The user must determine, by suitable testing, the correct method on the CleanSpace respirator for their particular application. For advice on sterilization contact the CleanSpace Service Team.


Before sterilization, remove used filters and insert the CleanSpace Cleaning & Storage Plug (CS3011) and clean the respirator thoroughly to remove foreign material (follow the steps in Cleaning the Respirator).

Work in a clean environment and ensure good hand hygiene. Wear personal protective equipment (PPE) including nitrile or vinyl gloves during the cleaning and sterilization process. Remove the CleanSpace Cleaning & Storage Plug Set (CS3011) before sterilization.


The mask, neck support and head harness (non-electronic parts) can undergo chemical or thermal cycling sterilization methods. NOTE: Ethylene oxide is carcinogenic and its use for respirator equipment should be considered carefully before use.

Table 1. Sterilization Methods and Their Compatibility
Sterilization Method Problematic Parameters Compatibility
Chlorine dioxide None There are no adverse effects on electronics or batteries.
Gamma ray Radiation, nuclear waste The radiation can damage semiconductors that are not designed for exposure.
Electron beam Radiation The radiation can damage semiconductors that are not designed for exposure.
Autoclave steam High temperature, humidity Can affect floating-gate memory cells (EEPROM); reduces the lifetime of embedded batteries (if any).
Ethylene oxide Flammability, carcinogen Vacuum can affect embedded batteries.
Vaporized hydrogen peroxide Vacuum Vacuum can affect embedded batteries.
Hydrogen peroxide plasma Vacuum, plasma discharge Vacuum can affect embedded batteries; the RF energy required to generate the plasma may not be compatible to semiconductors.
When storing the power unit, use the CleanSpace Cleaning & Storage Plug Set (CS3011) to prevent contaminants entering the power unit air path.

CHARGING: 0˚C to 35˚C in a dry and protected space

STORAGE: –10°C to +35°C (–4°F to +131°F) at <90% relative humidity. Away from direct sunlight

EACH MONTH: We recommend INSPECTING the respiratory for damage, cracks or missing parts. Please check the mask exhalation valve. If tearing or distortion of the valve, the exhalation valves should be changed.

EVERY 6 – 12 MONTHS: Harness and neck pads should be replaced depending on the level of use, every 6-12 months. The masks are made of silicone and resilient to aging and wear and tear. Close inspection of the mask should be conducted at least annually. The Respiratory Protection Standards recommend a fit test annually to confirm the correct fit of the mask

This information is a guide only and should be reviewed thoroughly by your HSE manager prior to selecting the disinfecting product for your equipment and specific application. Please note CleanSpace has not evaluated the effectiveness of any agents with regard to inactivating biological material on these products. IMPORTANT: Components of respiratory systems may become damaged over time with prolonged or extended use of disinfecting products.
