We have a Six stage Air Filtration system , 3 Mechanical Filters ( Pre Filter,Carbon Media Filter and H.E.P.A. filter ) and 3 Electrical Filters ( E.S.P. filter,U.V. Filter and Ionizer Filter ) a) Our First air filter is a 5 Micron Pre-Filter which removes the dust particles from the air. b) Our Second Air Filter is E.S.P. ( ElectroStatic Precipitator ) is a filter which is charged with a series of positive and negative plates which creates a potential difference and as a result when microbes pass through it,depending upon their charge are attracted to plates of opposite polarity and are incinerated/destroyed. c)The third filter is the U.V. Filter , this filter emits U.V. rays of 253.7 nn which is the most effective wave length against Air Borne microbes. Any microbe ( Virus,bacteria,fungus and mold ) which may have survived the E.S.P. will be put in the COMA once they are exposed to the U.V. rays. Our U.V. tube is designed to ensure that any ozone gas which may be created remains inside the glass chamber and is not exposed to the room. d) Activated-Carbon Media Filter, this filter removes the VOC ( Volatile Organic Compound ), bad odor. e) True H.E.P.A. H-14 Filter, this filter of pore size 0.3 micron ensures that any microbe ( Most of the microbes are of size 0.5 Micron and above ) is trapped/arrested and not allowed to re enter the room space. Once the microbe is trapped it cannot exit the H.E.P.A. filter even when the Air Purifier is switched off. We use True H.E.P.A. H-14 filter to provide you 99.999 % purity of the air at the output. f) Ionizer filter, Ionizer is an independent filter which generates negative ionz which spread in the room and arrests the free flowing air particles and nutralize them. The combined action of the pre filter, E.S.P.,U.V.,Carbon,H.E.P.A. H-14, Ionizer ensures the Air in the room is maintained at a minimum of 85 % of purity level during the period of operation of our MATE Air Purifier.
