How to Disinfect Forced-Air Vents
"Dust in the Wind" is not just a song -- it's also what can happen if forced-air vents are not periodically cleaned and disinfected. Bacteria also can build up on the surfaces of registers, grilles and air diffusers, both inside and out. Traces of mold dispersed from an air vent can cause health problems. Disinfecting your air vents also lets you breathe a little easier knowing that the air coming from your vents is not passing over a layer of germs en route to the rooms in your home.
