Debunking Common Misconceptions About Indoor Air Quality

O'Dell's Heating & Cooling • March 11, 2025

There's an old saying, "The air we breathe matters." This is especially true when it comes to the air inside our homes and workplaces. Indoor air quality (IAQ) has become a significant health concern, thanks to several factors that contribute to poor air conditions. However, a wealth of misconceptions surrounding IAQ often prevents homeowners from making the best decisions for their health.


At O'Dell's Heating & Cooling, we believe in empowering our customers with accurate and actionable information about their indoor air. So, let's debunk some common misconceptions about indoor air quality.


Misconception 1: Indoor Air is Cleaner than Outdoor Air


One of the most common myths about IAQ is that the air inside our homes is cleaner than the air outside. Contrary to this belief, the Environmental Protection Agency (EPA) reveals that indoor air may be up to 5 times more polluted than outdoor air due to a confined space and lack of ventilation. Factors such as dust, pet dander, mold, pollen, household chemicals, and even some building materials can degrade indoor air quality.


Misconception 2: Air Fresheners Improve Air Quality


Many people use air fresheners or candles to keep their homes smelling fresh and clean. While these can make your home smell good, they don't improve air quality. In fact, they can contribute to indoor air pollution as they emit volatile organic compounds (VOCs) and other chemicals into the air.


Misconception 3: Only Allergens in the Air Affect Indoor Air Quality


Indoor air quality isn't just about allergens such as pollen or pet dander. Other factors can significantly impact your home's air quality, including moisture and humidity levels, mold and bacteria growth, and the presence of chemicals from household products. Good indoor air quality management involves monitoring and controlling all these factors.


Misconception 4: Indoor Air Quality Problems Can’t Be Prevented


This is a common misconception that leads many homeowners to ignore the quality of their indoor air. The truth is there are numerous ways to prevent and improve poor indoor air quality. Regularly cleaning and maintaining your HVAC system, using air purifiers, controlling humidity levels, and ensuring proper ventilation can all drastically improve your home's air quality.


Misconception 5: DIY Methods Are Enough to Improve Indoor Air Quality


While DIY methods such as regular cleaning, houseplants, and opening windows can contribute to improving your air quality, they may not be enough, especially if you have severe air quality issues. Professional air quality services such as ventilation system installation and maintenance, air purifier installation, and duct cleaning are designed to address more serious concerns and significantly improve your indoor air.


Misconception 6: More is Better When It Comes to HVAC Filters


Many people believe that using higher-rated HVAC filters will naturally lead to better air quality. However, super-efficient filters can actually restrict airflow in your HVAC system, causing it to work harder and reduce its lifespan. The best course of action is to choose a filter with a suitable MERV rating for your specific system and change it regularly.
