FAQS About The Products

Can disposable medical face masks be sterilized and reused?

No. Disposable medical face masks are intended for a single use only. After use they should be removed using appropriate techniques (i.e. do no touch the front, remove by pulling the elastic ear straps or laces from behind) and disposed of immediately in an infectious waste bin with a lid, followed by hand hygiene.

What types of face mask are there?

There are, of course, many types of face masks including those FFP type mask, kn95, n95 etc, but here we are concerned with medical face masks. Medical face masks have been designed to meet specific standards of performance.

What is a 3 ply mask?

A 3 ply mask is made up of three layers fastened together. In medical masks, these will be made of paper or another non-woven fabric. The outer layer repels particles (including fluids for certain masks e.g. type IIR), the middle layer is the key section that filters out bacteria, the inner layer is soft next to the skin and can absorb small amounts of fluids e.g. spit.

How do FFP2, KN95 and N95 masks compare?

These are standards applied to respirator masks. FFP2 is a European standard, KN95 a Chinese standard and N95 a USA standard. These are approximately equivalent standards but do differ somewhat in specific testing requirements.

What are FFP1, FFP2 and FFP3 masks?

These are different grades of respirator masks in ascending order of protection. FFP stands for Filtering Face Piece. The FFPn classification relates to the categories within the European standard against which the masks are tested.

What does FFP mean?

The abbreviation FFP stands for Filtering Face Piece. It is mainly used to describe respirator style face masks, FFP1, FFP2 and FFP3 under EN149 tests. The higher the number the greater the filtration. FFP2 (N95) >95% and FFP3 (N99) >99%. Sometimes however please say “4 Ply FFP2”, what they really mean is EN14683 Type II which is a three ply face mask with a filtration >95%. The terminology just gets confused.

What is the difference between valved and non-valved?

`The valve is a comfort device. It does not affect or contribute to the level of protection but controls how much and how quickly air can escape from the respirator to reduce the build-up of heat and moisture. If the respirator wearer is ill, the valve will not stop them spreading infection as their breath or cough can enter the air without filtering as the valve opens on exhalation.
