Respirator Masks (4,124 offers*)

The length of time you can wear your respirator mask at work depends on many different factors: your exact job, the environment, your work duration, your working conditions, the specific type of mask and your breathing resistance.

Occupational health doctors can usually give you accurate information about the wearing time limits for your job. In general, you should never work with a respirator mask for more than 120 minutes. If you notice that your breathing resistance is too high, you should urgently take a break.

Respirator masks last differently depending on their type, protection class, environment and use. Fine dust masks with particle filters usually last longer than masks with gas filters. Generally, many masks are designed to protect you for only one work shift. That means you only wear them once and then throw them away.

With respirator filters, you can tell if you can only use the filter once or more by a label. The letters NR mean that you should only use the mask for one shift. Filters with the letter R can also be used more often, but only under certain circumstances.

Respirator masks are usually equipped with particle or gas filters. Activated carbon is often used for the gas filters. The activated carbon also functions as a filter, a so-called activated carbon filter. This is used because activated carbon manages to absorb gases and vapours in the environment.

For sanding metal and wood, an FFP 2 mask is usually suitable, but this depends on the material being worked on. If it is hard wood or high-alloy steel, you are better protected with an FFP 3 mask. For painting, you should also choose at least an FFP 2 mask, depending on how regularly you work and what kind of paints you use.

You can divide respiratory protection masks into three so-called FFP protection classes. An FFP 1 mask protects against non-toxic and non-fibrogenic dusts. The FFP 2 mask is used for harmful dusts and also smoke, while masks with FFP 3 protect against toxic, carcinogenic and radioactive substances.

If you are trying to remove mould, you should definitely choose a mask with protection class FFP 3. Here you can be sure that you will not inhale dangerous mould spores. When working with asbestos, you can also use FFP 3 masks, but only if the asbestos concentration is not too high and you do not work for too long. You are better protected here with an insulating full-face mask.
