Dyson DC37 Allergy Musclehead – Plus.Parts® Washable HEPA Filter

The Dyson DC37 Allergy Musclehead is a full-size corded bagless cylinder from Dyson’s DC37 range, combining two performance features: an allergen-specific accessory set designed to remove allergens from carpets, upholstery, and hard floors, and the Musclehead floor tool, which adjusts its height automatically as it transitions between carpet and hard flooring for consistent suction contact across surface changes. Both features operate on the same Root Cyclone separation platform, which spins incoming air and debris at high velocity to centrifugally separate large and medium particles before filtration. Fine particles, including ultrafine allergens, airborne dust, and microscopic debris that pass through the cyclone array, continue to the pre-motor HEPA filter, which intercepts them before the airstream reaches the motor. In allergy-focused households where the DC37 Allergy Musclehead covers multiple floor types with the allergen accessory set on a regular cleaning schedule, the pre-motor filter accumulates a combination of allergen-specific fine particulate and surface-transition dust steadily over successive sessions.

This replacement is a single Plus.Parts® washable HEPA pre-filter matched to the DC37’s pre-motor filter housing for a direct, tool-free drop-in installation. Cold-water rinsing monthly clears accumulated fine particulate from the filter media and restores airflow, extending the service interval before a full replacement is required. Dense media maintains consistent allergen capture and motor protection from installation through to the next scheduled maintenance, keeping the DC37 Allergy Musclehead performing at the allergen-removal standard it was built to achieve.
