Ozone for Mold Elimination

Mold in buildings is more than an aesthetic issue—it's a serious health and structural concern that affects homes, businesses, and institutions alike. When left untreated, mold can damage building materials and degrade indoor air quality, ultimately posing risks to human health.

 

 
Why Mold Is a Problem:
Mold grows in damp, humid conditions and thrives on organic materials like wood, drywall, and insulation. Once established, it releases spores into the air. These spores can carry mycotoxins and other bioaerosols, which are harmful to occupants when inhaled or touched.
 

Health Risks of Mold Exposure:

- Respiratory issues: coughing, wheezing, asthma aggravation

- Allergic reactions: itchy eyes, runny nose, skin irritation

- Long-term exposure risks: chronic sinus infections, fatigue, neurological symptoms

- High-risk groups: children, elderly, immunocompromised individuals

Structural and Financial Impacts:

- Mold weakens building materials like drywall, wood framing, and ceiling tiles

- Long-term infestations can result in expensive repairs and remodeling

- Hidden mold behind walls or under flooring can go undetected for years

 
Common Causes of Mold Growth:

- Leaky roofs, windows, or plumbing

- Poor ventilation in bathrooms, basements, and kitchens

- Flooding or water damage not properly dried

- High indoor humidity levels

 

Traditional Remediation Approaches:

- Physical removal of contaminated materials

- Use of biocides and chemical treatments

- Improved ventilation and moisture control

While these methods are effective to some extent, they often fail to reach mold hidden within walls or under floors. Chemical treatments may also pose health risks of their own, especially with repeated exposure.

 
A Safer, More Effective Alternative:

Ozone Treatment: Ozone gas, when applied properly, can reach into cracks and crevices that physical cleaning cannot. It works by oxidizing mold spores, rendering them inactive. Additionally, ozone naturally decomposes back into oxygen, leaving no chemical residue.

 

Below are specific case studies and research showcasing the use of ozone in mold removal.

 

 

The Practical Application of Ozone Gas as an Anti-fungal (Anti-mold) Agent

Abstract

We evaluated the ability of a portable ozone generating machine (Viroforce 1000) to inactivate 13 different species of environmental fungi. Samples, prepared as wet or dried films, were subjected to one or two cycles of treatment (35 ppm ozone for 20 minutes, with a short burst of >90% relative humidity), and measured for residual viability. Treatments could inactivate 3 log10 cfu (colony forming units) of most of the fungi, both in the laboratory and in simulated field conditions, on various surfaces. We conclude that the ozone generator would be a valuable decontamination tool for mold removal in buildings.
