OUR TECHNOLOGY

Happy Masks block airborne particles down to 0.3 micros while still permitting airflow. This image shows the filtration process and direction of airflow

How does it work?

How does
it work?

Our wafer-thin nanofiber membrane filter is made of fibers 1/500th the width of a human hair, which form an ultra-fine, web-like mechanical barrier that physically blocks airborne particles.

Our filters are tested to block >95% of particles down to 0.3µm.
To put this into context, here are the sizes of common airborne particles.

Rigorously Tested
with Accredited Labs

Our filtration testing is conducted at labs accredited by the American Association for Laboratory Accreditation (A2LA) to the ISO/IEC 17025 standard. Results have been further validated in independent testing sponsored by the New York Times Wirecutter.

Washable and Reusable

Filters maintain 95%
filtration efficacy after
50 hand-washes.*

The Ultra Series is machine-
washable on gentle cycle in
a mesh bag.

Please follow washing
instructions HERE and allow
masks to air-dry.

*Based on testing conducted at ICS Laboratories. Masks were hand-washed at 100 degrees F for 10 minutes with Tide Free and Gentle detergent.

Repeated Wash Test Report

Breathability

The controlled stretching process used to create our filter creates millions of micropores per square centimeter, ranging in size from 0.1 - .5 micrometers.

The size of the micropores
is wide enough to allow air
to pass freely while still
providing effective filtration.

When worn and cared for correctly, our masks offer one of the highest standards of filtration efficacy without compromising on breathability and comfort.

Type of Masks	HAPPY MASKS	Fabric Mask w/o Filter	KN95 Mask
Filter Material	Nanofiber Membrane	None	Meltblown
Filtration of Aerosols	95%-99%	30%	95%-99%
Filtration Type	Employs mechanical filtration, where an ultra- fine, web-like mechanical barrier physically blocks airborne particles.	None	Utilizes electrostatic charge, where electrical field gradients attract and intercept airborne particles.
Washability/ Reusability	Maintains 95% filtration efficacy after 50 hand washes. Lasts approximately 2 months with normal use.	Washable, multi-use.	Not washable, single-use Filtration declines dramatically if filter gets wet due to dependency on electrostatic charge.
Breathability	Millions of micropores per square centimeter allow air to pass through while still maintaining a high level of filtration.	Varies depending on fabric.	Higher humidity levels, breath resistance, and accumulation of heat.
