Powered Air-Purifying Respirators (PAPRs) are a popular choice for tasks where high respiratory protection and comfort are needed, such as welding fume, grinding dust, pharmaceutical handling, woodworking, and certain painting applications. A question we often receive is whether one PAPR can be shared between multiple workers on different shifts, or across a team.
The practical answer is yes, PAPRs can often be shared, but not “as-is” and not in every situation. Sharing must be controlled through risk assessment, hygiene procedures, correct maintenance, and in many cases allocating certain parts to each individual wearer.
📋 Key Takeaways
- PAPR sharing is usually possible, but only with a clear cleaning, inspection, and record-keeping process between users.
- Anything that contacts the face, head, hair, or breathing zone should be treated as personal issue wherever possible (hoods, faceseals, headliners, sweatbands).
- Filters are not “personal” but they are consumables, and change schedules must be managed so protection is not compromised.
- Some work (for example asbestos removal) may require specific RPE controls and decontamination standards, sharing may be inappropriate or restricted.
- Your decision should be based on a site-specific risk assessment aligned with UK RPE guidance such as HSE HSG53.
What “sharing a PAPR” actually means
A complete PAPR system typically includes:
- A blower/turbo unit (motor, battery, alarm/indicator)
- Filters (particulate and/or gas-vapour)
- A breathing tube
- A headtop (hood, helmet, faceshield) with a faceseal/shroud
- Belts/harnesses
- Optional covers and accessories
When people talk about sharing, they may mean:
- Sharing the whole kit, including the hood or helmet, or
- Sharing only the blower unit, while each worker has their own headtop and “skin-contact” parts
Option 2 is usually the safer and more realistic approach.
UK compliance basics, what employers must ensure
In the UK, employers must ensure RPE is:
- Adequate and suitable for the hazard and task (under COSHH where applicable)
- Compatible with other PPE
- Maintained, inspected, and used correctly
- Supported by information, instruction, and training
HSE’s guidance document HSG53 (Respiratory protective equipment at work) is widely used as the go-to reference for selecting, using, and maintaining RPE in UK workplaces. It strongly emphasises correct selection, maintenance, and preventing contamination and cross-infection where relevant.
The real issue with sharing, hygiene and cross-contamination
PAPR headtops and breathing air paths can become contaminated by:
- Sweat, hair products, and skin oils
- Dusts and fumes settling on the headtop or inside shrouds
- Biological contamination (for example when workers are ill, or where there is infection control concern)
- Hazardous substances that require controlled decontamination
Sharing is not just a comfort issue, it can become a health and compliance risk if you cannot reliably clean and disinfect the components.
Never share a PAPR between workers if you cannot verify it has been cleaned, disinfected (when required), inspected, and reassembled correctly. A poorly cleaned headtop, a damaged faceseal, or an incorrectly fitted filter can reduce protection and may expose the next wearer.
What parts can be shared vs what should be personal issue?
A sensible rule is: if it touches the user’s head/face/hair or sits inside their breathing zone, treat it as personal issue whenever you can.
Practical sharing guide (typical best practice)
| Component | Shareable? | Why |
|---|---|---|
| Blower/turbo unit | Usually yes | Easier to wipe down and does not contact face directly |
| Battery + charger | Usually yes | External component, simple cleaning |
| Filters | Sometimes | Consumable, but change control is essential, never reuse if contaminated or soaked |
| Breathing tube | Sometimes | Can be shared if manufacturer cleaning allows, often better to allocate per user |
| Belt/harness | Sometimes | Can be wiped, but sweat contamination is common |
| Hood / inner shroud | Prefer personal issue | High contact area, difficult to fully decontaminate in busy sites |
| Faceseal (faceshield/helmet) | Prefer personal issue | Seal integrity and hygiene concerns |
| Sweatbands/comfort pads | Personal issue | Direct absorbent contact, high hygiene risk |
Always check the specific manufacturer instructions for your exact PAPR, because cleaning methods and what can be disinfected safely vary by model and material.
When sharing is more likely to be acceptable
Sharing tends to work well when:
- You share the blower unit, but issue separate hoods/headtops per worker
- The environment is dry dust (not sticky resins, oils, heavy overspray)
- You have a defined cleaning station
- You have spare consumables (prefilters, visor covers, etc.)
- You can perform a documented pre-use check every time
Benefits
- Lower capital cost per worker (share the expensive blower unit)
- Better utilisation across shifts
- Easier stock control if the site standardises one PAPR platform
When sharing may be a bad idea (or needs tighter controls)
Sharing may be unsuitable if:
- Work involves highly hazardous substances requiring strict decontamination controls (task-dependent)
- The headtop is hard to clean thoroughly between users
- Workers have different head sizes, comfort needs, or PPE compatibility requirements
- There is a heightened concern about cross-infection
- The PAPR is used in a way that contaminates the headtop heavily (for example heavy spray applications without protective covers)
If your use involves regulated high-risk removal work (for example asbestos), ensure you follow your industry method statements and RPE requirements. Specialist “asbestos” PAPR and supplied-air solutions often have additional controls that can make casual sharing inappropriate.
A safe, repeatable process for sharing PAPRs on site
1) Assign what is personal vs communal
A common, workable setup:
- Communal: blower unit, battery, charger
- Personal issue: hood/headtop and comfort items (and sometimes breathing tube)
Label personal items with the worker’s name or ID.
2) Clean and disinfect between users (as required)
Follow the manufacturer guidance, then build a simple standard operating procedure:
- Remove filters if required for cleaning steps
- Wipe external surfaces
- Clean headtop parts carefully (especially seals and inner shrouds)
- Allow to dry fully before re-use or storage
3) Inspect before every use
At minimum:
- Check filter is correct type and in date/within change schedule
- Check battery charge
- Check airflow indicator/alarm function where applicable
- Check breathing tube for splits and secure connections
- Check faceseal/shroud for damage and correct fit
4) Store it properly to prevent re-contamination
Once cleaned, the fastest way to ruin good practice is leaving kit on a dusty bench or in a vehicle footwell.

Frequently asked questions
Can two workers share the same PAPR on different shifts?
Yes, in many workplaces this is common, but it should be supported by:
- a cleaning procedure between users
- a pre-use inspection routine
- defined rules on which parts are personal issue
- filter change control and maintenance records
Do PAPRs need face fit testing?
Many PAPR hoods and loose-fitting headtops do not require face fit testing, because they do not rely on a tight seal to the face in the way that tight-fitting half masks and full-face masks do. However, you still need correct size, correct donning, and compatibility with other PPE. Always confirm your headtop type and the required program controls.
Should each worker have their own filters?
Filters are usually managed as consumables rather than personal issue, but you must control:
- correct filter type for the hazard
- exposure and service life
- contamination risk
- storage between uses
In some settings, allocating filters per user can simplify control, but it depends on task and policy.
Bottom line
A PAPR can often be shared between workers, but the safest and most practical method is usually to share the blower unit while allocating individual hoods or headtops to each worker. This reduces cross-contamination risks, improves wearer acceptance, and makes compliance easier.
