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).

• 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.

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.

Room Size

Up to 1,250 sq ft with 2 air changes per hour. Results are AHAM verified.

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.
