What is Molecular Filtration?
Molecules are the chemical building blocks of everything in our world from water to human tissue, to plastics to petrol, to poisons to foods. The kind of molecules that concern us in HVAC are typically 1000 times smaller than the particles removed by the highest efficiency ULPA filters that remove viruses!
If we think the number of small particles in city center air is high, the corresponding figure for molecules is astounding. For any gas or vapor at what is a very low concentration of 1 part per billion in air, there are approximately 2,500,000,000,000,000 molecules per cubic meter, or 2.5 million molecules per cubic millimeter! There is no particle filter that can handle these types of contaminants; this is when molecular filtration is required.
HOW IS MOLECULAR FILTRATION APPLIED? Airborne molecules impact businesses in several ways: 1) As odors 2) As irritants 3) As toxins or poisons 4) As corrosive and/or yield impacting agents
Many molecules are known to be harmful to humans, the environment, manufacturing processes (microelectronics, pulp and paper, oil refining, etc.) and more sensitive items such as artifacts in museums and art galleries. Understanding the environment that you are in, the functions of your facility, and assets within your building is essential to selecting the most appropriate molecular filtration solution.
This blog will serve as the ultimate guide to molecular filtration.
