Patent number: 11890568Abstract: 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.Type: GrantFiled: December 15, 2015Date of Patent: February 6, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hendrik Richard Jousma, Declan Patrick Kelly, Einte Holwerda, Jean-Paul Jacobs, Cornelis Reinder Ronda, Jean Bart Bleeker, Koray Karakaya

Patent number: 11725614Abstract: A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.Type: GrantFiled: March 17, 2020Date of Patent: August 15, 2023Assignee: MANN+HUMMEL GmbHInventors: Volker Kuemmerling, Thomas Jessberger, Andreas Weber, Michael Metzger, Bernhard Gau, Naihe Shen, Calogero Colletto, Achim Janner
