Anyone Want A Water Filter?

It's not good that I can't track stuff that I've already bought.  I got water filters delivered because I know it's been about a year since it's been changed.  After I ordered some, I went into my storage unit and saw that I have about three left over from a previous order.  I think I will now have four extra once I get around to putting a new one in.  Oops.

Now, to be fair, I might have changed it in the fall and thus checked whether I had extra in my unit, but my parents were here and Mother had a bad knee, so I was preoccupied with that.  Also, maybe not in my defense, storing these in my unit makes for an "out of sight, out of mind" situation where I wouldn't've remembered ever buying these extra filters until I bought more.  Finally, for some reason, Father turned off the humidifier last year.  In fact, it may have been over a year in which he didn't turn it on.  However, inexplicably, it looks as though he turned it back on some time during my parents' extended stay back at home.  I noticed, and then I got around to remembering the filter needed changing when I got an alarm last week that water was leaking from the humidifier while I was at work.  I went home, opened everything up and, beyond needing to clean the apparatus of limescale and calcium deposits, the water filter needs to be replaced.  This was an instance of "out of sight, out of mind," but in plain sight.

Anyway, I have to change my water filter, then store the extras back in my unit.  Great.
