Hasloc was founded with a simple mission: to make cleaner, more affordable filtered water accessible to everyone. At its heart is founder, John Courtney, who has spent over 25 years creating smart, sustainable solutions that deliver bottled-water quality straight from the tap. After pioneering one of the UK’s most widely adopted under-sink filter systems, John set out to solve a problem that has been bugging him for years – common under sink filters waste filters and money by cleaning all the water that flows through your kitchen tap. John’s breakthrough? A smarter filter that only purifies the water you actually drink—maximising efficiency, cutting waste and saving households money. 

SmartQuench™ is the UK’s smartest on-demand tap water filter. Using the latest in wireless technology, it has a button activated system so it only filters water when you need it. One press and the filter removes chlorine, microplastics, forever chemicals, limescale, and more. By only filtering water when you want to drink it, SmartQuench™ maximises the filter's performance and reduces costs, delivering filtered water on demand for just 11 pence per day. There are two filter options to choose from and five different button colours available so you can match the filter to your water and the button to your existing tap.
