Top features
Filtered water straight from the tap: The tank-free system installs neatly under your sink, completely out of sight, and delivers filtered water at a flow rate of 2 litres per minute — no bottles to buy, no filter jugs to refill.
Removes what you can't see: Five stages of reverse osmosis filtration tackle heavy metals, chlorine, bacteria, nitrates, and microplastics, filtering down to particles smaller than 0.0001 microns. The integrated TDS meter gives you a real-time water quality reading whenever you want it.
Saves you money, year after year: Households that buy bottled water regularly can save several hundred pounds a year by switching to mains-filtered water. At 800 GPD (3,000 litres per day) of capacity, the PureLine handles the demands of a busy household with ease.
Maintenance that looks after itself: Built-in filter-life indicators tell you exactly when the PPC filter (up to 12 months) or RO filter (up to 24 months) needs changing. When the time comes, the swap takes only a few seconds.
Peace of mind for the whole household: Particularly well suited to families with young children, older adults, or anyone with a weakened immune system — for those where water quality genuinely matters, the PureLine removes the uncertainty.
Product description
Tap water in the UK is safe — but safe isn't the same as great. If you've ever noticed a faint chlorine taste, wondered what's lurking in older pipes, or simply got tired of lugging home bottles from the supermarket, the Klarstein PureLine under-sink water filter is the straightforward answer. It sits hidden beneath your kitchen sink and delivers filtered drinking water straight from a dedicated tap, on demand.
At its heart is a 5-stage reverse osmosis system that filters down to particles smaller than 0.0001 microns — removing heavy metals, chlorine, bacteria, nitrates, and microplastics. The built-in TDS meter gives you a live readout of your water quality at any time, so you're never left guessing. Filter capacity runs to 800 GPD (approximately 3,000 litres per day), with a flow rate of 2 litres per minute.
Because the system is tank-free, it connects directly to your existing water supply and waste pipes — nothing on the worktop, nothing cluttering the cupboard. Smart filter-life indicators take the guesswork out of maintenance: the PPC filter lasts up to 12 months, the RO filter up to 24 months, and replacing either takes only a matter of seconds.
It's a particularly sensible choice for households with young children, elderly family members, or anyone with a compromised immune system. And for anyone who currently buys bottled water regularly, switching to the PureLine could save several hundred pounds a year.
Get yours today and start drinking tap water you'll actually enjoy.
