i recently purchased these paper bags for my upright vacuum and they have made a world of difference. My analysis of this product showed that they are extremely durable and hold a lot of dirt and debris before needing to be changed. The construction of the bags is fantastic and they fit perfectly with my vacuum model .One downside is that they are a little pricey compared to other brands, but the quality and performance is worth it. Overall, I highly recommend this product for any home and kitchen vacuum needs..
