Pre Filter

Pre Filters

A Pre Filter is a filtering device which removes unwanted particles like dust, insects, pollutants and other microbes before they reach the main filter. The main purpose of Pre Filter is to stop the dirt and other dust particles from entering the main filter. Thereby, Pre Filters can be considered to be a cost saving measure since they enhance productive life of the main filters. Air filter equipment fitted with Pre Filter can be used in buildings, public places, transport facilities and so on

Air filters are installed in facilities and places to improve the air quality of the indoor surroundings. Pre Filter is washable and can be cleaned with wet/ dry cloth and it should be cleaned every 4-6 months. Of course, the HEPA filters which are equipped in the air filters can perform all the activities of a Pre Filter. But, in that case as the time moves ahead, the dust particles get built up and decrease the efficiency of the air filter.
