Dust filter set for Cooler Master MasterBox NR200P by DEMCiflex, model 1101

DEMCiflex dust filter set model 1101 is designed as a direct replacement for the Cooler Master MasterBox NR200P chassis. The set contains specifically shaped filters that fit the NR200P intake and ventilation openings to reduce dust ingress, helping to keep fans, radiators and internal components cleaner and maintain designed airflow characteristics.

Advantages

The DEMCiflex filters are manufactured from fine mesh material that captures airborne dust while still allowing adequate airflow for case cooling. Using replacement filters helps preserve thermal performance by preventing dust accumulation on heatsinks and fan blades. The set is intended to be easy to install and remove for periodic cleaning, supporting routine maintenance without modifying the chassis.

Suitable for

• Owners of Cooler Master MasterBox NR200P seeking replacement or spare dust filters
• Routine PC maintenance to reduce dust accumulation on fans and radiators
• Small-form-factor builds where maintaining airflow and component longevity is important

Key specifications

• Compatible chassis: Cooler Master MasterBox NR200P
• Filter type: fine mesh dust filter
• Function: reduces dust ingress to case interior and components
• Material characteristics: washable/reusable mesh (cleanable by rinsing or vacuuming)
• Placement: designed for intake and ventilation openings of NR200P

How to use

Turn off and unplug the PC before removing the case panels. Remove the existing filters or open the filter frames on the NR200P where the DEMCiflex pieces are to be installed. Fit each filter into the corresponding opening, ensuring it seats correctly and does not obstruct panel closure. For routine cleaning, remove the filters, rinse under lukewarm water or use a soft brush or low-power vacuum to remove dust, allow to dry completely, then reinstall.

Recommendations

Inspect and clean the filters every 1–3 months depending on the environment; more frequent cleaning is recommended in dusty or pet-friendly environments. Always allow washed filters to dry fully before reinstalling to prevent moisture contacting components. Replace filters when mesh shows wear or damage to maintain filtering effectiveness.
