How Ozone Works

The Science Behind Ozone Therapy for Mould & Odour Removal

What is Ozone & How Does It Work?

Ozone (O₃) is a naturally occurring gas composed of three oxygen atoms. It is a powerful oxidising agent that effectively eliminates mould, bacteria, viruses, and odours at a molecular level. Ozone therapy has been widely used in industries ranging from healthcare and water purification to mould remediation and air sanitisation.

At Masters of Mould, we harness the power of high shock ozone treatment to safely and effectively remove mould spores, musty odours, and airborne toxins—restoring your home or business to a clean, healthy environment.

The Science of Ozone for Mould Removal

When ozone is released into an affected space, it works through a process called oxidation. Here’s how it eliminates mould and odours:

Ozone molecules disperse into the air, penetrating walls, carpets, ceilings, and air conditioning systems.

Ozone reacts with mould spores, bacteria, and volatile organic compounds (VOCs), breaking them down at a molecular level.

As ozone oxidises contaminants, it destroys their cell structure, preventing regrowth and eliminating odours.

Once the treatment is complete, ozone naturally reverts back to oxygen (O₂), leaving no harmful residues—just fresh, purified air.

Unlike traditional chemical treatments that only clean surface mould, ozone therapy neutralises airborne and hidden mould spores, ensuring a deeper, longer-lasting solution.

The Benefits of Ozone Therapy

100% Chemical-Free & Eco-Friendly – No toxic residues, making it safe for homes and businesses.

Kills Mould at Its Source – Eliminates both visible mould and airborne spores to prevent regrowth.

Removes Persistent Odours – Neutralises smells from smoke, mildew, pets, and damp conditions.

Improves Indoor Air Quality – Reduces allergens, bacteria, and airborne toxins, helping to relieve asthma and allergy symptoms.

Fast & Effective – Most treatments take just a few hours, with immediate results.

FAQs

  • Yes, when performed by trained professionals like Masters of Mould, ozone treatment is safe and effective. We ensure that all safety guidelines are followed, including temporary evacuation during treatment to allow the ozone to work efficiently.

  • Yes, ozone eliminates airborne and surface-level mould spores, preventing regrowth. However, in severe cases of structural damage, additional remediation may be required to remove deeply embedded mould.

  • Treatment duration depends on the severity of the mould or odour problem, but most residential and commercial ozone treatments take 24 hours from start to finish.

  • Ozone has a distinct, fresh scent, often described as similar to the air after a thunderstorm. The smell may linger for a few hours but dissipates as ozone reverts to oxygen, leaving a clean, purified environment.

  • No, for safety reasons, residents, pets, and plants vacate the premises during ozone treatment. Our team will talk you through the process and notify you when it’s safe to return.

  • Absolutely! Ozone oxidises odour-causing molecules, eliminating smells from smoke, pets, mildew, and more -without masking them with artificial fragrances.

  • Yes! Ozone therapy is highly effective in reducing allergens such as mould spores, dust mites, and airborne bacteria.

    By purifying the air and eliminating microscopic irritants, it can significantly improve indoor air quality, helping those who suffer from asthma, hay fever, and respiratory allergies breathe easier.

    Many of our clients notice an immediate improvement in their allergy symptoms after treatment.
