In modern life, indoor air quality is critical to our health and comfort. High Efficiency HVAC (Heating, Ventilation, and Air Conditioning) air filters, specifically High Efficiency Particulate (HEPA) filters, excel at removing tiny airborne particles. These filters are effective at capturing particles as small as 0.3 microns in diameter, with a removal rate of over 99.97%.
How HEPA filters work
HEPA filters use randomly arranged fiber mesh, usually made of polypropylene or glass fibers, with a diameter of about 0.5 to 2.0 microns. As air passes through these fibers, particulate matter is captured through mechanisms of interception, inertial collision and diffusion. This multiple capture mechanism makes high efficiency filters excellent at removing fine particulate matter.
Advantages of HEPA filters
Superior filtration: HEPA filters are capable of removing more than 99.97% of 0.3 micron particles in the air, including harmful substances such as dust mites, pollen, mold spores, bacteria and viruses.
Enhances Indoor Air Quality: By effectively removing harmful airborne particles, HEPA filters help reduce allergy symptoms, improve respiratory health, and enhance the comfort of the living and working environment.
Extend the life of your HVAC system: HEPA filters can effectively remove airborne particles, reduce dust buildup inside the system, reduce maintenance costs, and extend the life of your HVAC system.
Considerations when selecting an HEPA filter
MERV Rating: MERV (Minimum Efficiency Reporting Value) is a measure of air filter efficiency. In general, filters with MERV 13 and above are suitable for environments requiring high air quality.
System Compatibility: When selecting an HEPA filter, the design and specifications of the HVAC system need to be considered to ensure that the selected filter is compatible with the system to avoid compromising air flow and system performance.
Maintenance and Replacement: Regularly inspect and replace filters to maintain optimal performance. Replacement every 3 months is generally recommended, but the exact frequency should be based on the environment in which it is used and the type of filter.
