Water Filtration Pitchers - How Long 'Till Filter is Actually Dead?
I bought a Pur pitcher last June. I'm still on the same filter, though it's slowed down considerably. Is it even still filtering? It sure seems to be. The recommended time to change is three months. Those things are expensive and unless there's some compelling reason to toss it, I'm keeping it until no water passes through it.
How long to you keep yours in before changing it?
