Systems and methods for monitoring air quality and events likely to affect air quality, and taking remedial action

A computer-implemented method of monitoring and maintaining air quality, comprising:

• detecting, by at least one sensor, operation of a mechanism within or at a boundary of an indoor environment, wherein the mechanism is external to an air purifier associated with the indoor environment;
• determining, by a controller, integral to the air purifier, based on a signal received by the controller from the at least one sensor, a likelihood that operation of the mechanism will cause a measure of air quality within the indoor environment to fail one or more air quality criteria;
• selectively provide, based on the likelihood, an indication that operation of the mechanism will cause the measure of air quality within the indoor environment to fail the one or more air quality criteria;
• and
• cause the air purifier to take remedial action to prevent the measure of air quality within the indoor environment from failing the one or more air quality criteria.

An air quality-monitoring system, comprising:

• at least one sensor configured to detect an air quality within or at a boundary of an indoor environment;
• a persistent memory for storing data about the indoor environment observed by the at least one sensor;
• a controller, remote from communicatively coupled with the at least one sensor and configured to:
• assemble the data into an air quality profile associated with that environment;
• determine, based on a signal from the at least one sensor and on the air quality profile, a likelihood a measure of air quality within the indoor environment fails one or more air quality criteria.
