Query: Don't buy until you know the filter works with your faucet!

I bought the filter, but was not a good fit for my faucet because it sprayed water everywhere. I tried to return, but because it is a replacment cartridge you have to pay for the return shipping even though it was not used (they pay for the return shipping for the filter, just not the replacement cartridge). I tried to explain to them if I am returning the filter, then I do not need a replacement filter. My advice, don't buy the replacement until you know the filter works with your faucet.
