Health Risks from Biological Odors
Breathing and Allergy Problems
Biological odors release microbial volatile organic compounds (mVOCs) and mold spores, which can cause symptoms like headaches, nasal and throat irritation, dizziness, fatigue, and nausea. According to the Environmental Protection Agency, indoor VOC levels can be up to 10 times higher than outdoor levels. This makes indoor environments especially challenging for people with respiratory conditions. Dampness and mold are strongly linked to respiratory and allergic health issues, with studies showing these conditions are present in 18% to 50% of buildings across the United States. For individuals with asthma, these odors are particularly concerning, as they can trigger new cases or worsen existing symptoms.
Here’s a quick overview of health effects tied to exposure:
| Health Effect | Association with Dampness/Mold |
|---|---|
| Asthma development | Increased risk |
| Asthma exacerbation | Increased risk |
| Cough | Increased incidence |
| Wheeze | Increased incidence |
| Upper respiratory tract symptoms | Increased incidence |
| Allergic rhinitis | Increased risk |
| Eczema | Increased risk |
Interestingly, even just perceiving a harmful odor can affect airway function and worsen asthma, as highlighted by Cristina Jaén from the Monell Chemical Senses Center. A controlled study showed that removing sources of dampness and visible mold in homes with severely asthmatic children led to a 90% reduction in acute care visits within 6–12 months after the intervention (p = 0.003).
While these effects are serious, certain groups are even more vulnerable to the dangers of biological odors.
Risks for Sensitive People
Children, the elderly, and pregnant women are particularly vulnerable to diseases caused by air pollution. High-risk groups also include individuals with chronic respiratory issues like asthma or allergies and those with weakened immune systems, such as patients with HIV/AIDS, individuals undergoing chemotherapy, or organ transplant recipients.
Indoor air pollution has a major impact on public health, contributing to an estimated 3.2 million deaths annually. Vulnerable populations bear the brunt of these effects, especially since Americans spend about 90% of their time indoors. Health problems can appear immediately after exposure or develop over time, potentially leading to conditions like respiratory diseases, heart disease, or even cancer.
To minimize risks, address water damage within 24 hours to stop mold and bacterial growth. Once established, these microorganisms continue to release harmful compounds, putting sensitive individuals at ongoing risk. If you suspect that mold or biological odors are affecting your health, especially for those with specific medical concerns, it’s critical to consult a doctor.
What Ozone Can and Cannot Do
Methods for Removing Biological Odors
Biological odors can be stubborn and unpleasant, but there are ways to tackle them, from simple DIY remedies to more advanced professional methods. The right approach depends on how severe the odor is and its source.
DIY Solutions for Small Odor Problems
For less severe odors, like those from spoiled food or trash bins, you can try a few easy household solutions. These methods work best when the smell is confined to a specific area and the source is identifiable.
- Baking Soda: Known for its odor-neutralizing properties, baking soda is a versatile option. Mix 1 cup of baking soda with 10–15 drops of essential oil, place it in a jar, and set it in closets, restrooms, or near trash cans. You can also sprinkle it over carpets or upholstery, let it sit for a few hours, and then vacuum it up thoroughly.
- Activated Charcoal: This is another effective odor absorber. Place activated charcoal in a breathable fabric bag and put it in places like refrigerators, shoe cabinets, or musty closets. Replace the charcoal every couple of weeks to keep it effective.
- White Vinegar: With its odor-neutralizing and antibacterial qualities, white vinegar is a great option. Mix equal parts water and vinegar in a spray bottle, and lightly spray it on carpets or upholstery. For stronger smells, you can leave bowls of vinegar in the room, ensuring proper ventilation.
If these DIY methods don’t solve the problem, it may be time to consider professional treatments.
Professional Treatment Methods
For persistent or severe odors, professional treatments provide a more thorough solution. These services use advanced technologies to eliminate odors at their source rather than just covering them up.
Ozone Technology
Ozone treatment involves creating ozone molecules using either corona discharge or ultraviolet light. According to David Hart of RamAir International:
"Ozone reacts with odor molecules by transferring the ‘extra’ oxygen atom of the ozone molecule to the odor molecule, changing its composition so it no longer has the same chemical makeup. This chemical reaction is called oxidation."
