Water Filter Leaking

Water running all over the floor from under the fridge the repairman said the filter was leaking and we put a new one in. Fixed the problem until about 2 weeks later same issue. I replaced the filter, fixed the problem. One month later same problem, changed the filter again. I understand that they need to replaced every 6 months or so, but every month seems a problem. Luckily I have been home each time and heard the water running and could shut it off. If I was gone or if it happened during the night I would have a BIG flood. Is this normal???
