Why Replace My Lennox Healthy Climate X6673 Furnace Filter?

Your Lennox Healthy Climate X6673 furnace filter isn’t meant to last as long as your HVAC system – in fact, it is a disposable component that needs to be replaced regularly to help your heating and cooling equipment work properly and to improve air quality in your home.

  • If you don’t replace your Lennox Healthy Climate X6673 furnace filter, it won’t provide you with the level of filtration you expect. As the filter media fills with contaminants over time, it will no longer be able to pull more contaminants from the air.
  • If you don’t replace your Lennox Healthy Climate X6673 furnace filter, you’ll be compromising the performance and longevity of your heating and cooling systems. A dirty filter won’t keep contaminants out of your HVAC system – dirt, dust, and debris can compromise system components, causing breakdowns. Your system also will not receive the airflow needed to work effectively and efficiently. This disastrous combination leads to more energy use, more wear and tear to your system, and more breakdowns – leading to less years of service and increased costs for you.
  • If you don’t replace your Lennox Healthy Climate X6673 furnace filter, your home’s cleanliness will suffer. When an air filter can’t remove airborne contaminants, they circulate back into your home, settling on surfaces. You’ll notice the excess dust and dirt and will be cleaning more frequently.
