Dispelling Air Filtration Myths for Improved Indoor Air Quality


Air filtration systems play a critical role in maintaining healthy indoor air quality, particularly in homes located in areas with high levels of outdoor contaminants, such as Charleston, South Carolina. These systems help to remove airborne pollutants, allergens, and irritants from your indoor environment, contributing to a healthier and more comfortable living space. However, several myths and misconceptions surrounding air filtration systems continue to circulate, leading some homeowners to question their effectiveness and necessity. 

Join Fix-It 24/7 Air Conditioning as we debunk common myths about air filtration systems, shedding light on their true benefits and capabilities. As a family-owned and operated full-service air conditioning, heating, and plumbing business, we are committed to helping you understand the importance of air filtration systems and how they can enhance the indoor air quality in your Charleston home.

Myth 1 – All Air Filters Are the Same

Fact: Air filters differ in their construction, filtration capabilities, and efficiency. They are designed to meet specific needs depending on the pollutants and contaminants present in your indoor environment. Key factors to consider when selecting an air filter include:

  • Material: Common filter materials include fiberglass, pleated cloth, polyester, and high-efficiency particulate air (HEPA) filters. Each material offers varying levels of filtration efficiency and airborne particle capture.
  • MERV Rating: The Minimum Efficiency Reporting Value (MERV) rating measures the effectiveness of an air filter. Residential filters typically have MERV ratings ranging from 1 to 13, with higher ratings indicating better filtration performance.
  • Size and Fit: Choosing the correct filter size and ensuring a proper fit is essential for optimal filtration and protection of your HVAC system.

Myth 2 – Air Filtration Systems Produce Ozone

Fact: While some air purifiers on the market do produce ozone as a byproduct of their operation, not all air filtration technologies contribute to ozone generation. High-efficiency particulate air (HEPA) filters, for example, do not produce ozone, as they rely on mechanical filtration to capture airborne particles.

If you are concerned about ozone generation, avoid air purifiers that use ozone generators or ionizers as their primary filtration technology. Instead, opt for HEPA filters or other non-ozone-producing systems designed to improve indoor air quality without potential negative side effects.

Myth 3 – My HVAC Filter Is Enough to Protect My Home’s Air Quality

Fact: While the filter in your HVAC system plays a crucial role in trapping airborne particles and protecting your equipment from dust and debris, it may not provide the level of filtration necessary to effectively remove all pollutants and allergens in your home. Standard HVAC filters often have low MERV ratings, meaning they may not capture smaller particles, such as bacteria, viruses, and fine allergens.

Upgrading your HVAC filter to one with a higher MERV rating can improve filtration performance, but it’s essential to consult with our professional HVAC technician before making any changes, as a filter with too high a MERV rating may restrict airflow and strain the system. Alternatively, consider adding a dedicated air filtration system to work in conjunction with your HVAC filter, providing comprehensive protection against a broad range of indoor contaminants.

Myth 4 – Air Filtration Systems Waste Energy and Increase Utility Bills

Fact: While it’s true that air filtration systems consume energy during operation, the overall impact on your utility bills is relatively minimal, particularly when compared to the potential health benefits and improved indoor air quality associated with their use. Moreover, modern air filtration systems are designed with energy efficiency in mind, often incorporating features like programmable timers, smart home integration, or energy-saving modes to minimize energy consumption.

Maintaining a clean and regularly serviced HVAC system can also contribute to energy efficiency, as a well-functioning system requires less energy to maintain comfortable indoor temperatures, ultimately reducing the strain on your air filtration system.

Myth 5 – Air Filtration Systems Require Constant Maintenance

Fact: While regular maintenance is necessary to ensure optimal performance and prolong the lifespan of your air filtration system, the frequency of required maintenance tasks varies depending on the specific system and filter type. Some air filtration systems, particularly those with HEPA filters, require more regular filter replacement, while others may have washable or reusable filters that need only be cleaned periodically.

In addition to filter maintenance, most air filtration systems require only minimal upkeep, such as occasional inspection of electrical components and cleaning of air inlets and outlets. With proper care and maintenance, your air filtration system will provide you with years of reliable performance.

Myth 6 – Air Filtration Systems Aren’t Necessary if I Don’t Have Allergies

Fact: While air filtration systems are particularly beneficial for allergy sufferers, they can also improve the overall air quality and comfort of your home for all occupants. Airborne contaminants like dust, pet dander, mold spores, and VOCs (volatile organic compounds) can negatively impact indoor air quality, leading to respiratory issues or other health problems, even in individuals without known allergies.

By investing in an air filtration system, you are creating a cleaner and healthier living environment for yourself and your family, potentially preventing the development of respiratory issues and providing a more comfortable home for all.
