since the friction is minimized (alignment is better, lubricant is better, etc.).
Motor Humming 101

The humming noise comes from the fact that it is an AC motor and all the magnetics are changing intensity at the line frequency. When rotating, these forces are aligned so as to rotate the rotor. When the motor is not rotating or rotating at a speed lower than synchronous speed, they tend to make things vibrate back and forth and that makes the humming sound. If you have an AC motor that starts slowly, the humming starts louder and decreases as the rotor and field come into sync.

Tested in World Class Labs

To ensure we can deliver the best air purifier we thoroughly test in the top labs.

EJ Air Purifier is excellent! September 28, 2017
Reviewer: CCH from Northern California  
I live in rural northern California and have been thinking of getting an air purifier for the past several years due to the increasing number of wildfires. Some fires burn for weeks and create a smoky haze for hundreds of miles. After researching numerous less expensive alternatives, I finally purchased the Oransi EJ three weeks ago. Being a skeptic, I also purchased a Dylos Air Quality monitor to actually quantify any improvement.  Before turning on the EJ, the ambient PM2.5 as measured by the Dylos was 3500-3750 (very poor).  Within 15 minutes of turning on the EJ, the measurement fell to 25 (excellent). It was amazing to watch the number drop so quickly. This was in a ~180 sf bedroom with the EJ running on high (5).  I can maintain the "excellent" range running it at the slower speeds (2-3) as long as I keep the door and windows at least partly closed.  I am extremely happy with the air purifier and consider it well worth the investment. Thank you for a great product.

We can breath again ... September 21, 2017
Reviewer: Mike Guthery from Montana  
The gal on the order desk was excellent at getting me one of their EJ Air Purifiers as they were in short demand because of wild fires going on up here in the Northwest. Even to the point where UPS lost the 1st shipment they sent, and she arranged to get me another unit and Oransi shipped that one  "next day air" to me. That was important because we were caught between two forest fires with smoke so thick you literally couldn't breath outside.
As for the unit, it is costly. More than I originally wanted to spend, but what cost do you put on the ability to breath ? The unit kept the air quality inside our cabin breathable, and that's all we hoped it would do...we plan to use the unit again this winter when our cabin will be shut up tight because of the cold...
