Our masks have a sewn-in and washable nanofiber membrane, which is considered the gold standard in filtration efficiency.
Ours has been tested to maintain its efficacy for 50 washes, as proven by a Repeated Wash Test at the Taiwan Textile Institute.
Nanofiber membrane filters are often referred to as a “unicorn” filter for its unique ability to simultaneously achieve the following 3 properties below:
1. Powerful Filtration
Our filters have been tested by Nelson Labs and the Taiwan Textile Institute to block over 99.9% of particulate matter (PM) 10, 2.5, and 0.3. To put this into context, dust particles are PM8, bacteria is PM3, and pollution and viruses are < PM1.* Our standard of filtration is one of the best available on the market.
*Disclaimer: Happy Masks are not devices intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease and do not meet the definition of a medical device as set forth in section 201(h) of the FD&C Act.
2. Highly Breathable
The controlled stretching process used to create our nanofiber filter creates millions of micropores per square centimeter, which then enables air to flow more evenly and easily.
Normally, high air flow also means low filtration efficacy. However, the micropore diameter in our filters range in size between 0.1 to 0.5 micrometers, which is wide enough for air to pass freely but still provide effective filtration.
3. Lightweight and Flexible
Most other filters are made out of carbon or a polyester felt material, which need to be a certain thickness to “trap” particles. That means they are heavier and bulkier in comparison. The nanofiber membrane we use is wafer thin, lightweight, and flexible, which makes them significantly more comfortable than other filter materials.
