Walton & Company’s mission is to make every building we touch more efficient and safe, including our own facilities. The in-duct air purifiers installed in our buildings, and being installed on our customer’s buildings in Pennsylvania and Maryland, are designed to help eliminate “Sick Building Syndrome” risks by reducing air pollutants and odors that survive, thrive and spread through the duct systems of large facilities. Its effectiveness is in three categories of indoor air pollutants: particulates, microbial, and gases. It drastically helps reduce allergy triggers and kills up to 99% of bacteria, mold, and viruses. We are doing our part by eliminating the spread of COVID-19, however, the work we do for you doesn’t stop when the virus is gone. We will continue to service your building at the highest level of professionalism you’d expect. Please contact our Building Services Manager, Bill Vervaeke, on how you can protect your facility, today at, email@example.com, or 717-755-9030.
Hype #1 Ionizing Systems: Many ionizing systems produce ozone, but others use cold plasma, hydroxyl radicals or ionized hydrogen peroxide to kill bacteria and viruses. While extensive testing and EPA statements have called out the dangers of ozone on people’s respiratory systems, less is known about the long-term effects of these other systems. The bottom line is they all use oxidation as their primary method for killing bacteria and viruses and until more is known about the long-term health impacts of these other systems, we cannot recommend them for indoor use.
Hype #2 Coil Cleaning: Keeping HVAC system coils clean is critical for their efficient operation and should be done as needed based on the environment those coils are in. While it is possible for particulates, including viruses and bacteria, to be found on coils, it likely won’t make much of a difference reducing the spread of viruses. This is especially true of coils on rooftop units where only particulates from outdoor air will be found.
Hype #3 Central HEPA filtration: According to the Centers for Disease Control, the novel coronavirus spreads primarily through respiratory droplets when an infected person coughs or sneezes. Those droplets generally fall to the ground or land on other surfaces within six feet. While it is possible for viruses to become suspended in the air for several hours and travel farther, as a result, this is not the primary means of transmission. At this time, based on the cost and practicality of retrofitting HEPA filtration (which may require significant system modifications) when compared to any possible benefit, we can’t recommend this for most settings.
