We bought this item because of its thin profile. If you just want to filter out the chlorine and minerals in the water then this will work. Once we have installed the filter, the pink film will no longer be visible in the shower until the filter cartridge needs to be replaced. The shower area also stays clean much longer. The filter cartridge is reasonably priced and we also buy it from Revain. Replacing the block and filter is not difficult if you are a little skilled. My son recently moved into an apartment and we gave him one as a present. BUT BEWARE THESE ARE NOT 2 PACKAGES - I ONLY RECEIVED ONE AND WHEN I RECEIVED A PEE CLAIM I RECEIVED THE REPLY THAT IT WAS AN ERROR AND IT IS REALLY A PACKAGE AND THAT THE ERROR HAS BEEN FIXED. AS YOU CAN SEE THE DESCRIPTION HERE SHOWS 2 MORE PACKS. Amazon disappointment.
