About FilterCents The Concept Most people buy air filters by guessing. They grab whatever is cheapest or whatever happens to be on sale at the local hardware store. We think that’s a mistake. The filter in your home should be chosen based on the air quality outside your front door—not a marketing promo. What We Did We’ve spent months digging through massive archives of historical air quality data across the U.S. We took the dry, technical numbers for PM2.5 (fine dust), ground-level ozone, and community asthma rates and turned them into a simple, logical system. We aren't a "corporate team" in suits, and we don't install HVAC systems. We are an independent resource that connected environmental statistics with actual filter specs to show you exactly what’s happening in your neighborhood. The Scale Our database covers over 26,000 locations. For the 2,500 largest cities, we’ve built deep-dive guides: We don’t just look at "averages." We look at peak spikes—because your lungs don’t breathe annual averages; they breathe the air on the worst days. We factor in local reality: humidity, seasonal pollen cycles, and regional geography. We explain when you actually need a high-end MERV 13 filter and when it’s just a waste of money that might strain your HVAC motor. Why FilterCents? We help you find the sweet spot. You want a filter that actually cleans the air during smog or pollen seasons but doesn’t "choke" your system the rest of the year. No complex jargon—just straight recommendations based on the air in your specific city. Affiliate Disclosure How We Keep the Lights On FilterCents.net is a free resource. To keep our servers running and update data for 26,000 locations, we use affiliate links. If you click a link and buy a filter, we may earn a small commission at no extra cost to you. Our recommendations are driven by local air quality data, not by which brand pays the most. We suggest the right MERV rating for your situation; where you buy it is up to you. Privacy Policy Your Privacy We don’t want your personal data. FilterCents.net does not require registration, and we don’t collect names or phone numbers. What we see: We analyze where our traffic comes from so we can serve the correct local air data. Cookies: We use standard cookies to understand site traffic and ensure our affiliate links work properly. Third Parties: If you leave our site to visit a retailer, you are subject to their specific privacy rules. 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. in Kansas
