    Waited too long to replace

    Posted by Mountainnana on Nov 19, 2015

    Just a word to the wise. Be sure to replace these babies per recommended 6-8 months. I waited over a year and could not get the old cartridge out of the housing. When I called Rainshower they said to try soaking it over night in vinegar and water but it still would not budge. I ended up having Rainshower send me a new housing unit. I'm back in business but learned a valuable lesson and hope to spare others learning the hard way. Service from iherb was fantastic...very quick.

    It works

    Posted by Reviewer2593555 on Oct 17, 2012

    WE use these filters for several years, and they work -my skin and hair are nicer, and once they get worse, I know it is time to change the filter cartridge.

    better than nothing

    Posted by 101010011 on Jul 14, 2012

    there is definitely chlorine reduction coming through the filter. the water quality in the city i live in in southern california is so horrid, that these filters just do not last longer than a few months of dishing out above average water quality. there is no indicator on the filter to give a status on when you should replace this, as the manual just gives an estimate of over a year. you just kinda have to go by feel, and there is no way the water coming through this filter after eight to twelve months of use feels or smells the same as the first month of use. i do notice that the colder the shower, the better the water quality, as the kdf medium used in these types of filters does have problems reducing chlorine when exposed to higher water temperatures
