Pack of 10. Dust filter is a basic thin filter mask that protects against spray dust and particles, but not spray vapors and propellant.
Dust filters are disposable items, which according to the standard are usually counted on about 8 hours of active use. This means you can reuse them in batches for shorter periods of use, as long as you take good care of the filter and store it in a sealed bag when not in use. However, if you are looking for 100% protection for a longer period of time, we recommend you check out our gas masks with active carbon filters.
