Query: Leaks too

As with others here and elsewhere on the 'net (see youtube for good examples), mine developed a leak around the bottom of the mounting nut a few months after installing it and only has only gotten worse the more I've tried to do something about it (tightening the nut, cleaning the washer/screen, using teflon tape on the faucet threads, etc.). I've continued to use it even with the leak but it now sprays so badly I'm afraid I need to find another solution. I've only gone through two filters.I tried a Britta filter before but their plastic threads stripped not long after installing that and I was hoping the Pur unit would be the answer... Guess I'll keep looking.
