The proliferation of mold is a prevalent issue encountered in numerous households and commercial establishments alike. Excess moisture from leaks, flooding, or high humidity causes mold to grow on surfaces. Mold releases spores that cause allergic reactions, asthma attacks, and other health issues. Removing mold entirely requires killing the roots and spores. Ozone is an emerging method some people use to try to fully eradicate mold.

However, ozone gas is hazardous at high concentrations. Short-term exposure aggravates respiratory conditions like asthma. Long-term exposure causes reduced lung function and lung tissue inflammation. The EPA warns that ozone generators sold for home use often produce unsafe ozone levels. Operating ozone generators requires following safety precautions.

Using ozone on mold

Ozone has gained popularity as a way to fully eradicate mold, without using harsh chemicals. Here’s a look at its effectiveness on mold.

  • Kills mold – Ozone is a strong antimicrobial that destroys mold. In sufficient concentrations, it kills mold spores and mycotoxins. Ozone damages proteins and breaks down molecules in mold cells.
  • Penetrates porous materials – As a gas, ozone penetrates porous materials like drywall and wood. This allows it to reach mold growing inside these materials. Liquids or foggers have difficulty reaching mold within porous materials.
  • No chemical residue – Ozone naturally converts back into oxygen, leaving no chemical residues. This makes it safe for use around food, children’s toys, and other sensitive items.
  • Removes odors – By oxidizing the compounds that cause odors, ozone dissipates musty mildew smells. This helps remove the moldy odor, even after mold removal.

Integrating ozone into mold remediation

  1. Identify and repair all moisture problems allowing mold growth. This is the most critical step, without which mold will recur.
  2. Use protective gear to remove contaminated porous materials like drywall and insulation. Dispose of it properly.
  3. Clean all remaining hard surfaces with detergent or other cleaners to remove mold residue.
  4. Run the ozone generator to kill the remaining mold spores and mycotoxins. Follow all safety precautions.
  5. Ventilate thoroughly and allow the ozone to dissipate completely back into oxygen.
  6. Apply mold-resistant paints or bleach solutions to treated areas as an added protective barrier.
  7. Properly dry out any remaining moisture using dehumidifiers or other drying methods.
  8. Continue monitoring the area and immediately address any new moisture issues.

Ozone works best alongside conventional remediation techniques, not as a stand-alone fix. Address the source of moisture allowing the mold growth in the first place. Then ozone helps ensure mold roots and spores are killed anywhere they’ve spread in a porous material. Integrating Damage Control-911 helps provide a comprehensive solution to mold problems.

Ozone is an emerging tool some mold remediation companies use to help fully eradicate mold. Proper safety precautions are necessary due to the potential health hazards of ozone gas. When integrated into a comprehensive mold removal protocol, ozone can enhance efforts to kill mold spores and prevent mold from recurring. However, fixing excess moisture issues remains the keystone for successful mold remediation in any home or business.
