Frequently Asked Questions
The Term FFP means Filtering Face pieces. The numbers proceeding it refers to how much breathable dust, smoke and aqueous fog is filtered. FFP3 offers the greatest protection, followed by FFP2 and finally FFP1. Each has its own Assigned Protection Factor or APF. FFP1 respirators have an APF of 4, FFP2 respirators have an APF of 10 and FFP3 respirators have an APF of 20.
FFP2 & FFP3 Face Masks are European classes of respirators, tested on the direction of inspiration (outside to inside) and take into account leakage to the face and filtration efficiency.
FFP2 face masks meet the guidelines from The World Health Organisation for protection against Covid-19. FFP2 masks have a minimum of 94% filtration percentage and a maximum of 8% leakage to the inside. FFP2 have a typical lifespan of 3-8 hours depending on environmental factors.
FFP3 face masks are the most effective at filtration, with a minimum filtration of 99% and a maximum leakage of 2% to the inside. These masks are better shaped to your face for a more snug fit and typically have a valve to help breathe as the filtration material is much thicker. The valve also reduces the build up of moisture, lengthening the lifespan of the mask. FFP3 masks are typically used for handling asbestos.
FFP2, FFP3, and other respirator masks are effective at protecting the wearer from viral transmission.
Some of our masks have integrated valves. This reduces the moisture level and temperature inside the mask and therefore decreases fogging of spectacles and goggles as well as increasing the wearers' comfort.
A disposable respirator should be worn for no more than eight-hour. In some instances, breathing resistance can become more difficult in which case you should remove the mask – please remember to only do this in a safe environment.
Face Fit Testing helps the wearer to select the respiratory protective equipment that is suitable.
