Removes what shouldn't be in your water: The 5-stage reverse osmosis system filters out heavy metals, chlorine, bacteria, nitrates, and microplastics — down to particles smaller than 0.0001 microns — delivering water as pure as premium bottled water, straight from the tap.
Know exactly what you're drinking: The integrated TDS sensor measures water quality in real time and displays the reading directly on the unit, giving you a clear picture of your water's purity at any moment.
Tucked away, completely out of sight: The compact, tankless unit fits neatly under your sink and connects to your existing supply and waste pipes, with no equipment visible on the worktop. The included tap needs just a single hole for installation.
Filters that last — and easy to change when they don't: The PPC filter runs for up to 12 months and the RO filter for up to 24 months. When a replacement is due, the filter life indicator lets you know in advance, and swapping it out takes just seconds.
Cut your bottled water bill significantly: Regular mineral water buyers can save several hundred pounds per year by switching to the PureFina — which runs on just 80 W and can deliver up to 1,500 litres of filtered water per day.
Product description
If you've ever squinted at your tap water and thought I'd rather not — the Klarstein PureFina is your answer. This under-sink reverse osmosis system filters your mains water through 5 stages, removing contaminants down to particles smaller than 0.0001 microns. The result? Water that matches the purity of premium bottled water, straight from your kitchen tap.
Heavy metals, chlorine, bacteria, nitrates, microplastics — the PureFina removes them all. A built-in TDS sensor monitors water quality in real time, so you can see exactly what you're drinking. Filter life is displayed directly on the unit: the PPC filter lasts up to 12 months, the RO filter up to 24 months, and the system alerts you when a change is due.
The whole unit sits neatly out of sight beneath your sink. This tankless system connects directly to your existing water supply and waste pipe — nothing clutters your worktop. The dedicated tap included in the box requires just a single hole for fitting.
Particularly well suited to families with young children, older relatives, or anyone who wants to be confident about what they're drinking every day. If you regularly buy bottled mineral water, switching to the PureFina could save you several hundred pounds a year.
Get yours today and enjoy clean, filtered water on tap — every single day.
