HEPA vs. Non-HEPA Filters: Understanding the Best Choice for Your Air Quality


Air filters play a vital role in maintaining clean and healthy indoor air. When it comes to selecting the right filter for your HVAC system or air purifier, you will likely come across two primary options: HEPA and Non-HEPA filters. Understanding the differences between these two types of filters can help you make an informed decision about the best choice for your air quality needs.

HEPA Filters

HEPA, which stands for High-Efficiency Particulate Air, is a standard set by the U.S. Department of Energy. To be classified as a HEPA filter, it must meet stringent requirements and capture at least 99.97% of particles as small as 0.3 microns in size. These filters are highly effective in trapping a wide range of airborne particles, including dust, pollen, pet dander, mold spores, and even some bacteria and viruses.

Non-HEPA Filters

Non-HEPA filters, also known as standard or basic filters, come in various forms, including fiberglass, pleated, and washable filters. Unlike HEPA filters, they do not meet the same rigorous efficiency standards. Non-HEPA filters generally capture larger particles, such as dust and pollen, but may not be as effective at trapping smaller particles like mold spores or bacteria.

Key Differences

Filtration Efficiency: The most significant difference between HEPA and Non-HEPA filters lies in their filtration efficiency. HEPA filters are far more effective at capturing a higher percentage of particles, including the tiniest ones, making them the top choice for individuals with allergies, asthma, or other respiratory conditions.

Airflow and Resistance: HEPA filters are thicker and denser than Non-HEPA filters, which can lead to increased resistance in airflow. As a result, HVAC systems or air purifiers that use HEPA filters may require more powerful fans to maintain adequate airflow.


Choosing the Right Filter

Selecting the appropriate filter depends on your specific needs and circumstances. If you or your family members suffer from allergies or asthma, or if you want the highest level of filtration, investing in a HEPA filter is recommended. On the other hand, if you are looking for a more affordable option and have no severe respiratory concerns, a Non-HEPA filter might be sufficient for general particle removal. . KorganoTech Air filters are available in MERV 13 for homes and MERV 16 for businesses. Higher-rated air filters are also available upon request. Notably, you can reduce the spread of airborne viruses, bacteria, and allergen with KorganoTech’s drop-in HVAC air filters infused with silver and copper particles.

In Conclusion

Choosing between HEPA and Non-HEPA filters is a crucial decision when it comes to maintaining good indoor air quality. While HEPA filters offer superior filtration efficiency and are highly beneficial for allergy sufferers and those with respiratory conditions, Non-HEPA filters can still provide satisfactory performance for general particle removal. Consider your specific needs, budget, and the size of your space when making the choice. Regularly replace or clean the filters as recommended by the manufacturer to ensure optimal performance and cleaner, healthier air in your living or working environment.
