Sanitize Everything With Ozone
Ozone Cleaning Basics
This section breaks down the science and process of ozone cleaning, focusing on how oxidation works to neutralize contaminants.
How Ozone Molecules Work
Ozone (O₃) consists of three oxygen atoms, making it a powerful oxidizer. When an ozone molecule comes into contact with bacteria, viruses, or odor-causing compounds, its extra oxygen atom detaches, oxidizing and neutralizing them. Afterward, ozone naturally reverts to regular oxygen, leaving no residue.
In water treatment, ozone eliminates bacteria 3,125 times faster than chlorine.
Step-by-Step Treatment Process
Here’s how the ozone cleaning process works:
-
Pre-Treatment Preparation
Start by cleaning the area to remove surface dirt and debris. -
Environment Setup
Ensure the space is clear of people, pets, and plants. Keep the area dry, as ozone is more effective in low-humidity conditions. -
Treatment Application
Place ozone generators in strategic locations. Treatment durations vary based on the area size, ranging from 20 minutes for small spaces to 2.5 hours for larger ones. Key factors influencing treatment time include:Factor Impact on Treatment Room Size Larger spaces require longer treatments Ceiling Height Higher ceilings demand more ozone Air Tightness Sealed spaces retain ozone better Contamination Level Heavily contaminated areas need extended treatment -
Post-Treatment Protocol
After treatment, allow the area to ventilate until the ozone converts back to oxygen. Avoid occupying the space during this airing-out period.
Under the right conditions, ozone cleaning can eliminate up to 97% of bacteria and viruses. It’s widely used for sterilizing medical instruments and treating water systems.
Next, we’ll explore how ozone cleaning performs across different applications.
Results and Performance
Germ and Bacteria Removal
The World Health Organization states that ozone treatment, when applied correctly, can eliminate 97% of bacteria, viruses, and mold. At ozone levels above 7 ppm, it disrupts pathogens by cutting off their oxygen supply.
| Surface Type | Effectiveness |
|---|---|
| High-Touch Areas | Reaches spots that regular cleaners can’t access |
| Air Space | Cleans both surfaces and airborne contaminants |
| Porous Materials | Penetrates deep into fabrics and other materials |
| Water Systems | Removes bacteria present in water |
Let’s look at how ozone cleaning handles tough odors next.
Types of Odors Eliminated
Ozone cleaning doesn’t just cover up odors – it changes the chemical structure of the molecules causing them.
"It’s what takes away that smell. The other things are just helping. If you don’t do ozone, you still have the smell underneath the paint." – Mike Calamus, Owner of Calamus Enterprises
Here are some odors ozone cleaning can handle:
- Smoke and cigarette smells
- Pet-related odors
- Food and cooking smells
- Mold and mildew
- Marijuana
- General musty environments
This ability to address a wide range of odors makes ozone cleaning useful in many scenarios.
Where to Use Ozone Cleaning
Ozone cleaning is especially helpful in areas where traditional cleaning methods fall short.
| Setting | Primary Uses |
|---|---|
| Residential | Fire damage cleanup, mold removal, deodorizing |
| Commercial | Refreshing hotel rooms, sanitizing offices |

Safety Guidelines
During Treatment Safety Rules
The area being treated must stay completely empty during the process. This means no people, pets, or plants should be present. Remove items that could be damaged, such as artwork, rubber materials, or other sensitive objects. Place clear "NO ENTRY" signs at all entrances, and always rely on the ozone generator’s built-in timer for safe operation.
Exposure to ozone gas can lead to serious health issues, including lung damage, chest pain, coughing, shortness of breath, and throat irritation. Following these precautions is critical for safety.
Air-Out Requirements
Proper ventilation after treatment is essential to remove any leftover ozone before reentering the space. The time needed depends on the ventilation setup:
| Ventilation Type | Required Time | Method |
|---|---|---|
| Windows Available | 30 minutes | Open all windows and doors |
| No Windows | Up to 4 hours | Use the HVAC system |
| Basement Areas | 2–3 hours | Run air conditioning and ventilate through doors |
Safety Standards
Strict safety protocols are in place for ozone cleaning to ensure safe and effective use. Here are the key guidelines:
- Monitoring and Training: Always use ozone monitors to confirm safe levels before reentry. Operators must be trained and certified to handle ozone equipment safely.
- Treatment Duration: Keep exposure time limited to reduce the risk of material damage during treatment.
Ozone naturally breaks down with a half-life of about 15 minutes, quickly converting back into oxygen. If you’re considering continuous disinfection systems for occupied spaces, consult an ozone expert first. Ozone is known to be 50 times more effective at disinfection than chlorine.
Pros and Cons
Ozone cleaning comes with both benefits and challenges:
Side-by-Side Comparison
| Advantages | Limitations |
|---|---|
| 50 times more effective than chlorine for disinfection | Higher upfront equipment costs |
| Neutralizes odors by breaking down odor-causing compounds | Requires evacuation during treatment |
| Breaks down into pure oxygen, leaving no chemical residue | 2–3 hour wait time before reentry |
| On-site generation eliminates chemical storage needs | Needs ozone monitoring for safety |
| Quickly eliminates pathogens | Unsuitable for spaces with continuous occupancy |
| Approved by EPA, FDA, USDA, and OSHA |
These points highlight ozone cleaning’s effectiveness while also pointing out its practical limitations.
Experts in the field emphasize its advantages:
"Unlike chlorine, ozone leaves no harmful chlorinated by-products in the water, ozone quickly reverts back to pure oxygen if unused"
"The ozone generator will transform a foul-smelling substance into a non-odorous substance by destroying the airborne cells that produce the odor, all without the use of harmful chemicals."
Research backs these claims, showing that "Ozone oxidation reactions take place several thousand times faster than those of chlorine for destruction of bacteria, viruses, yeast, molds, cysts, mildew, and most other organic and inorganic contaminants".
Despite its efficiency, ozone cleaning requires careful monitoring, precise timing, and strict safety protocols. While the initial costs for equipment and training are higher than traditional methods, ongoing operational expenses are often reduced over time.
Knowing these benefits and drawbacks underscores the need to follow safety guidelines and treatment protocols closely.
