I bought this jug about 6 weeks ago & once it arrived, I could replace my hotcup, boiling water dispenser & water filled fan/air purifier, without worrying about them both scaling up beyond help again, the new ones are both working perfectly, now that I use Brita filtered water, where their predecessors failed & scaled very quickly. My cups of tea & squash are now much more tasty. I wouldn't be without my Brita jug now.  Great for hard water areas.
