EJ HEPA filter replacements are $95.00 while carbon filter replacements are $79.00.
However, with their lifespan and the efficiency of EJ’s German EC motor, you’ll save an average of $168 per year in energy costs.
Some competitors haven't shared their certified CADR test results (the standard for measuring performance) from AHAM (Association Home Appliance Manufacturers) on their websites. With Oransi, you get full visibility on EJ’s performance and we’re confident that it’s at the top of its class. That’s why EJ was declared the CNN Best Air Purifier for Large Homes 2019 and Women's Health Editor's Choice 2019.
Due to our high-efficiency German EC motor and premium quality filters, you can save an average of $168 per year in energy costs versus using the high-end purifiers from competitors.
Yes, EJ can run 24 hours per day, 7 days a week. That will provide the cleanest air.
Over the life of the EJ, it is cheaper than competitor models at similar price points. This is because when you factor in energy savings, filter lifespans, and warranties, competitor models end up costing more (even if they’re listed at $50 or $100 cheaper right now).
Some find this out the hard way after their competitor model kicks the bucket in under 5 years.
EJ is built to last and should last you up to 10 years. Should something go wrong due to manufacturer defect, EJ is covered by our 10 year warranty. Try finding a better warranty with other purifiers!
EJ will arrive ready to use in under a minute. Just remove the plastic wrap from the carbon filter and plug in the power cord. It’s that simple.
Using an air purifier shouldn’t be rocket science. That’s why EJ features simple controls with an electronic 5 speed button to dial in the exact air flow.

EJ is a powerhouse air purifier. No matter your climate, it’ll get the job done.
Humidity has no effect on EJ’s performance. Live in Florida or near the Great Lakes? You won’t need to worry about EJ’s airflow.
EJ is made in the United States with a premium quality German EJ motor.
Why does buying American goods matter? The National Retail Federations says that if each of us spent just $64 on American made goods, the result would be 200,000 new jobs.
The total weight of the EJ unit + filters is 27 lbs. In other words, it’s about as heavy as a small dog, like a wiener dog.
The total shipping weight is 29 lbs.
EJ measures in at 17" x 19" x 10" (W x H x D)
Yes. Bacteria grow to about 1 to 5 microns in length. The good news is that EJ is 99.99% effective against particles that are as small as 0.3 microns, 99.6% effective against as small as 0.1 micron, and 97.34% effective against particles as small as 0.03 microns.

Oransi was started because of our founder’s struggle to find an air purifier for his son who had asthma. We get the struggles you are going through. We make our air purifiers with the best HEPA filters available. This way they filter out the smallest particles that are most likely to trigger an asthma attack.
EJ can easily cover an area up to 1,250 square feet. That makes EJ ideal for bedrooms, offices, living rooms, basements, and other large living areas.
Just how big is 1,250 sq ft? For your reference, the average size of a house bedroom is just 219 sq ft.
At fan speeds 1–4, EJ is whisper quiet at only a max of 33 dB (decibels). At fan speed 5, EJ won’t ever exceed 59 dB, which is normal conversation volume.
In other words, EJ is the quietest high-end air purifier on the market.
You’ll be happy to know that EJ has no distracting lights to keep you up at night. Why some other companies haven’t figured this out yet, we don’t know.
The main HEPA filter lasts 12 months (twice as long as the main filters for many other high-end purifiers). In many cases, the HEPA filter can last even longer with proper care.
The activated carbon filter lasts 8–12 months.
EJ HEPA filter replacements are $95.00 while carbon filter replacements are $79.00.
However, with their lifespan and the efficiency of EJ’s German EC motor, you’ll save an average of $168 per year in energy costs.

The Best Filters
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. The EJ air purifier has two filters – a 1” deep pleated activated carbon filter and a 3” deep main HEPA filter. Effective for gases for smoke and gas leaks (methane gas, sulfur gases, and many others).
Note: for heavy smoke or odors the HEPA filter can be removed and replaced with two additional carbon filters.
Formaldehyde Removal: 99.78% (48 hr test)
Sulfur Dioxide Removal: 99.39% (48 hr test)
Nitrogen Dioxide Removal: 99.97% (48 hr test)
The main filter is the same industrial filter that is trusted by hospitals and removes much more than any true HEPA filter.
If you remove the filters, the white HEPA filter should be inserted first with the black seal facing inwards (in the picture 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.
Pre-filter is 1" deep carbon pleated filter with our proprietary gas filter media that is effective for a wide range of gases and odors. We've improved our carbon filter to have 50% more carbon surface area to better remove all gases.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.
The 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.
Placement- we suggest placing the air purifier in the room where you spend most of your time. For most this is a bedroom where the unit stays plugged in and runs 24/7 or whenever you are in the room.
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.
Up to 1,250 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.
