FFP1
Respirator masks (which means they are made of a fabric designed to filter the air or impurities) are based on a grading system do indicate how much protection they offer. First up is FFP1, which protects against materials in concentrations up to 4x OEL or 4x APF (assigned protection factor). Because it is the first rung on the ladder (so to speak), they are the most affordable option.
FFP3
The masks that offer the highest level of protection are FFP3, which protect against materials in concentrations up to 50x OEL or 20x APF. This is substantially higher than FFP1 and they can block both liquid and solid aerosols.
Current NHS guidelines stipulate FFP3 face masks for virus and bacterial infection control when the contagion is spread through coughing and sneezing. They are also often used by healthcare professionals when handling hazardous pharmaceutical chemicals.
Un-valved
Besides the level of protection that each kind of mask offers, there are also some design elements that you may want to consider.
Un-valved masks mean that the filtration system is built into the fabric, and they can therefore be lightweight and fairly discreet. This can make the mask comfortable to wear as they are non-bulky and don’t feel heavy on the face.
Folded
Another design element that you can choose between is whether you’d prefer a folded or a moulded mask. Folded masks are very discreet and easy to carry around with you and the fabric design is quite breathable.
They offer a close fit to the face because of the elastic head straps, however, they do not offer a perfectly flush fit.

Protection
Our coating is biocompatible (tested under GLP conditions) and is manufactured in Germany under the European Directive 93/42/EC and DIN 13485-2003MPG.

Destroys Bugs
It uses a semi-permanent nano scale layer of silicon dioxide (SiO2).
Within this layer are anti pathogen agents, which are slowly released whilst the surface is in place (up to ten days).

No more nasties
Not only is our coating effective against bacteria but it is also effective against a wide range of pathogens including Hepatitis, Influenza, HIV, Staphylococcus aureus, Psuedomonas auruginosa and Candida albicans.
