These are great filters that are suitable for a vacuum cleaner but have nothing exceptional about them. The filter that came with the vacuum cleaner lasted over a year. I know we probably should have changed sooner, but I cleaned the filter regularly and it kept going! I have three dogs and the new filter can't handle the dog hair. It's definitely cheaper to buy filters from other manufacturers, but mine filled up after only 2-3 months, so I'm not sure if the cheaper price is really worth it. If you are looking for a quick fix with quick delivery I would recommend it however it is not the highest quality.
