Abstract

A water filter system for an appliance includes a filter head assembly, a first appliance control unit positioned proximate the filter head assembly and a water filter having a memory storage unit. The water filter is selectively placed in communication with the first appliance control unit to define a filter use state. The filter use state is further defined by a first potential fluid-flow rate through the water filter and a predetermined lifetime fluid filtration amount. A data transfer mechanism defines a second data-transfer protocol between the memory storage unit and the first appliance control unit when an actual fluid filtration amount of the water filter reaches the predetermined lifetime fluid filtration amount. The second data transfer protocol defines a notification state defined by a second potential fluid flow rate, the second potential fluid flow rate being less than the first potential fluid flow rate.

First claim

What is claimed is:

1. A method comprising the steps of:
testing a water quality of water provided by a plurality of used water filters from a given geographic area;
providing a geographically tailored water filter designed to filter water received by a refrigeration appliance of a water filter user from a water source within the given geographic area to the water filter user located in the given geographic area;
installing the geographically tailored water filter into a water filter head assembly within the refrigeration appliance of the user;
filtering water using the installed geographically tailored water filter until the installed geographically tailored water filter is a used water filter;
delivering a replacement water filter to the water filter user; and

wherein the refrigeration appliance of the user is connected with a water filter provider using a wired connection or a wireless connection to connect the refrigeration appliance with a server via a global communication network of computer servers.

2. The method of claim 1 further comprising the step of:
enrolling the water filter user in an appliance water filter exchange program using a website or mobile device application whereby the water filter user elects to participate in the appliance water filter exchange program and provides water filter user identifying information; and wherein the refrigeration appliance of the user further comprises a water dispenser connected to the filter head assembly via a water conduit that delivers filtered water to the user of the refrigeration appliance.

3. The method of claim 1 further comprising the steps of:
the water filter user receiving a container for the used water filter;
delivering the used water filter to a testing facility;
testing the plurality of used water filters at the testing facility; and
shipping the replacement water filter to the water filter user.

4. The method of claim 1 , wherein the step of delivering a replacement water filter to the water filter user comprises delivering a geographically tailored water filter that is designed to filter water within the geographic area when installed and used by the water filter user based upon a water quality of water received from a municipal source or a well water source within the given geographic area of the user and wherein the water quality of water received from the municipal water source or the well water source is determined by the testing of the plurality of used water filters from the given geographic area.

5. A method for appliance water filter replenishment when substantially all or all of a useful life of a water filter has been reached or exceeded comprising the steps of:
enrolling a water filter user in an appliance water filter exchange program using a website or mobile device application whereby the water filter user elects to participate in the appliance water filter exchange program and provides water filter user identifying information;
installing a water filter into a water filter head assembly of an appliance;
filtering water using the installed water filter during a filter use state until the installed water filter has reached or exceeded its useful life and the installed water filter is a used water filter;
the water filter user receiving a container for the used water filter;
delivering the used water filter to a testing facility;
testing a water quality of water from the used water filter after it has passed through the used water filter;
shipping a replacement water filter to the water filter user;
delivering the replacement water filter to the water filter user; and
wherein the appliance is connected with a water filter provider using a wired connection or a wireless connection to connect the appliance with a server via a global communication network of computer servers.

6. The method of claim 5 , wherein the step of delivering the replacement water filter to the water filter user is automatically done without further water filter user input after the enrolling step and the replacement water filter is an appliance water filter.

7. The method of claim 5 , wherein the step of delivering the replacement water filter to the water filter user is automatically done by the filter communicating to the appliance that it has reached its notification state when substantially all or all of the useful life of the water filter has been reached or exceeded and the appliance communicating to the water filter provider that a replacement water filter is needed.

8. The method of claim 5 , wherein the step of delivering the used water filter to a testing facility comprises mailing the used water filter to the testing facility in a self-addressed container previously delivered to the user at the water filter user's address.

9. The method of claim 5 further comprising the steps of:
creating a water report; and
delivering the water report to the water filter user.

10. The method of claim 5 further comprising the step of:
testing a plurality of used water filters for a given geographic area; and
wherein the step of delivering a replacement water filter to the water filter user comprises delivering a geographically tailored water filter that is designed to filter water more effectively within the geographic area when installed and used by the water filter user.

11. The method of claim 10 , wherein the appliance is connected with a water filter provider using a wired connection or a wireless connection to connect the appliance with a server via a global communication network of computer servers.

12. The method of claim 11 , wherein the water filter provider initiates a signal communication with the appliance and the water filter and periodically obtains information about the water filter.

13. The method of claim 5 , wherein the water filter has a water filter memory storage unit and the water filter memory storage unit includes data that may be used to display one or more of the following: pieces of status or history information about the water filter to a user via a user interface: a time period of use of the water filter; a volume of water that has flowed through the filter; a percentage of use or percentage of remaining useful life of the filter; a model of the filter; and a model of the appliance to which the filter was initially engaged.

14. The method of claim 5 , wherein the water filter includes a memory storage unit in communication with the water filter provider further comprising the step of an initial start-up protocol, wherein the initial start-up protocol includes a set of encrypted instructions saved within the memory storage unit of the water filter wherein the encrypted instructions defining the initial start-up protocol are saved within the memory storage unit.

15. The method of claim 5 , wherein the step of delivering a replacement water filter comprises delivering the replacement filter to the user at the water filter user's address and the replacement water filter is a geographically tailored water filter for a given geographic area.

16. The method of claim 5 , wherein the replacement water filter is tailored to treat water based upon analyzed water characteristics within a geographic area that the water filter user resides in.

17. The method of claim 16 , wherein the replacement water filter is tailored to treat the analyzed water characteristics within a geographic area that the water filter user resides and is based upon testing conducted on a plurality of used water filters from the geographic area.

18. The method of claim 5 , wherein the
