Installation guide
Follow the quick step-by-step below. If you can open a soda bottle, you can do this.
Follow along at your own pace.
Unscrew the old head by hand, counter-clockwise, and wipe the threads clean.
Wrap the arm threads with the included tape, 3 to 4 times clockwise, for a leak-proof seal.
Hand-tighten the Unchemed inline filter onto the arm. This is your deep filtration.
Screw the connector onto the bottom of the filter, snug by hand.
Attach the 5-foot hose to the connector and hand-tighten the collar.
Twist the handheld onto the hose. Its 5-stage filter makes 20 stages in total.
Turn on the water, check for drips, and enjoy. About five minutes, done.
Here's the full install, start to finish.
