Operational parameters of an aircraft vapor cycle refrigeration system are measured via a plurality of sensors while the vapor cycle refrigeration system is operating. The measured operational parameters are transmitted to a computer system. The computer system generates, using a first reduced order model corresponding to an unclogged state of a filter of the vapor cycle refrigeration system, a first predicted discharge pressure of a compressor based on the measured operational parameters. The computer system generates, using a second reduced order model that corresponds to a clogged state of the filter, a second predicted discharge pressure of the compressor based on the measured operational parameters. The computer system determines a remaining useful life of the filter based on the first predicted discharge pressure, the second predicted discharge pressure, and a measured discharge pressure of the compressor. The computer system outputs an indication of the remaining useful life of the filter.
