Red Light Shower Filter Replacement
The refill for your Red Light Showerhead Filter, so the water reaching your skin and hair stays as clean as the day you installed it. Each cartridge holds the same 10-stage filtration blend as the original — KDF-55, activated carbon, and vitamin C and E balls — working together to reduce chlorine, heavy metals and everyday residue before they hit the shower.
Please be advised that this item is coming from our supplier warehouse and estimated delivery time is 10-15 business days from order.
Designed to be swapped in under a minute, with no tools needed. Choose a single cartridge to top up as you go, or the 3-pack to keep spares on hand and avoid running low.
The Features
- KDF-55 media — reduces heavy metals and helps inhibit bacterial growth within the filter itself.
- Activated carbon — absorbs impurities, odours and VOCs from the water.
- Vitamin C & calcium sulfite — work to neutralise and remove chlorine.
- Vitamin E balls — infuse the water with skin-loving antioxidants as it passes through.
- Third-party tested — checked for reduction of chlorine, heavy metals, microplastics, VOCs and mineral residue.
- Compatible with the Red Light Showerhead Filter only — a direct, no-guesswork replacement.

A Note Before You Begin
Filtration performance is based on third-party testing and will vary depending on your local water supply; this is a shower filter, not a drinking-water system. For best performance, replace the cartridge on schedule rather than waiting for a visible change in water flow or taste.
FAQs
How do I know when it's time to replace the filter? As a guide, plan on replacing it every 75 days with regular use, though households with higher water usage or more frequent showers may need to switch it out closer to the 2-month mark.
Should I buy the single or the 3-pack? If you shower daily and want one less thing to think about, the 3-pack covers roughly a year's worth of replacements. The single cartridge suits occasional users or anyone trying the filter for the first time.Home
