The General Rule: Every 90 Days

For most homes, changing your air filter every three months is a good rule of thumb. This keeps your system running efficiently and prevents dust buildup.

Factors That Affect How Often You Should Change Your Filter

Some homes may need more frequent filter changes. Consider these factors:

✅ Pets in the Home: Pet hair and dander can clog filters quickly. If you have pets, aim to change the filter every 30 to 60 days.
✅ Allergies or Asthma: If someone in your household has allergies, changing the filter every 30 to 45 days can help keep allergens at bay.
✅ Urban or High-Pollution Areas: Living in a city or an area with poor air quality? Consider replacing your filter every 30 to 60 days.
✅ Seasonal Changes: During peak heating and cooling seasons (summer and winter), your system works harder, so check your filter monthly and change as needed.

Choosing the Right Air Filter for Your Home

Not all air filters are created equal! Here’s a quick guide to help you pick the right one:

🔹 Fiberglass Filters – Budget-friendly but need frequent replacement (every 30 days).
🔹 Pleated Filters – A great balance of cost and efficiency; change every 60-90 days.
🔹 HEPA Filters – Best for allergy sufferers; change every 30-60 days.
🔹 Washable Filters – Reusable, but need regular cleaning to remain effective.

Signs It’s Time to Change Your Air Filter

Not sure if your air filter needs changing? Look out for these signs:

🚩 Higher Energy Bills: A clogged filter makes your HVAC system work harder, increasing energy costs.
🚩 Dusty Home: If you’re constantly battling dust, your filter might be full.
🚩 Weaker Airflow: Poor airflow from vents can signal a clogged filter.
🚩 More Allergy Symptoms: If your family is sneezing more than usual, your filter may not be catching allergens effectively.

Easy HVAC Maintenance for a Happy Home

Regularly checking and replacing your air filter is a simple and cost-effective way to extend the life of your HVAC system and improve indoor air quality. Mark your calendar, set a phone reminder, or tie it to another routine home task—just don’t forget!

A clean air filter means better airflow, cleaner air, and a healthier home—and who doesn’t want that? 😊

It’s important to note that seller concessions don’t mean the buyer will get cash back. Instead, the seller typically agrees to put part of their home sale proceeds toward the ...
