The industry standard metric for comparing air purifiers is called CADR (Clean Air Delivery Rate). It utilizes a combination of the filter efficiency and air flow to show the volume of clean air produced.
The challenge for shoppers is only about half of the air purifier brands publish their CADR numbers.
The CADR number is something you should ask about before buying an air purifier. If the CADR is not shown in the specs, we have noticed it is often because the brand doesn’t want it known.
Here are the certified CADR numbers for your EJ:
Tobacco Smoke CADR: 323 cfm (cubic feet per minute)
Dust CADR: 333 cfm
Pollen CADR: 360 cfm
How to Compare when a Product Doesn’t Show the CADR
Some brands will avoid/hide talking about CADR by focusing on how fast they can clean a room.
For example, you may see a 1,000 sq ft room coverage with one air change per hour.
Here’s how you can roughly equate this to a CADR:
The CADR is in CFM (cubic feet per minute). So, assuming the ceiling height is 8 ft, the 1,000 sq ft room has 8000 cubic feet (8 x 1,000). To convert to minutes divide by 60 to get to 133 cfm.
Assuming the filter removes 100% of the particles (which can be a big if), then the 133 cfm x 100% = 133 CADR.
Now, compare this 133 CADR to the 323-360 CADR for the EJ. Huge difference.
The secret to EJ’s effectiveness is our 2 filter process:
Filter 1 - A 1” deep pleated activated carbon filter: Proprietary carbon technology. Effective for smoke and gas leaks (methane gas, sulfur gases, and many others).
Formaldehyde: 99.78% removal (48 hr test)
Sulfur Dioxide: 99.39% removal (48 hr test)
Nitrogen Dioxide: 99.97% removal (48 hr test)
Filter 2 - A 3” deep main HEPA filter: Our improved HEPA filters are trusted by organizations that simply can’t risk pollutants of any kind (Hospital Operating Rooms, the Nuclear Industry, Containment units, and Laboratories).
By working together, these 2 filters create something quite extraordinary: A MERV rating of 17. That means our filter provides 99.97%+ protection. So yes, EJ will protect you and your family against mold, bacteria, and allergens like pollen, dust, and pet dander.
EJ will save 68% more in energy bills ($168/year). Good for the environment, and your wallet.
This tiny EJ is able to filter and purify 1,250 sq ft of space twice every hour. That means every 30 minutes your entire room will be fully sanitized. Talk about room service.

To ensure the highest quality and safety we make EJ right here in the USA.
(why this matters).
How is it possible to be so quiet and effective? We searched the World for the best motor and fan. Found it in Germany (at the same factory that makes Tesla engines). This incredible motor is quieter while still maintaining a high 384 pollen CADR air flow. The technology ain’t cheap (cost 10x more), but with performance and reliability that good we couldn’t pass up the opportunity. On its lowest setting, EJ is practically inaudible. On its highest setting, EJ is no louder than an AC unit.
Having to change filters isn’t fun. At the same time, air quality is of the utmost importance. Is there a way to maximize air quality without having to constantly change the filter? Yes, that’s what we’ve invented. With EJ120 you only have to replace the main filter every 12 months and the activated carbon filter every 8–12 months. And you don’t have to add a reminder, your EJ unit will flash a light when it’s time to replace.
Post purchase support: Buying EJ is the easy part. Once you buy it you'll want to get the most from it. You will have questions. And that’s where our Austin, Texas team comes in. You want to talk to a customer service team that only specializes in air purifiers. We've been providing phone support to customers for the last 14 years.

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 software and 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 and software 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.

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.
