Important additional information for all types of masks and filters

How can I tell that the filters are spent?

1) If you can still smell something through the gas mask – the product it is meant to protect you from, or a similar product with a strong odour. Tip: for most gas masks, a good test is whether you can smell thinner.

This does not apply to dust masks, of course. They are generally not designed to filter out gases.

2) If breathing through the mask becomes noticeably harder, the filter is too clogged and must be replaced. This applies to both gas masks and dust masks.

3) If the filter or mask starts to become visibly dirty; this often goes hand in hand with harder breathing. 

How do I extend the service life?

1) Unless necessary, avoid using gas masks in dusty environments or as a dust mask, as the gas filter will then clog more quickly.

2) Even when wearing a gas mask, always work with good extraction or good ventilation.

3) After use, store the mask and/or filters in a zip-lock bag, resealable box or similar to prevent dust and reactions with gases.

Using masks and filters

1) Write the date of first use on the bag or box in which the filters and mask are stored. This gives you an indication of how old the filter is and how often it has been used.

2) Only use masks that fit closely around the nose and mouth, so that no false sense of security can arise. Choose the right size and make sure the clips in the mask are pressed firmly into place.
