Mould in housing is often treated as an isolated incident. A complaint is raised, visible mould is cleaned, and the problem appears resolved. Yet in many homes, it returns. The reason is simple: mould is not the issue itself, but a visible sign that the indoor environment has fallen out of balance.
ArcAirTech exists to address that imbalance.
Rather than masking symptoms, ArcAirTech provides a two-layer environmental protection service that allows properties to actively manage mould and airborne contaminants. Together, our systems give homes a form of built-in environmental defence, often described as an immune system for the property itself.
Addressing the Environment, Not Just the Surface
Mould spores are microscopic, persistent, and often already embedded throughout a property. Cleaning visible growth alone does not remove the airborne and surface spores that allow mould to re-establish, nor those buried deep within porous materials such as carpets, mattresses, soft furnishings, and fabrics.
ArcAirTech’s Portable and Fixed systems are designed to both eliminate existing mould spores and help prevent them from reforming. They do this not only in the air, but across surfaces and within porous materials where traditional methods cannot reach.
At the core of this capability is our patented ARC technology, which generates hydroxyl radicals — nature’s most powerful cleaning molecule. Hydroxyls occur naturally outdoors, where they play a key role in breaking down pollutants and contaminants in the atmosphere. ArcAirTech recreates this process indoors, allowing contaminants to be neutralised at a molecular level.
By combining hydroxyl generation with multiple complementary technologies, our systems actively neutralise mould spores and other airborne contaminants throughout the entire indoor environment, addressing the root cause of recurrence rather than offering short-term relief.
Independent testing has shown up to 99.9% reductions in surface and airborne mould spores, including some of the most harmful types.
Portable ARC: Rapid Response Protection
The Portable ARC is designed for situations where mould has already been reported. It is quick to deploy, simple to install, and can be placed into a property without disrupting the tenant.
Once switched on, the Portable ARC senses increases in airborne contaminants and automatically adjusts its output. It responds dynamically to environmental challenges, working immediately to neutralise mould spores and other harmful particles throughout the home.
This rapid response allows housing providers to:
Fixed ARC: Continuous Environmental Defence
The Fixed ARC provides a long-term layer of protection. Installed within a property, it operates continuously in the background, helping to maintain a healthier indoor environment day after day.
Unlike reactive interventions, the Fixed ARC does not wait for visible mould or tenant complaints. It works quietly and continuously to eliminate mould spores and other airborne contaminants as they appear, reducing the risk of mould proliferating and re-colonising on surfaces—ultimately breaking the cycle of recurring issues.
A Complete Protection Model for Housing
Together, The Portable ARC and Fixed ARC form a complete, scalable service:
This allows housing providers to move beyond repeated clean-ups and towards properties that actively protect themselves against mould.
Proven in Real Homes
ArcAirTech’s systems have been deployed and tested across real residential properties. Results seen in homes consistently align with independent lab testing, with housing teams reporting reduced mould recurrence, improved indoor air quality and positive tenant feedback.
Today, ArcAirTech supports over 40 housing associations across the UK, working across both social and private housing portfolios. Adoption continues to grow as housing organisations look for effective, evidence-based ways to manage mould and indoor air quality.
Supporting Housing Partners
ArcAirTech works alongside landlords, housing teams and maintenance providers to support compliance with evolving expectations around damp, mould, and tenant wellbeing. The technology integrates into existing processes and provides measurable results that can be demonstrated to tenants, regulators and stakeholders.
Most importantly, ArcAirTech helps housing providers shift from reactive, symptom-led strategies to a model that restores and maintains healthy homes.
This is not simply about removing mould. It is about restoring homes back to health — and keeping them that way.
