Step 1: Prepare the Showerhead
Turn off the water. Hold the spray head in one hand while pressing the oval release buttons on either side of the filter housing to separate the two halves.
Step 2: Remove Old Cartridge
Twist the used filter canister to unlock and remove it. Dispose of the old cartridge.
Step 3: Check O-Rings and Seals
Ensure the O-rings are in place on both the top and bottom of the housing, and remove any airtight seals from the new filter.
Step 4: Insert New Cartridge
Remove the protective sticker from the bottom of the new filter. Place the cartridge into the spray head and twist to lock it securely.
Step 5: Reassemble the Showerhead
Align the spray head with the housing and press firmly until both halves snap back together.
Step 6: Reset the Reminder Dial
Turn the dial to the current month to help track your next filter change.
Step 7: Flush Before Use
Run warm water for at least 1 minute to flush the new filter before your first shower.
- Remove the wand from the shower base and lower it until it hangs freely by the shower hose.
- Press the oval buttons on each side of the filter housing to separate the housing.
- Once the housing is open, twist and remove the filter canister, then discard the used filter.
- Peel off the sticker from the bottom of the new filter.
- Ensure that O-rings are properly installed on both the top and bottom of the filter housing, and that all air-tight seals have been removed.
- Insert the new filter canister into the wand dock head and twist to lock it in place. Align the head with the housing and press firmly to snap the showerhead halves back together.
We’ve made it easy to stay on top of your filter changes. Each SEVENTY showerhead features a built-in reminder dial just set it to the current month when you install your new filter. The dial acts as a gentle nudge, so you’ll always know when it’s time to refresh your water and elevate your shower experience all over again.
Seventy showerhead filters are crafted to last through approximately 3,500 gallons of water that’s about 194 showers or 6 months of rejuvenating use. *Actual lifespan may vary based on household size, shower frequency, and duration.

Water quality varies depending on where you live, but most tap water contains substances that can affect your skin and hair over time. The Seventy Filtered Magnetic Handheld Showerhead is designed to help reduce the presence of chlorine, chloramines, and heavy metals, offering a gentler, more nourishing shower experience.
Bathing in unfiltered water can contribute to skin dryness, irritation, and dull, damaged hair. Our advanced filtration works to minimize these effects—leaving you feeling refreshed from the inside out.

The Seventy Filtered Magnetic Handheld Showerhead is powered by your water pressure—channeling flow through our built-in filtration system to help purify every drop.
At the core is our KDF (Kinetic Degradation Fluxion) filter, made from high-purity copper-zinc alloy. This technology uses a natural oxidation-reduction process to effectively reduce chlorine, lead, mercury, iron, hydrogen sulfide, and other heavy metals—giving you cleaner water that’s gentler on your skin and hair.
It’s normal and harmless to see a little dust or sediment when you first use one of our filtered showerheads. With KDF filters, this is often just tiny particles of the copper-zinc media inside. The golden or gold-brown residue can appear after shipping or handling but is not a contaminant or a sign of damage. New filters may release some particles if not flushed before use, but they’re completely safe and will clear once you run water through the showerhead as directed in the installation instructions.
