Regular filter replacement is one of the most important yet often neglected maintenance tasks. Understanding proper filter selection and replacement procedures helps maintain system efficiency and indoor air quality.

Choose the right filter for your system by considering both the size and MERV rating. Filters that are too restrictive can reduce airflow and strain your system, while insufficient filtration allows dust and debris to accumulate on sensitive components. RM Mechanical can recommend the optimal filter type for your specific system.

Replace filters according to manufacturer recommendations and usage patterns. Most homes benefit from filter replacement every 60-90 days, but homes with pets, allergies, or high dust levels may require monthly changes. Check filters monthly and replace when visibly dirty.

Proper installation is crucial for filter effectiveness. Ensure the filter faces the correct direction (look for arrows indicating airflow direction) and fits securely without gaps. Improper installation can allow dust to bypass the filter, reducing indoor air quality and system efficiency.

Mark your calendar or set phone reminders for regular filter checks. Consider enrolling in RM Mechanical's maintenance program, which includes regular filter service as part of comprehensive system care.
