• Universal DIY Customization & Cut-to-Fit Design — Features a large 400x300mm (15.7x11.8 inch) high-density PVC mesh that offers maximum flexibility for custom PC builds. This DIY dust filter can be easily trimmed with household scissors to fit any non-standard computer case, fan intake, or ventilation opening, ensuring a perfect fit for brands like Corsair, NZXT, and Fractal Design.
• Optimized Airflow & Cooling Performance — Engineered with a precise 1.2mm fine hole diameter, this protective mesh strikes the ideal balance between dust filtration and air intake. It effectively traps airborne particles while allowing massive airflow to reach your CPU cooler and GPU fans, maintaining stable system temperatures and preventing thermal throttling during intense gaming or rendering.
• Magnetic Tool-Free Installation System — Includes 8 high-strength 400mm magnetic strips for instant, tool-free attachment to steel or metal PC chassis. This magnetic mounting system allows for flexible placement on top, front, or side panels without the need for screws or messy adhesives, making it the perfect accessory for quick case modding and hardware protection.
• Comprehensive Hardware Protection & Longevity — Provides a robust shield against dust, pet hair, and dander, which are leading causes of fan failure and hardware overheating. By keeping your internal components clean, it extends the lifespan of expensive hardware like RTX graphics cards and power supplies (PSU) while maintaining the clarity of your internal RGB lighting setup.
• Washable & Reusable Premium PVC Material — Crafted from eco-friendly, corrosion-resistant PVC material that is built for long-term durability. This washable dustproof cover can be easily removed, rinsed under water, and reused without deforming or losing its filtration efficiency. It offers a cost-effective and sustainable cooling solution for gaming rooms, home offices, and server racks.

• Measure & Cut — Measure your vent opening, then trim the PVC mesh with household scissors for a precise fit.
• Attach Magnetic Strips — Place the 8 magnetic strips along the edges of the mesh, then attach to steel or metal case panels.
• Secure & Test — Ensure the mesh is firmly attached, check airflow, and clean periodically by rinsing under water.
