HEPA (High Efficiency Particulate Air) filters are very effective at capturing airborne contaminants above 0.3 Microns as shown in the diagram below. However, these filters are not able to capture viruses, Volatile Organic Compounds, most tobacco, general fumes and oil smoke as well as permanently suspended particles.
HEPA filters must be moist to retain airborne contaminants. Most new buildings’ interiors however are well sealed, resulting in very dry climates. Therefore, the effectiveness of HEPA filters to capture and retain airborne contaminants is relatively poor in modern buildings. Also, HEPA filters only capture airborne particulates, they do not decompose them. This means filters can become breeding areas for organic contaminants and as they reach saturation – usually within 3 to 5 months - contaminants are able to flow back into the air and cause cross-contamination.
T-Zap when coated onto HEPA filters offers significant advantages.
It captures organic contaminants below the 0.3 micron limit of HEPA filters. This includes viruses and VOCs. It also noticeably eliminates tobacco smoke and other odors from the air
It decomposes all organic contaminants. This means germs, mold and fungi cannot multiply and cause cross-contamination
The Hydroxyapetite effectively retains all organic contaminants, even under dry conditions
Germ decontaminator masks
In a time of flu pandemics, you want to have the best protection available. Xeralife medical grade, surgical masks have proven their worth from hospital operating rooms to every day use in public.
With a Bacterial Filtration Efficiency (BFE) of 99% compared to other three ply and molded face masks with BFE ratings of 85% to 92% (1), the T-Zap enhanced filter has been proven by the Biomedical Science Association (BMSA) in Japan to be effective against all forms of Influenza, including Avian flu and Swine flu.

Air conditioner decontaminator filter
T-Zap coated filters are designed to be retro-fitted into existing air conditioners’ duct systems, and are available in roll form to be cut to size. The filter is an optimal solution as it is easy to install and works effectively for up to one year. Typical applications include public buildings, offices, homes as well as modes of transportation such as airplanes, trains and buses.
Odor decontaminator
Xeralife Odor Decontaminator Sheet absorbs odors that other deodorizers and deodorants don’t. In particular, Xeralife Odor Decontaminator Sheets are effective against tobacco smoke, medical and pharmaceutical smells, toilet odors and other unpleasant smells.
Benefits
The Xeralife Odor Decontaminator Sheet absorbs and decomposes rather than masks odors. This means it permanently rids the smell.
Each sheet covers a 4 m2 area.
Lasts up to 12 months.
It works quickly.
It works in the absence of light or other external stimulation. As such, it is effective in windowless, closed environments such as closets and lockers.
The Xeralife Odor Sheet’s active ingredients are certified as food grade, and will not harm the environment, contrary to chemical based deodorizers. T-Zap absorbs and decomposes odors. Also, once decomposition is complete, only carbon dioxide and water are released into the environment.
Typical applications
Refuse bins
Refrigerator
Kitchen
Cars
Locker
Shoe racks / boxes
Closets
Pharmacy and medical areas
Laboratories
Toilets
Animal living areas, including cat litters
