Reusable face masks
(mouth-nose masks)


With ear loops or to tie

 

We offer these mouth-nose masks made of cleanroom fabric as a replacement for disposable face masks made of nonwoven fabric.

They are not a 100% replacement for them, but, due to the general fabric properties of ION-NOSTAT VI.2 , these reusable textile washable face masks  are conceivable for many cleanroom applications. 

Each customer is therefore asked to check on his own responsibility whether this option is suitable and can be used for his requirements.

face mask to tie, 21 cm wide, Art.-No. 1745DAST1

Our textile, washable face masks can be decontaminated and sterilized like the reusable cleanroom garments.

Professional reprocessing/decontamination by a cleanroom laundry is recommended, this also applies to newly delivered face masks. 

  • Garments made of ION-NOSTAT VI.2 has been successfully used for over 15 years in cleanrooms of air cleanliness classes ISO 4 and ISO 5 as well as in sterile areas (GMP A-/B-zones).
  • Values for the bacterial filtration efficiency (BFE) are currently not available.
  • In most cases the breathing resistance of textile fabric face masks is higher than that of disposable ones.
  • The wearing times are likely to be shorter than for disposable ones.
Important additional note: 
For various reasons, these textile makeshift masks cannot be equated with disposable medical face masks. They are not tested or certified face masks and are in no case to be regarded as a replacement for filtering half masks (FFP2/FFP3). Furthermore, they are no PPE articles.

The colours vary between olive green, white and light blue, depending on availability.
