10-Pack of PM 2.5 Filters for Cloth Face Masks

10-Pack of PM 2.5 Filters for Cloth Face Masks

Regular price USD $10 USD

These disposable filters can be easily inserted into your Unbelts cloth masks to create a third layer between your droplets and the outside world.

Blocking over 99% of particulate matter measuring 2.5 microns or larger, they contain five layers:

  • Softspun nonwoven polypropylene fabric 1
  • Meltblown filter 1
  • Activated carbon
  • Meltblown filter 2
  • Softspun nonwoven polypropylene fabric 2

To use, insert in our adult masks as-is, or into our kids’ masks by folding (not cutting) the two bottom corners. Each filter measures approximately 3” x 5”.

Filters can be used for 16-24 hours of continuous use, or until damp; they can be used for approximately a week of occasional wear. Be sure to remove your filter before washing your Unbelts mask, and wash your hands before and after handling.  

Our filters’ efficacy is independently tested by SGS, one of the world’s leading inspection, verification, testing, and certification companies. 

// Remember, even with a filter, out masks are non-surgical and non-medical grade. They are not designed to replace medical-grade PPE.

// For your safety, all Better Together Collection items are final sale.
