How often should smoke detectors be cleaned?

• A. Once a month
• B. Once a year
• C. At least twice a year
• D. Only when they malfunction

Answer: (C)

Smoke detectors should be cleaned at least twice a year to ensure they function effectively. Dust, debris, and other particles can accumulate inside the detector, potentially interfering with its ability to detect smoke. Regular cleaning helps to maintain the detector's sensitivity and reliability, contributing to fire safety. While cleaning once a month might seem like a proactive approach, it may be more frequent than necessary for most residential smoke detectors. Cleaning once a year would not provide sufficient maintenance to mitigate dust accumulation. Only addressing cleaning when a smoke detector malfunctions completely neglects the importance of preventative maintenance, which is essential for optimal performance and safety. Therefore, cleaning smoke detectors at least twice a year strikes a balance between sufficient maintenance and practical frequency for homeowners.
