Oransi EJ120 cross section


Compact, quiet and powerful. Three words that succinctly capture the essence of the Oransi EJ120 air purifier. The award-winning EJ120 is the smaller version of Oransi’s flagship model, the Erik 650A, and Oransi’s exceptional design, engineering and attention to detail have made it a stand-out in the consumer marketplace. Since its launch, the EJ120 has won numerous accolades, including the best air purifier tested to date by Modern Castle (2019), the Best Air Purifier for Large Homes by CNN (2019) and the Editor’s Choice – Best Air Purifier (2019) by Women’s Health Magazine.

In designing the EJ120 air purifier, Oransi has steered clear of several high-tech design trends, making a simple to use, three-stage air purifier that focuses on doing the job at hand extremely well, without a lot of bells and whistles. The first cleaning stage in the Oransi EJ120 air purifier is a vacuumable mesh pre-filter that filters out any large particles in your environment (e.g., pet hair, textile/wood dust, carpet fibres), preventing the subsequent more expensive filters from becoming prematurely clogged.

Oransi recently redesigned the second stage activated carbon filter in the EJ120 air purifier from the ground up. The new, 1” pleated polyester spun-bonded high-efficiency carbon filter now offers 50 times the composite media surface area for improved chemical, gas and odour adsorption. This pleated carbon filter is a step up from granular carbon beds, increasing the density and surface area for adsorption of gaseous pollutants and delivering a longer effective filter life, without restricting air flow through the air purifier. The EJ120 pleated carbon filter has also been specially treated so that it will not release odours as it fills up.

Recognizing the inherent difficulty that most activated carbon air purifiers have with handling formaldehyde, Oransi developed a proprietary treatment process that amps up the ability of the coconut shell activated carbon in the EJ120's filter to adsorb formaldehyde to a chart-topping 99.78% (48 hrs). Independent lab tests also show that this new filter is able to remove sulfur dioxide and nitrogen dioxide with similar effectiveness levels. The Oransi EJ120’s exceptional gas and chemical capabilities make it perfect for safe-guarding homes located near major highways, as well as in wildfire regions, agricultural areas, industrial areas and highly polluted cities. The EJ120 can also handle VOC off-gassing, fumes and toxins from household cleansers, tobacco smoke, and other gaseous pollutants with ease.

The third cleaning stage in the Oransi EJ120 air purifier is a medical-grade, MERV 17, 2.25 inch deep HEPA filter that is certified to filter down to 0.3 microns with a guaranteed minimum effectiveness of 99.97%. However, independent laboratory testing confirms that this exceptionally made HEPA filter has a better-than-HEPA capture rate of 99.992% to 99.996% at 0.3 microns and 99.8% at both 0.1 and .02 microns. With the Oransi EJ120, you can say goodbye to ultra-fine dust, pollen, mold spores, pet dander, dust mite by-products, PM2.5 particles, combustion/smoke particles, airborne pathogens and other particulate pollutants that may be causing respiratory system distress.

The Oransi EJ120 air purifier draws contaminated air into the unit via its large front grill and through its 100% sealed filtration system, returning ultra-clean air into the room from exit vents located on the sides and top of the unit. This design eliminates “shortcutting” (i.e., freshly filtered air being immediately drawn back in to be re-filtered), a common problem that occurs in air purifiers when the air outlet and intake are positioned too closely together. The engineering of the Oransi EJ120 also allows it to be positioned flat against a wall for space-challenged rooms.

Deemed the “Tesla of air purifiers” by the press, the Oransi EJ120 is certainly worthy of the title, primarily because of the superb, German-made motor and fan at the heart of the unit. The motor in the EJ120 is an advanced EC (Electrically Commutated) motor that delivers higher air flow rates, quieter operation, lower energy consumption and greater reliability than the cheaper AC motors used by virtually every other air purifier manufacturer. And to top it off, there is no annoying motor hum!

So, how quiet is the Oransi EJ120? Virtually inaudible. On its lowest fan speed setting, the decibel level in a sound chamber can’t even be measured. On Speeds 2 and 3, the EJ120 is still quieter than any other air purifier that we sell (19 to 24 dB). Even on the highest speed, it is quieter than many other air purifiers are on low. Since many will choose to use the Oransi EJ120 in the bedroom, the company has even made a point of avoiding distracting LED lights on the unit that are not conducive to sleeping. If you are sound-sensitive or a light sleeper, but still want premium filtration performance, the EJ120 is the air purifier for you!

And lower energy consumption – really? Yes. Energy Star qualified at a maximum power usage rate of only 57 watts, the EJ120 uses less electricity than any of the other high-end purifiers on our website. The EC motor in the Oransi EJ120 consumes up to 90% less power than traditional AC motors, adding up to significant long-term cost savings. If energy savings are top of mind, then you will love the Oransi EJ120!

Okay, that all sounds good, but can such a compact air purifier really cover my open-concept living space? Well, this is where the Oransi EJ120 really shines. Despite its diminutive stature (only 1.5 ft tall, with a 17” x 10” footprint), the EJ120 air purifier can provide up to 2 complete air exchanges every hour in a 1250 sq. ft. area. However, those with allergies, asthma, ambient smoke or VOC issues are better off using it in a 625 sq. ft. area to provide 4 air exchanges per hour. For people with severe respiratory/medical conditions or chemical sensitivities, the Oransi EJ120 can provide clean-room quality air (8 complete air exchanges per hour) within a 310 sq. ft. space. Small and mighty, indeed!

