February 22, 2026ยทMarketing Renovation Team
Why This Matters
The air filter is your HVAC's first defense. A dirty filter increases bills and causes failures.
Key Signs to Watch For
- Visible dirt: If you can't see through it, replace.
- Higher energy bills: Clogged filter restricts airflow.
- More dust: Saturated filter stops capturing particles.
What You Should Do
-
Standard 1-inch: Replace every 30-90 days.
-
Pleated: Last 90 days.
-
HEPA: Replace every 6-12 months.
-
Check monthly during peak seasons.
