📋 Key Takeaways
- Clean your respirator after each shift, and always before it’s shared, to reduce contamination and extend service life.
- Remove filters and cartridges before washing, most are not designed to be washed or submerged.
- Use mild detergent and warm water for routine cleaning, then use a manufacturer-approved disinfectant if required by your workplace risk assessment.
- Dry fully and store in a clean, sealed container or bag to prevent re-contamination and deformation of the face seal.
Reusable respirators are built for repeated use, but only if they’re cleaned correctly. Poor cleaning can damage valves and seals, shorten the life of the respirator, and in some cases reduce protection because residue, dirt, or disinfectant can affect the fit.
This guide covers a safe, practical cleaning routine for the most common reusable RPE types:
- Half-face reusable respirators
- Full-face reusable respirators
- Powered respirators (PAPR) headtops, hoses, and belts
Always follow the specific manufacturer instructions for your exact model, especially for disassembly and which disinfectants are permitted.
- Do not wash or soak particulate filters, gas/vapour cartridges, or combination filters unless the manufacturer explicitly states they are washable. Most are not, and water can ruin them.
- Do not use strong solvents, petrol-based cleaners, or aggressive sprays on face seals or visors, these can cause swelling, cracking, fogging, and poor fit.
- If the respirator was used for high-hazard contaminants (for example asbestos work), follow your site’s controlled decontamination procedure. Routine “sink cleaning” may be inappropriate.
What you need before you start
✅ Benefits
✅ A correct cleaning routine helps you:
- Maintain a reliable face seal and consistent fit
- Reduce skin irritation from dirt and sweat build-up
- Keep exhalation and inhalation valves working properly
- Improve comfort and hygiene, especially for daily wear
- Extend the life of the mask body and head harness
Recommended basics:
- Disposable nitrile gloves (to prevent contaminating cleaned parts)
- Mild detergent (non-perfumed is ideal)
- Warm water (not hot)
- Soft brush or cloth (non-abrasive)
- Clean, lint-free towel or drying rack
- A clean container or bag for storage
If you are cleaning masks frequently in a workshop, dedicated respirator cleaning wipes are useful for quick face-seal wipe-downs between tasks, but they do not replace a proper wash when the mask is visibly dirty or heavily used.
Step-by-step: Cleaning a half-face or full-face reusable respirator
1) Prepare a clean area
Choose a sink or cleaning station away from dust-generating work. Wash your hands and put on gloves.
2) Remove filters and cartridges (do this first)
- Twist off bayonet filters or unscrew thread filters.
- Set them aside somewhere clean and dry.
Tip: If your filters are near end-of-life, this is a good time to replace them rather than refit them.
3) Disassemble the respirator as the manufacturer allows
Typical removable parts include:
- Head harness or straps
- Speech diaphragm cover (some models)
- Nose cup (some full-face masks)
- Inhalation/exhalation valves (model dependent)
Do not force parts. If you are unsure, stop and check your user instructions.
4) Wash with mild detergent and warm water
- Use warm water and mild detergent to clean the mask body, face seal area, and straps.
- Use a soft brush for crevices around valve seats and fittings.
- For full-face masks, clean the visor with a soft cloth to avoid scratches.
5) Rinse thoroughly
Rinse until all soap residue is gone. Residue can irritate skin and may affect the seal.
6) Disinfect if required
Whether you disinfect depends on your workplace hygiene rules and risk assessment (for example shared masks, biological exposure, healthcare environments).
Use only a manufacturer-approved disinfectant method. Commonly approved options (model dependent) include certain quaternary ammonium solutions or diluted hypochlorite solutions at controlled strength and contact time.
7) Dry fully
- Air dry in a clean area, out of direct heat and sunlight.
- Avoid radiators, heat guns, and direct high heat, these can warp seals.
8) Reassemble and function-check
Once dry:
- Refit valves correctly (if removed)
- Refit straps/harness
- Reattach filters or new filters
Then perform:
- Negative pressure seal check (cover inlets and inhale gently)
- Positive pressure seal check (cover exhalation outlet where applicable and exhale gently)
9) Store correctly
Store clean respirators:
- In a sealed, clean bag or case
- Away from dust, sunlight, chemicals, and deformation
Cleaning PAPRs (Powered Air Respirators): headtops, breathing tubes, belts, and filter covers
PAPR systems vary by brand, but the cleaning principles are consistent:
What you can usually clean
- Headtop shell and visor (external)
- Face seal or shroud (as permitted)
- Breathing tube outer surface
- Belt and harness components
- Turbo unit exterior (usually wipe-clean only)
What you should not wash
- Filter elements (unless specifically designed as washable)
- Electronics, batteries, chargers
- Turbo units beyond the permitted wipe-down method
Best practice for PAPRs
- Use wipe-down cleaning after each shift, especially on the face seal contact points.
- Consider protective covers (where available) to reduce contamination and make cleaning faster.
- Store PAPRs in a dedicated case/backpack so the headtop and seals are not crushed.
How often should you clean a reusable respirator?
A sensible baseline:
- After each day/shift of use
- Immediately if contaminated, visibly dirty, or used in a shared environment
- Before fit testing, and before switching filter types
If multiple people share equipment, cleaning and disinfection should happen between users, and you should follow your company RPE programme.
Common mistakes that reduce protection
- Cleaning the mask while filters are still attached
- Using alcohol wipes or harsh sprays that dry out or degrade seals (unless manufacturer-approved)
- Reassembling while damp, which can encourage odours and microbial growth
- Storing masks loose in toolboxes where seals get distorted
- Ignoring valve condition, a curled or dirty valve can cause leakage
