What is how often to change air filter?

Changing your air filter is a crucial part of maintaining your HVAC system and indoor air quality. Here's a breakdown of how often you should do it:

• General Recommendation: Most manufacturers recommend changing your air filter every 1-3 months.

• Factors Affecting Frequency:

  • Type of filter: Thinner, cheaper fiberglass filters typically need to be replaced monthly, while thicker, pleated filters can last up to 3 months. Higher MERV rated filters may need more frequent changes due to increased resistance.
  • Pets: Homes with pets, especially those that shed a lot, will require more frequent filter changes (every 1-2 months).
  • Allergies or Asthma: If someone in your household suffers from allergies or asthma, consider changing the filter monthly to improve air quality.
  • Home Location & Air Quality: If you live in an area with high levels of dust, pollen, or pollution, you'll need to change your filter more often. Construction nearby can also significantly impact filter lifespan.
  • Usage of HVAC system: If you run your HVAC system frequently, especially during peak heating and cooling seasons, change your filter more often.

• How to tell if your filter needs changing:

  • Visual Inspection: Check the filter regularly. If it looks dirty or clogged with dust and debris, it's time to replace it.
  • Reduced Airflow: If you notice reduced airflow from your vents, it could indicate a clogged filter.
  • Increased Energy Bills: A dirty filter can make your HVAC system work harder, leading to higher energy bills.

• Important Note: Always follow the manufacturer's recommendations for your specific HVAC system and filter type.
