Frequently asked
What is the 91781901?

Is the 91781901 washable?
Our data doesn't list this filter as washable - treat it as a replace-only part.
Is the 91781901 a HEPA filter?
No - our data doesn't describe this filter as HEPA.
Is a cheaper compatible filter as good as the OEM one?
A compatible filter that physically fits isn't automatically equivalent - check reviews for real-world fit and suction performance, since vacuum filters generally aren't independently certified the way NSF-listed water filters are.
