Filtered water systems and drinking fountains - where are the lights to change the filter?

Technology is so advanced and yet when I purchase a filter for my faucet, only a few offer the technology to show if the filter is working and if the filter is current. Also, when I take a drink from a new drinking fountain there is no light to tell me if the filter has been changed or if the filter is current. Shouldn't we have technology with our drinking water to showcase when to change the carbon filter? What water filters on the market do provide an indication of the status of the filter?
