SeulixRust Removal Shower Filter

I ordered this filter twice. We have been using it for about two months and there are two adults in the household. I think I could have changed the filter earlier, because for the last two weeks the water in the shower has been running slower and the filter has darkened quite quickly (but this is probably due to the extreme amount of rust in the water in our rental). I am therefore not entirely sure how long the filter will last, but a month or more for sure. My husband and I have noticed that the filter helps us and our skin is not irritated, and we both have very sensitive skin.
