An Environmental Control System includes a sensor, an air purification subsystem, and a controller in communication with the sensor and air purification subsystem. The sensor detects a contaminant in the air and generates a contaminant signal. The controller compares the contaminant signal to a predicted sensory response threshold. When the contaminant signal reaches the predicted sensory response threshold, the controller commands the air purification subsystem to alter a condition in the air.

1. An environmental control system (ECS) having contaminants in air therein, comprising: a sensor;an air purification subsystem; anda controller in communication with the sensor and air purification subsystem;wherein the sensor: detects a contaminant in the air; andgenerates a contaminant signal;wherein the controller: compares the contaminant signal to a predicted sensory response threshold;wherein the predicted sensory response threshold is one of odor, irritancy, mass, and a combination thereof;wherein the predicted sensory response threshold is based on a plurality of contaminant sample population percentiles;wherein the predicted sensory response threshold is below a dose addition sensory irritancy of 1.0; andwhen the contaminant signal reaches the predicted sensory response threshold, commands the air purification subsystem to alter a condition in the air containing the contaminant. 2. The ECS of claim 1, wherein the air containing contaminants includes outside air entering the ECS through engine and APU bleeds, or other air sources including ground supplies and electric compressors, and recirculated air circulating through the ECS. 3. The ECS of claim 1, wherein the contaminant signal is based on one of odor, irritancy, mass, and a combination thereof. 4. The ECS of claim 1, wherein the contaminant signal is based on a sample of anticipated contaminants in the air. 5. The ECS of claim 1, wherein the predicted sensory response threshold is based on a percentile population of anticipated contaminants in the air. 6. The ECS of claim 1, wherein the predicted sensory response threshold is based on one of an odor threshold, an irritancy threshold, a mass threshold, and a combination thereof. 7. The ECS of claim 1, further comprising a valve, a mix manifold, and a fan in communication with the controller. 8. The ECS of claim 1, wherein sensor senses one of outside air entering the ECS, recirculated air circulating through the ECS, and a combination thereof. 9. A controller for an environmental control system (ECS) having a sensor and an air purification subsystem, wherein the controller: communicates with the sensor and air purification subsystem;receives a contaminant signal from the sensor;compares the contaminant signal to one of a contaminant concentration look up table and a contaminant mass look up table;wherein the comparison of the contaminant signal includes identifying a probability of contaminant detection against a predicted threshold of one of odor and irritancy;wherein the probability is a dose addition sensory irritancy of a plurality of contaminants; andbased on the comparison, commands the air purification subsystem to alter a condition of contaminated air in the ECS. 10. The controller of claim 9, wherein the contaminant concentration look up table includes contaminant concentrations at population percentiles of a sample of anticipated contaminants in the contaminated air. 11. The controller of claim 9, wherein the contaminant mass look up table includes contaminant masses at population percentiles of a sample of anticipated contaminants in the contaminated air. 12. The controller of claim 9, wherein the comparison of the contaminant signal includes comparing the contaminant signal to an average sensory response threshold. 13. The controller of claim 9, wherein the comparison of the contaminant signal includes identifying a probability of contaminant detection against one of a contaminant concentration equivalent response from the sensor and a mass contamination response from the sensor.
