What Are HEPA Filters and What Particles Do They Trap?

HEPA filters are designed to capture and remove a wide variety of particles, including very small particles. In fact, HEPA filters are rated based upon their ability to trap particles as small as 0.3 microns. Particles that are as small as 0.3 microns are equivalent in size to smoke or even viruses. Particles of this size are known to cause issues with breathing and other allergic reactions. Here are some of particles that can be captured with a quality HEPA filter:

  1. Dust and Dust Mites: These filters can trap dust particles along with microscopic dust mites. These are common allergens that can cause respiratory issues and allergic reactions.
  2. Pollen: HEPA filters help capture even the tiniest of pollen grains, which are known to trigger allergies, especially during the allergy season.
  3. Pet Dander: If you have pets, HEPA filters can effectively capture tiny pet dander particles, which is a common allergen for many people.
  4. Mold Spores: HEPA filters are capable of capturing mold spores which can be present in a home or business, especially in damp areas, and are known to cause breathing problems.
  5. Smoke: HEPA filters are effective at removing different kinds of smoke particles, including cigarette smoke, wildfire smoke, and smoke from cooking.

Discover the Power of MERV Ratings: Your Guide to Cleaner Air

MERV Rating

One essential factor in achieving cleaner air is understanding MERV ratings. MERV, which stands for Minimum Efficiency Reporting Value, is a standard measurement used to evaluate the performance of air filters.

In general terms, filters come with a MERV rating which help you determine how effective an air filter captures and traps particles of different sizes. Particles that may be in homes and businesses include dust, pollen, pet dander, mold spores, and even some bacteria and viruses. MERV ratings range from 1 to 20 with the higher the MERV rating, the more particles the filter can capture.

Below is a breakdown of MERV ratings and what particles you can expect each level to capture:

  • MERV 1-4: These filters will capture larger particles like dust and pollen. While they may not be as effective in removing smaller particles, they still offer some improvement in air quality.
  • MERV 5-8: Filters in this range can capture smaller particles like mold spores and pet dander, making them suitable for general home use.
  • MERV 9-12: Filters within this range are considered to have good filtration efficiency. They effectively capture smaller particles, including much finer dust particles, allergens, and some common household pollutants. People with allergies and asthma should consider MERV 9-12 filters.
  • MERV 13-16: These filters provide excellent filtration, capturing even smaller particles down to bacteria and a large portion of viruses. These filters can be commonly found in hospitals, commercial buildings, and in residential applications for those with severe allergies or respiratory conditions.
  • MERV 17-20: Filters in this range offer the highest level of filtration available. They are made for specialized applications, such as cleanrooms and hospitals, where the highest level of air purity is essential. MERV 17 is similar to the HEPA filter standard.

When choosing an air filter, it’s important to consider your unique needs and the desired air quality. While higher MERV ratings provide superior filtration, it’s important to ensure your HVAC system is compatible with the selected filter’s pressure drop. Consulting with an HVAC professional can help you determine the best MERV rating for your system and ensure optimal performance. Ensuring a safe and comfortable home relies heavily on residential air treatment.

Breath of Fresh Air: Resolving Allergies, Asthma, and More with Field Control Filters

By removing particles from the air, HEPA filters can minimize health issues, including:

  1. Allergies: By filtering out a large portion of the allergens in the air, individuals can see a reduction in symptoms like sneezing, coughing, and itchy eyes.
  2. Asthma: Allergens in the air can trigger asthma symptoms. HEPA filters remove dust, pollen, along with pet dander, making the air cleaner and healthier.
  3. Respiratory Issues: By improving overall air quality, the ability to breathe freely increases.

By effectively capturing particles down to 0.3 microns, HEPA filters enhance the overall indoor air quality, creating a fresher and cleaner home or business.
