There are 5 things every person needs to survive: water, food, shelter, sunlight, and air.
Our specialty is air. Or more specifically, clean air.
Although practically invisible, the air we breathe plays a critical role in our wellbeing. To achieve the longest, healthiest life (and to ensure the same for our families and pets), clean air is an absolute must.
In today’s world of pandemics, wildfires, seasonal allergies, and so much more, keeping your indoor air clean of allergens, pathogens, and pollutants can feel like an almost impossible task.
But it’s not a task you have to tackle alone. For more than a decade, we’ve specialized in engineering the highest quality, most energy efficient air purifiers to do the dirty work for you.
We’ve had a laser focus on this one important issue.
By the way, you visited us at just the right time because the mod HEPA Air Purifier you see today is our latest and greatest air purifier.
Continue below to learn all there is to know about the mod. Heads up: We believe in full transparency and providing you with everything you need to know to make an educated decision. Naturally, that means our page will be a bit longer than anticipated, but we promise that what you learn in the next 10 minutes will be worthwhile.
No air by-pass so all the air is filtered. This is a huge feature and is one reason we have superior air filtration performance. Other air purifiers often have openings that leak unfiltered air, making them inefficient (which means more energy needs to be used to clean the same amount of air, and more energy used means a higher energy bill).
Effective against viruses, bacteria, dust, pet dander, allergens, fine particles, smoke, VOCs, pollutants, and gases (methane gas, sulfur gases, and many others).
Latest Japanese engineered EC motor is quieter and uses up to 90% less energy than competing air purifiers.
Control by touch: simply slide a finger along the fan speed arc to set the precise air flow. Compact and lightweight: at just 23 lbs, Mod is easy to move between rooms and it’s only 14 inches wide and deep by 25 inches high, fitting almost any space.

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.
Effective for fine particles, smoke and gases (methane gas, sulfur gases, and many others.)
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.
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 (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 1,312 sq ft with 2 air changes per hour. Smoke CADR tested up to 343 CFM.
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
Important: Remove the air filter from the plastic wrap inside the air purifier before use.
Note: To turn off you will need to press and hold the power button for 3 seconds
How long does the filter last? The mod and mod jr. have one combination filter that includes pre-filter, real HEPA, and activated carbon. The filter life is 6-9 months of continuous use.
When the filter light is illuminated, does it mean it’s time to replace it? The red filter light will illuminate after 4,500 hours of run time indicating it is time to check the real HEPA filter. We suggest replacing your filter when you can no longer see white filter media.
How do I clean my filter? Clean the filter with the brush attachment of your vacuum cleaner or wipe with a damp cloth. Cleaning your real HEPA filter every few months can prolong filter life and help you get the best value for your purchase.
How do I replace the filter?
1. Turn off and unplug the purifier.
2. Flip the purifier upside down and place it on a non-scratch surface with the base facing up.
3. Move the slide switch to the right to unlock. Grab the base and turn it counterclockwise to loosen. Lift off the base of the purifier. Pull the handle of the air filter to lift it out.
4. Insert new filter with handle facing out. Twist the handle slightly to ensure it is fully seated in the housing.
5. Place the purifier base back on the housing lining up the arrows of the base. Turn the base clockwise to tighten. Move the slide switch to the left to lock. Flip the purifier over onto the base and plug back in and turn on.
How do I reset the Filter light? Press and hold the filter on the interface until the light goes from red to blue.
What if my interface is not adjusting the fan speed? It takes a moment for the interface to recognize touch, so place your finger on the fan speed scale until you see the interface light up. Then you can adjust the fan speed to your liking.
Why is the fan speed decreasing for a moment without me touching it? When the unit is operating at a high speed continuously, the motor will slow down intermittently to extend the life of the motor.
How do I turn my purifier on? Press the power button for a moment and release. Do not hold it down. The interface will light up when powered on.
How do I turn my purifier off? Press and hold the power button for a few seconds.
How can I clean the outside of my purifier? Use a clean, dry, soft cloth to wipe the external surfaces. Never use any chemical or harsh cleaners.
