How Often Should You Change a Dirty Air Filter? 

The consequences of a dirty air filter are much scarier than you think. Have you ever stopped to think about what happens when your HVAC air filters are allowed to remain clogged for long periods of time? Such an issue may appear trivial, but bear in mind that obstructed or dirty air filters can seriously disrupt the purity of your indoor air alongside your overall well-being and reap other adverse effects. Well, today at Newark-Heath Heating & Cooling, we aim to enlighten Ohio homeowners about the potential perils of overlooked air filters to avert unnerving HVAC-related ramifications.  

What makes a clogged air filter so concerning?  

  • Poor Indoor Air Quality: A blocked air filter reduces your HVAC system’s ability to filter out pollutants like dust, pollen, and germs, leading to poor indoor air quality. This can worsen respiratory issues like asthma and allergies, especially in Ohio, where changing seasons bring various allergens.  
  • Higher Energy Costs: When your HVAC system has to work harder to push air through a clogged filter, energy consumption goes up. According to research by the Department of Energy, replacing a dirty filter with a new one can lower your air conditioner’s energy use by 5% to 15%. With Ohio’s unpredictable weather, it’s crucial to prevent your HVAC system from overworking.  
  • System Breakdown: Another thing to keep in mind is that when you ignore your air filter changes, it can lead to more than just poor air quality and higher bills. As a result, failing to change your filters can strain your HVAC system, leading to costly breakdowns and repairs down the line.  
  • Circulation of Harmful Contaminants: A clogged air filter allows harmful pollutants and contaminants, like mold spores, pet dander, and tobacco smoke, to circulate in your home. These can cause health issues ranging from mild irritations, like sore throats, to serious conditions, like respiratory infections.  
  • Dust and Debris Buildup: One of the most immediate effects of a clogged air filter is the rapid buildup of dust and debris in your home. This is because furniture gets dusty quickly, and HVAC vents may start accumulating dust, too. When this happens, it will impact your home’s cleanliness and means you’re inhaling these particles regularly.  
  • Spread of Germs and Bacteria: A less obvious but serious consequence of a clogged filter is the spread of germs and bacteria. Unfortunately, a dirty filter can become a breeding ground for harmful microbes, which then circulate throughout your home, worsening pre-existing respiratory conditions.  
  • Increased Allergy Symptoms: If you’re experiencing allergy symptoms despite taking medication, check your air filter. Symptoms like sneezing, coughing, and itchy eyes can worsen with poor indoor air quality.  
  • Unpleasant Odors: A blocked air filter can cause bad odors in your home, ranging from musty to foul, depending on what’s trapped in the filter. By staying on top of filter changes, you can avoid these unwanted smells.  

How often should you replace your air filters?  

  • Seasonal Changes: In Ohio, with its drastic seasonal changes, it’s a good idea to check your air filter at the start of each season. This helps ensure your HVAC system can handle year-round demands. Generally, we recommend changing air filters every 30 to 90 days, depending on how much you use it and your lifestyle. 
  • After Renovations: If you often do DIY projects at home, remember that renovations can release a lot of dust and debris into the air. It’s wise to replace your air filter after these projects, as the dust can quickly clog it. 
  • For Pet Owners: If you have multiple pets, you should change your air filters more frequently because pet dander and fur can build up quickly, affecting your home’s indoor air quality (IAQ). 

Keeping your air filter clean is essential for your HVAC system and ensuring good indoor air quality. By recognizing when your air filter is clogged and knowing how to address it, you can maintain a healthy, welcoming home. Don’t wait until it’s too late! Make air filter maintenance a regular part of your home care routine. With these tips, you’ll be ready to tackle any air filter issues that arise.