The “no-frills” LCD control panel located on the top of the Oransi EJ120 allows you to select from five fan speed settings, and has an indicator that tells you when to replace the filters. Changing the filters is simplicity itself, with no tools required! Simply pull open the hinged front panel of your Oransi EJ120 via the handle, remove and discard the old filters, install the new filters and close the door. By pressing and holding the Filter Reset button on the top display panel for a few seconds, you will be all set for another 12 months of uber-clean air. Because the carbon filter is independent from the HEPA filter, it can be changed more often if desired, for example, when used in spaces containing exceptionally high concentrations of chemicals and gases (e.g., in new homes, during home renovations, in artist’s studios, during active wildfires, etc).

The Oransi EJ120 air purifier is made in the USA and built to last. The EJ120’s all metal construction guarantees a long and useful life, and is backed by a full 10-year manufacturer’s warranty. The EJ120 has a recessed handgrip for easy mobility, and four feet at its base to ensure stability. If you are looking to use this exceptional air purifier overseas, the unit can be custom-built for 220V use at no additional charge.

The Oransi EJ120 air purifier is the definitive choice for those looking for pristine indoor air, and is ideal for use in bedrooms, large living spaces, basements, offices, apartments/condos and art studios. With a timeless black and white colour scheme and a minimalistic design, the Oransi EJ120 is the picture-perfect choice for almost any setting.

“This is a Thank You letter and also a review of the 2 Oransi EJ120 units I have ordered from you. The first one arrived on April 21st and started working right away, so well that I ordered the second unit on the weekend since there are 2 floors and my townhouse is about 65 years old and needed this. I noticed the air quality being much better already after a few days. Previously I had 3 other air purifiers, Blueair, IQAir and GermGuardian, but the Oransi EJ 120 works better than any of those combined. Again, I recommend this unit for anyone with concerns about air quality because this unit is really working perfectly and worth every penny. Also excellent Customer Service!”
Sandor S. London, ON

“Thank you for the Oransi EJ120 air purifier! I received it last Friday, and there’s been a noticeable improvement to air quality in the modular - significantly LESS irritation with breathing, sore throat, headaches, fatigue, fogginess, migraines...and much BETTER rest & sleep, more energy and clearer thinking during the day. I would highly recommend this product to anyone experiencing sensitivity to “off gassing,” chemical smells and odors in a new modular home or building.”
Judy C, Kelowna, BC

“I was very pleased to receive my Oransi EJ120 earlier than I had anticipated. The first night, it ate the dust on my bedroom dresser! And very quiet! I recommend it very highly. Thanks so much for your service.”
Dawn M, Ottawa ON

“I purchased an Oransi EJ120 air purifier from you because we were having issues with smoke particulates from our wood stove. I just wanted to let you know that the Oransi is working very well for this purpose and is very quiet. Thank you for suggesting it.”
Bruce L, ON

“I was having an issue with high VOC levels in my house. Shortly after I began running our three Oransi EJ120 air purifiers, the VOC count in the house dropped from 150ppb to less than 50ppb. Thanks again for the air purifiers.”
Lucas F, Oakville, ON

“My Oransi EJ120 air purifier was a godsend during the wildfire smoke season last year!”
Helen M, Vancouver, BC

“The Oransi EJ120 - Looks great. Quiet as hell.”
Steve D, Toronto, ON

“The Oransi EJ120 air purifiers I purchased have arrived and the two for my house are working well. I can already feel a difference. Will likely save a fortune in Kleenex!”
Fredric G., Brampton, ON

“I ordered three Oransi EJ120 air purifiers from you and have been operating them 24/7 to off gas my new home. They are running well and seem to be doing the trick!”
Jason I, Toronto, ON

“We bought 2 of the Oransi EJ120 units from you in November. We really like them, they do an excellent job!”
P. Armstrong, ON

“My Blueair Pure Blue 211+ air purifier works great! I sleep better, am up earlier in the morning and feel a lot more alert and energetic. My lungs feel more relaxed and less congested, and I tend to take deeper breaths. It has only been 5-6 days since I received the unit! The Oransi EJ120 air purifier also works amazingly! My mom and brother are really happy with it. My mom is breathing easier and sleeps better through the night. The air smells cleaner too. It was the best decision to purchase both units!”
Tina K., LaSalle, QC

** An Important Word on Air Flow Rates and Room Coverage for the Oransi EJ120 Air Purifier:

Many retailers and manufacturers overstate maximum room coverage figures by calculating them with air flow rates measured without filters installed (i.e., fan output) or with too low a number of air exchanges per hour to properly clean the room. Modern Alchemy Air Purifiers believes in stating the actual delivered air flow rates for the air purifiers we sell, as well as realistic room coverage figures calculated at effective air cleaning levels. Accordingly, we recommend that the Oransi EJ120 air purifier be used in rooms of up to 310 sq. ft. (for premium cleaning) or 625 sq. ft. (for general purpose filtration).

Note that air purifier performance should not be judged by air flow rates and room maximums alone. Many features that make an air purifier more effective at cleaning the air actually reduce the air flow rate. For example, higher grade HEPA filters, well-sealed filtration systems and large amounts of carbon all increase air resistance and reduce delivered air flow rates.
