The KDF Shower Water Filter can be installed in-line with the ShowerStick, Portable RV Water Softener or The Mini WaterSticks or it can be installed by itself in a shower. It installs in minutes with no tools on any shower pipe with standard 1/2? pipe threads. To install by itself in a shower, simply unscrew your shower head from the shower pipe, attach the KDF filter to the shower pipe then add your shower head.
The KDF filter should be replaced yearly if 2 people are using the shower (or sooner if you smell the presence of chlorine).
