How often should I replace my air filter?

Most homeowners should replace filters every 1-3 months. Homes with pets, allergies, or smokers may need more frequent replacements to maintain optimal airflow and indoor air quality.

What does MERV 5 mean?

MERV (Minimum Efficiency Reporting Value) rates filter effectiveness. MERV 5 captures larger particles like dust and lint, providing basic air quality improvement without restricting airflow or straining your HVAC system.

Are pleated filters better than flat ones?

Yes. Pleated filters offer more surface area, capturing more particles and lasting longer between replacements while maintaining better airflow than standard flat filters.
