GC Halo®

Dual action nanotechnology - 'trap and kill' surface coatings

GC has developed a pioneering formulation, GC Halo® that destroys pathogens by forming a ‘trap and kill’ layer on air filters. Fast-acting, safe and more than 99% effective against SARS-CoV-2 coronavirus, flu, bacteria and mould. Independent tests and certifications prove GC Halo’s capabilities as a filter coating to deliver cleaner and safer indoor air.

GC Halo is a breakthrough technology, providing superior, long-lasting protection with broad applications where health, safety, and wellbeing are paramount.

Dual action Nanotechnology

'Trap and kill' surface coatings

100% effective against Human Coronaviruses and Common Viruses

Independently proven to completely inactivate Human Coronavirus OC43 and Inﬂuenza A virus in liquid form – in less than one minute

At least 99% effective against SARS-CoV-2 on filters

Independently proven to trap and kill SARS-CoV-2 in dry ﬁlter format against SARS-CoV-2, the strain of coronavirus that causes COVID-19

Filters significantly
reduce airborne
SARS-CoV-2

Independent tests show a 77% reduction in airborne SARS-CoV-2 in a single pass

99.99% efficacy against mould

GC Halo® coated air filter achieved at least 99.99% fungicidal efficacy (Aspergillus brasiliensis)

Anti-bacterial

Proven to destroy over 99.99% of Staphylococcus aureus and Escherichia coli

Cost-Effective

A simple and inexpensive solution without the need to retroﬁt, simple to install and works with existing ﬁlter maintenance program

Safety Assured

Independently tested to show no observable ink particulates in airﬂow tests, no toxic chemicals used or ozone generation

ISO Certified

Independently tested for antiviral activity on textiles according to ISO 18184:2019 and ISO 13629-2:2014 for anti-fungal activity on textiles

Green Technology

HVAC systems can operate at existing energy and MERV levels with no need to upgrade. Minimal energy used in manufacturing

How to use GC Halo®

GC Halo® coated filters can be installed quickly in existing HEPA ﬁlters and ventilation systems without the need for retro-ﬁtting – making it a fast, aﬀordable and highly eﬀective way of making the air we breathe cleaner and safer.

GC Halo® for use in ventilation solutions:

As a post-ﬁlter for existing HEPA and air ﬁlters
Requires no retro-ﬁtting – a versatile solution, compatible in existing air ventilation systems
Negates the need to install higher MERV rated filters
HVAC systems can operate at existing energy levels
No additional maintenance management – becomes a part of the existing ﬁlter
Minimal reduction in performance of airflow
