Heh, it looks like purr without the little symbol over the “u”.

Thank you, PUR, for the little reusable sticker system that tells me when the filter is old and needs to be changed. Only, we go through a lot of filtered water up in here and your sticker system is off by like a month and a half. Sure, we could split the difference and move the sticker according to our own personal watering habits. But that requires math and I gave that up in college.
