When working in environments with hazardous gases, vapors, or particles, your safety depends on one crucial detail: the right filter.
Dräger, a global leader in safety technology, offers a wide range of gas and combination filters that ensure reliable respiratory protection in the most demanding conditions.

Code	Color	Protects Against
A	Brown	Organic gases and vapors (e.g., solvents, paints)
B	Grey	Inorganic gases and vapors (e.g., chlorine, hydrogen sulfide)
E	Yellow	Acid gases (e.g., sulfur dioxide, hydrogen chloride)
K	Green	Ammonia and amine derivatives
P	White	Particulates, dust, mists, and fumes

For example, the Dräger A2B2E2K2-P3 R D filter offers comprehensive protection against organic, inorganic, acidic gases, ammonia, and particulates — making it a preferred choice for industrial, chemical, and maintenance applications.

Dräger filters are available in two main connection types:

• Bayonet filters – designed for half and full-face masks like Dräger X-plore® 3300 / 3500 / 5500.

• RD40 filters – with standard 40 mm threaded connectors, suitable for Dräger X-plore® 6300 / 6570 / 7000 and similar professional respirators.

Always check your mask model before choosing a filter to ensure a perfect seal and optimal protection.

Shelf Life and Storage

Dräger filters typically have a shelf life of 5 years (unopened, stored properly).
Keep them in a cool, dry, sealed package, away from direct sunlight and chemicals.
Once opened or used, filters should be replaced according to the manufacturer’s recommendations or whenever breathing resistance increases.

When to Replace a Filter

You should replace your filter immediately if:

• You notice increased breathing resistance

• You detect smells or tastes of chemicals through the mask

• The filter is damaged, wet, or contaminated

• It has exceeded the recommended usage time

Using an expired or saturated filter can compromise safety — always inspect before use.

Expert Recommendation

For multi-purpose industrial use, we recommend:

• Dräger 6738804 A2B2E2K2 RD40 Filter – for full-face masks

• Dräger 9405 A1B1E1K1-P3 Bayonet Filter – for half masks

These filters meet EN 14387 and EN 143 standards, ensuring maximum reliability for gas and particle protection.
