METHOD FOR MONITORING AND PURIFYING AIR

摘要

An air purifier is presented with a sensor controlling a motorized fan, wherein the sensor continuously and automatically adjusts the sensitivity setting of the sensor as the quality of air being purified changes. The average air quality readings of the air passing through an air purifier are monitored over a designated time period and, as the quality fluctuates, the sensitivity of the sensor is automatically adjusted. If the air quality is poor (i.e. a high particulate count), the sensitivity of the sensor will be adjusted to a less sensitive setting (i.e. allowing higher fan speeds so that more air can be moved through the filter) and, if the air quality is good (i.e. a low particulate count), the sensitivity of the sensor will be adjusted to a more sensitive setting (i.e. setting a lower maximum fan speed because not as much air needs to move through the filter).

主权项

1. A method for purifying air, comprising:
passing air over a particle counter in communication with a control system; determining through the control system an initial level of air quality based on a particle count detected by the particle counter; designating a first sensitivity setting of a sensor in communication with the control system and further in communication with a fan, wherein the first sensitivity setting allows the fan to generate a first set of airflows; determining through the control system a second level of air quality based on a second particle count detected by the particle counter; if the second level of air quality deviates from the initial level of air quality by more than a specified amount, adjusting the first sensitivity setting of the sensor to a second sensitivity setting, thereby allowing the fan to generate a second set of airflows.
