MSA COMFO COMBINATION FILTER A1 B2 E1 K1 P3 93 MSA ABEK P3

The MSA Combination Filter 93 ABEK-CO-NO-Hg-P3 RD is suitable as a thread filter for the 400 series half mask and offers protection against the following substances:

• • Carbon monoxide (CO)
  • Organic gases and vapors (A)
  • Inorganic gases and vapors such as chlorine etc. (B)
  • Sulfur dioxide acid gases and vapors (E)
  • < li>Ammonia and organic ammonia derivatives (K)

• Nitrogen oxides (NO)
• Mercury vapors and particles (Hg/St)

The MSA COMFO Combination Filter A1 B2 E1 K1 P3 (93) is a versatile, multi-purpose gas and particulate filter designed for use with MSA’s Comfo series respirators (like the Comfo Classic, Comfo Twin, etc.). It is a “combination” filter because it provides protection against a wide range of hazardous substances, including:

• Various gases and vapors (as indicated by the A1, B2, E1, K1 codes).

• Solid and liquid particles, aerosols, and fumes (as indicated by the P3 code).

The “93” refers to its efficiency class (P3 93%), which is specific to the Korean KOSHA standard.

Detailed Breakdown of the Filter Codes

This filter’s name is essentially a summary of its certifications and capabilities.

1. COMFO:

   • This indicates the filter is designed to be compatible with MSA’s Comfo series of respiratory facepieces and powered air-purifying respirators (PAPRs).

2. Combination Filter:

   • It combines filtration media for both particulates and gas/vapor removal in a single unit.

3. A1 B2 E1 K1: Gas & Vapor Protection (EN 14387 Standard)

   • A1: Protection against certain organic gases and vapors with a boiling point >65°C (e.g., solvents, benzene, toluene). The “1” indicates a low capacity/loading.

   • B2: Protection against inorganic gases and vapors (e.g., chlorine, hydrogen sulfide, hydrogen cyanide). The “2” indicates a medium capacity/loading.

   • E1: Protection against sulfur dioxide and other acidic gases. The “1” indicates a low capacity/loading.

   • K1: Protection against ammonia and organic ammonia derivatives. The “1” indicates a low capacity/loading.

4. P3: Particulate Protection (EN 14387 Standard)

   • P3 is the highest level of particulate filtration for a gas mask filter.

   • It is at least 99.95% efficient at filtering solid and liquid particles, including toxic dusts, mists, fumes, and aerosols (e.g., asbestos, heavy metal dust, biological agents).

5. 93:

   • This refers to the KOSHA (Korean Occupational Safety and Health Agency) P3 classification.

   • In the KOSHA standard, a “P3 93%” filter is at least 99.9% efficient. This is slightly different from the European EN143 standard for P3, but still indicates a very high level of protection against particulates.

6. MSA ABEK P3:

   • This is a simplified, generic name for this type of filter. An “ABEK P3” filter is known in the industry as the most comprehensive combination filter, offering a broad spectrum of protection against the gas/vapor classes A, B, E, K and particulates (P3).

Key Features & Benefits

• Broad-Spectrum Protection: A single filter protects against a wide array of hazards, making it suitable for complex or unpredictable environments.

• High-Efficiency Particulate Filtration: The P3 rating ensures protection against the most hazardous fine particulates.

• MSA Quality: Built to MSA’s high standards for reliability and performance.

• Compatibility: Designed to work seamlessly with MSA Comfo respirators, ensuring a secure and safe connection.

Typical Applications

This filter is used in industries where workers may be exposed to multiple types of airborne hazards simultaneously. Examples include:

• Chemical Industry

• Pharmaceutical Manufacturing

• Emergency Response & HAZMAT

• Laboratories

• Metal Processing & Welding (where gases and metal fumes are present)

• Water & Wastewater Treatment

• Asbestos & Hazardous Material Abatement
