User's Manual

How long does the filter last? The mod and mod jr. have one combination filter that includes pre-filter, HEPA based filter media, and activated carbon. The filter life is 12 months.

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 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 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.

Where is it made? The mod series are designed in the USA and assembled in China.

The Quietest Air Purifier In Its Class

Mod Jr Hepa Air purifier

Mod Jr. quietly cleans 363 square feet with 4.8 air changes per hour (878 square feet with 2 air changes per hour) so you can enjoy pure, clean air without breaking the bank or disturbing your sleep.

ENERGY STAR® certified for efficiency. When it's time to power down, simply press and hold the power button until it shuts off. It may take a few seconds due to the energy efficient motor.

Super simple to use with easy replacement filter changes. We haven’t added any unnecessary bells and whistles that cost you extra without providing any value.

An air quality sensor in the air purifier may seem like a good idea however they tend to give a false sense of security as they are low quality and located at the air purifier. It turns out a $2 sensor is not accurate like the quality sensors that cost hundreds to thousands of dollars. Plus, there’s no app taking up space on your phone.

If you want assurance that an air purifier will clean the air in your space look at the smoke CADR. This number is related to the room size the air purifier will effectively clean and is independently tested in labs with air sensors that cost thousands of dollars.

Just clean, reliable air at an affordable price without the gimmicks. Guaranteed to protect your health for years to come.
