What makes a Dirty air filter such a big deal?  

  • Deteriorated Indoor Quality: First off, a blocked air filter makes it tough for your HVAC system to tackle airborne pollutants like dust, pollen, and germs. This can lead to poor indoor air quality, which may trigger respiratory issues like asthma and allergies—especially concerning for Ohioans, where changing seasons bring various allergens. 
  • Elevated Energy Expenditure: When your HVAC system has to work extra hard to push air through a jammed filter, your energy bills can skyrocket. According to a study by the Department of Energy, swapping out a dirty filter for a new one can reduce your air conditioner’s energy use by 5% to 15%. With Ohio’s unpredictable weather, it’s essential to ease the workload on your HVAC system! 
  • System Failure: Ignoring your air filter can lead to more than just poor air quality and higher bills. If you let those filters get too dirty, your HVAC system will struggle, which can lead to serious breakdowns and hefty repair costs down the line. 
  • Pollutants and Contaminants: A clogged filter allows harmful pollutants and contaminants to roam freely in your home. This includes things like mold spores, pet dander, and tobacco smoke particles, which can lead to various health issues, from mild irritations to more serious respiratory infections. 
  • Accumulation of Dust and Debris: One of the most immediate effects of a clogged air filter is the rapid build-up of dust and debris in your home. You might notice your furniture getting dusty quicker, and your HVAC vents could start to collect dust too. This not only affects cleanliness but also means you’re inhaling those particles regularly. 
  • Germs and Bacteria: A less obvious but equally concerning issue with a congested air filter is the potential spread of germs and bacteria. A dirty filter can become a breeding ground for harmful microbes that circulate throughout your home, which can worsen respiratory conditions. 
  • Escalated Allergy Indicators: If you notice that your allergy symptoms are getting worse no matter what you do, it might be time to check your air filter. Sneezing, coughing, and itchy eyes can all get worse with poor indoor air quality. 
  • Ominous Odors: A blocked air filter can lead to some unpleasant smells in your home, ranging from musty to downright nasty, depending on what’s trapped in there. Staying on top of air filter changes can help you avoid those unwanted odors! 

Keeping your air filter clean is a simple way to ensure your home stays comfortable, healthy, and budget-friendly! 

How often should you replace your Dirty air filters?  

  • Seasonal Shifts: With Ohio’s big seasonal changes, it’s a good idea to check your air filter at the start of each season. This helps ensure your HVAC system is ready to handle whatever the weather throws at it year-round. Generally, we recommend changing air filters every 30-90 days, depending on how much you use your system and your lifestyle. 
  • Post-Renovations: If you love tackling DIY projects, remember that renovations can kick up a lot of dust and debris. It’s smart to replace your air filter after such projects to keep it from clogging up! 
  • Pet Owners: If you have furry friends, you’ll want to change your air filters more often. Pet dander and fur can pile up quickly and impact your home’s air quality.
