Frequently asked
What is the 91978001?
The 91978001 is a Dyson vacuum replacement filter that fits 2 models in our data.
Is the 91978001 washable?
Yes - rinse with water only (no detergent) and let it air-dry fully, usually 24 hours, before reinstalling.
Is the 91978001 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.
