The filters are almost as good as the original OEM filters but I am a little concerned about the round black plastic pre-filter that the foam filter slides over . It doesn't snap onto the vacuum like the original and feels pretty loose just sitting on it. I'll probably just order this plastic filter from Shark and use the foam sleeves from that order as they seem to fit very well. The Hepa filter seems to fit well, although it's a little tighter. FYI, that was for the LZ602 Uplight Shark model.
