As a result, when someone wearing a mask with a valve coughs, sneezes or breathes forcefully, bacteria and viruses can pass directly through the valve and out into the air. To avoid this, some masks add valves to quickly expel air when exhaled, but these valves typically have no filtration, and thus offer no protection to others. This means you have to inhale and exhale through all these layers AND the fabric of the mask with each breath, which can be hard work! This can also cause air to leak around the edges of these masks, allowing airborne particulates and pathogens to pass through unfiltered. Many conventional masks use filters with up to 4 or 5 layers. What's the difference between HALOmask and a mask with valves? Our high-tech, paper-thin HALO NanofiltersTM feature a proprietary вЂnano-matrixвЂ™ that blocks virtually all smoke, dust, pollution, pollen, particulates and pathogens. Viruses and bacteria are thousands of times smaller than the strands of cotton or synthetic thread in home made cloth or non-filter masks, allowing airborne particles to pass directly through. Mask Questions What is the difference between HALOmasksв„ў and simple masks that I can buy or make at home?ДЄccording to recent studies, simple cloth masks and masks without filtration technology do not stop viruses or bacteria. More information and test results can be found on our filters page. Yes! The HALOmask and nanofiber filters are tested and certified to Nelson Labs standards to 99.3% particulate efficiency at 0.1 Microns, which exceeds N95 standards. It's not nanofiber particles - so there are no 'pieces' that can be inhaled. This nanofiber matrix is made up of several very, very long fibers weaved together. The HALO Nanofilter is composed of a microscopic nanofiber matrix sealed between two layers of inert backing material. Is there any risk of breathing in nanofibers from my HALOmask? In each HALOmask there are up to 15 miles (24 km) of nanofiber in each woven Nanofilter! The unique structure of this вЂinvisible matrixвЂ™ physically captures virtually all airborne particles and pathogens - from smoke, dust, pollution and pollen to bacteria and viruses. Nanofibers form dense spider web-like structures which have an advantage over conventional filters due to their incredibly large surface area and miniscule pore size. Nanofibers are extremely small fibers вЂ“ more than a thousand times thinner than a human hair, and individually invisible to the human eye. What is HALO Nanofilter technology and how does it make HALOmask more effective than other masks? For regular and occasional use (such as commuting, shopping, traveling and gardening) replacing your mask filter every 2 вЂ“ 4 weeks will keep it fresh and functioning efficiently. How often do I need to change my HALO Nanofilterв„ў?ДЇor maximum protection we recommend weekly replacement of filters for people in direct daily contact with the general public or people with higher-risk conditions. Please continue to follow the guidance and orders issued by local government authorities and workplace/institutional instructions and standards. To minimize your risk of infection with COVID-19, wear your HALOmaskTM in conjunction with everyday preventiveВ actions, including good nutrition, frequent handwashing and social distancing. Medical mask certifications only apply to face masks that are single use and disposable. Unlike most facemasks, HALOmask not only blocks the inhalation of droplets, particles and pathogens, but also prevents the exhalation of respiratory droplets by the wearer.Д«ecause HALOmask is not categorized as a medical device, certification by the FDA and NIOSH is not required. Droplets can land on people who are nearby and be inhaled into the lungs.

By comparison, the Covid-19 virus measures approximately 0.125 microns in diameter. In testing, HALO Nanofilters proved effective at capturing over 99% of airborne particulates and pathogens down to 0.1 microns. While no facemask can guarantee 100% prevention of exposure to any virus, HALOmaskвЂ™sВ revolutionary HALO Nanofilter has been independently tested by Nelson Laboratories, a leading provider of microbiological and viral testing and analysis.
