Even the most fastidious homeowner cleaning the bathroom, kitchen and floors never gives a thought to the duct work in the home. All sorts of chemicals are used to disinfect and sanitize every part of the home except the part that is most likely to affect your health, your duct work.
The air in your home is constantly circulating through the duct work in your floor or ceiling Bringing with it dust, pollen, pet hair and dander, grease and other pollutants. The air filter is generally beside your furnace which means that the return air duct gets coated with everything you would want to filter out of the air you breathe, as this layer of dirt builds up even clean air can be polluted by it.
Duct work and registers that are in the floor tend to collect just about anything that lands on the floor, dog food, dust, candy etc.
Considering we wouldn’t dream of wearing a dirty mask, would we really want to breathe the air coming through a duct that is a thousand times dirtier? There are companies that can vacuum clean and sanitize your ducts, if you have allergies ultraviolet lights can be added that kill bacteria that passes through the.
NOTE: The top photo is of a return air duct, check yours out and if they’re dirty maybe you want to consider your health and have them inspected, and professionally cleaned.
