Don’t Forget to Do This Before Turning On Your AC!
Summer’s around the corner — but before you crank up that air conditioning, there’s one critical thing you can’t skip: cleaning your AC filters.
Whether you have a central air system or a window unit, clean filters protect your health, boost energy efficiency, and help your system last longer. Here’s why it matters (and how to do it right)!

Health Risks of Dirty AC Filters
Over time, AC filters trap dust, pollen, pet dander, bacteria, and even mold spores.
If neglected, these contaminants blow straight back into your home’s air.
Health risks include:
- Respiratory Issues: Dirty air worsens asthma, allergies, and other conditions.
- Infections: Bacteria and viruses can spread through your ventilation.
- Mold Exposure: Clogged filters create perfect environments for mold growth.
- Fatigue and Headaches: Poor air quality can cause discomfort, headaches, and dizziness.
👉 Especially with window units, outdoor pollutants like smog and pollen get sucked inside if the filters aren’t clean.

Health Benefits of Clean AC Filters
A clean filter isn’t just about comfort — it’s an investment in your health.
Benefits include:
- Trapping allergens and pollutants efficiently
- Reducing respiratory symptoms for sensitive family members
- Preventing mold outbreaks in ducts and systems
- Creating a fresher, more livable environment
Think of cleaning your filter as an air “reset button” for your whole house!



Boost Performance and Save Energy
Keeping filters clean also makes a huge difference for your AC’s performance.
Advantages:
- Better Airflow: Cool air moves faster and more consistently.
- Prevent Freezing: Dirty filters can cause coils to ice over, leading to shutdowns.
- Avoid Overheating: Reduced airflow strains the motor and compressor.
Energy Savings:
According to the U.S. Department of Energy, replacing a dirty filter can lower your AC’s energy consumption by up to 15%.
Over one summer, that can add up to major savings!
How Often Should You Clean or Replace AC Filters?
General Guidelines:
- Standard homes: Check and clean/replace every 1–3 months.
- Homes with pets/allergies: Check monthly.
- During heavy use (summer): Check monthly even if no pets.
Window Units:
- Wash reusable filters once a month with warm, soapy water.
- Always dry completely before reinstalling to avoid mold.
Quick Rule:
👉 If it looks dirty, it is dirty. Don’t wait!
