How often do I replace HVAC air filters?

Indoor air quality (IAQ) is very important for several reasons. Poor IAQ can have adverse health effects, particularly for those with allergies or respiratory issues. It can also lead to unpleasant odors and discomfort. Poor IAQ can also impact the efficiency and lifespan of your HVAC system by causing a buildup of dirt and debris, which can lead to costly repairs and replacements. Additionally, good IAQ can improve productivity and overall well-being, particularly for those who spend a lot of time indoors. IAQ can be improved through various means, including regular cleaning, air purifiers, and proper ventilation.
