The AP12000S-KF offers features such as a 12hr programmable timer, dehumidifier function (90 pints per day), 3 fan speeds, digital thermostat control with a 61F to 89F setting range, remote control and caster wheels. The unit includes a washable pre-filter and one replaceable carbon filter to help control odors and pollutants.

Furthermore, it also uses R-410A refrigerant for cooling, which does not contribute to ozone depletion.
