Will the integrated soft sleeves collect dirt, mold, or mildew?


  • If left uncleaned, yes

  • As with other masks, wash with soapy water, rinse, let dry

If the integrated soft sleeves are not cleaned over time, they could collect dirt, mold, or mildew. However, the sleeves are easy to clean. Just dunk the whole thing in a dish bowl with warm soapy water (just like the F20).
