I bought these primarily because of the price and the availability of multiple sets of each filter. The filter included in the collection canister (top left filter pictured) seems a bit flimsy compared to the Dyson branded filter (bottom left filter pictured) that comes with the vacuum. The materials feel a bit softer, which is probably why it doesn't feel as hard as the original. The ball filter doesn't seem to produce decent suction/blocking of the vacuum, so it makes a pretty loud squeaking noise when it's attached. The original Dyson brand filter does not. I will rate this a 1/5 until I get an acknowledgment from the seller regarding my concerns. Please watch the attached video. A new and clean filter is put on first to hear the squeak/squeak noise. Then the old, original and quite dirty filter is put back on to show that there is no noise.
