The KYMIRA K-Mask, with the integrated Nanofibre K-Filter, is designed to protect you from viruses, bacteria and environmental particulates, with a 99.6% filtration efficiency is that is rated as one of the best in the world.  Looking to help during the pandemic, KYMIRA researched and adjusted one of its existing technologies, it’s electrospun nanofiber material, with partner Radical Fibres. Having being asked to test many masks over the last few months I simply refused to work with most of the brands as they where unknown to me and we only work with brands we are aware of and having used this mask for a few days it certainly is one to check out, read about the mask below for more and check the video.

The Nanofiber K-filter:

Using a triple sandwich layer, nanofiber combination, the K-filters have been designed as a reusable, world class filter that will protect you and those around you.

Layer 1: Nanofibres capture viruses, bacteria and pollutants via electrostatic attraction

Layer 2: Activated carbon layer for environmental pollutants

Layer 3: Nanofibres capture viruses, bacteria and pollutants via electrostatic attraction.

The filters have been independently tested to ASTM F2100, ASTM FT101 and EN 1486 standards, certifying the 99.6% filtration rating*. The K-Filter offer its protection for 200 hours and for particles as small as 0.03microns. The effectiveness of the filtration level is due to this microscopic level of protection offered by the electrospun nanofibers, that ionically attract the particles before trapping them within the filter layers. To contextualise this, the Covid-19 virus has a particle micron size of 0.06 -0.5 and bacteria has a particle size of 0.3 microns. Healthcare workers on the front line have so far been using N95 rated masks that have a particulate protection size of 0.3 microns; so the wearer can feel confident in their protection when using the K-Filter.

The nanofibers within the K-Filter are made from biocompatible hydrophobic material which are elastic and electrostatic, meaning they are highly breathable, flexible and will not become wet with water vapour from breathing, this also reduces the carbon dioxide re-breathing occurrence that is a problem among even medical grade respirators.

This is why the KYMIRA K-Filter has proven itself to be one of the most effective air filters in the world.

The K Mask:

Utilising a combination of KYMIRA fabric technologies, they have created the K-Mask. More breathable, more comfortable, and more effective using cutting edge design and technology.

The K-Mask is designed to house the Nanofibre K-Filter and is made from KYMIRA Kynergy infrared fabric. The infrared fabric offers the wearer temperature regulation, due it it’s efficiencies in cellular excitation and enhanced circulation. The infrared fabric itself supports the wearer to cool or warm, depending on need and provides a cooling effect as you inhale, helping you stay comfortable during use. To note, KYMIRA KYnergy infrared fabric is safe to use, certified by the FDA as a class 1 medical device and CE marked.

Designed for comfort, prolonged use and protection, the fit and design of the K-Mask is second to none. Available in sizes small, suitable for smaller or teen sizes and medium/large, the mask is designed to fit close to the wearer, high up on the nose and wrapping around the cheeks towards  the ears to provide greater protection to and from the wearer.

The extended sides offer pressure balance, so that it forces the inhale and exhale through the viral filtration, even with use at high exertion or during coughing or sneezing. This makes the maskideal for not just everyday activities but for work, travel and playing sport too. The nose has a comfort strip underneath and a wired pinch bar so the wearer can ensure a close, comfortable fit, with attractive leather detailing. The straps fit around the head, fastening on the crown of the head and at the nape of the neck, providing comfort for long use that does not put pressure on the ears. The adjustable velcro fastenings and stretchy infrared fabric ensure the fit is close to the individual wearer. The close fit offers another ideal benefit, it reduces the occurrence and severity of glasses steaming whilst both are in use.

Cleaning, Reusability & Replacements

The Nanofibre K-Filters offer the wearer 200 hours of viral, bacterial and pollutant filtration protection. Once this time period is completed, the filter can be replaced with a fresh filter and the protection will continue.

The masks and filters can also be cleaned and reused during this 200 hour period. The masks and filters can be baked in the oven at 60 degrees and this will ensure that all trapped virus and bacteria particles are killed. The mask itself is also machine washable at 30 degrees. so it can stay looking fresh and clean (please note the filters should not go through the washing machine, unless your goal is to collect the pollutants in the washing machine itself).

The Nanofibre K-Filters can be used in the KYMIRA K-Mask, or any other reusable mask to increase the efficacy of any mask you have.

We mentioned how the K-mask matched up to the N95 but please see the graph below for a deeper look into how the K-mask matches up to masks currently available.
