Dyson DC33c Extra – Plus.Parts® Washable HEPA Pre-Filter

The Dyson DC33c Extra is a DC33c variant supplied with an extended accessory bundle, broadening surface and task coverage beyond the standard configuration while retaining the same Root Cyclone separation platform. Root Cyclone spins incoming air and debris at high velocity to centrifugally separate large and medium particles before the airstream reaches filtration. The fine fraction that passes through the cyclone array, ultrafine dust, airborne particles, and microscopic debris, continues to the pre-motor HEPA filter, positioned between the cyclone output and the motor, where it intercepts fine particulate before it can reach or damage the motor. Running the DC33c Extra across a wider range of surfaces and attachment types, as the extended bundle is intended to support, increases the volume of fine material the filter processes across a typical service period, compressing the airflow reduction cycle relative to lighter use.

This replacement is a single Plus.Parts® washable HEPA pre-filter matched to the DC33c Extra’s filter housing for a direct drop-in installation. Monthly rinsing under cold water removes accumulated fine particulate and restores filter airflow, extending the useful interval before a full replacement is needed. Dense media maintains consistent fine-particle capture and motor protection from installation through to the next replacement, preserving the performance the DC33c Extra’s extended accessory range was designed to support.
