Query: Brita leaks baddly in 3 months. Metal faucet plastic Brita

The Brita Ultra faucet filter system was working great up until about the 3 month mark and then it just started to leak more and more and now it leaks horribly. I tried to investigate the problem and I think its simply this: The Brita faucet system is completely plastic and the faucet it attaches to is metal, so the plastic and rubber have just worn down and don't make a good seal. I have only removed the system about 3 times to clean it, as it was getting fairly dirty from regular use. I would like to make a suggestion to help you: Write the date on the filter because the light, that tells you when to put a new filter on, malfunctions regularly. I am still going to try and keep mine working and will contact the company for assistance. Hope this helps. Ohh, when I got mine it didn't fit my faucet but I told the company and they sent another attachment that did work.
