AirTrim Cold Air Mask

AirTrim Replacement Filters Asthma

Replacement Asthma filters for the AirTrim cold weather mask.


There are five different models which allow different volumes of airflow. This is a pack of 2 asthma filters.

  • Asthma Filter: Lowest airflow and highest heat recovery. For those with Asthma, or for use in cold temperatures at low intensity levels.
  • Race Filters: Highest airflow, lowest resistance, and least warming for high-intensity activity. Race 1 is the highest resistance and warming of the race filters, Race 2 is mid-range, Race 3 is the least resistance/highest airflow.
  • Sport Filter: Medium airflow and resistance, warms air significantly and is used for light- to moderate-intensity exercise.

Sport and Racing filters available separately.

Filters should be dried completely after each use. With adequate care, each filter should last for 20-30+ sessions.  Airtrim Mask comes with the sport filter installed and a spare asthma filter.
