Air Sanitizing: No viruses, No bacteria
In the United States, a sanitizer is a disinfectant that is intended to disinfect or sanitize, reducing or mitigating growth or development of microbiological organisms including bacteria, fungi or viruses on inanimate surfaces in the household. Unlike air purifiers, which filter or otherwise trap particles within an air circulator, air sanitizers have the ability to act on airborne microorganisms in your duct.
You have to know that it is perfectly possible for viruses to accumulate in your air vent. The more serious problem is that they can easily spread to the rest of the house via the heating, ventilation and air conditioning system . While the risks to your HVAC system may not be as serious as those facing hospitals and healthcare facilities, the same principals apply.
Luckily, there are some things you can do to reduce the potential for an airborne infection from being transmitted through your HVAC system. When you get your air ducts sanitized you are ensuring that the ducts your air is moving through do not have any lingering pathogens. This means when the air gets to you, the air that you are breathing is of a significantly higher quality.
