Pets in the home
Cats and dogs shed dander and odors that settle in your ductwork. Sanitizing after a clean helps knock down the smell and bacteria they leave behind.

Air Duct Sanitizing & Virucide in St. Louis
An EPA-registered sanitizing treatment, fogged through your ductwork after it is cleaned to neutralize the odors, bacteria and viruses a vacuum alone leaves behind. Add it to a full air duct clean and save 75% off the Virucide per opening, with the price confirmed upfront before any work begins.
What sanitizing adds
What sanitizing adds to a clean
A standard clean removes the dust and debris you can measure. Sanitizing is the extra step that treats what you cannot vacuum out: the odors, bacteria and viruses left behind in the system.
After we remove the buildup with negative-pressure, source-removal equipment, we fog a fine, EPA-registered sanitizing mist through the system with a ULV (ultra-low-volume) fogger. Registered with the U.S. Environmental Protection Agency as a virucide, it coats the inside of the ductwork to knock down odors, bacteria and viruses at the source, rather than simply pushing them around your home.
Sanitizing works best straight after a full air duct cleaning, while the system is freshly cleared. Right now it is 75% off per opening when you add it to a full clean, priced upfront before any work begins.
Add it when
When homeowners add sanitizing
Cleaning handles the dust. Adding the EPA-registered sanitizing and Virucide treatment on top makes sense in a few situations, from pets and allergies to lingering odors, recent illness, or a home that has had water damage, a leak or pests.
Allergy or asthma sufferers
For sensitive lungs, adding an EPA-registered sanitizer after the clean helps neutralize the lingering bacteria and viruses a clean alone leaves behind.
Musty or smoke odors
Our EPA-registered Virucide is designed to neutralize odors at the source, including musty smells, cigarette smoke and nicotine, rather than just masking them.
After mold treatment
Sanitizing pairs naturally with our air duct mold treatment to help keep the system fresh once the mold has been dealt with.
Recent illness in the home
After a bout of illness, many homeowners add the Virucide to help neutralize the bacteria and viruses moving through the ducts.
A new baby or older relative
When the household includes someone more vulnerable, an EPA-registered sanitizing treatment is an easy extra step toward cleaner, fresher air.
The process
How duct sanitizing works
It is a simple add-on to your clean, done in three steps on the same visit.
1
Full source-removal clean first
First we clean the whole system with negative-pressure, source-removal equipment, so the treatment goes onto clean ductwork rather than a layer of dust.
2
Fog the EPA-registered Virucide
We cover your registers, then fog a fine, EPA-registered sanitizing mist into the system with a ULV fogger, matching the output to the size of your ducts so the whole run is coated.
3
Circulate, dry and restart
We run the system fan for about an hour to carry the mist through the ductwork, let it dry, then restart. Your air comes out fresher, with the odors and microbes a clean alone could not reach knocked down at the source.

Good to know
Air duct sanitizing questions, answered
Yes. We use a water-based, EPA-registered sanitizing solution and fog it inside the duct system after the ducts are cleaned, with your registers covered so it stays in the ductwork. If anyone in your home has specific sensitivities, just let your technician know and they will walk you through the treatment before any work begins.
No, it is an optional add-on. A full air duct cleaning removes the dust and debris on its own. Many homeowners add the sanitizing and Virucide treatment for extra peace of mind, especially with pets, allergies, lingering odors or after illness, and it is priced upfront before any work begins.
Virucide is the EPA-registered sanitizing solution we fog through your ductwork after it is cleaned. It is registered with the U.S. Environmental Protection Agency as effective against bacteria and viruses, and is designed to neutralize the odors and microbes left in the system rather than just masking them.
It is designed to neutralize odors at the source in your ductwork, including musty smells, cigarette smoke and nicotine, rather than covering them with a fragrance. For the best result we apply it straight after a full air duct clean, while the system is freshly cleared.
There is no fixed schedule. Many homeowners add it every few years alongside a cleaning, or sooner if the home has had water damage, a leak, a pest problem, or lingering odors with no obvious cause. Your technician can tell you whether it is worth adding on the day.
