Dust Filter DEMCiflex Dark Base Pro 900 Rear – replacement rear dust filter

The DEMCiflex Dark Base Pro 900 Rear replacement dust filter is a purpose-built accessory for the Dark Base Pro 900 PC case. Designed to cover the rear exhaust and ventilation openings, this filter captures dust particles before they enter or exit the chassis, helping to maintain cleaner internal components and more consistent airflow. It is a direct-fit replacement intended for routine case maintenance and long-term protection of fans, heatsinks and ventilation channels.

Advantages

This replacement rear dust filter offers effective particle filtration while preserving airflow performance due to its low-profile, permeable material. The direct-fit design simplifies installation and removal for regular cleaning. Made to match the Dark Base Pro 900 layout, the filter reduces dust buildup on components, which can contribute to more stable cooling and reduced maintenance frequency.

Suitable for

• Replacing a worn or damaged rear dust filter in the Dark Base Pro 900 chassis
• Routine maintenance to reduce internal dust accumulation
• Improving longevity and cleanliness of fans and heatsinks
• Systems that require straightforward, tool-free filter access

Key specifications

How to use

Turn off the PC and, if necessary, disconnect power before accessing the rear of the chassis. Remove the existing rear filter by releasing any clips or frames that secure it, then slide or lift the DEMCiflex replacement filter into the same position until it sits securely. Reconnect power and resume normal operation. Clean the filter periodically by removing accumulated dust with a soft brush or low-pressure air; allow it to dry fully if washed with water before reinstalling.

Usage recommendations

Inspect the rear dust filter every few months or more frequently in dusty environments. Clean with gentle brushing or compressed air rather than aggressive washing to preserve material integrity; when washing is necessary, use lukewarm water, avoid detergents, and ensure complete drying before reinstalling to prevent moisture-related issues.
