    • In various embodiments, an air purification system (100, 300, 400) may include a first air filter (316, 416) that targets at least a first type of pollutant.In various embodiments, air that passes through the first air filter may be unobstructed by other air filters. In various embodiments, a second air filter (316, 416) may target at least a second type of pollutant that is different than the first type of pollutant. In various embodiments, air that passes through the second air filter may also be unobstructed by other air filters.In various embodiments, a controller (102, 302) may be configured to selectively move the first and/or second air filters to expose one or both of the first and second air filters to one or more air streams, e.g., based on user input and/or on one or more signals from one or more pollutant sensors (106, 306).

    • A sensor system is provided for measuring particle concentration and mass concentration in an aerosol. An optical sensor (33) is used for measuring a particle concentration and a mechanical sensor (32) is used for measuring a mass of collected particles. A particle concentration in the aerosol is monitored using the optical sensor (33), until detection of a particle generating event. Upon detection of a particle generating event, a mass measurement using the mechanical sensor (32) is performed and the mass measurement is used to calibrate the optical sensor (33). This approach enables the lifetime of the mechanical sensor to be extended, because it is only used when events are detected. The optical sensor, which typically is less accurate for mass sensing, is calibrated by the mechanical sensor.
    • 提供了一种用于测量气溶胶中的颗粒浓度和质量浓度的传感器系统。 光学传感器(33)用于测量颗粒浓度,机械传感器(32)用于测量收集颗粒的质量。 使用光学传感器(33)监测气溶胶中的颗粒浓度,直到检测到颗粒产生事件。 在检测到颗粒发生事件时,使用机械传​​感器(32)进行质量测量,并且使用质量测量来校准光学传感器(33)。 这种方法使机械传感器的使用寿命得以延长,因为仅在检测到事件时才使用。 通常对于质量感测不太准确的光学传感器通过机械传感器进行校准。

    • Methods and apparatus for determining levels of gaseous elements and optionally utilizing the determined levels to calibrate one or more sensors of an air purifier. For example, in some implementations a first image is captured of a colorimetric sensor device at the start of a sensing period and a second image is captured of the colorimetric sensor device at the end of the sensing period. The colorimetric sensor device includes at least one colorimetric sensor configured to change colors in response to reaction with a gaseous pollutant. Values may be determined based on the colors of the colorimetric sensor in the first and second images and the values may be utilized to determine a pollution value indicative of the amount of the gaseous pollutant to which the colorimetric sensor was exposed during the sensing period.
