F3 High airflow + Active carbon filter - 3 Pack

Upgrade to the F3 High Airflow + Active Carbon filter for improved breathability.
Using electrostatic technology to capture up to 99% of dust, dirt, pollen, mold spores, allergens, bacteria, and odors, the F3 gives you up to 50% better breathability than the F1 Standard filter.
For all-day wear or active projects like building, landscaping, or demolition, upgrade your filter to the most breathable RZ filter with odor-reducing active carbon.

- Up to 50% better breathability than the standard F1 filter
- Filters up to 99% of particulates down to .1 micron in size
- Active carbon element reduces odors
- Best-in-class filtration with 360° seal
- Performance far exceeds that of homemade masks, bandanas, cloth masks, and paper masks

The F3 filter adds a 5th layer of technology featuring electrostatic filter microfiber media designed to be highly breathable and protective, capturing up to 99% of particulates through static electricity.

The active carbon element removes air pollutants, including volatile organic compounds (VOCs), odors, and other gaseous pollutants from the air by trapping gas molecules on a bed of charcoal.


Against Certain Non-Oily Particles
Dust Masks


All RZ filters have been independently tested by an international microbiology lab, with results showing RZ filters exceed the NIOSH N95 filter efficiency standards.
We test both the filtration and breathability to ensure we're creating a product that offers the best of both, so you can feel confident and comfortable while you work.


The life expectancy of your RZ filter depends on many variables, such as; particulate exposure density, particulate exposure duration, and user breathing rate. Below are our general guidelines:
- 20-30 hours of continuous use in heavy dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.
- 30-40 hours of continuous use in light dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.
- 50-60 hours of continuous use when protecting against allergens, pollutants, odors, etc.


Suggested Uses:
High-intensity dust, fumes, odors, smoke, and pollen

Depending on the type of activity you're doing, filters are suitable for anywhere from 20 - 60+ hours of use. When the time comes to replace your filter or valves, follow this step-by-step process.

Step 1:
Turn the valve on the inside of your mask counterclockwise until the back releases from the front. Grab a new filter to replace your used one, and now would be a good time to clean the outside of your mask if it's dirty.
Step 2:
Place the back of the valve with the clear diaphragm through the filter, then place through the mask material
Step 3:
Once the back of the valve is through both the filter and mask, grab the top valve and look where the inner indentations are. You will want to line up the tabs on the top valve with the indents on the bottom valve.
Step 4:
When the front and back of the valve connect together, turn the back of the valve clockwise about 90 degrees or until it can no longer turn anymore.
Step 5:
Repeat step 3 & 4 to the other valve.
Step 6:
Now your mask should be complete! If you are using the V1 valves, make sure the vent is facing down. If they are not, take off the front of the valve and make sure the brackets on the right (0 degrees) and left side (180 degrees).
