Details

From Sweden, Airtrim Respirators help skiers in cold weather by recovering both moisture and warmth allowing for easier breathing, greater overall body warmth, and reduced chances of exercise-induced asthma. Our testers report significantly better warmth and comfort in the upper torso severely cold weather. Airtrim may allow you to ski comfortably in conditions that were previously too cold! Non-returnable once packaging is opened.
* Note: These respirators are intended for airway humidification, not filtration. They do not provide filtration for viruses or other pathogens.

Temperature measurements in the breathing air with Airtrim
The temperature was measured 1 cm inside and 1 cm outside the filter. The measurements were made on a volunteer in a room with a temperature of -22°C and -10°C.

We have unfortunately no test results from using racing filters. However, the lower air resistance normally gives a lower inhaling temperature than the sport filter.

The measurements were made at the Arbetslivsinstitutet in Solna, Sweden.
