An air purifier filter system comprises an air purifier filter unit and a machine readable identifier which provides information concerning the filter unit type and performance information specific to a target pollutant to be filtered by said air purifier filter unit from a plurality of different pollutants that can be filtered by that filter unit type. This information can be used to provide an end of life prediction for the filter unit or provide advice that the filter should be changed for other reasons. This enables the user to be given advance warning, and to be given instructions when it is time to change the filter unit. The instructions to change the filter unit may be more accurate than a simple timer as they can take account of the type of filter unit and the performance information. In some examples the use history of the filter unit may also be used to predict the time when it should be changed.

The present invention relates to a method and a cooking apparatus for controlling a process for cooking food. The method comprises the steps of: detecting an initial temperature of the food; evaluating weighting factors of more than one temperature ranges according to the initial temperature, the more than one temperature ranges and preset cooking parameters of each of the more than one temperature ranges being predetermined; and controlling the cooking process based on the evaluated weighting factors and the preset cooking parameters. With this configuration, the cooking setting (temperature, time etc) can thus be determined based on the detected temperature ranges as well as the eliminated temperature ranges, so that possible detection inaccuracy can be eliminated to a large extent.

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.

A particle sensing apparatus is provided for determining particle concentration in a fluid, e.g. air. The apparatus is based on fluid-flow passageway having an upstream inlet to receive the fluid and a downstream outlet to exhaust the fluid. It also includes a recirculation passageway in fluid communication with the fluid-flow passageway. Between them, the fluid-flow passageway and the recirculation passageway define a recirculation loop. A first particle sensor is located in the recirculation loop, and other sensors may also be present at other options. A force applicator is included in the fluid-flow passageway to apply a force to the particles entrained in the fluid. The force is used to direct some or all of the particles into the recirculation loop. This provides a choice between increasing the detection limit or the detection range. A processor determines the concentration of particles in the fluid based on the concentration of particles detected at the first particle sensor.
