Question: Are these one-time use? If yes, how long do they last, minutes? hours?? If no, can the filters be replaced?
Document: The American Certification gives me confidence that this is a totally effective product.Hope I never need to use this, but just having it gives me a sense of comfort.
I purchased this fire hood so that I could be secure in the event of a fire, especially in light of the recent wild fires in my area. Knowing that I can safely breathe without being affected by the toxic gasses while fleeing a harmful environment gives me peace of mind. Everyone should keep one or more of these in their homes to protect themselves and their families!
What else can we say, except its about four times the size of the largest other hood we have seen. Makes me feel like it has a real filter inside the sealed bag. It passed by our inspector for a good quality smoke hood so we figure it is the best of the smoke hoods.
I did my research and with all of the product test results and certification provided, this by far seems to be the best smoke hood on the market. Thank you for giving me confidence to purchase this product.
