The Science of
Lung-Gard®
A patented Made in Italy air-treatment technology designed to integrate into existing HVAC systems as an additional protective layer.

PURITY TECH technology is a new filtering system consisting of an antiviral, antibacterial, and anti-pollution fabric all in One.
Air management in enclosed spaces is essential to prevent the spread of viruses and bacteria and to remove polluting gases from outside.
FABRIC TREATMENT
- Coating AZM: The air contact surface is treated with an innovate technology; the AZM coating allows the direct transfer of molecules towards the fabric, without environmental impact.
- Positive Ion Plasma: The process generates a positive Ion Plasma that, when accelerated, forces the antiviral atoms to transfer to the surface of the tissue.
The treatment gives the tissue virucidal characteristics such as to obtain an international certification virus abatement by up to 99,87% (ISO 18184:2019).
Integration Principle
PURITY TECH® is installed as an additional layer over your existing HVAC filter. As air flows through the system, it passes through the treatment layer before entering the building's circulation.
Air Intake
Air enters the HVAC system normally.
Primary Filtration
Passes through existing dust filters.
Active Treatment
Passes through PURITY TECH® layer.
Circulation
Treated air enters occupied spaces.
Performance without compromise
Engineered to enhance protection without altering system dynamics.
Optimal Airflow Maintained
The proprietary structure of the Lung-Gard® layer ensures that air passes through with minimal resistance. This means no significant pressure drop, ensuring your HVAC system doesn't have to work harder, maintaining energy efficiency and cooling performance.
No Modifications
Works seamlessly with your existing HVAC configuration. No structural changes or electrical wiring required.
Universal Compatibility
Integrates with any standard HVAC filter type across commercial and residential systems.
Durable Performance
Designed to match or exceed the lifespan of standard HVAC filters, requiring replacement only during your regular maintenance schedule.
