Abstract
An air purifier including a fan having a plurality of fan speeds; a filter, wherein the fan draws air through the filter; a user interface in communication with a control system; wherein upon activation of the control system, the control system identifies an initial air quality index (AQI) based upon a geographic location of the air purifier, a room size based upon the type of room in which the air purifier is placed, and identifies a fan speed set by a user through the user interface, and determines a target air quality index achievable in thirty minutes of fan operation is provided. Further provided is an air purifier capable of predicting and updating time to achieve a target air quality and a target air quality based on a number of environmental factors.
Claims16
An air purifier for a room comprising:
- a fan having a plurality of fan speeds;
- a filter, wherein the fan draws air through the filter;
- a user interface in communication with the fan and a control system, wherein the user interface displays a mode, the fan speed, an indoor air quality index (AQI), a target AQI, and a time to achieve (TTC) the target AQI, wherein the mode is either manual mode or automatic mode;
- a PM 2.5 sensor in communication with the control system;
- and
- one or more sensors selected from the group consisting of a volatile organic components (VOC) sensor, a CO sensor, and a CO2 sensor, said one or more sensors located on an air intake side of the fan and said one or more sensors in communication with the control system;
- wherein upon activation of the control system, the control system identifies one or more of the following:
- an outdoor AQI based upon a geographic location, the indoor AQI determined using information from the PM 2.5 sensor of the air purifier and the type of room in which the air purifier is placed, or a room size based upon the type of room in which the air purifier is placed, and
- wherein when in the manual mode, the control system further identifies a fan speed set by a user through the user interface and calculates an initial manual target AQI after thirty minutes of fan operation at the set fan speed;
- and
- wherein when in automatic mode, the control system is configured to automatically change the fan speed such that a predetermined AQI is maintained.
