The last two types(II & IIR) are used in hospital and in Labs.
Edit
I made a search to find more information about these type of mask
Here is what it says about Type II
(Translated from Danish)
Face mask type 2 reduces the risk of infection both ways; both from the wearer and to the wearer. This type is used by healthcare professionals in contact with people with covid-19 and people who are suspected of being infected with covid-19.
The mask has a protective 3-layer filter with the following properties:
1. Waterproof layer that absorbs dust, odors and particles
2. Barrier layer that blocks bacteria
3. Soft inner layer that is comfortable against the skin
Type IIR:
This type also reduces the risk of infection both ways; both from the wearer and to the wearer. These face mask is used by surgical teams as they protect against blood and body fluids. "R" stands for splash resistant.
You can use type IIR face mask in the public space - e.g. when going by public transport. The mask is for single use only and you should therefore replace it after use or if it gets wet or dirty.
