Mould Growth and Your Health

Mould is more than just an eyesore. It damages building materials, worsens indoor air quality, and creates health concerns for families, tenants, employees, and customers. For homeowners and small business owners, the challenge is not just cleaning up visible mould; it is stopping the constant cycle of mould returning. The key is to treat both mould spores in the air and mould colonies on surfaces, while preventing future growth.

Mould spreads through microscopic spores that travel easily in the air. Once they land on damp surfaces such as drywall, wood, or carpet, they begin to grow. Because spores are invisible to the naked eye, mould problems often return after surface cleaning.

Common Areas Where Mould Grows

• Basements, attics, and bathrooms in homes
• HVAC systems and ductwork that circulate spores
• Kitchens, storage rooms, or bathrooms in small businesses

Filtration alone is not enough. While HEPA filters can capture spores, they do not destroy them. Spores can bypass filters or settle on surfaces where they can grow again.

Chemical cleaning is temporary. Disinfectants may kill visible mould but cannot reach spores in the air or hidden in porous surfaces. Once new spores enter the building, growth begins again within 24–48 hours.

Asthma, and Respiratory Health

Mould does not just damage property. It also poses risks to people with asthma and other respiratory conditions. According to the American Lung Association, mould exposure can trigger asthma symptoms and worsen lung function, especially in children, seniors, and those with compromised immune systems.

Pyure’s hydroxyl technology continuously reduces airborne and surface mould spores, helping to lower the risk of mould-related asthma flare-ups while keeping your environment clean.

Pyure systems bring the power of the outdoors inside. Pyure generates safe levels of hydroxyl radicals,  the same molecules created outdoors by sunlight. These hydroxyls, along with their organic oxidants, spread throughout a space, continuously breaking down mould spores at the molecular level. Unlike ozone generators, hydroxyls are safe for continuous use around people, pets, and plants. Pyure’s efficacy has been validated in independent laboratories:

• The Pyure MDU/Rx™ reduced Aspergillus niger mould spores by 99.998% in under two hours during chamber testing.
• Surface studies showed over 93% reduction within six hours and more than 99% reduction within 12 hours on glass surfaces.
• Continuous testing demonstrated that Pyure kills microorganisms both in the air and on surfaces, preventing recontamination.

Real-world case study on mould prevention

One powerful example of Pyure technology in action comes from the maritime industry. A 50-meter yacht was forced out of service when multiple species of mould were detected onboard. The contamination was so severe that crew members were relocated to hotels for over a month, while the captain slept on the sun deck to avoid entering the interior.

To restore safe conditions, Pyure’s maritime distribution partner Vikand installed several Pyure IDI™ air and surface purification devices directly into the vessel’s air handlers. Prior to activation, mould test kits placed in different parts of the yacht, including the kitchen, wheelhouse, and both port and starboard air handling units,  showed heavy growth after just three days.

When the IDI devices were switched on and allowed to run continuously, new test kits placed in the same locations told a different story. After seven days, mould growth was almost entirely absent. The comparison confirmed that Pyure’s Dynamic Protection technology had neutralized mould spores in both the air and on surfaces, creating a healthier, safer environment for crew and passengers.

The same approach that kept this yacht mould-free can be applied in homes, offices, and small businesses — anywhere mould spores threaten air quality, health, or building integrity.

Where Pyure Works Best

• Homes and condos — basements, bathrooms, attics, and living spaces
• Small businesses — restaurants, offices, retail stores, and clinics
• Multi-unit properties — apartments, condos, or boutique hotels where shared air systems can spread mould

Portable and In-Duct Solutions

• Portable units such as the Odorox® Slimline and Boss are ideal for basements, storage areas, or rooms with recurring moisture problems.
• In-duct systems integrate directly into HVAC equipment to provide whole-building mould prevention.

Why Choose Pyure Over Other Mould Solutions

• Proven efficacy: Laboratory studies following FDA GLP guidelines confirm Pyure’s ability to neutralize airborne and surface mould spores at levels far greater than filters or chemicals.
• Safe operation: Unlike ozone generators, Pyure hydroxyls are safe for use in occupied spaces.
• Comprehensive coverage: Pyure sanitizes the air and surfaces simultaneously, preventing mould from returning.
