Product review (1 stars): Two defective filters in a row?
I bought one in February and installed it in April. By early June, the water dispenser was "chattering" (knocking/jittering/jackhammering) for a second whenever the button was pressed. By mid-June it was constant, and no water was dispensed. I thought it might be a problem with the filter, so I bought another and installed it at the end of June. By the end of July, the chattering was back, worse than ever. I didn't think it could be the filter after less than a month of using it. A couple hundred dollars of repairs later...it was the filter. I bought a Whirlpool branded filter (actually a 2-pack for the same price I paid for a single PUR filter). No chatter. Fridge is fixed. And I'm just a week outside the window to return the one I have, or it would be back in the mail. Not buying another one of these!
