The world’s most powerful technology for cleaning, sterilization, and decontamination.
You need long-lasting, reliable decontamination… but traditional cleaning and filtration are passive, temporary, and incomplete. This puts people, spaces, and operations at risk.
SteriClean Crystals© deliver the world’s most powerful, non-toxic cleaning and disinfection technology. The technology delivers ongoing protection for air and water and weeks of protection for surface applications. This is the technology the world has been waiting for.
Current cleaning & filtration methods leave critical gaps…
Hospitals, senior homes, offices, and agricultural sites face costly contamination risks every day:
Forever chemicals, pharmaceuticals, and toxic heavy metals persist in water and air.
UV lights are inefficient, energy expensive, carcinogenic, and do not pass through water nor glass.
Chemical cleaners (i.e. Lysol sprays and Chlorox bleach) fade quickly and do not penetrate into micro-cracks on surfaces, leaving germs to continue growing exponentially.
Wildfire smoke particles and fire gases with toxic burnt residential/commercial micro-pollutants are not properly stopped by pore-size dependent Hepa filters.
SteriClean Crystals Protect Air, Surfaces, Water, and People From Pollution
Air: Neutralizes viruses, bacteria, smoke particulates, heavy metals, and odours in real time — filling the gaps that HEPA filters leave behind.
Surfaces: Long-lasting protection penetrates micro-cracks, providing continuous sterilization for weeks, not hours.
Water: Breaks down and filters pharmaceuticals, ammonia, organics, heavy metals, and “forever chemicals” in hospital and industrial wastewater, going beyond conventional treatment.
Protective Gear: Integration into medical-grade masks and PPE keeps frontline workers and firefighters safe wherever they go. N95 and KN95 masks are only 95% effective against pollutants and viruses.
This table top cleaned with SteriClean Crystals remained germ-free for 6 weeks after initial treatment.
August 2025 testing confirmed SteriClean Crystals neutralize forest fire gases, eliminates smoke particulates, odours, and airborne heavy metals. This is a first-of-its-kind solution for protecting firefighters, communities, and the environment.
TiO2 crystals can be made from 10s nm to 100s microns. This breakthrough was made possible with an electron microscope capable of seeing one-tenth the size of an atom.
The Science Behind the SteriClean Crystals
SteriClean Crystals© are engineered to generate hydroxyl radicals, the most powerful oxidizers known to science, neutralizing viruses, bacteria, mold, fungi, mildew, chemicals, and pollutants.
Published and proven with third-party evaluation in labs and real-world installations, this platform technology delivers unmatched efficacy, versatility, and scalability across hospitals, industrial sites, agricultural applications and municipal systems.

When permanently bonded to rugged composites, the crystals are durable, self-cleaning, and capable of processing large volumes at high flow rates - providing continuous protection without downtime. Unlike conventional filters, SteriClean Crystals eliminate threats smaller than 1 micron, including smoke, heavy metals, and persistent chemical contaminants. Viruses can be 1000th of the size of bacteria!

The SteriClean Advantage
Continuous Protection: Cleans and disinfects air and water on an ongoing basis and disinfects surfaces for weeks, not hours.
Multi-Environment: Effective in air, on surfaces, and in water — even in micro-cracks and hard-to-reach areas.
Powerful & Proven: Near 100% effective against viruses, bacteria, mold, chemicals, heavy metals, and other harmful pollutants.
Safe & Non-Toxic: FDA & Health Canada approved, TiO2 has been used as a food additive for 70+ years; harmless to humans with no limit to consumption.
Scalable & Flexible: Works with existing HVAC systems, PPE, and water treatment facilities.
Who We Serve
Healthcare & Life Sciences
Hospitals, ERs, nursing homes, clinics, and labs: Reduce infections, protect patients and staff, and create safer healthcare environments.
Protective Equipment & Personal Safety
Integrate SteriClean Crystals© into medical-grade masks, PPE, and air-purifying gear to continuously neutralize pathogens and airborne toxins, protecting frontline workers, firefighters, and vulnerable populations wherever they go.
Industrial & Agriculture
Factories, food systems, and agricultural facilities: Clean wastewater, degrade chemicals and ammonia, and improve operational safety. Proven to stop spongy fungus growth on grape vines.
Environment & Public Safety
Firefighters, wildfire smoke areas, and environmental monitoring: neutralize airborne toxins, particulates, and fire gasses that are able to pass through pore-size-dependent Hepa filters.
Commercial & Residential Buildings
High-rises, office towers, and homes: Eliminate mold, mildew, fungi, and harmful pollutants from the air and surfaces.
Transportation Sector
