Rainbow Respirator / Products and Applications

Rainbow Respirator
Rainbow Respirator

Air pollution levels are different, and the service life of the respirator is also different. When the air quality is good, the service life of the respirator is long, and the service life of the respirator is short when the air quality is poor. How can we know that our respirators can no longer be used? This rainbow respirator will tell you. The respirator has an indicator, which contains a material that can adsorb contaminants in the air. As the amount of adsorption increases, the colour of the indicator changes from green to yellow and then to red. When the bar becomes red, you can discard the respirator.
