The HEPA filter fits, but when I turn on the vacuum it makes a high pitched whistling noise and is very loud. It's possible that the filter isn't completely vacuum sealed and the air escapes to the outside and not through the filter itself. If so, then there's no point in using it. Bought 3 packs, all 3 work the same. What a waste of money. The only way out is to buy original filters.
