Fits your existing tap in under a minute and shows a live digital reading as your water gets filtered — no plumber, no guesswork, no more bottles.

Filtraflow needs a filter cartridge to work. Buy a single unit and we'll put 2 filters in the box — around 6 months of clean water, double the usual. Add extra filters below and they'll go in the same box.

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.

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.

★★★★★★★★★★

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.
