The best mask on the market. It offers high protection during visits to hospitals, even in a Covid-19 environment. It is now also exhibited in major museums, with reference to the Covid-19 pandemic. However, it is not suitable for prolonged use. After a few hours of use, it causes intense headaches, at least for me. Also, its price is an issue...

Very high-quality mask that is not meant to be taken off and put back on.

It perfectly covers the nose and mouth and does not move at all during use. I used it in a place where I had to speak for several hours, and the mask did not lift even once from the chin, nor did it fall off the nose. Additionally, I had no issues with breathing, I didn't even notice it.

It is FFP3 and obviously the specification is 100% genuine since it has the guarantee of 3m.

The downside is that, due to the fact that it is held with elastic bands on the head to fit perfectly, if you start taking it off and putting it back on, problems arise. The elastic bands do not withstand much, and the nose cushion can come off.

It is a "single-use" mask for cases where you know you will wear the mask for many hours in a crowded place. I believe that there is no more "secure" protection with a mask.

The mask is for healthcare professionals visiting patients with airborne transmitted diseases. Strictly for single use only. Anything else is a compromise and bad practice. You must know how to put it on and perform a fit test. It is not worn for fun but where there is a genuine need.
