Air FilterUser's Manual
With the mod we combined three filters into one – a mesh pre-filter, true HEPA filter and a layer of activated carbon. This cylindrical filter has a convenient carry handle so you never have to touch the dust that has accumulated on the filter. The mod air filter also has seals on both ends to ensure no air bypasses the filter so you can breathe the cleanest air.
The carbon layer will adsorb VOC's. In a 2 hour test, the mod removed 88% of formaldehyde.
Note: Dust will accumulate on the outer mesh screen of the filter. This can be vacuumed or wiped with a cloth to clean.
Independent lab tested in the USA per the EN-1822-5 test standard in Aug 2020. Removal rate is the percentage of particles removed with each air pass for a given particle size.
0.02 microns = 20 nanometers
mod (like our EJ and Erik series) has the best, latest 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.
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.
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.).
Up to 1,250 sq ft with 2 air changes per hour.
Perfect for large home living areas, offices, healthcare facilities, nursing homes, and any other small to large square footage space that requires portable air cleaning.
The mod 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.
CADR (Clean Air Delivery Rate) is the industry standard for ability to reduce smoke, dust, and pollen particles in the 0.10 to 11 micron (μm) particle size range and basis for assessing room size coverage.
Tested per ANSI/AHAM AC-1 by Intertek ETL

The mod HEPA Air Purifier for Allergies is made for this.
It’s that magical time of the year again, when the leaves begin to change and you bring out the apple cider.
Unfortunately, with fall also comes 200+ allergens (like ragweed) that float in the air we breathe. While these allergens aren’t visible to the naked eye, they certainly make themselves visible by giving us unbearably itchy eyes, a mean cough, a runny nose, and never-ending sneezing.
In the image above is a single pollen particle magnified by 400x. Surprised to learn how something so small can wreak so much havoc on our bodies every allergy season?
Perhaps the reason why is because we’re unknowingly making matters worse. Everytime we step into our homes or offices we track in more of these allergens. Once inside, they don’t have many exits and they collect, making your indoor air 2–5x worse than outdoor air. This could be why your allergy medication is falling short of expectations each fall.
According to the CDC, almost 20% of the US experiences hay fever alone each year. That’s over 60 million Americans (or 1.5x the population of California). In other words, you are not alone in this fight—seasonal allergies are a BIG issue. To help combat seasonal allergies, the world-renowned Mayo Clinic recommends using a portable, high-efficiency particulate air (HEPA) filter indoors.
But not any HEPA air purifier will do.
There are a lot of air purifier brands out there, and we’re sure you’ve seen a couple of their commercials. Some of these brands make great looking machines with lots of bells and whistles. But the reality is that while these features can sometimes be nice, they can’t make up for what really matters.
When comparing air purifiers the #1 detail you need to research is the clean air delivery rate (CADR), which is a measure of how many cubic feet per minute (CFM) of air that has had all of the particles of a specific size removed. Can you guess how many other air purifier brands are willing to share their CADR numbers with you?
We’re going to do something that those other brands are too afraid to do—share our CADR numbers with you right here in black and white:
mod HEPA Air Purifier CADR rates:
With a pollen CADR of 412 cfm, this means that the mod removes the pollen from a space measuring 412 cubic feet each minute. As an example, a 1,250 sq ft room with an 8 ft high ceiling is 10,000 cubic feet. 10,000 / 412 is equal to about 24 minutes. In other words, the mod can remove the pollen from a 1,250 sq ft room in just under 25 minutes!
Here’s another thing other brands don’t want you to know: they’re using AC motor technology that was first developed in the
1920s 1900s 1880s. Before TV, before radio, before World War I.
The mod, on the other hand, uses the latest Japanese engineered EC motor technology that is whisper-quiet and unmistakably efficient (up to 90% more energy efficient than the other guys). In fact, thanks to the mod’s unmatched ability to capture and trap allergens and other particles with ease, it can save you an average of Reveal per year on energy costs. That’s already 28% of the cost of the mod, meaning this air purifier will make up for its cost within 4 years (with an industry-leading 10-year warranty, you know it’ll do that plus more).
As you can probably imagine, achieving this level of performance was a difficult task. The one thing that we struggled with the most was figuring out how to engineer a compact air purifier that didn’t compromise on the filter quality, motor efficiency, and quiet operating volume that made us trusted by world-class organizations.
We considered everything.
We had to go back to the drawing board, and eventually we had our lightbulb moment: what if we use a cylindrical 3-in-1 filter (a single filter component that combines a pre-filter for large particles, HEPA filter for fine particles, and activated carbon filter for smoke and VOCs)? See the mod in action:
Each day we breathe in 20,000 liters of air. Twenty thousand.
But much of that air is not clean. In fact, indoor air can be 2–5x worse than outdoor air because our homes and businesses act as traps for dust, pollen, bacteria, viruses, and more.
This is a disastrous equation for those of us who suffer from seasonal allergies or asthma, and those of us who get sick easily. That’s why a high quality HEPA air purifier is a necessity for your home or business.
That’s exactly what I (Peter Mann, founder of Oransi) realized more than a decade ago. Before the mod HEPA Air Purifier. Before Oransi. My son was suffering from asthma and I knew a high quality air purifier would help. The only problem? Most of the air purifiers I saw didn’t disclose all of their performance stats and they focused on all of the wrong things (trendy gadgets and looks instead of ability and efficiency), which made choosing one a difficult task.
That’s when I decided to take matters into my own hands and build an air purifier brand that put performance and transparency first. Turns out, that’s exactly what people care about most, and more than a decade later we’re still here because we haven’t lost sight of that.
When you order the mod HEPA Air Purifier, just know that you’re getting a high-efficiency, ultra-powerful, and whisper-quiet air purifying machine that just happens to also look good. From day 1, the #1 focus was performance because when it comes to the air you breathe your health matters most. Everything else was secondary.
