Disposable respirators protect against airborne particulates. They are made largely from the filtermedia itself and cover the nose, mouth and chin.
It is recommended that they are disposed of at the end of each shift (8 Hours maximum) or sooner if they become heavily contaminated. Selected models within the Starparts range of particulate respirators offer longer protection and filtration performance when used in dusty environments. They can also be reused after an 8 hour shift if the respirator isn’t overly contaminated. These are identified with the letter ‘D’ to reflect compliance with EN 149:2001+A1:2009 clogging test and the letter ‘R’ (after the filtration level) to indicate reusability (NR indicates the respirator is non-reusable).

What is the difference between a FFP1, FFP2 and FFP3 respirator?
FFP (Filtering Face Piece) has a classification related to filtration performance levels and defined per EN149:2001. FFP1 filters out 80% of solid and liquid particles, the FFP2 (94%) and the FFP3 (99%) during test procedure.
What is the nominal protection factor?
Calculated on the basis of Total Inward Leakage (TIL), this number indicates the protection level of the respirator under laboratory conditions. Nominal protection factor of 50 means that the pollution inside the respirator is 50 times lower than the pollution outside the respirator. P1 Respirators have nominal protection of 4, P2 offers protection x 12 and P3 provides 50 times.
What is the assigned protection factor?
The level of respiratory protection that can realistically be expected to be achieved in the workplace by 95% of adequately trained and supervised wearers
using a properly functioning and correctly fitted respiratory protective device.
Why is carbon added?
By adding a layer of activated charcoal to the filter, organic vapours below OEL can be filtered out of the inhaled air. Carbon has a very large surface due to its porous structure, which gives plenty of space to trap nuisance odours passing through the layer.
What does “electrostatic filtermedia” mean and how does it work?
One filtermedia layer of our respirators is electrostatically charged. Due to this charge, fine particles are attracted to the filtermedia and trapped in it. This layer is effectively filtering out fine particles.
How does the exhalation valve work?
Valves have a rubber membrane which closes when inhaling and opens when exhaling. They enable hot and humid exhaled air to be pushed out of the breathing zone in order to keep the face cooler. They also help to reduce resistance which is particularly important for FFP3 respirators, as they have a thicker filtermedia.
