There isn’t one! Only a “softener” can soften water. A “filter” mainly removes chlorine but does absolutely nothing to soften water. It’s easy to prove this by using hardness test strips like these: HARD WATER TEST STRIPS

To get the most relief from dry skin and hair issues you need to soften the water! To get soft water, hard water minerals such as calcium and magnesium need to be removed. And the only way to achieve this in a shower is to use a salt-based ion exchange process as is used with a whole house softener and with the ShowerStick.

The ShowerStick is a portable shower water softener created for people who suffer with dry, brittle, straw-like hair and dry skin, psoriasis or eczema (also known as dermatitis). It’s a great alternative for those who can’t or don’t want to install an expensive whole house softener. Plus, it’s portable so you can take it with you if you move. And the bonus is that you won’t have all the hard water buildup (limescale) to scrub off from inside your shower and on your glass shower doors anymore.
