Abstract: A non-woven fabric composite and an article including the same are provided. The non-woven fabric includes an electrostatically treated meltblown non-woven fabric layer and a spunbond non-woven fabric layer on one or both sides thereof, and has a fine dust removal performance retention ratio, represented by Equation 1, of 80% or more: Fine dust removal performance retention ratio (%)=(fine dust removal efficiency after accelerated aging treatment)/(fine dust removal efficiency before accelerated aging treatment)×100  [Equation 1] wherein, in this equation, the fine dust is an aerosol containing sodium chloride dispersed in air, and the accelerated aging treatment refers to a case where the non-woven fabric composite is stored at a temperature of 70° C. for 3 days.
