A method for estimating efficiency of a particulate filter of a vehicle is provided. The method includes: calculating a first estimated value representing an amount of particulate matters (PM) accumulated in the particulate filter; upon determining to perform regeneration of the particulate filter based on the first estimated value, injecting fuel into the particulate filter and combusting the PM; calculating a second estimated value representing an amount of particulate matters accumulated in the particulate filter after the regeneration; and determining whether a PM accumulation condition of the particulate filter requires user attention based on the second estimated value.
