**Q: Can this filter carbon monoxide?**
A: Carbon Monoxide is a dangerous gas and can displace breathable air in a poorly ventilated, enclosed space.  CBRN filters are not an effective solution and should not be used in any oxygen deficient environment.  20,000 emergency room visits every year are caused by CO poisoning.  The best solution for CO is to ventilate area well with fresh air.  To ensure you can work in an environment with CO you need an SCBA (self-contained breathing apparatus) and appropriate training.
