Wildfire Smoke in Northeast Florida How to Protect Your Home’s Indoor Air Quality
If you have stepped outside anywhere in Duval, Clay, Nassau, or St. Johns County this week, you have likely noticed a haze in the air, the faint smell of smoke, and skies that look a little different than usual.
Northeast Florida is currently experiencing one of the most active wildfire seasons in decades. As of this week, crews are battling multiple active wildfires across our region including a 4,100-acre Railroad Fire burning along the Clay-Putnam County line, fires in Nassau County, and dry, windy conditions that officials warn could fuel continued fire activity for the next eight to ten weeks. Jacksonville Mayor Donna Deegan has issued a total burn ban across Duval County, and St. Johns, Clay, and Nassau counties are all operating under burn bans as well.
The brave men and women fighting these fires have our full respect and gratitude. This blog is not about alarm; the fires are not threatening most residential areas directly at this time. This is about something quieter and less visible: what wildfire smoke does to the air inside your home, and what you can do right now to protect your family’s health and comfort during an extended period of elevated outdoor air pollution.
What Wildfire Smoke Actually Does to Your Home’s Indoor Air
Most Northeast Florida homeowners assume that keeping windows closed and running the AC provides adequate protection from outdoor smoke and pollution. The reality is more nuanced and understanding it helps you make informed decisions about protecting your household.
Wildfire smoke is not simply visible haze. It is a complex mixture of fine particulate matter known as PM2.5 along with volatile organic compounds (VOCs), carbon monoxide, nitrogen oxides, and other combustion byproducts. The particles classified as PM2.5 are particularly concerning because they are smaller than 2.5 micrometers small enough to penetrate deep into the lungs and, in higher concentrations, enter the bloodstream.
According to the EPA’s Wildfires and Indoor Air Quality guidance, wildfire smoke enters homes through multiple pathways even when windows and doors are closed through small gaps and cracks in building envelopes, around door and window frames, and through HVAC fresh air intakes. The EPA notes that indoor air quality during a smoke event depends significantly on how well-sealed a home is and what type of air filtration is in place.
The same EPA research consistently finds that indoor air can be two to five times more polluted than outdoor air in normal conditions and during an active smoke event without proper filtration, that gap can narrow in the wrong direction as smoke infiltrates indoor spaces.
“Keeping your windows closed and your AC running is a good first step during a wildfire smoke event. But it is not the complete solution. The right filtration inside your HVAC system is what genuinely protects the air your family breathes.”
Who Is at Higher Risk During Wildfire Smoke Events in Northeast Florida
We want to be clear: elevated wildfire smoke is a concern for everyone but most healthy adults experience only mild irritation during typical smoke events. However, certain groups in our community face meaningfully higher health risks from prolonged exposure to wildfire smoke particulates, and those households should take indoor air quality particularly seriously right now.
Children
Children’s respiratory systems are still developing and their breathing rates are higher relative to body size than adults meaning they inhale more air, and more of any particles in that air, per pound of body weight. Children with pre-existing respiratory conditions are at elevated risk, but even healthy children can be affected by sustained exposure to PM2.5 particulates at elevated levels.
Adults With Asthma
For the estimated 1 in 13 Americans living with asthma, wildfire smoke is a well-documented trigger for increased symptoms and attacks. Fine smoke particles can cause airway inflammation and bronchospasm even at outdoor air quality levels that appear moderate on standard indices. If anyone in your Northeast Florida household has asthma, this is the time to ensure your indoor air is as clean as possible.
Adults With COPD or Other Chronic Respiratory Conditions
Chronic obstructive pulmonary disease, chronic bronchitis, and similar conditions make individuals significantly more vulnerable to particulate matter exposure. During active wildfire events, individuals with these conditions may experience worsened symptoms even while remaining indoors in what feels like a normal environment.
Elderly Residents
Age-related changes in respiratory function and immune response make older adults more susceptible to the effects of elevated air pollution. Many elderly residents in Duval, St. Johns, Clay, and Nassau counties spend the majority of their time indoors making the quality of that indoor air particularly important during extended smoke events.
Pregnant Women
Research indicates that exposure to fine particulate matter during pregnancy is associated with adverse outcomes. While current wildfire smoke levels in most of Northeast Florida do not represent a severe acute risk for healthy pregnant women, maintaining clean indoor air is a reasonable and straightforward precaution.
Pets
Dogs and cats are also affected by poor indoor air quality during smoke events. Pets with existing respiratory conditions, flat-faced breeds, and elderly animals are particularly vulnerable. If your pet is coughing, wheezing, or showing lethargy during this period of elevated smoke, improving your indoor air quality can help.
What Is an Air Scrubber And How Does It Help During a Smoke Event
An air scrubber is a whole-home air purification system that installs directly into your existing HVAC ductwork typically near the air handler. Unlike a portable air purifier that cleans a single room, an air scrubber works with your HVAC system to treat the air in every room of your home simultaneously, every time the system runs.
Here is how it works in the context of wildfire smoke protection:
What an Air Scrubber Removes
A quality air scrubber integrated with your HVAC system addresses the specific components of wildfire smoke that standard filters cannot fully handle:
- Fine particulate matter (PM2.5) the microscopic smoke particles that penetrate deepest into the respiratory system and are the primary health concern during wildfire events
- Volatile organic compounds (VOCs) chemical gases released during combustion including benzene, formaldehyde, and acrolein that linger in indoor air long after the visible smoke has cleared
- Smoke odour by neutralising odour-causing molecules at their source rather than masking them
- Secondary contaminants mold spores, bacteria, and allergens that are always present in Jacksonville’s humid air and compound the effects of smoke exposure on respiratory health
How It Works With Your Existing HVAC System
The air scrubber installs in your supply air plenum the ductwork section after your air handler and uses a combination of UV-C light and photocatalytic oxidation technology to neutralise contaminants as air passes through. Rather than simply filtering particles like a standard filter, this technology actively breaks down pollutants at a molecular level. The system operates automatically whenever your HVAC system runs and requires minimal maintenance beyond an annual UV bulb replacement.
