"Breathe The Good, Filti The Bad"

Updated: Aug 6


So says Filti, the manufacturers of a new face mask filter material created in response to the COVID-19 outbreak in the United States in the Spring of 2020. They are a local Kansas HVAC company that was making washable and reusable furnace filters before the pandemic. Shortly after the US outbreak, all that changed. They refitted their entire Oklahoma plant to produce a thin "face mask filter" with their proprietary nanotechnology process.


Rydge, a YouTube channel formed by "a team of firefighters in Tennessee with a diverse skillset and a goal to equip the frontline of emergency services with effective technology." reviews this material in a multiple part series. In the unboxing video, you get a chance to see what comes in the mail. In Ryder's second video, they deconstruct the fabric and talk about the science behind it as well as reveal their discovery that Filti is fusible.

The most revolutionary feature of Filti's fabric is that the filtration is achieved through nanotechnology and not an electrostatic treatment. Nanotechnology cannot be washed away as an electrostatic treatment can. electronicsNmore, a YouTube channel that describes itself as "a helpful & educational channel" with over 383K followers, expresses excitement about the advantages of Filti in their review of the material.

Filti says the face mask material can be sanitized, but not washed like their furnace filters. They recommend using moist heat, one of the CDC Recommendations for Crisis Standards of Care in their guidelines for Decontamination and Reuse of Filtering Facepiece Respirators. At $1 a square foot, it may be affordable enough for some to use as disposable materials.

Filti has been tested independently by TSI and filters 95% of particles down to 0.03microns, the same as an N95. Mask FAQ, a website run by Chloe Schempf of Michigan Mask Response, currently has data supporting one layer of Filti and one layer of cotton rip-stop producing an 84% filtration and two layers producing over 97%. Not only has MaskFAQ deemed Filti to be far superior in filtration than any other materials meant to be near your face. Filti also performed beautifully in breathability, which garnered Filti the top spots in the study for efficiency as a face mask filter material.


For all these reasons, #MutualAidMasks has determined Filti to be the most desirable non-medical grade material to which we have access to make a better mask. Filti filters help #MAM fulfill its mission "to reduce the harm associated with COVID-19 by offering education on personal protective measures and distribution of do-it-yourself personal protective equipment (DIY PPE) to promote the mitigation of the spread of COVID-19.
