What is a N95 FFP2 Mask (Respirator)?

by Nirvana Being on January 05, 2022

During the coronavirus pandemic, masks have become a key strategy to reduce transmission risk.  While cloth masks were recommended during the first wave, many Countries in Europe now recommend well-fitted N95 FFP2 masks for the highest protection.

Not all masks are the same. Filtering facepiece(FFP) respirators, commonly referred to as N95 masks, are regulated by the National Institute for Occupational Safety and Health.

Here is a breakdown of what an N95 mask is:

N: This is a Respirator Rating Letter Class. It stands for “Non-Oil” meaning that if no oil-based particulates are present, then you can use the mask in the work environment. Other masks ratings are R (resistant to oil for 8 hours) and P (oil proof).

95: Masks ending in a 95, have a 95 percent efficiency. Masks ending in a 99 have a 99 percent efficiency. Masks ending in 100 are 99.97 percent efficient and that is the same as a HEPA quality filter.

.3 microns: The masks filter out contaminants like dusts, mists and fumes. The minimum size of .3 microns of particulates and large droplets won’t pass through the barrier, according to the Centre for Disease Control and Prevention (CDC.). A new class of masks has recently emerged using nanofiber media that has >95% down to 0.1 microns.

FFP2: FFP stands for “filtering face piece”. It is a European standard for mask efficiency - FFP2 masks filter at least 94% of all aerosols, including airborne viruses such as covid-19.


A study published in December by the Max Planck Institute, a German research organisation, found well-fitting FFP2 masks reduced the risk of infection with COVID-19 to 0.1%.


Nirvana Being has been at the forefront on mask science and introduced reusable/washable Airific & Nirvana N95 FFP2 community masks with nanofiber filters back in April, 2020.  In a Country with the worst air pollution and communicable disease record on the planet, we felt strongly about delivering the highest filtration efficacy, to drive safety and well-being.