The Difference Between an Air Scrubber and a Better Filter
Upgrading to a MERV 13 filter in your existing HVAC system is a good step during a smoke event and one we recommend doing right now regardless. The EPA recommends a MERV 13 filter as a minimum standard during wildfire smoke events for homes with central HVAC systems. However a better filter alone does not address VOCs and gaseous combustion byproducts; it only captures particles. An air scrubber addresses both the particulate and the gaseous components of smoke, providing more comprehensive protection.
What You Can Do Right Now A Practical Indoor Air Quality Checklist
Whether or not you decide to install an air scrubber, here are practical steps every Northeast Florida homeowner can take immediately during the current wildfire smoke period:
- Keep windows and doors closed while outdoor smoke levels are elevated. Check the National Weather Service Jacksonville and local news for daily air quality updates.
- Upgrade your HVAC filter to MERV 13 if your system can accommodate it. Check with Bold City or consult your system manual to confirm compatibility. A filter that is too restrictive for your system can reduce airflow and strain the equipment.
- Change your filter more frequently during active smoke periods. A filter that normally lasts 30 days may need replacement every 1 to 2 weeks during sustained smoke events.
- Set your HVAC fan to “ON” rather than “AUTO” to continuously circulate and filter indoor air even when the system is not actively heating or cooling.
- Check and seal gaps around windows, doors, and any known air infiltration points in your home’s envelope particularly in older homes across Duval County where weatherstripping may have degraded.
- Avoid adding indoor pollutants during this period candles, incense, frying at high temperatures, and gas cooking all add combustion byproducts to indoor air that compound the effects of outdoor smoke infiltration.
- Monitor vulnerable household members closely anyone with asthma, COPD, or respiratory sensitivities should have their rescue medications readily available and should contact a healthcare provider if symptoms worsen.
Is an Air Scrubber a Long-Term Investment or Just for Smoke Events?
This is an important question and one we want to answer honestly. An air scrubber is genuinely a year-round investment in your home’s indoor air quality, not just a wildfire response tool.
In Northeast Florida’s climate with year-round humidity, heavy spring pollen seasons, mold risks in our warm wet environment, and an HVAC system that runs almost continuously the benefits of an air scrubber extend well beyond smoke events. Homeowners across Duval, St. Johns, Clay, and Nassau counties who install air scrubbers consistently report improved air quality, reduced allergy symptoms, less dust accumulation on surfaces, and fresher-smelling indoor air year-round.
The current wildfire situation is a timely reminder of why indoor air quality matters but the investment you make in your home’s air quality today will continue returning value through every pollen season, every humid summer month, and every future air quality event our region experiences.
Florida Forest Service Director Rick Dolan has noted publicly this week that the peak of Florida’s fire season is still ahead and with eight to ten more weeks of elevated wildfire risk forecast for our region, there has genuinely never been a better time to consider this upgrade for your Northeast Florida home.

Frequently Asked Questions: Wildfire Smoke and Indoor Air Quality in Northeast Florida
Is the wildfire smoke in Northeast Florida dangerous for my family right now?
Current wildfire smoke levels across most of Duval, St. Johns, Clay, and Nassau counties present a low to moderate concern for healthy adults. However, individuals with asthma, COPD, other respiratory conditions, children, elderly residents, and pregnant women should take additional precautions. Keep windows and doors closed, upgrade your HVAC filter, and monitor local air quality advisories through the National Weather Service Jacksonville and local news sources. If anyone in your household experiences worsening respiratory symptoms, contact a healthcare provider.
Will my regular AC filter protect me from wildfire smoke particles?
A standard 1-inch fiberglass filter (MERV 4-6) offers limited protection against the fine PM2.5 particles in wildfire smoke. The EPA recommends upgrading to a MERV 13 filter as a minimum standard during smoke events. However even a MERV 13 filter does not address volatile organic compounds and gaseous combustion byproducts for comprehensive protection, an air scrubber integrated with your HVAC system is the most effective solution. Call Bold City at 904-379-1648 before upgrading your filter to confirm your system can accommodate a higher MERV rating without restricting airflow.
How long does it take to install an air scrubber?
A whole-home air scrubber typically installs in two to three hours. The system mounts inside your existing HVAC ductwork near the air handler with no major modification to your system required. Bold City Heating & Air provides same-week installation appointments across Northeast Florida call 904-379-1648 to check current availability.
How long will the wildfire smoke situation last in Northeast Florida?
Florida Forest Service Director Rick Dolan warned publicly this week that conditions are among the driest in a quarter-century and that officials are bracing for eight to ten more weeks of elevated wildfire activity. With peak fire season typically driven by lightning strikes still ahead, Northeast Florida homeowners should plan for an extended period of elevated outdoor air quality concerns through late spring and into summer.
Does an air scrubber work for regular Jacksonville air quality issues too, not just wildfires?
Yes and this is one of the most important things to understand about this investment. An air scrubber provides year-round benefits in Northeast Florida’s climate including reduced pollen and allergen levels during spring allergy season, mold spore reduction in our humid environment, elimination of VOCs from household products, and improved overall indoor air freshness. The wildfire situation is a compelling reason to act now, but the benefits continue long after the fires are contained.
