The invention discloses filtering equipment comprising a first branch and a second branch, wherein each of the first branch and the second branch comprises an input end, an output end, two inductors and four nodes; four capacitor sets are connected between the first branch and the second branch in parallel, and each capacitor set is connected with the branches via nodes of the branches; the capacitors charge when an input voltage rises and discharge when the input voltage steps down, for filtering the first branch and the second branch. The technical scheme of the invention relates to the filtering equipment which utilizes magnetic energy of coupling between the capacitors for inhibiting noise, and the induced noise voltage of the capacitor is directly added into an output loop of a novel filter, so that high frequency noise can pass through the inductive branch, the coefficient of mutual induction of the capacitors is reduced, and high frequency denoising performance of the filtering equipment is enhanced, and thus frequent cross-area crosstalk and coupling of carrier signals are avoided, isolation between the areas is achieved, and acquisition of correct user information under the area is ensured.
