Will ozone kill mold? Examining the effectiveness of ozone on mold

305 0

Mold is a major problem in many homes and businesses. Prolonged mold exposure like allergies, asthma attacks, sinus congestion, and more. Mold remediation is essential but be challenging and expensive. Many people have questions about using ozone as a DIY mold treatment.

Science of ozone on mold

When evaluating ozone as a DIY mold treatment, it’s important to the science behind how it works. Ozone kills mold through oxidation, chemically destroying the mold spores and hyphae structures. Studies show ozone is effective against many types of common molds, including Aspergillus, Penicillium, and Stachybotrys (black mold).

Research also indicates that ozone degrades and destroys mycotoxins, the toxic substances produced by molds. Mycotoxins are very difficult to destroy and remain present even after mold cleanup. By neutralizing these harmful toxins, ozone provides health benefits and ensures that mold is no longer a hazard. In theory, ozone seems like an ideal DIY mold killer. However, effectively using ozone on mold in the real world comes with some challenges and risks.

Limitations of ozone on mold

When examining ozone for home mold treatment, it’s clear the gas has limitations:

  1. Limited penetration and contact– For ozone to work against mold, it must physically contact the mold source. But ozone dissipates quickly, making it difficult for the gas to penetrate and kill mold growing inside porous materials like drywall or wood damagecontrol 911.com check this link right here now
  2. Extreme reactivity– The unstable nature of ozone that makes it a strong oxidizer also causes challenges. Ozone reacts immediately upon contact and does not last long in the air. Maintaining effective ozone levels for mold remediation requires prolonged high-output generation.
  3. Health hazards– High concentrations of ozone cause breathing issues and damage the lungs. Lower levels also harm those with asthma or respiratory illness. Ozone’s health risks make DIY applications dangerous.
  4. No residual benefit– When ozone dissipates, it leaves no residual disinfectant behind. Any mold that was not in contact with the initial ozone treatment may survive and regrow. Other disinfectants like chlorine bleach have lasting antimicrobial effects.
  5. Damage to materials– Ozone degrades natural rubber, plastics like vinyl, and other common household materials. Even at low concentrations, ozone causes costly damage. Using ozone may demand wholescale replacement of affected surfaces and contents. Professional application with containment, high-output generators, and personal protective equipment is essential for ozone to be effective and minimally hazardous.

Professional ozone mold remediation

Given the challenges of DIY application, ozone is best deployed by professional mold remediation contractors. Trained specialists take precautions to use ozone safely and maximize its effectiveness against mold. Key steps in professional ozone mold remediation include:

  1. Evaluating the extent of the mold problem through testing and assessments. This determines the proper scope of ozone treatment.
  2. Isolating and sealing off the affected area. This contains the ozone to maximize concentration and prevent hazardous off-gassing to other spaces.
  3. Using commercial-grade ozone generators calibrated to optimal settings. Professional rigs ensure penetrating distribution and adequate runtimes.
  4. Monitoring ozone levels throughout the process. Sensors concentrations remain within safe ranges.

Though expensive, professional ozone mold remediation delivers the concentration, contact, and containment needed to overcome the gas’s practical limitations.
