Can liners be cut or trimmed?Updated a month ago

We do not recommend cutting or modifying the liners.
Cutting may cause:
- Cotton to fray
- Edges to curl
- Incorrect alignment
- Blocked vent holes
- Airflow issues
- Bigger leaks
If a liner seems too large or too small, it may be the wrong SKU for your mask.
We can help you identify the correct size.
