These filters completely stop airflow and make a mess when you throw the can in the bin. While shipping was fast and the seller probably doesn't know that these fake filters don't fit like the original manufacturer filters, the filter clogs and stops airflow sooner than it should. Since you can't find the original filters, you're probably stuck with them; Just remember to clean them often so you don't waste time vacuuming when the airflow stops due to a clogged filter.
