Frequently asked
What filter(s) fit a Dyson DC27 vacuum?
The Dyson DC27 uses the 91978001 (washable) filter.
Does the Dyson DC27 use a HEPA filter?
Our data doesn't list a HEPA filter for the Dyson DC27.
Should I buy the OEM filter or an aftermarket one?
The genuine filter is the safe, exact-fit choice. A cheaper aftermarket filter can fit the same slot too - check reviews for real-world fit and suction performance before buying, since vacuum filters generally aren't independently certified the way NSF-listed water filters are.
How often should I replace or wash my vacuum's filter?
Washable filters should be rinsed (water only, no detergent) every 1-3 months and fully air-dried for 24 hours before reinstalling. Non-washable filters are typically replaced every 6-12 months, or sooner if suction drops.
