INDOOR AIR QUALITY & VIRAL PARTICLES
COVID-19 Can Spread Through the Air Inside Your Home
COVID-19 is primarily spread through respiratory droplets and airborne particles. In enclosed spaces, those particles can remain in the air and move through shared rooms, especially when ventilation and filtration are poor.
Airborne Particles
Respiratory particles can linger in indoor air after coughing, sneezing, talking, or breathing
Shared Indoor Spaces
Poor ventilation can allow particles to build up in rooms where people gather
HVAC Circulation
Air moving through the home can carry dust, allergens, and airborne contaminants
Respiratory Health Concern
COVID-19 can cause serious illness, especially for higher-risk individuals
Improve Indoor Air Quality
And Reduce Airborne Contaminants
COVID-19 is most commonly associated with exposure to respiratory particles released when an infected person breathes, talks, coughs, or sneezes. Indoors, those particles can become more concentrated when fresh air and filtration are limited.
While no air system can guarantee protection from illness, improving indoor air quality can help reduce airborne contaminants and create a healthier home environment.
Green Home Air helps homeowners address indoor air quality concerns connected to dust, allergens, microbial buildup, and airborne particles that may circulate through the home.
A cleaner HVAC system, better filtration, and improved air movement can support a healthier indoor environment for your family.
Important Safety Note:
- Improve ventilation when possible
- Use quality HVAC filtration
- Replace dirty filters regularly
- Keep indoor air moving and filtered
- Clean high-touch areas as needed
Why Act Now
COVID-19 Can Spread Through Indoor Air.
COVID-19 spreads when an infected person releases respiratory droplets and small airborne particles while breathing, talking, coughing, or sneezing. In enclosed spaces with poor ventilation, those particles can build up and increase exposure risk indoors.

Local Expertise
COVID Decontamination in St. George
The St. George Picture
St. George has a large retiree population, a busy tourism and short-term rental market, and the medical facilities that serve both. Those are exactly the settings where turnover is high, the people passing through may be vulnerable, and documented decontamination genuinely matters.
The decontamination work we do in Washington County reflects who lives and travels here. St. George has a substantial retiree population, along with the clinics, senior living facilities, and community centers that serve them, and those are environments where infection carries higher risk.
The tourism economy adds a second demand, since vacation rentals and hospitality spaces turn over constantly and operators need both effective treatment and something they can show guests. We work around turnovers and after hours, and every commercial job comes with documentation of the areas treated, the date, and the products used.
Lodging and visitor traffic
Zion National Park recorded 4,984,525 recreation visits in 2025, according to National Park Service figures. Visitor traffic is a large part of life in southern Utah, and St. George has hotels, offices, gyms and event spaces that serve both residents and visitors. Busy shared spaces are where routine disinfection makes the most sense.
For commercial clients, we focus on high-touch surfaces in lobbies, restrooms, break rooms and front desks. We use electrostatic sprayers so disinfectant reaches the sides and undersides of surfaces, not just the tops. We can work after hours so your business stays open.
Before we start, we ask what the space is used for and who uses it. A restroom gets different attention than a conference room, and electronics need a product and method that will not damage them. We cover or move items that should not get wet. When we finish, we tell you when people can use each room again and leave a list of what was treated.
Products and contact time
We use EPA-registered disinfectants. EPA explains that each product has a contact time, which is how long a surface has to stay wet for the product to work. Wiping too soon is a common reason disinfection falls short. SARS-CoV-2, the virus that causes COVID-19, is an enveloped virus, which EPA places in its Tier 1 group.
St. George summers are hot and dry, with July highs averaging 102 degrees. Thin coatings can dry faster than the label time on warm surfaces. We watch for that and reapply when a surface dries early, especially in rooms near west-facing windows or in spaces without air conditioning, such as garages and storage areas.
Homes with someone at higher risk
The Census Bureau estimates that 21.8 percent of St. George residents are 65 or older. Some families want a home disinfected after an illness, before an older relative or a new baby visits. That is a practical, low-key request, and we treat it that way.
We focus on the rooms the sick person used and the surfaces people touch most. We tell you which products we used and when the rooms are ready to use again. For health questions, the Southwest Utah Public Health Department and your doctor are the right sources.
FAQs
Frequently Asked Questions
Can you work around short-term rental turnovers in St. George?
Yes, and it is a routine part of what we do here given the size of the vacation rental market. Treatment for a typical property is completed within hours, and the space is ready once surfaces have dried and it has ventilated. We schedule around turnover windows and work after hours so that a property is not sitting empty longer than necessary between guests.
Do senior living facilities in St. George need different handling?
The protocol is similar but the standard of care and the documentation matter more, because the residents are a higher-risk population. We work closely with facility staff on scheduling around residents, focus on the high-touch points in shared and common areas, and provide full documentation of what was treated and when, which these facilities generally need for their own records and to share with families.
What affects the cost of disinfection for a St. George business?
Cost depends on square footage, the number of rooms and restrooms, how many high-touch surfaces there are and whether the work happens after hours. A small downtown office is quicker than a gym or event space with equipment and locker rooms. Recurring service is planned differently from a one-time cleaning. We walk the space or review a floor plan before we quote.
Is there a busier time of year for disinfection requests in St. George?
Requests tend to follow respiratory illness, which usually circulates more in the cooler months. Businesses that serve visitors may also want service before or after their busiest weeks. With Zion drawing nearly five million visits in 2025, lodging and visitor businesses often want service timed around their own peak weeks. We plan around your calendar rather than a set schedule.
Will insurance cover disinfection or do I need paperwork for it?
Routine disinfection is usually an operating expense, not an insurance claim. Coverage for a specific event depends on your policy, so check it and ask your agent. Many St. George businesses simply want a record. We provide the date, the areas treated and the EPA registration numbers of the products used, which is useful for your files or for a landlord who asks.
Which disinfectants do you use in St. George homes and businesses?
We use EPA-registered disinfectants and follow each label, including its contact time. EPA keeps lists of products tested against specific viruses, including SARS-CoV-2. We can tell you which product we plan to use and why. If anyone in the building has chemical sensitivities, let us know ahead of time so we can talk through options and timing.
Can you disinfect my St. George home after a family member was sick?
Yes. We focus on the rooms the sick person used, the bathroom they used and the surfaces everyone touches, like doorknobs, remotes and counters. Wash bedding and clothes yourself in the normal laundry. We tell you when treated rooms are ready to use. Disinfection lowers what is on surfaces, but it does not replace your doctor's advice about illness.
Do you serve churches, clinics and other shared spaces around St. George?
Yes. We serve commercial and community spaces in St. George and across Washington County, including meeting halls, waiting rooms, classrooms and offices. We can work between services, after hours or on a weekday when the building is closed. For spaces where many older adults gather, we pay extra attention to handrails, restroom fixtures and seating.
