Choosing the appropriate Powered Air Purifying Respirator (PAPR) is essential for ensuring compliance with UK health and safety legislation and providing effective and comfortable respiratory protection for your workforce


This guide outlines the key factors to consider when selecting a PAPR for your specific work environment.

1. Identify the Type of Hazard
Begin by assessing the specific airborne hazards present in your workplace:
• Particulate hazards: Dust, mists, and biological agents such as bacteria and viruses.
• Gas and vapour hazards: Organic vapours, acid gases, ammonia, etc.
• Combination hazards: Require multi-purpose filters that protect against both particulates and gases.
Ensure the selected PAPR is compatible with certified filters or cartridges for the identified hazard types and complies with relevant standards such as EN 12941 or EN 12942.

2. Determine the Required Assigned Protection Factor (APF)
The APF indicates the level of protection a PAPR provides. Match the required APF to the results of your workplace risk assessment:
• Loose-fitting hoods or helmets: APF of 25 – suitable for moderate risk levels.
• Tight-fitting full-face PAPRs: APF up to 1000 – ideal for high-risk environments.
Refer to UK HSE guidelines when creating your Risk Assessment and selecting PAPR to ensure the selected APF meets legal and safety requirements.

3. Choose the Appropriate Facepiece or Hood Type
Select a design that suits the wearer and task:
• Loose-fitting hoods/helmets: No fit testing required; ideal for wearers with facial hair or glasses. Can also offer greater protection against contamination to head and shoulders from chemicals and airborne hazards
• Tight-fitting facepieces: Require fit testing but generally offer higher protection.
• Full-face vs. half-face: Full-face provides eye protection; half-face may be lighter and more comfortable for extended use.

4. Prioritise Comfort and Ergonomics
Comfort is critical for prolonged use and user acceptance. Consider:
• Weight and balance of the blower unit.
• Motor noise levels.
• Mounting options – belt, backpack or fully head mounted
• Cooling airflow features to reduce heat stress in warm environments.

5. Evaluate Intrinsic Safety, Battery Life and Charging Needs
Match intrinsic safety and battery performance to requirements:
• Battery run times typically range from 4 to 12 hours.
• Look for swappable rechargeable battery options, or fast recharging solutions for demanding environments.
• For explosive or flammable environments, choose intrinsically safe systems.

6. Factor in Maintenance and Total Cost of Ownership
Ongoing maintenance impacts both safety and budget:
• Frequency and cost of filter and cartridge replacement.
• Battery replacement and spare parts availability.
• Cleaning and disinfection processes, especially for shared units.
• For demanding environments consider outsourced maintenance for a continually compliant fleet, such as a Total Care Programme

7. Verify Regulatory Compliance
Ensure the selected PAPR meets all applicable standards:
• Certified under UK or European regulations (e.g., CE marked, EN 12941/12942).
• Compliant with your organisation’s respiratory protection program and HSE requirements.

8. Check Compatibility with Other Personal Protective Equipment (PPE)
The PAPR must integrate effectively with existing PPE:
• Confirm compatibility with hard hats, safety goggles, hearing protection, and protective clothing.
• Consider integrated systems that reduce bulk and improve ease of use - many headtops will integrate much of the above PPE

9. Consider Environmental and Work Conditions
Select a system suitable for your workplace environment:
• Performance in high humidity, extreme temperatures, or confined spaces.
• Noise levels (important if auditory alarms are used) – consider integration of radios if required
• Mobility – heavier units may limit freedom of movement.

10. Ensure User Training and Acceptance
User engagement is key to compliance:
• Choose models that are intuitive to operate and easy to don/doff.
• Ensure clear indicator systems (e.g., for low battery or filter clogging).
• Involve workers in the selection process to boost comfort, confidence, and proper usage.
• Ensure training programme is delivered professionally and demonstrates clear improvements in the investment

Selecting the right PAPR involves more than just meeting technical specifications — it’s about ensuring protection, compliance, and usability in real-world conditions. By systematically considering the factors above, you can implement a respiratory protection solution that safeguards your workforce and meets the highest standards of safety and comfort.