While ozone is highly effective at breaking down odors, it has a short half-life of about 30 minutes and can be hazardous to humans and pets. As a result, ozone treatment is only safe for unoccupied spaces.
Hydroxyl Technology
Hydroxyl generators offer a safer alternative to ozone. These devices draw moisture from the air and pass it over a UVC light coated with titanium dioxide, creating hydroxyl radicals that break down odor-causing molecules. Tom McArdle from Odorox explains:
"Hydroxyls are the second strongest oxidant in the world behind atomic fluorine. They are one million times more reactive than ozone, which means they break down a much broader range of odors and pathogens compared to ozone."
Unlike ozone, hydroxyl generators are safe for use in occupied spaces, making them a more flexible option.
| Technology | Reactivity | Safety | Effectiveness | Occupancy During Treatment |
|---|---|---|---|---|
| Ozone | High | Harmful to humans and pets | Fast odor elimination | Unoccupied spaces only |
| Hydroxyl | 1 million times more reactive | Safe for people and pets | Broader range of odors | Occupied spaces allowed |
Professional odor removal services often combine these technologies with other methods, such as enzyme digesters, air purifiers, and HEPA filters, to ensure complete and long-lasting deodorization.
When to Hire Professional Services
Sometimes, odors are too persistent or widespread for DIY methods to handle. This is especially true for complex sources, like smoke trapped in walls, musty mold, or odors from biohazards such as sewage backups or dead animals. In these cases, professional help is essential.
Specialized equipment like ozone machines, hydroxyl generators, and HEPA air scrubbers can tackle even the toughest smells. For example, companies like Ozonated Cleaning LLC use FDA-approved treatments to locate and eliminate hidden odor sources in homes, businesses, vehicles, and even boats.
You should consider professional services when DIY efforts fail, when dealing with damage from fire or flooding, or when odors stem from biohazardous materials. Professionals not only eliminate the immediate problem but also help prevent odors from returning.

Preventing Biological Odors from Coming Back
Once you’ve tackled and removed odors, the next step is making sure they don’t return. This means managing moisture levels and staying on top of regular cleaning. These two factors are key to keeping odors at bay for good.
Managing Moisture and Humidity
Moisture is a major culprit when it comes to odors. It creates the perfect environment for microorganisms to thrive. As Capital Forest Products highlights:
"Effective moisture management is a critical aspect of maintaining a healthy, durable, and energy-efficient indoor environment. Neglecting this important issue can have severe consequences, including structural damage, mold growth, compromised indoor air quality, and potential health risks for building occupants."
Here’s something to think about – a family of four can produce around four gallons of moisture every single day. And moisture-related problems are no small issue: 75–80% of building envelope issues stem from moisture, and studies show that 38% of detached homes and 25% of apartments deal with notable moisture problems.
Keep Humidity Levels in Check
Aim to maintain indoor humidity between 30% and 50%. The American Society of Heating and Air Conditioning Engineers (ASHRAE) offers these guidelines based on outdoor temperatures:
| Outdoor Temperature | Recommended Indoor Humidity |
|---|---|
| +20°F | 35% |
| +10°F | 30% |
| 0°F | 25% |
| -10°F | 20% |
| -20°F | 15% |
Use a humidity indicator to monitor levels in your home. In particularly humid areas, like basements, or during humid seasons, dehumidifiers can make a big difference. Just make sure to maintain them properly to avoid turning them into a source of pollutants themselves.
Address Water Issues Immediately
Don’t wait to fix water leaks – handle them as soon as they appear. Check that the ground around your home slopes away from the foundation to keep water out of your basement. For crawl spaces, cover dirt floors with plastic sheeting and ensure these areas are well-ventilated.
Boost Ventilation and Airflow
Exhaust fans are your friend, especially in moisture-heavy areas like bathrooms and kitchens. Use them while cooking or showering, and keep bathroom fans running for about 20 minutes before and after showers to reduce the risk of mold growth. Improve airflow by using fans and moving furniture away from walls where condensation tends to collect. Insulating cold surfaces and installing storm windows can also help minimize condensation.
