Comparison of Air Filter Media: Choosing the Right Filter for Cleaner Air


Air filters play a vital role in maintaining indoor air quality, trapping airborne particles and pollutants to provide cleaner and healthier air. However, not all air filters are created equal, as they come in different types and media with varying filtration capabilities. In this blog, we'll compare different air filter media to help you understand their strengths and select the most suitable filter for your needs.

  1. Fiberglass Filters: Fiberglass filters are the most basic and affordable option. They are composed of layered fiberglass fibers that capture larger particles like dust and debris. While they offer minimal filtration efficiency, they may not be effective in trapping smaller particles like allergens or mold spores.
  2. Pleated Filters: Pleated filters have more surface area due to their folded design, improving their ability to capture smaller particles. They are available in various MERV (Minimum Efficiency Reporting Value) ratings, offering better filtration performance compared to fiberglass filters.
  3. Washable Filters: Washable filters are reusable, environmentally friendly options. They are typically made of foam or mesh material and can be washed and reinstalled. However, their filtration efficiency is often lower compared to pleated filters.
  4. Electrostatic Filters: Electrostatic filters use static electricity to attract and capture particles. They are available as washable or disposable filters and can capture a wide range of particles effectively.
  5. Activated Carbon Filters: Activated carbon filters excel at removing odors, VOCs, and some chemicals from the air. They are often used in conjunction with other filters for comprehensive air purification.
  6. High-Efficiency Particulate Air (HEPA) Filters: HEPA filters are the gold standard in air filtration. They can trap up to 99.97% of particles as small as 0.3 microns. HEPA filters are highly effective in capturing allergens, dust, pet dander, mold spores, and even some bacteria and viruses. Typically, HVAC require specialized installations to enable the use of HEPA filters due to the increased pressure drop across the filte.


Choosing the right air filter media is crucial for maintaining healthy indoor air quality. Consider your specific air quality needs, budget, and the MERV rating that aligns with your requirements. Whether you need basic filtration for a residential setting or hospital-grade purification, there's an air filter media that fits your needs and provides cleaner air for you and your family. Regularly replacing or cleaning filters is essential to ensure optimal performance and fresher, healthier air in your indoor environment.

Consider using KorganoTech anti-pathogen MERV 13 and 16 air filters that are compatible with most HVAC systems (check HVAC system specifications).
