The Craft Cadence Nanofiber Mask is a solid choice of mask even without all of its unique factors. When the extra aspects such as the use of ViralOff and Biostatic (Stays Fresh) along with the nanofiber filter media are taken into account the Craft Cadence Nanofiber Mask becomes a very unique mask. There is no other mask that offers all of these benefits – especially within this price range.

I really like this product. I love that they have not only used this material that is new to most of us, but have explained it really well and shown the data as to how it can be so advantageous
Craft Cadence Nanofiber Mask is the first mask in the world to combine Polygiene’s ViralOff® and Stays Fresh® technologies with a sewn in nanofiber filter that is certified to filter out 99% of particles at 0.3 microns (EN 149:2001 FFP3, equivalent to N99 rating)
Antiviral and Anti-odor technology
The outer layer of the mask is water repellent and treated with Polygiene ViralOff®. This is certified to reduce 99% of viruses (like hepatitus, Influenza, Corona) and other bacteria.
ViralOff® treatment is a Swedish technology from Polygiene. Craft Cadence is entitled to use the ViralOff mark as we have licensed the technology. Polygiene has tested the active ingredient against Influenza A, BirdFlu, Norovirus and Corona (SARS) over the years, and in all cases, have achieved 99% levels of virus reduction. Recently, it has been tested and proven to be effective against SARS-CoV-2.
For more details about ViralOff®, see here*ViralOff® is a treatment added to textiles to protect the treated article itself and is not intended to cure or prevent diseases.
The inner layers of the mask that touches your skin are treated with Polygiene Biostatic Stays Fresh® technology. This is certified antibacterial by IMSL (Industrial Microbiological Serives Ltd) to reduce 99% of odor causing bacteria.
Stays Fresh® applies a natural silver salt (AgCl, silver chloride) treatment that stops and breaks down odor-causing bacteria and fungi that builds up in the material. This means less need for washing, reducing water, energy and carbon emissions.
For more details about Stays Fresh®, see here.
The inner layer of the mask is a sewn in nanofiber filter which has been certified by Microtest International (MTI) Technology Laboratory to filter out 99% (99.41%) of particles at 0.3 microns in accordance with EN 149:2001 FFP3 (for EU), equivalent to a NIOSH N99 rating (for North America).
A full laboratory test result is available upon request by emailing firstname.lastname@example.org. An internal wash test of the filter material showed a reduction of filtration efficiency by 0.2% after 5 washes.
Nanofiber filters have been found to be superior to melt blown filters at retaining filtration efficiency. In a study by Ullah et al, researchers applied an ethanol solution to sterilise masks with Nanofiber and melt-blown filters. The nanofiber filter was able to retain much of its filtration efficiency at 98% even after 10 rounds of spraying cycles using an ethanol solution. By contrast, the melt-blown fabric began at a higher filtration efficacy rate of 99%, but that dropped to 62% after 10 spraying cycles.

Fit and comfort
Craft Cadence Nanofiber Mask has been thoughtfully designed to maximise fit, breathability and comfort, while minimising leakage:
- A wider design than most masks, allowing the mask to fit the contours of the users face and to minimise leakage on the sides
- A chin wrap for a secure and comfortable fit around the bottom of the user's face, again minimising leakage through the bottom. No more mask slipping.
- A long metal nose wire to stop glasses fogging up
- An adjustable earloop and soft earloop material for comfort around the user's ears
To further remove strain around the user's ears, a head strap is included which can position the tension to the back of the user's head.
Craft Cadence Nanofiber Mask has been created for the nuanced consumer who knows what they are looking for. Here is a table of our unique offering versus the rest of the market.
There are three sizes designed the meet the needs of 99% of adults, both men and women.
If you are in between measurements, it is always recommended to choose a size larger, as you can adjust the fit using the tightness using earloops and the provided head strap. If you get different results from (A) and (B), use of the size according to (A).
Nose to chin (A)
Use a tape measure to measure from around 2.5 cm (1 inch) from the tip of your nose to 2.5cm (1 inch) under your chin
Nose to earlobe (B):
Use a tape measure to measure from the tip of your nose to your earlobe. Our size guide is at the top of the listing.
