Inside the cartridge
Three stages, one twist.
Will it fit my shower?
Lumeau fits any standard ½-inch (G½) shower arm, which covers almost every home in the US, UK, EU and Australia. An adapter and thread tape are included.
Does it reduce water pressure?
Most people notice no change. The wide plate spreads water into an even rain. If pressure drops after a few months, it is time for a fresh cartridge.
How often do I replace the cartridge?
About every three months for one person, or roughly 10,000 litres. Households with more people should replace sooner.
Is this a drinking-water filter?
No. Lumeau filters shower water to reduce chlorine and chloramine. It does not claim to remove bacteria, viruses, lead or PFAS, and it is not for drinking water.
How do subscriptions work?
Choose "Subscribe" on the refill page and a 3-pack ships every three months at 15% off. Skip, change or cancel anytime.
Does reserving cost anything?
No. A reservation saves your picks and email. You will see final prices, shipping and taxes before paying anything.
