Question: 1 / 400

Which condition can lead to the need for frequent air filter replacements?

High humidity

Dusty environment

Frequent air filter replacements are often necessary in dusty environments due to the increased accumulation of particulate matter. In such settings, dust particles can clog the filter quickly, reducing airflow and making the HVAC system work harder to maintain desired temperature levels. This not only impacts energy efficiency but can also lead to system strain and potential malfunction if filters are not changed promptly. Regular replacement of air filters helps ensure optimal air quality and system performance, making it crucial in areas where dust is prevalent.

High humidity, while it can affect air quality, doesn't necessarily lead to faster filter replacements compared to a dusty environment. Cold temperatures might affect the performance of the HVAC system and infrequent usage usually doesn't contribute much to filter clogging.
