Why is the filter replacement alert still showing after I changed the filter?

Steps

1. 1

   Press and hold the filter icon until you hear 1 beep (about 3 seconds)

   1 minMark as done
2. 2

   While the filter icon flashes red, press and hold it again until you hear 1 beep

   Alternatively, you may reset it in the PRISM+ Connect app: 

   • Device settings > "Filter reset" > "Confirm".
