Your Filter Is Working Hard. Give It a Fresh Start.
After 3–4 months, mineral stones lose effectiveness. Chlorine, heavy metals, and hard water minerals start getting through — and for women experiencing hormonal hair and skin changes, that undoes the progress you've made.
Chlorine Creeps Back
Saturated stones can't absorb chlorine, which strips your hair's natural oils — oils already reduced by hormonal changes after 45.
Hard Water Builds Up
Mineral deposits accumulate over time, leaving your hair dry, brittle, and lifeless.
Filters Lose Effectiveness
Old filters stop working efficiently, allowing contaminants to pass through and damage your hair and skin.
What Happens When You Don't Replace
Filter effectiveness drops month by month. Here's what the data shows.
Full chlorine & heavy metal removal. Maximum pressure. Your hair and skin are protected.
Slight mineral saturation. KDF-55 still active. No noticeable difference in water quality.
Chlorine starting to pass through. Hair may start feeling dryer. Order your replacement now.
Significant chlorine exposure. Pressure drops. Your shower is undoing your skincare and haircare routine.
Subscribers never hit month 4. Fresh filters arrive right when you need them.
What's Inside Every Filter
Natural mineral stones neutralize chlorine and heavy metals on contact, protecting fragile hair follicles from oxidative stress.
Mineral Stones
Coconut shell GAC adsorbs VOCs, odors, and residual compounds — giving you water that genuinely smells and feels clean.
KDF-55 Media
Copper-zinc alloy removes 90%+ of chlorine through electrochemical oxidation and inhibits bacteria growth inside the filter housing.
Activated Carbon
Coconut shell GAC adsorbs VOCs, odors, and residual compounds — giving you water that genuinely smells and feels clean.
Frequently Asked Questions
Quick answers about your filter replacement.
How often should I replace the filter?
Every 3–4 months, or roughly every 8,000 gallons.
Will this fit my showerhead?
These mineral filtration stones are designed exclusively for the Unchemed Handheld. They are not compatible with the Stationary or other brands. If you have the Stationary , check our Stationary Filter Replacement page.
How does Subscribe & Save work?
Choose your quantity and frequency. We auto-ship fresh filters every 4 months at 15% off. You'll get an email 7 days before each shipment. Skip, pause, or cancel anytime from your dashboard or by emailing us. Zero cancellation fees, ever.
Can I return an opened filter?
Unopened filters can be returned within 30 days. Because filters directly contact water, opened filters can't be returned for hygiene reasons. If your filter arrives damaged, we'll replace it free — just email us a photo.
Why are these important for women over 45?
Hormonal changes reduce natural oil production and shorten hair growth cycles. Chlorine and hard water minerals compound this by stripping the oils you have left and coating follicles. A fresh filter ensures your shower water supports your hair and skin instead of working against them.
How do I know when it's time to change?
Three signs: your hair starts feeling dryer or more brittle, you notice a chlorine smell returning, or water pressure slightly decreases. Subscribers receive a 7-day reminder email so you never have to guess.
