WHAT IS HEPA FILTRATION MEDIA - (High Efficiency Particulate Air )
The HEPA air purifier was originally developed to filter out radioactive airborne particles from the air space surrounding nuclear generators during the Second World War. It is a type of air filter that is used in air cleaning equipment including vacuum cleaners. Most HEPA air cleaners will filter particles in the airborne environment down to 0.3 microns in size, at an efficiency rating of 99.97%. They will filter and remove some of the smallest microns of allergens such as dust, smoke, pollen, animal dander, etc. The 0.3 micron size was selected for HEPA testing because it is the most difficult to capture. Testing by filter manufacturers and filter testing companies has shown that HEPA filters can actually be more efficient than 99.97% for capturing particles smaller or larger than 0.3 microns.

Photo catalyst
The main material of photo catalyst is TiO2 which can activate the chemic actions under the normal temperature with the help of ultraviolet light. The energy of the UV light can blaze the molecules around the photo catalyst to be uncontrolled radicel which can break down most of the organic or inorganic materials and form CO2 and H2O.

Static plasma
The technology of dust removing with electric static plasma is applied the fundamentals of gaseous discharge and electrophorus dust. When the air with particulates goes through the static plasma, the gas is discharged by the high voltage to collect the dust on the surface of the plasma panel.
