Frequently Asked Questions
Q: What thickness should I choose – 3mm or 5mm?
A: The 3mm sponge filter is ideal for tight spaces and slim fan mounts where clearance is limited. The 5mm option provides slightly more filtration depth, making it a great choice for dusty environments or larger cabinet openings where a thicker barrier is beneficial.
Q: Can I cut this sponge filter to fit my specific fan size?
A: Absolutely! The 500×400mm sheet is intentionally oversized for DIY versatility. Use scissors or a craft knife to trim it to any shape or size — perfect for 80mm, 120mm, 140mm fans, or custom panel cutouts.
Q: How do I clean the sponge dust filter?
A: Remove the filter and rinse it under running water, gently squeezing out the trapped dust. Allow it to dry completely before reinstalling. Regular cleaning (every 1–3 months depending on your environment) will maintain optimal airflow and filtration performance.
Q: Is this filter compatible with both intake and exhaust fans?
A: Yes. The low-resistance 60PPI foam works well on both intake and exhaust positions, though it is most effective on intake fans where it can intercept dust before it enters the enclosure.
