Query: I took it apart

I took apart the Culligan and I can't imagine how it filters water. It's a solid block of charcoal (so 1 star for that) poorly glued to the top (I was able to pull it off with moderate amount of tugging) but with small gaps at the bottom which sorta explains the low water pressure and explains another person's review why his PPM test was the same with and without the filter (265 versus 265). And the only reason I took it apart was because I used this Culligan to filter water for my tea kettle and I noticed that tea kettle had become chalky white which I guess is the residual chlorine from the water which got me thinking does this thing even work? So, I took it apart and the rest is history.I highly suggest you take yours apart and see for yourself.
