The crux of the matter of this essay is to explore the radical of a prefilter (R(W) for short) in EQ-algebras. To begin with, the notion of the radical of a prefilter is defined and R(W) with the help of an unary formula is characterized. After that, the relations between prefilters and radicals of prefilters are investigated. Finally, the definition of semi-maximal prefilters is given. That a (maximal, implicative, obstinate) prefilter is also a semi-maximal prefilter is obtained.
