How a 20x24x1 Air Filter Impacts HVAC Replacement, Indoor Air Quality, and Energy Savings?

When people of the house tell me that they have gotten an HVAC replacement and then ask me, as a consent, whether using a 20x24x1 air filter can indeed make some difference, I can only respond by defending what we have observed to be the case: it can and does actually make a difference. During our field experience, we have observed a reduction in the number of breakdowns, a decrease in the energy bill per month, and a happy indoor environment when systems are fitted with an ideal 20x24x1 filter in comparison to those that do not have ideal filters installed. Not only this is theory, but this has been tried and judged by years of work-at-hand results and customer opinions. In this guide I will explain why spending money on buying the proper 20x24x1 air filter when replacing your HVAC is one of the smarter things you can do both in regard to efficiency over time and the health of your family down the line.

Top Takeaways

• The 20x24x1 air filter is crucial in HVAC replacement.
  
  

• Proper sizing = better airflow + 5%–15% lower energy bills.
  
  

• Quality filters cut indoor pollutants by up to 50%.
