What your filter does, why it matters, and when to replace it.
WHAT'S INSIDE
The Science in Every Refill
Two stages of filtration engineered for hot water. KDF-55 targets chlorine and heavy metals; calcium sulfite keeps working where carbon quits. Nothing lost but the buildup.
KDF-55
The first line of defense. Copper-zinc granules pull out heavy metals and chlorine before they reach your skin.
Calcium Sulfite
Built for the heat. Neutralizes up to 95.94% of chlorine at full shower temperature, so hot showers don't mean harsh water.
FILTER REPLACEMENT
Signs Your Filter May Be Ready for a Change
You've reached the recommended lifespan.
Juliet's filter is built to last 2 to 3 months. Replacing it on schedule is the simplest way to keep performance steady, so you get consistent filtration.
You notice a drop in water pressure.
Weaker flow usually means the filter media is filling with trapped particles. If pressure feels lower than it did at install, a fresh filter can restore it.
You notice hair and skin changes.
If your hair or skin feels different than it did in those first few weeks, the filter is wearing out. Those early results were the filter doing its job, and a gradual shift is your cue for a fresh one.
WHY NSF MATTERS
We didn't just pass the test. We exceeded it.
What Is NSF?
NSF is an independent organization that tests products to make sure they actually do what the label says. They have no stake in the outcome. They run the test, check the results, and either certify the product or they don't.
What is Tested?
NSF/ANSI 177 is the specific standard written for shower filters. It measures how much chlorine a filter removes from water across its full lifespan, tested at real shower temperatures.
What Does Exceeding It Mean?
There is a minimum threshold a filter must hit to be certified. Juliet didn't just hit it. It performed above it, tested at both 2,000 gallons and 3,000 gallons of water.
