Important Additional Information for All Types of Masks and Filters
How do I know when the filters are used up?
If you can smell the product you need protection from, or a similar strong-smelling product, through the gas mask. Tip: For most gas masks, you can test this by trying to smell thinner. This does not apply to dust masks, as they are generally not designed to filter gases.
If breathing through the mask becomes noticeably harder, the filter is too clogged and needs to be replaced. This applies to both gas masks and dust masks.
If the filter or mask becomes visibly dirty, this often coincides with more difficult breathing.
How to extend the lifespan
Try not to use gas masks in dusty environments or as dust masks unless necessary, as the gas filter will clog faster.
Even when using a gas mask, continue to work with good extraction or ventilation.
Store the mask and/or filters in a ziplock bag, grip bag, resealable box, etc., after use to prevent dust and reactions with gases.
Use of masks and filters
Write the date of first use on the bag or box where the filters and mask are stored. This gives you an indication of how old/ how often the filter has been used.
Use only masks that fit well over the nose and mouth to prevent a false sense of security. Choose the right size and make sure the clip over the nose is pressed tightly against the skin.
