What's the Deal with those PM2.5 Filters?

Jul, 28 , 20 - Stacey Malo

I wish those filters would be banned from the marketplace. They give people a false sense of security and therefore may put more people more at risk. 

They are not certified by a lab. A Chinese manufacturer used a stamp on this cut material, but there is zero lab certification of these products or the packaging. It's all a sham. 

There is zero regulation of this stuff in China. Who knows what's in this product and what the effect is. No one is regulating. Don't trust it. 

Activated carbon works to filter microparticles. There is not enough activated carbon in these filter products to actually be of any benefit. Again, there's no lab certification or ingredients list on these things. Fraud.

How Shellfish Keep Your Face Mask Effective and Comfortable

Jul, 18 , 20 - Stacey Malo
Happyface masks have several unique properties. One such special property of the Happyface fabric is an application called Chitosan. The chitosan is used as an application on the surface of the fabric used to make Happyface masks. Chitosan is naturally non-toxic, biodegradable, and biocompatible. The application used on the Happyface fabrics is EPA certified. This application makes the fabric anti-microbial, which keeps your mask odor-free, bacteria-free, mold-free, and will prevent skin-blemishes.

What Makes a Mask Breathable

Jun, 17 , 20 - Stacey Malo
Airveil filters, because of their nanotechnological structure, are the most breathable of filters. Their pressure drop (breathing resistance) is nearly unnoticeable. The unique abilities of nanostructure are better explained in the previous blog post, How Nano-Fibers Work for Air Filtration. This technology allows for the Airveil filter to be as effective as an N95 or HEPA filter with only one layer of material. The typical N95 rated filter is layers of spun-bond polypropylene. Obviously, the more layers required to obtain a high standard of filtration, the less airflow will be able to get past to the wearer. Airveil filters are a single layer of material, making them extremely lightweight, breathable, and they can even be washed and reused!

How Nano-Fibers Work for Air Filtration

May, 30 , 20 - Stacey Malo
Particulate matter at .3 microns is the most difficult to capture. The COVID-19 virus, at roughly .01 microns, is easier to capture due to electrostatic charge or Browning Diffusion (see first graphic above) than the larger particle. Air filtration (such as N95 and N99) is measured against the percentage to capture .3 microns. For instance, an N95 face mask is 95% effective in capturing .3 microns. Capturing this exact particle size is the gold standard of mask filtration. Larger than .3 and smaller than .3 microns are less worrisome as there is an even higher capacity to capture those sized microns (including a virus at .1 microns). The main benefit of electrospun nano-fiber filtration is the high efficiency of filtration with low pressure drop (breathing resistance). An effective product, comfortable to wear.

The Danger in Sterilizing Masks

May, 02 , 20 - Stacey Malo
This debris clogs up the pores of the filter material. Disinfection is another name for sterilization. These methods will deactivate a virus and kill bacteria, but the filters won't necessarily be cleaned from airflow blockages. The "clean" masks still have a lesser lifespan than that of a new mask.
