These bags may be slightly smaller than Miele's; they look smaller. They work very well and are comparable to Miele bags except for the size. I also like that they include filters - mine were shot. I've never had Miele scented balls and that's a nice touch. A word of caution for homes with young children: the packaging is flimsy and the pellets are quite green in color. The smell should be enough to deter them, but with children you never know for sure.
