I am planning to use these with the mask while misting the house with Vector-Ban or Sector Misting, and am wondering if I have to change the filters for every application, or if these can be reused a few times? $35 each time is pretty expensive.
You do not have to change Comfo Classic P100 Cartridges out after every use. The general rule of thumb is that they need to be changed when you are able to smell odors in the room you are treating while you are wearing the mask.
