you can't take a shower in your kitchen sink.

Seriously they are course filters at best, they don't do the job

They state the following "Running hot water through the filter will decrease the effectiveness of the filter. "

The water needs to be filtered at source as it enters the home, ie:cold

The cost of the Pur replacements is $25 4 times a year, the fridge filters are $40 twice a year, so $180 a year, but it still isn't filtering the whole house.
