Some of you might live in a place (like an apartment) where you do not have access to install a whole-home water softener. So what about a water filter? Will that work just as well?
Yes, and no.
Obviously, you’re only removing the minerals from the water at the source, which is the shower. This could be adequate if you have just one shower or just one place where you need to soften the water. Water shower filters can be effective, and they’re better than nothing, although they’re not as good as a water softener. On the plus side, they are relatively easy to install as well, not needing a plumber.
