WHY COULDNT MY BAGS LAST AS LONG AS THEY USED TO?/KTMT Filter
Normally because they are working harder. Bag's life is limited by the amount of dust captured, not by hours they are used. Bags filtering clean working environment can last a year, while a bag filtering high dust containing plant may only last a few weeks. A product can appear clean to the naked eye and still be full of particles that are too small to see.
