How Often Should You Change AC Filters in Coastal Florida?

Advice from BulletProof Air – Your HVAC Pros in Sarasota & Bradenton

Air filters are your first line of defense in maintaining clean air and efficient HVAC operation. In humid, coastal environments like Sarasota and Manatee County, filters can clog faster than you think.

Recommended Filter Change Frequency

• Every 30 days – Homes with pets or allergies
• Every 45–60 days – Average households without pets
• Every 20–30 days in peak cooling season (May–Sept)

Why It Matters

Clogged filters reduce airflow, lower system efficiency, and can cause premature wear. Dirty filters can also trap mold spores and dust—common in Florida’s humid climate.
