Dyson DC28ci – Plus.Parts® Replacement HEPA Pre-Filter

The Dyson DC28ci is a variant in the DC28c family, sharing the compact corded bagless cylinder design and Root Cyclone separation technology of the range. Root Cyclone generates high-velocity rotational airflow to separate debris and fine dust centrifugally, no bag, no loss of suction from a bag filling up. Ultra-fine particles that pass through the cyclone array continue to the pre-motor HEPA filter, which performs two functions: blocking those particles from reaching the motor, and completing the allergen-capture role before the exhaust air returns to the room. Regular household vacuuming loads the filter media steadily with fine particulate, and airflow restriction builds gradually in a way that reduces suction output well before any physical degradation of the filter is visible.

This replacement is a single Plus.Parts® washable HEPA pre-filter dimensioned to the DC28ci’s filter housing for a direct-fit swap. Cold-water rinsing monthly restores airflow through the filter and extends the service period between full replacements. Dense media holds both motor-protection and allergen-capture performance stable across the complete service interval, maintaining the standard the Dyson DC28ci is designed to deliver through every regular maintenance cycle.
