The efficiency of the HVAC air filtering system is critical to good indoor air quality in buildings. These systems have been developed to keep up with the changing demands of the building inhabitants. Originally meant to keep heating and cooling coils free of dust and dirt accumulation, these systems have evolved to keep up with the changing needs of the building residents.
Manufacturers have improved the performance of current filtering systems to fulfill this demand. There have been advancements in technology that can successfully decrease or eradicate many sorts of pollutants.
Mechanical Air Filters:
The mechanical air filter is the most extensively utilized filtering system in building HVAC systems. The filters are made of spun glass or a high-loft, non-woven material and work by straining and impinging particles against the filter material. The filter’s effectiveness is the rate at which the filter medium eliminates particles from the air flowing through it.
Filters With A Gaseous Phase:
While mechanical air filters are good at removing particle pollutants from the HVAC system, they cannot eliminate all contaminants. Automatic air filters, for example, have little effect on gaseous pollutants. While HEPA filters may remove particles as small as 0.3 microns, gases and vapors are 0.01 microns or smaller. Activated charcoal is the most frequent material used in gas-phase systems.
Filters That Emit Uv Light:
Biological pollutants are just too tiny for mechanical air filters or gas-phase filters to be effective. Many biological pollutants can be killed or deactivated by UV light at the correct wavelength and high enough doses. UV radiation has been used to sterilize surfaces, water, and the atmosphere for over a century. They’ve been utilized to keep biological development on coils at bay in HVAC systems.
Solutions That Think Beyond The Box:
While the HVAC system has been the focus of most efforts to supply clean, conditioned air in buildings, building managers have many stand-alone choices. In most buildings, the concentration of pollutants in the atmosphere varies by area and by the actions done in those spaces. You may produce large amounts of dust in some regions.
No one filter will suit the requirements of all facilities. The first stage in delivering clean air is understanding the kind and amount of contamination present in the facility and the level of cleanliness required. Managers may pick and select, or even combine, filters that will benefit their operations the most, given the possibilities available today. Any inquiries about these filters, like RoboVent, should be sent to an expert.
