No mask can completely guarantee protection against infectious disease. A good quality masks can reduce the changes if worn properly.
We are definitely 10 X more effective than most reusable cloth mask on the market and can back up our performance claims with verified testing. Our results show that we capture 99.3% of microscopic particles.
It all depends on what kind of environment you live in and how often you use it. The typical shelf life KandyMask is around 6 to 12 months. Once you notice it becoming harder to breathe through the material it is usually the time to replace it.
The dual valve system opens when you exhale to let moisture out making the mask more comfortable to wear for long periods of time. The valve automatically closes during inhalation to prevent harmful airborne contaminants from entering your lungs. By using valves on the mask the internal heat of the mask is reduced by about 10 degrees.
We also offer a non-valved version of KandyMask as well.
We have been in the air filtration business for over 12 years and have designed our mask with materials used in the top performing mask in the world.
Cloth masks offer little protection to the user and only offer protection to others from the users droplets. The materials used in cloth masks are not meant for respiratory protection.
KandyMask has been awarded GB/T 32610-2016 for daily protective use.
There are 4 grades to this test A, B, C and D. KandyMasks is considered an A grade mask for daily protective use which requires a 90% efficiency rate and our result shows we protect against 99.3% of particles.
The size varies on a few factors like the size of our face and age but we have made 4 sizes that can fit any person. If you are caught between sizes we recommend choosing the smaller of the 2 sizes as it will provide a tighter seal.
We don't believe that masks with replaceable filters are a good choice. A masks should have filtration materials that cover the entire masks right to the seems and not just being inserted into a small filter pocket.
Many companies are creating cloth masks with little inserts and buying cheap PM2.5 filters to be inserted. This is a huge problem right now as it is misleading people into believing they are protected buy using the world filter.
We have never heard of any mask being independently test to meet any type of high standard.
The unfortunate answer is that masks solely made of cloth do not work well. Many companies have jumped on the cloth mask band wagon during the pandemic.
Here are the styles we are seeing that don't offer the right protection
Cloth Mask, multiple layers of protection
Cloth Mask with PM2.5 Filter insert
Cloth Mask with Carbon filter insert
These type of masks typically
Don't protect the user from airborne pathogens
Only protects others from your own droplets
The only exception to this rule would be if the mask company could show independent study showing their own mask performance. This is not a filter material performance certificate but the entire mask performance certificate. Many companies are showing off the filter manufacturers testing report but this in no way means that the entire masks is effective.
Here is an a link to the only independent study we found that compares cloth masks with medical masks. Basically nurses were given cloth masks in one hospital ward and medical masks in the other hospital ward. The rate of infection was very high in the cloth masks ward and the reports warns against wearing cloth masks for infectious disease prevention, primarily because they lack proper filtration
