Fit perfectly, so glad I saved money with choosing this brand

These bags were perfect. Did have to jump through hoops like other cheap ones. Just put them in and they work great.

Works great, didn’t notice any difference between this and the name brand.

They fit fine but they are much smaller than the original ones we had. The filters are a little chintzy, but they fit after trimming with scissors.
