G Series crude efficiency air filters in eight varieties, namely: G1, G2 filter price, G3 filter, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (activated carbon filter) , GT (high temperature coarse filter). [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - filter air purifiers efficiency]: refers to the ratio of the air purifier to remove a certain amount of clean air purifier air pollutants and rated air flow, will be for air purification efficiency of the purifier to remove contaminants, by%. Purification efficiency air purifier, the higher the quality. Air purifier of an air pollutant removal efficiency of a filter principle, does not mean that the purification efficiency for all air pollutants. Such as: respirable particle removal efficiency of 99% (50% or more qualified, more than 60% in effect for more than 99% efficient), can not be said that the purifiers microbes and toxic gas purification efficiency is also up to 99 %.
