NASHVILLE, Tenn. (WTVF) — Some homeowners and business owners are asking professionals to disinfect their spaces using an electrostatic sprayer.

At the start of the pandemic, Holly Horncastle and Dana Nappi realized people needed a way to fight COVID-19. “We found a hospital-grade disinfectant solution that is non-toxic but 99.99% effective at killing the coronavirus as well as flu.”

Their company, Purified, has been getting a lot of house calls. “And so we’ll make sure that there’s no COVID-19 virus, any of the pathogens in the area. Then they’ll have their event,” Horncastle said, “and then after that, we will come out the next day and spray, so anything that’s been brought in with the guests will leave as soon as we spray.”

When it comes to disinfecting surfaces, most people are doing it wrong. Nappi and Horncastle were trained by the Global Biorisk Advisory Council on how to wipe down surfaces. Nappi said, “They said you need to spray, wipe it sideways.” Swirling your paper towel in a circular motion only spreads germs around on the surface. Some solutions need to sit on the surface for up to 10 minutes before wiping it down. In addition, using color-coded rags is helpful so you can remember which one you used to clean.

Recently, they’ve also disinfected homes where people were previously sick or exposed to COVID-19. The sprayer gives them the ability to reach difficult spots. “It adds a magnetic charge to the disinfectant, so when we spray on a surface it not only adheres to the top of the surface, but it encapsulates the surface.”

With the holidays ahead, Holly and Dana expect to be busy due to the ‘twindemic,’ when flu season and COVID-19 collide.
