FITS ALL STANDARD FAN SIZES — CUTS TO SHAPE: The large 50cm x 50cm sheet cuts easily to fit 80mm, 92mm, 120mm, and 140mm PC case fans.

STOPS DUST BUILDUP — PROTECTS YOUR PC: This 3mm open-cell foam filter traps dust particles before they reach fan blades, heatsinks, and GPU coolers. Reduces internal cleaning frequency by up to 80% and prevents dust-related thermal throttling — extending the life of your components. WASHABLE & REUSABLE — LASTS FOR YEARS: Unlike disposable filters, this foam sheet is washable under running water. Air dry fully before reattaching. Rated for 200+ wash cycles without losing filtration effectiveness. One purchase lasts the lifetime of your PC build. BALANCED AIRFLOW & FILTRATION — 3MM OPTIMAL THICKNESS: The 3mm construction is purpose-engineered to balance dust capture with unrestricted airflow. Thinner than felt alternatives, it does not choke your fans or increase noise levels. Tested to maintain airflow rates within 5% of unfiltered performance. COMPATIBLE WITH ALL PC CASES: Works with Corsair, NZXT, Fractal Design, be quiet!, Phanteks, Cooler Master, Lian Li, and all other brands. Ideal for fresh builds, upgrades, and replacing failed adhesive mesh filters. Also suitable for air purifiers, dust cabinets, and HVAC vent covers.
