Query: Great value

Recently bought a range hood that has activated charcoal post-filters (behind the steel ones), which is important for my set up because the fan doesn't vent to the outside (recirculates into the kitchen). The manufacturer of the hood wants $50 for two filters. I could probably buy a lifetime supply using this product and cutting it to shape. Does a great job of reducing smoke and particulants into the air. So far, very happy with the performance, thickness and value for the money. Would definitely recommend to friends and family.
