Kids' PM 2.5 Filters

Regular price CAD $10 CAD

These replaceable polypropylene filters can be easily inserted into your Unbelts face covering to create a three-layer mask, in accordance with Health Canada's updated guidelines.

Blocking over 99% of particulate matter measuring 2.5 microns or larger, they contain five inner layers, including polypropylene, the Government of Canada's recommended material for inner filters.

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

To use, insert in our masks as-is. Each Kids' filter measures approximately 3” x 5”, Pre-schooler measures approximately 2.75" x 4".

Filters can be used and re-used for up to 16 hours total. If your filter becomes damp, remove it with clean hands and allow it to dry before re-inserting. 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, our 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.