Be Mindful of Flooring in Damp Areas
Avoid installing carpet directly on concrete floors, as this can trap moisture. If you do need carpeting, use a vapor barrier and sub-flooring underneath. Alternatively, opt for area rugs that can be easily cleaned and dried. In damp spaces like basements, use moisture-absorbing products and ensure proper ventilation to prevent musty smells.
Combine these moisture-control measures with regular cleaning to keep odors from making a comeback.
Regular Cleaning and Maintenance
Moisture isn’t the only factor – routine cleaning plays a big role in tackling the organic residues that fuel odor-causing bacteria. As Second Nature explains:
"Instead of deodorizing a room using air fresheners that release chemicals into the air and only mask odors, we want to remove odors at the source."
Pay close attention to high-touch and moisture-prone areas. Replace cleaning tools often and change HVAC filters regularly to prevent organic buildup. Kitchens and bathrooms are hotspots for odors, so focus on cleaning appliances like refrigerators, dishwashers, and garbage disposals. Don’t forget to wash garbage cans regularly with a mix of white vinegar and water.
Replace sponges monthly and clean reusable cleaning cloths weekly to avoid bacteria buildup. Stay on top of laundry to prevent odors in fabrics, and keep pets clean with regular grooming and bathing.
Tweak Your Daily Routines
Small changes in your daily habits can make a big difference in reducing moisture. Cover pots while cooking, take shorter and cooler showers, and always ensure proper ventilation during these activities. These adjustments go a long way in preventing the conditions that lead to biological odors.
If odors persist despite your best efforts, it might be time to call in the professionals.

FAQs
What health risks do biological odors pose, especially for children and the elderly?
Biological odors, often stemming from pollutants like mold, bacteria, and allergens, aren’t just unpleasant – they can seriously impact health, especially for vulnerable groups like children and older adults. These odors can aggravate respiratory issues, worsen asthma, and even trigger allergic reactions. For children and seniors, extended exposure to poor indoor air quality can lead to more severe problems, including a higher risk of infections and potential cognitive decline.
Children and the elderly are particularly at risk because their immune systems may not handle these pollutants as effectively. On top of that, many older adults have a reduced sense of smell, which can prevent them from detecting hazards like gas leaks or spoiled food, increasing the chance of dangerous situations. Tackling these odors quickly is crucial to ensure a safe and healthy living space.
What’s the difference between ozone and hydroxyl technologies for removing indoor odors?
Ozone and hydroxyl technologies are both powerful tools for tackling odors, but they differ significantly in how they operate and their safety profiles.
Ozone works fast, breaking down odors almost immediately. However, it comes with a major drawback – it can be harmful if inhaled by humans or pets. Because of this, spaces undergoing ozone treatment must be completely unoccupied. In fact, its use is regulated in some areas due to the potential health risks associated with exposure.
Hydroxyl technology, in contrast, is safe for use in spaces where people and pets are present. While it works more gradually than ozone, it effectively eliminates odors over time and even helps improve air quality. This makes it a great choice for homes, offices, and other environments needing continuous odor control. While ozone delivers quick results, hydroxyl technology stands out as a safer and more practical solution for long-term use.
How can I prevent biological odors from coming back after removal?
To keep unpleasant biological odors at bay, start with proper ventilation. Open your windows regularly to let in fresh air and consider adding air purifiers to improve circulation. Keeping moisture levels under control is equally important. Use dehumidifiers in damp areas and address leaks promptly to avoid mold and mildew, which are often the culprits behind persistent smells.
Regular cleaning plays a huge role too. Tackle spills, pet accidents, and messes as soon as they happen, and pay extra attention to high-traffic areas like kitchens and bathrooms. Keeping these spaces clean and dry can make a big difference. For extra odor-fighting power, try specialized cleaning products designed to neutralize smells. By staying consistent with these steps, you can enjoy a fresher, more pleasant environment.
