Can your masks guarantee against infection of viruses?
No mask is a guarantee against infection or the transmission of viruses or diseases. All masks SHOULD be used in addition to practicing CDC recommendations on hand washing and social distancing.
Why do I need a filter for the cloth mask?
Researchers compared how effective cloth masks were to medical masks and found 97% of particles penetrated cloth masks, 44% of particles penetrated medical masks, and <0.01-0.1% of particles penetrated N95 masks. Without a proper filter, cloth masks are ineffective and provide very limited protection from viruses.
What is the melt-blown paper you use in the filter? Why is it important?
The melt blown layer is the most important part of a mask, whether it's a surgical mask or N95. The melt blown material is made on 90-inch-wide conveyor belts, coated in layers of fine white plastic fibers that combined have the consistency of cotton candy. Each thread is simultaneously fed through one of thousands of tiny precision-formed holes. A blast of hot air on the other side fuses fibers together so tightly that while air can pass through the microscopic perforations between them, more than 95% of microbes can't get through. To offer best protection, our filter is made of TWO layers of melt blown cloth as well as other layers.
What is PM?
Particulate Matter (PM) are microscopic bits floating in the air that can be inhaled into the lungs, including viruses and bacteria.
Can I use KN95 masks at COVID-19 frontline?
KN95 is the Chinese equivalent of N95 masks and has been approved by CDC and FDA as alternative to N95 respirators for healthcare workers. For better result, use in combination with disposable surgical masks
