Use Airtrim breathing mask when it is cold outside. The air you breathe in through the filter becomes warmer and humid by your exhaled air. Your airways are therefore protected against dry and cold air. With Airtrim you are able, without extra effort, to walk, work out and stay outside longer in the winter.
Don’t forget to dress warmly though. It is easy to forget that it is cold when the air you breathe is warm.
