Eight stages between hard water and you
Every drop runs through an 8-stage cartridge. Its calcium sulfite and KDF-55 stages are designed to reduce chlorine, and the KDF-55 media was over 99% antibacterial in lab testing. KDF-55 is designed to help with limescale build-up too. Twist in a fresh cartridge every 3 months to keep it working at its best.
Highly recommend to anyone in the UKUK water is notoriously hard in most areas and this is the perfect solution. Effective, affordable and easy. Anyone in England especially should have one of these in their shower.

Ordered a second one immediatelyLiked the first one so much I ordered a second the same week for our other bathroom. Same great results in both. TENDRA have a customer for life here.

Honestly didn't expect much but was blown awayBought this on a whim after seeing it on Instagram. Zero expectations. After three weeks I genuinely can't imagine going back to a regular shower head.

Questions
Does it help with hard water?
TENDRA Pure™ is made for hard-water areas like London. Its calcium sulfite and KDF-55 stages are designed to reduce chlorine, and the KDF-55 media was over 99% antibacterial in lab testing. KDF-55 is also designed to help reduce limescale build-up. How much difference you notice depends on how hard your local water is. Check your postcode.
How fast is delivery?
Orders are dispatched within 1–3 working days by Royal Mail 48, so most arrive within 3–6 working days. Delivery is free on UK orders over £35. We also ship worldwide, free over £75, usually within 5–10 working days of dispatch. Delivery and returns.
Will it fit my shower?
It fits standard UK ½-inch (G1/2) shower hoses and arms, which most handheld and wall-arm showers use. Not sure? Check in 30 seconds.
Can I fit it in a rented flat?
Yes. It screws on by hand with no tools and no drilling. Keep your old shower head and put it back when you move.
How often do I change the cartridge?
Every 3 months for one person showering daily, or sooner if more people share the shower. Your Shower Score tells you exactly.
Can I combine offers?
Bundle savings are already in the price: shower head + spare cartridge saves £11, a year of filters saves £27. On top of that, you can use one discount per order: a code or our automatic flat deal for 2+ shower heads, not both.
What if I don't like it?
Try it for 30 days. If it isn't for you, return it within 30 days of delivery, even if you've used it. How returns work.
