Respiratory protection is essential in workplaces where employees may be exposed to hazardous gases, vapors, dust, fumes, and airborne particles.
Unlike disposable masks, full face respirators provide both respiratory and eye protection by covering the entire face.
The EN 136 mask standard defines the requirements for full face masks used with replaceable filters and respiratory protection systems.
This guide explains:
- What EN 136 is
- The structure of a full face mask
- Filter compatibility
- Industrial applications of EN 136 full face respirators
What Is EN 136?
EN 136 is a European standard that specifies the minimum requirements, testing methods, and performance requirements for full face masks used in respiratory protective devices.
A full face mask certified according to EN 136 must provide protection for:
- Respiratory system
- Eyes
- Face
EN 136 applies to reusable full face respirators that work together with suitable:
- Particle filters
- Gas filters
- Combined filters
- Powered or supplied air systems (depending on design)
Why Is EN 136 Important?
Different workplace hazards require different levels of respiratory protection.
A simple dust mask may protect against particles, but it cannot protect against:
- Toxic gases
- Chemical vapors
- Certain industrial contaminants
A certified EN 136 full face respirator helps ensure:
✓ Proper face coverage
✓ Reliable sealing performance
✓ Compatibility with approved filters
✓ Protection against specific workplace hazards
Full Face Mask Structure
A full face respirator consists of several key components that work together to provide protection.
1. Face Seal
The face seal creates a secure connection between the mask and the user’s face.
Functions:
- Prevent contaminated air leakage
- Improve protection efficiency
- Maintain comfortable wearing experience
Important factors:
- Correct size
- Proper fitting
- Facial hair considerations
A poor seal can significantly reduce respiratory protection.
2. Panoramic Lens
The large viewing lens provides:
- Wide field of vision
- Eye protection
- Better workplace awareness
Common lens materials:
- Polycarbonate
- Impact-resistant materials
Applications requiring clear vision:
- Chemical handling
- Industrial maintenance
- Emergency response
3. Filter Connection System
The filter connection allows the mask to work with different respiratory filters.
Common connection types:
EN 148-1 Thread Connection
Many industrial full face respirators use the standard:
EN 148-1 Rd40 thread connection
Advantages:
- Wide filter availability
- Suitable for industrial applications
- Easy filter replacement
4. Inhalation and Exhalation Valves
Valves control airflow inside the respirator.
Functions:
Inhalation Valve
Allows clean filtered air to enter.
Exhalation Valve
Allows exhaled air and moisture to leave.
Benefits:
- Reduced breathing resistance
- Improved comfort
- Less fogging
5. Head Harness
The head harness keeps the respirator securely positioned.
Features:
- Adjustable straps
- Stable fit
- Even pressure distribution
A proper fit is essential for effective protection.
Filter Compatibility for EN 136 Full Face Respirators
One of the biggest advantages of full face respirators is the ability to use replaceable filters.
Different filters protect against different hazards.
1. Particle Filters
Particle filters protect against:
- Dust
- Mist
- Smoke particles
- Aerosols
Common classifications:
- P1
- P2
- P3
Example:
P3 filters provide a higher level of particle filtration than P1 and P2.
Applications:
- Grinding
- Welding
- Construction dust
- Pharmaceutical production
2. Gas and Vapor Filters
Gas filters protect against chemical gases and vapors.
Common filter types:
| Filter Type | Protection |
|---|---|
| A | Organic gases and vapors |
| B | Inorganic gases |
| E | Acid gases |
| K | Ammonia and derivatives |
3. Combined Filters
Combined filters provide protection against both:
- Particles
- Gases or vapors
Example:
ABEK-P3 filter
Protection against:
- Multiple gas types
- Chemical vapors
- Particulates
Common applications:
- Chemical processing
- Industrial cleaning
- Emergency response

EN 136 Full Face Mask vs Half Mask Respirator
| Feature | Full Face Mask | Half Mask Respirator |
|---|---|---|
| Face coverage | Full face | Nose and mouth only |
| Eye protection | Yes | No |
| Protection level | Higher | Moderate |
| Comfort | More coverage | Lighter |
| Suitable for chemicals | Yes | Depends on hazards |
A full face respirator is preferred when workers need both respiratory and eye protection.
How to Choose an EN 136 Full Face Respirator?
Before selecting a full face mask, consider:
1. Identify the Hazard
Determine whether workers face:
- Dust
- Gas
- Vapor
- Chemical exposure
- Mixed hazards
2. Select the Correct Filter
The filter must match the hazard.
Examples:
Dust:
→ P2 / P3 particle filter
Organic vapor:
→ A-type gas filter
Multiple chemical hazards:
→ ABEK-P3 combined filter
3. Check Standards and Certification
Ensure the product complies with:
- EN 136 – Full face masks
- EN 143 – Particle filters
- EN 14387 – Gas and combined filters
