How Do HEPA Filters Work? Camfil Air Quality Experts Explain.
HEPA filters are highly effective at trapping particulate matter such as dust, pollen, pet dander, viruses, and bacteria, and to ensure maximum efficiency, it is important to replace them regularly.
HEPA filters have become a popular choice for many people and businesses looking to improve indoor air quality. These filters have a higher percentage of small pollutants captured than other types of air filters. But how exactly do HEPA filters work?
HEPA, which stands for High-Efficiency Particulate Air, is a mechanical air filter. Unlike MERV or MERV-A filters, HEPA filters physically capture particulate matter through their three-dimensional structure of ultra-fine fibers. To catch particles, HEPA filters do not require ionization or UV lamps.
There are three global test standards to classify HEPA filters. One standard uses particles 0.3 microns and the minimum removal efficiency to be considered a HEPA filters 99.97%. The other two standards rely on the MPPS (Most Penetrating Particle Size) to classify HEPA filters and those standard begins at 99.95% capture efficiency on MPPS.
HEPA filters are highly effective at trapping particulate matter such as dust, pollen, pet dander, viruses, and bacteria. They are frequently utilized in medical buildings, laboratories, and other environments where air quality is critical.
Replacing your HEPA filter at the proper time is important to ensure maximum efficiency. Over time, HEPA filters can become clogged, reducing airflow through the filter. You can ensure that your indoor air quality remains high and that you breathe clean, healthy air by carefully following the manufacturer's recommendations on filter replacement. .
The most crucial step when selecting a HEPA filter for an existing system or an individual room air purifier with a HEPA filter is to ensure it has been tested, certified, and labeled as a genuine HEPA filter.
