(A) Photo-catalysis (NanoMax®)

Photo-catalyst facilitates chemical reactions by absorbing light. When a photocatalyst titanium dioxide (TiO₂) captures ultraviolet light (UV) either from sun or fluorescent light, it forms two types activated oxygen (Hydroxyl Radical and Superoxide) from water or oxygen in the air. This process is similar to photosynthesis, in which chlorophyll captures sunlight to turn water and carbon dioxide into oxygen and glucose. The formed activated oxygen is strong enough to oxidize and decompose organic materials or smelling gas, and kill bacteria.

 

  
(B) HEPA (High Efficiency Particle Arresting) Filter

This is most widely known method for purifying air. Depending on the filter size, it can clean up to 99.99% of particulate in the air with proper ventilation.

However, this alone has limited effectiveness on treating mould, mildew, bacteria, and other fungi.

 
(C) Electrostatic Filtration

Another filtration system with a negatively charged surface is used to attract particulate. In comparison to most HEPA systems it is more effective in trapping smaller micron particulate and effective in clearing smoke from the air. Low levels of ozone may be produced which can neutralize most mould, mildew, bacteria, and other fungi that comes in contact with the filter.

 
(D)Ionizer

Uses a negatively charged surface to produce and expels an abundance of negative ions and cause suspended particles to cling to walls, floors, and other surfaces. Most ionizes are effective in settling dust and particulate out of our breathing space.
 
(E) UV Germicidal Lamps

Commonly used for disinfecting purposes. This technology is effective in sterilizing air and surfaces that come in contact with the UV light. UV has been proven in both air and water applications to inactivate bacteria and viruses preventing them from reproducing.
 
(F) Ozone

Ozone is a very powerful oxidizer that will neutralize odours, mould, mildew, bacteria, and other fungi. This technology is commonly used in flood and fire restoration. Ozone is found to be effective because it works on the problem at the source and air does not have to be pulled through the unit for treatment.
