The best way to clean these products is to hand-sponge with warm water and mild detergent, rinse, and air-dry. After cleaning and before reassembling, inspect all parts of the product for any signs of damage. Be sure when cleaning air supply hoses, flow controls or breathing tubes that you do not allow water to enter the product. 

These products can be machine-washed in cold or warm water using a gentle cycle and a mild laundry detergent. Air-dry only. After cleaning, carefully inspect for signs of damage.

In addition to warm soap and water, the following chemicals have been tested and approved as cleaning agents for the EVA blower unit, belt, and battery:  

  • Process NPD (1.256) from Steris 
  • Spor Klenz (undiluted) from Steris 
  • Clorox liquid bleach at 10% concentration 
  • Sani-cloth HB wipes 
  • 100% Methanol 
  • 70% IPA 

The exterior filter/cartridge of EVA can be gently wiped down with a dry or damp cloth. Be sure water does not enter the filter/cartridge. If water enters the filter/cartridge, replace it. Do not use gasoline, organic-based solvents, or chlorinated degreasing fluids to clean the EVA PAPR. Refer to the EVA User Manual for further details on cleaning and disinfecting the PAPR.

  1. Mechanical laundering of loose-fitting hoods is not recommended 
  2. For cleaning, use warm water, mild dishwashing liquid and a soft brush to remove any dirt from exterior surfaces.  
  3. As per CDC guidelines* for disinfection, diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective to disinfect exterior surfaces.  
  4. Thoroughly rinse the loose-fitting hood with clean, fresh water and allow to air-dry 

Additionally, Bullard has tested several common decontamination and cleaning agents to determine if the integrity of the loose-fitting hood has been compromised after decontaminating. Based on this testing, it was determined that the loose-fitting hoods did not suffer any significant degradation when cleaned with these agents after eight times. It is important to understand that Bullard did not test and cannot test for sterility after cleaning, and therefore cannot make a determination about the effectiveness of the cleaning/decontamination agent when used on this respirator component.

  • Decon Alcohol (Veltek) 70%
  • Decon Spore (Veltek) 6.4:128 concentration

 Important Notes: 

  1. Dupont was not involved in this testing and does not endorse the finding shown here. The decision to reuse a respirator and the selection of the cleaning agent is entirely the responsibility of the employer. 
  2. Other agents not included in the testing that share similar active ingredients to those agents listed above: 
  • Vitrex Tb 
  • Sani Cloth Plus 
  • TB Quat 
  • Cidex 
  • Bleach-Rite

*According to the Centers for Disease Control and Prevention (CDC), the recommended method to remove contamination to prevent the spread of Coronavirus Disease 2019 (COVID-19) from garments when working with a case of laboratory-confirmed COVID-19 or a person under investigation is laundering and drying per instructions from the clothing manufacturer.

SENTINEL1 & 2: use mild soap and water to clean the ABS crown protector and never use bleach because it can degrade the plastic. A disinfectant can be used and will not damage the crown protector. 

Acetate Visors: can be cleaned using disinfectant wipes and other agents such as peroxide type disinfectants. Acetate has a very strong chemical resistance so if in doubt try cleaning a small area of the visor before cleaning the entire visor. 

Tritan Visors: have a lower chemical resistance than Acetate and can be cleaned as noted above. If in doubt, try testing a small area of the visor before cleaning the entire visor. 

Polycarbonate Visors: polycarbonate has little to no chemical resistance and using mild soap and water work best. Be sure there is no lotion in the soap being used as this will cause streaking of the visor. 

Polyester Visors (These visors are designed as single use)
