Oransi Mod Hepa User Interface


Meet the Oransi mod HEPA, the latest addition to Oransi’s growing family of high-end air purifiers. The new Oransi mod HEPA offers the same outstanding particle collection as their award winning EJ120 model, but at a more affordable price. If you are not concerned about VOCs and other gaseous/chemical pollutants, then the mod HEPA may be the air purifier for you!

The Oransi mod HEPA effortlessly captures traditional allergens such as dust, pollen, mold spores and pet dander, but can also handle more harmful particulate pollutants like PM2.5 particles, tobacco and wood smoke particulates, vehicle exhaust, ultra-fine aerosols and airborne pathogens. The mod HEPA’s simple and intuitive controls make this air purifier a pleasure to own and operate – so simple in fact, that you can skip the user manual!

In developing the mod HEPA air purifier, Oransi’s engineers created a design that is both eye-catching and functional. Unique features include a 360 degree air intake from the bottom of the unit that sets up a push-pull airflow within your living space and permits convenient placement anywhere within a room. A striking glass interface on top of the air purifier facilitates quick and easy fan speed adjustments - simply slide your finger along the arc to increase or decrease the airflow rate. The Oransi mod’s HEPA’s flip-up handle is another great design element, allowing for easy portability, with a second handle built into the filter itself for contactless filter changes. Simply brilliant!

The Oransi mod HEPA air purifier uses a 3-in-1 filter that incorporates a mesh pre-filter, HEPA filter and activated carbon filter combined into one convenient and economical filter. The mesh pre-filter is designed to capture larger particles so that they don’t clog the subsequent filters, prolonging their useful life. The large MERV 17, medical-grade HEPA filter is certified to filter particles down to 0.3 microns with an effectiveness of 99.97%+. However, this no-compromise filter goes one step better, capturing nanoparticles with 99.4% effectiveness at 0.02 and 0.1 microns. This makes the Oransi mod air purifier a great choice for handling airborne pathogens, smoke particulates and other nano-sized particles. Finally, the activated carbon layer in the Oransi mod combo filter is able to adsorb light chemicals and gases.

Oransi mod HEPA filter change

The Oransi mod HEPA air purifier draws contaminated air into the unit from all directions at the bottom, and then delivers ultra-clean air back into the room from the top of the unit. This creates a “push/pull” dynamic within the room, pushing ultra-clean air constantly into the room, and forcing the dirty air to be pulled towards and into the air purifier. The mod HEPA’s 100% sealed filtration system guarantees that no contaminants can bypass the filtration system, a problem seen all too often in even the most expensive of air purifiers. It’s great having a well-rated HEPA filter in your air cleaner, but if half the air isn’t going through the filter, then filter performance test results are meaningless.

The Oransi mod HEPA’s Japanese-engineered EC motor and fan assembly also make it a standout in the expanding sea of air purifiers on the market. This state-of-the-art EC (Electrically Commutated) motor offers 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. The mod unit can produce up to 338 cubic feet of clean air every minute, providing 4 complete air exchanges every hour in a 634 sq. ft. area. As an added bonus, EC motors have no bothersome motor hum to disturb your peace and quiet.

Speaking of quiet, the Oransi mod HEPA is one of the quietest air purifiers on the market at any given air flow rate, ranging from 20 dB to 60 dB. In addition, the variable speed motor allows everyone to find the perfect speed and noise level for their individual living space, (i.e., you are not limited to low, medium or high).

Love the mod but have a smaller space? Then the newly introduced Oransi mod jr. HEPA might just be perfect for you! A scaled-down version of the regular mod HEPA unit, the Oransi mod jr. air purifier features the same outstanding air filtration capabilities and features of the regular mod unit. The mod jr. is slightly smaller (22” high with a 12” diameter), and slightly quieter on high speed, the upside of a less powerful motor. Able to perform up to 4 complete air exchanges per hour in a 440 sq. ft. room on the high speed setting, the Oransi mod jr. HEPA is still one powerful little air purifier, yet compact and light enough to move between rooms if desired (just 18 lbs).

To sum up, both the Oransi mod and Oransi mod jr. are excellent choices for those who want a high-performance air purifier with a contemporary look, backed by one of the best warranties in the business - a full 10-year manufacturer’s warranty. The mod HEPA is perfect for the main living space in your home (living room, family room, rec room), as well as offices, healthcare facilities, classrooms and retail spaces, while the mod jr. is ideally suited for bedroom use, small bachelor apartments and student dorms.

“I am emailing to say “thank you!” My Oransi mod HEPA order was processed and shipped very quickly and I love this air purifier – I noticed an immediate difference in the air quality within my home (within an hour-ish). I will be grabbing a few filters for my unit in the future and should my workplace decide to purchase an air purifier, I will definitely be ordering again from Modern Alchemy Air Purifiers.”
Jo-Ann H, The Pas, MB

“We have Oransi mod HEPA and mod jr. HEPA air purifiers at home and in both of our offices and we love them. The one we just ordered is a gift for a family member who admired ours. Your service, and the quality of the products you offer, make it our pleasure to be a repeat customer! Thanks so much.”
Joy K., East Pennant, NS

** An Important Word on Air Flow Rates and Room Coverage for the Oransi mod and mod jr. Air Purifiers:

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 mod HEPA air purifier be used in rooms of up to 317 sq. ft. (for premium cleaning) or 634 sq. ft. (for general purpose filtration), and the mod jr. in rooms up to 220 sq. ft. (for premium cleaning) or 441 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.
