A Powered Air Purifying Respirator (PAPR) is a significant investment in worker safety. But like any precision equipment, it requires regular cleaning and maintenance to function properly.

Neglecting PAPR maintenance leads to:

  • Reduced airflow and protection

  • Premature component failure

  • Battery performance degradation

  • Cross-contamination between users

  • Costly replacements

At Junsee Group, we believe that proper maintenance is not optional—it is essential. This guide provides daily cleaning and maintenance steps to keep your PAPR systems operating safely and efficiently.



Before You Start: Critical Safety Warnings

WarningWhy It Matters
Never submerge the blower unit, battery, or filters in liquidWater ingress damages internal components and creates electrical hazards 
Do not use gasoline, organic solvents, or chlorinated degreasing fluidsThese chemicals degrade plastics and rubbers, destroying critical seals 
Ensure no liquid enters the breathing tube or filterContaminated air passages can expose workers to hazards 
Always clean in a safe, uncontaminated areaCleaning in contaminated areas transfers hazards to equipment 
Follow manufacturer-specific instructionsDifferent PAPR models have different approved cleaning agents 

Junsee Group recommendation: Before cleaning any PAPR, consult the manufacturer's user manual for model-specific instructions and approved cleaning agents.


What You Will Need

ItemPurpose
Mild soap and warm waterGeneral cleaning 
Lint-free cloths or soft spongesWiping components without scratching 
Manufacturer-approved disinfectant wipesDisinfection between users 
Soft-bristle brush (optional)Loosening stubborn dirt

Approved Cleaning Agents

The following agents have been tested for PAPR cleaning :

Cleaning AgentType
Mild dishwashing liquid soapGeneral cleaning
70% IPA (Isopropyl Alcohol)Disinfection
10% bleach solution (diluted)Disinfection (with rinse)
Sani-cloth HB wipesDisinfection
SaniWipesDisinfection

Note: Bleach-containing wipes should only be used when necessary (e.g., after exposure to infectious patients), as bleach may cause premature damage. If used, rinse with a water-moistened wipe afterward .


Step-by-Step Daily PAPR Cleaning Procedure

Step 1: Exit to a Safe, Uncontaminated Area

Before removing or cleaning any PAPR component:

  1. Exit the contaminated work area while still wearing the PAPR

  2. Move to a designated clean area (e.g., equipment decontamination zone)

  3. Do not remove the PAPR while still in the hazard zone 

⚠️ Critical: Never remove or clean PAPR components in an area where contaminants can contact or accumulate inside the equipment .

Step 2: Perform Hand Hygiene and Don Clean Gloves

  1. Wash hands thoroughly or use alcohol-based hand sanitizer

  2. Don clean disposable gloves before handling used PAPR components 

  3. This prevents cross-contamination from your hands to the equipment

Step 3: Remove and Clean the Hood or Helmet

This is the component with the most direct contaminant exposure.

Sub-stepAction
3.1Remove the hood/helmet from the breathing tube connection
3.2Inspect for tears, holes, or visible damage. Replace if damaged 
3.3Wipe all outer surfaces with a manufacturer-approved disinfectant wipe 
3.4For heavy soil, use a soft cloth moistened with mild soap and warm water 
3.5Ensure disinfectant remains wet for the required contact time (check product label) 
3.6Wipe the headgear suspension and straps similarly
3.7Allow the hood to air dry upright on a clean surface 

For hoods with visors: Clean the protective face shield with a soft cloth and approved cleaner. Do not use abrasive materials that could scratch the visor .

Step 4: Clean the Breathing Tube

Sub-stepAction
4.1Detach the breathing tube from both the blower unit and the hood
4.2Clean the outside of the tube with mild soap solution and a lint-free cloth 
4.3Do not allow liquid to enter the inside of the tube 
4.4Rinse with clean water (outside only) 
4.5Wipe dry or allow to air dry completely

⚠️ Critical: If liquid enters the breathing tube, it must be thoroughly cleaned and dried before reuse. Contaminated air passages compromise respiratory protection .

