I bought these filter bags to replace the original bags that came with the Love Less ash I bought 24 years ago. The bags must be fireproof and by and large this has been confirmed but recently the outer bag was burned out by embers. The inner bag stayed intact so the ash dust was not thrown out and I only found the problem when emptying the vacuum. In this day and age, with products and companies coming and going, it was great to see that Love-Less Ash Co are still making great ash vacuums and still stand behind their old products. I called Love-Less to see if there were vacuum bags available for my old vacuum and was informed that the same bags that were used in my old vacuum are still being used in new vacuums. Easy to install, cheap price, great customer service. Can't ask for more.
