The present invention relates to a filter system. According to an aspect of the present invention, a filter system comprises: an electrostatic adsorption filter which at least partially has positive charge so as to make negative charges existing in water adsorbed to the filter by electrostatic force; a first carbon block filter arranged at the outlet side of the electrostatic adsorption filter; a hollow fiber membrane filter arranged at the outlet side of the first carbon block filter, having pores to filter viruses existing in water; and a second carbon block filter arranged at the outlet side of the hollow fiber membrane filter. In the present invention, provided is a filter system which prevents a problem of radical reduction in the water flow rate, which commonly occurs when applying a hollow fiber membrane having pores with sizes which can remove viruses to a filter. |
