Why Air Filters Matter
Your HVAC system relies on a clean air filter to function efficiently. A dirty or clogged filter can restrict airflow, making your system work harder and reducing indoor air quality. Regular filter replacement helps maintain energy efficiency, prolongs your HVAC system’s lifespan, and ensures cleaner air in your home.
How Often Should You Replace Pleated Air Filters?
For most homes, pleated air filters should be replaced every 3 months. However, several factors can require more frequent changes:
- Pets in the Home – Pet hair and dander accumulate quickly, meaning you may need to replace your filter every 1 to 2 months.
- Frequent AC Usage – If your air conditioner runs constantly, it pulls in more dust and debris, clogging the filter faster.
- Allergies or Respiratory Issues – If someone in your home has allergies or asthma, replacing the filter every 1 to 2 months helps maintain better air quality.
Pleated Filters vs. Washable Filters
When choosing an air filter, homeowners often debate between pleated filters and washable (electrostatic) filters. Here’s how they compare:
Pleated Air Filters
- Made from tightly woven fibers that capture dust, pollen, and debris.
- Higher efficiency at trapping allergens and small particles.
- Disposable and easy to replace every few months.
- Higher MERV ratings (Minimum Efficiency Reporting Value) for better filtration.
Washable & Reusable Filters
- Can be cleaned and reused, reducing waste and long-term costs.
- Require regular washing and complete drying before reinstalling.
- Typically have lower MERV ratings, meaning they may not trap as many fine particles.
- Can develop mold or bacteria if not properly cleaned and dried.
Final Thoughts: Which One is Right for You?
If you want convenience and better filtration, pleated filters are the best choice. If you’re looking for an eco-friendly option and don’t mind frequent maintenance, washable filters might work for you. Regardless of the type you choose, regularly checking and replacing your air filter is key to keeping your HVAC system running smoothly and maintaining clean air in your home.
