Jesus, I hope my wife doesn't read this! She's always on my ass to change the damned filter. Wouldn't be a big deal if it wasn't so freakin' hard to get to it. Piss poor design, and then some knucklehead that used to live here had to "remodel" the basement and put doors in the way. It's a bitch to get to.
Just emailed your wife.. You'll hear from her shortly.
