Over time, dust, dirt, or oil residues may accumulate on the vent surface, blocking microholes and reducing venting efficiency.

• Use a soft, lint-free cloth or a low-pressure air blower to remove surface debris
• Avoid harsh brushes or abrasive materials that could scratch the vent membrane
• For stubborn residues, use a mild, non-corrosive cleaner and wipe gently
• Never soak the vent in liquid, as this may damage internal protective layers

Implement targeted environmental protection based on your operating conditions.

• In humid environments, ensure the vent is paired with additional waterproof enclosures if needed
• Check periodically for condensation buildup around the vent
• Wipe away moisture promptly to prevent membrane degradation or metal component rust
• In dusty or industrial settings, install compatible dust shields over the vents
• Replace shields if they become worn or torn
• Avoid exposing vents to extreme temperatures for prolonged periods

Conduct regular inspections to ensure your MEMS vents are functioning correctly.

• Every few months, verify the vent's pressure balance function
• In devices like smartphones or earbuds, test if audio quality remains consistent
• Inspect the vent's physical structure for signs of damage
• Look for cracks in the housing, peeling adhesive, or membrane tears
• If the vent is mounted with fasteners, check that they are tight
• Prevent gaps that allow unfiltered air or moisture entry

Follow these practices to ensure long-term reliability of your MEMS vents.

• Avoid subjecting devices with MEMS vents to unnecessary physical impacts
• Shocks can dislodge the vent or damage its internal structure
• When replacing or reinstalling vents, align them correctly with the device's housing
• Ensure a tight seal to prevent premature wear
• Never attempt to modify the vent
• Modification will compromise its protective capabilities and shorten its lifespan
