Terms of Service

1. No Professional Advice We are data analysts, not doctors or licensed HVAC contractors. The information on this site is for educational purposes. If you have serious health concerns, consult a medical professional.
2. Data Accuracy We use official historical datasets. Local air can change rapidly due to wildfires or weather events. Our advice is a baseline based on long-term patterns, not a real-time weather forecast.
3. Equipment Safety Before installing high-resistance filters (like MERV 13), check your HVAC manufacturer’s manual. We are not responsible for wear and tear or damage to your equipment.
4. Limitation of Liability FilterCents.net is provided "as-is." We aim for maximum accuracy, but using our recommendations is your choice and your responsibility.
