Pur Water FM3400

[akoin]

I have a pur water fm3400 & want to get a better one with the same features in stainless steel. I also attached a sprayer to mine. Can you tell me which models have that feature so I can get the filter with these features & if it should last longer. I take it off to wash clothes when I have to use my washer. It starts to crack at the hookup part so I thought the stainless steel would be better when it comes to removing it for my washer. Thanks.
