Perfect for our shark. Look and feel like the originals. We don't like to cling to filters for too long as we have a huge dog that sheds like crazy and it doesn't take long for those filters to start blowing out air that smells like dog. Hair! Even washing the white filters doesn't help after about 2 months. But that's because we basically vacuum every day. So for the price we have no problem with regular replacements and consider it a bonus that a HEPA filter comes with it! We'll last longer with this - maybe 3-4 months - but we're definitely just throwing away the soft filters now and replacing them. But we love our Sharks (now we have two models). One is over 5 years old and works well! As long as you keep them clean, changing filters and unclogging them, they look like real workhorses.
