Air quality monitoring, analysis and reporting system

A method, said method comprising:

• providing an air filtration system comprising an air filter and a filtration sensor, said air filter being coated with a plurality of different contaminant identifying agents at a respective plurality of spatial sections of the air filter;
• each different contaminant identifying agent configured to cause a change in one or more properties of a different contaminant as a consequence of a reaction between each different contaminant identifying agent and the different contaminant, said change being specific to each combination of contaminant identifying agent and contaminant, said filtration sensor being a device configured to measure the change in the one or more properties of each different contaminant participating in the reaction, said filtration sensor configured to determine, based on the change in the one or more properties, an identity of each different contaminant;
• flowing air containing an airborne contaminant through the air filter, said airborne contaminant in the flowing air reacting with one contaminant identifying agent coated at one spatial section of the air filter, said reacting generating a change in a property of the one contaminant identifying agent;
• said filtration sensor measuring the change in the property of the one contaminant identifying agent resulting from said reacting;
• said filtration sensor identifying an identity of the airborne contaminant due to the change being specific to the combination of the one contaminant identifying agent and the airborne contaminant, and
• reporting, by the air filtration system, the identity of the airborne contaminant.
