Changing your air filter every 18 months is crucial for maintaining the health and efficiency of your HVAC system and vehicle engine. Don’t believe us? Here is Fram, a major air filter manufacturer and their recommendations. While the exact frequency can vary depending on usage and environmental factors, an 18-month interval serves as a reasonable benchmark for many situations.
Improved Air Quality and Health
Air filters trap dust, pollen, pet dander, and other airborne pollutants. Over time, these filters become clogged, reducing their ability to clean the air inside your home or vehicle. Regular replacement ensures that the air circulating is cleaner, reducing allergens and improving overall indoor air quality, which is especially important for individuals with allergies or respiratory issues.
Energy Efficiency and Cost Savings
A clogged air filter restricts airflow, forcing your HVAC system or engine to work harder to maintain desired temperatures or performance. This increased workload consumes more energy or fuel, leading to higher utility bills or fuel costs. Replacing the filter every 18 months helps maintain optimal airflow, improving energy efficiency and saving money in the long run.
Prolonged System and Engine Life
When air filters are dirty, the strain on your HVAC system or engine increases, which can lead to overheating, wear, and eventual failure of components. Regular filter changes reduce this strain, extending the lifespan of your system or vehicle engine and preventing costly repairs.
Environmental Benefits
Clean air filters promote better combustion in engines, reducing harmful emissions. Similarly, efficient HVAC systems consume less energy, lowering your carbon footprint.
In summary, changing your air filter every 18 months helps maintain cleaner air, improves energy efficiency, extends the life of your HVAC system or vehicle engine, and supports environmental sustainability. While some situations may require more frequent changes, adhering to this schedule is a simple yet effective maintenance practice.
