What Advanced Air Purification Does

Air purification picks up where filtration leaves off. A filter traps particles. Dust, dander, pollen. Physical stuff you could theoretically see under a microscope. Purification targets the things that exist as gases, odors, and living organisms. Volatile organic compounds from paint and flooring adhesive. Formaldehyde off-gassing from pressed wood furniture. Bacteria and viruses in the airstream. Mold spores small enough to slip through a MERV 16 filter. Those are the problems purification is built for.

The technology varies depending on what you are trying to address. There is no single device that does everything well, which is why we match the system to the specific air quality issue in your home. Here is what we work with:

  • Activated carbon filtration. Carbon absorbs gases and odors that mechanical filters ignore completely. Cooking smells, paint fumes, cleaning product residue, off-gassing from new furniture. If your house has a persistent chemical or musty smell that does not go away with ventilation, this is usually part of the answer.
  • Photocatalytic oxidation (PCO). A UV light hits a catalyst surface and creates a reaction that breaks down VOCs, bacteria, and mold at the molecular level. The contaminant does not get trapped. It gets destroyed. These units mount inside the ductwork and treat the air on every pass through the system.
  • UV-C germicidal lights. Ultraviolet light at the 254-nanometer wavelength kills bacteria, mold, and viruses on contact. We mount these on the evaporator coil or in the return plenum. They do not filter the air. They sterilize what passes through. Especially useful in homes where someone has a compromised immune system or recurring mold issues.
  • Bipolar ionization. Releases charged ions into the airstream that attach to particles, pathogens, and VOCs. The ions cause fine particles to clump together so the filter can catch them, and they deactivate bacteria and viruses on contact. This technology works passively and treats the air throughout the whole house, not just at the unit.

Some homes need one of these. Some need a combination. A house with heavy off-gassing from a recent renovation might get activated carbon plus PCO. A home with recurring mold and someone with asthma might get UV-C on the coil plus bipolar ionization in the supply plenum. We figure out the right mix after looking at your test results and your specific situation.