Step 5: Clean the Blower Unit (Motor Assembly)

Sub-stepAction
5.1Ensure the blower unit is turned off
5.2Do not remove the filter during cleaning—it prevents contaminants from entering the blower 
5.3Wipe the exterior of the blower with a lint-free cloth moistened with mild soap solution 
5.4Take care to avoid getting liquid near the air inlet or battery connector terminals 
5.5Dry with a clean, lint-free cloth

Important: Never submerge the blower unit in water or any cleaning fluid .

Step 6: Clean the Battery Pack

Sub-stepAction
6.1Remove the battery from the blower unit (if detachable)
6.2Wipe the exterior with a mild soap solution and lint-free cloth 
6.3Avoid getting cleaning solutions or water on the battery connector contacts or gasket 
6.4Dry thoroughly before reconnecting

For healthcare settings: If bleach wipes are used on the battery pack or blower, rinse with a water-moistened wipe afterward to prevent premature damage .

Step 7: Clean the Belt or Harness (If Applicable)

Sub-stepAction
7.1Remove the belt/harness from the blower unit
7.2Clean with mild soap solution and a soft-bristle brush if needed 
7.3Rinse with clean water
7.4Air dry completely before reassembly

Step 8: Allow All Components to Dry Completely

ComponentDrying Method
Hood/HelmetAir dry upright on a clean surface 
Breathing tubeAir dry (ensure interior is dry if any moisture entered)
Blower unitWipe dry with lint-free cloth, then air dry
BatteryWipe dry, ensure connector contacts are dry
Belt/HarnessAir dry

Never reassemble or store PAPR components while wet. Moisture promotes bacterial growth and can damage electrical components .

Step 9: Inspect Components Before Reassembly

ComponentWhat to Check
Hood/HelmetTears, holes, damaged visor, worn elastic 
Breathing tubeCracks, creases, loose connections 
FilterClogging, damage, expiration 
Blower unitCracks, damaged seals, unusual noise
BatterySwelling, corrosion on contacts, reduced runtime

Replace any damaged or worn components immediately.


Filter Maintenance and Replacement

Filters are consumable items and must be replaced regularly .

Filter TypeReplacement IndicatorTypical Lifespan
Pre-filterVisible dust loading, discolorationDaily to weekly 
Main particulate filter (HEPA)Reduced airflow, audible alarm, visible damage40 hours of use or 30 days 
Gas cartridgeSmell or taste of contaminant, time-based scheduleVaries by manufacturer—follow label
Combination filterWhichever component fails firstFollow most conservative schedule

How to Check Airflow

Most PAPR systems include a flow check device or indicator:

  1. Disconnect the breathing tube from the blower

  2. Insert the flow meter into the blower outlet

  3. Turn on the blower

  4. Verify the indicator reaches the minimum flow level marking 

If airflow is inadequate:

  1. Replace filters and test again 

  2. If still inadequate, check for battery charge and blower function

  3. Remove unit from service if problem persists 

Junsee Group recommendation: Perform a flow check before every use—not just after cleaning .


Storage Guidelines

Proper storage extends PAPR component life and ensures readiness for the next use.

Storage RequirementSpecification
EnvironmentClean, dry area, away from contaminants 
Temperature0°C to 32°C (32°F to 90°F) ; or -10°C to +55°C (14°F to 131°F) depending on model 
HumidityLess than 90% RH 
SunlightAvoid direct sunlight (UV degrades plastics)
Heat sourcesAvoid excessive heat above 60°C (140°F) 

Additional Storage Tips

ItemStorage Instruction
BatteryPreferably store on charger to maintain optimal service life . If storing long-term without use, remove from blower, fully charge, and store separately 
HoodDo not tuck bib or extra material into headgear—this contaminates the breathing area
