What people said after living with it.

★★★★★★★★★★

Great taste improvement

Really impressed with this tap filter. The water tastes noticeably cleaner and fresher, and it was really easy to install. Definitely a worthwhile upgrade for the kitchen.
— Lucy
★★★★★★★★★★

Easy to install

I was expecting installation to be a hassle, but it took just a few minutes. The filter looks neat on the tap and the water tastes much better. Very happy with it so far.
— Oliver
★★★★★★★★★★

Better than expected

I wasn't sure how much difference a tap filter would actually make, but I can genuinely notice the difference in the taste of the water. Simple, convenient and much cheaper than constantly buying bottled water.
— Susan
★★★★★★★★★★

Perfect for everyday use

Really handy for drinking water and cooking. The design is compact and doesn't get in the way, and the filtered water tastes much nicer. It's become one of those things I wish I'd bought sooner.
— Mike
★★★★★★★★★★

Excellent value

Very pleased with this filter. It's straightforward to fit, easy to use and makes the water taste noticeably fresher. Great alternative to buying bottled water all the time.

Questions, answered

Do these filters work with my Filtraflow?

Yes — these filters are made specifically for the Filtraflow Smart Digital Water Filter. If you don't have the device yet, you can find it on our Starter Kit page.

What's the difference between the 6-month and 12-month plan?

Both ship on a subscription with no lock-in. The 12-month plan simply works out cheaper per filter (£11.25 vs £12.50) since you're committing to a full year up front.

Can I change or cancel my plan?

Yes, anytime — pause a shipment, switch between the 6-month and 12-month plan, or cancel entirely from your account with no phone calls needed.

How will I know when to replace my filter?

The device's on-screen display counts down filter life, so you'll always know when a replacement is due — your next shipment is timed to arrive just before then.

The 60-day clean water guarantee

Try your first filter shipment for a full 60 days. If you're not seeing a cleaner reading, send it back for a full refund.
