Better-tasting water

Enjoy fresh, clean-tasting water straight from the kitchen tap with advanced reverse osmosis water filtration technology.

Long lasting RO filter

Our patented EverClean® Rinse technology prolongs the life of the reverse osmosis membrane and ensures consistent high-quality water at home.

Excellent water flow rate

The K5 Pure water filter outperforms many filter systems from other brands with its unique QuickFlo® tank technology, ensuring a strong and steady flow of water from the tap.

Simple and easy to install

The K5 Pure home water filter fits easily and neatly under the kitchen sink and doesn’t use electricity so there’s no need for power sockets or electrical wiring.

Highest quality standards

All Kinetico home water systems are engineered for lasting performance and complete peace of mind – backed by a 10-year parts warranty.

Filter monitoring system

The K5 Pure is fitted with a PureMometer® – an easy-to-read metering system that prevents having to guess when the filter cartridge needs changing.

Non-electric water filter

Powered solely by water pressure, the K5 Pure water filter ensures there’s no electricity or cables to worry about, nothing to programme, and overall lower running costs.

Outstanding customer support

From installation to dedicated aftercare, we’ll ensure your Kinetico water system is always supported, kept in perfect condition, and performing at its best.

Why you’ll love it

Microplastics and PFAS removal

The K5 Pure has been independently certified by the Water Quality Association (WQA) to NSF International’s ANSI Standard 58 for PFOS/PFOA removal to remove 99% of PFAS. Known as ‘Forever Chemicals’, these man-made chemicals break down very slowly and can lead to a host of health problems when consumed. They are commonly found on non-stick cookware, waterproof fabrics, and certain food packaging.

With a K5 Pure water filter, you can trust your home drinking water with the knowledge these chemicals have been safely removed.

Why you’ll love it

Reverse osmosis filter technology

Enjoy Pure Water.

The K5 Pure uses an advanced filtration process known as reverse osmosis, where water is pushed through a semi-permeable membrane to trap contaminants. The result is crystal-clear, delicious-tasting drinking water straight from the kitchen tap, whenever you want it.

Why you’ll love it

Customisable water filters

Exceptional Performance.

With pre- and post-filtration cartridges already included with your K5 Pure, you can further upgrade your system for multi-stage filtration by adding additional cartridges. These can be added at any time to target specific contaminants – perfect if your needs change or you move home.

The K5 Pure water filter is typically installed under the kitchen sink, allowing for pure, clean-tasting drinking water directly from the kitchen tap.

Installation is carried out by a trained Kinetico professional with the plumbing expertise to fit your water filter correctly. Beforehand, a Kinetico expert will visit your home to assess your plumbing and ensure everything is ready for a smooth installation on the day.

The process is usually quick, though exact timeframes can vary depending on the complexity of your plumbing.

Find out more about our installation process

We recommend routine maintenance and sanitisation of your Kinetico K5 Pure water filter to ensure it continues to operate at optimum performance.

The lifespan of each filter cartridge will vary depending on household water usage. For an average family of four, the typical lifespan is around 9–12 months. The pre-filter cartridge, taste & odour cartridge, and any auxiliary cartridges should be replaced annually, or sooner if the filter timer indicates.

Before carrying out any maintenance, ensure your hands are clean. For complete peace of mind, we suggest having a Kinetico service engineer perform a professional filter change and sanitisation.

If replacing the filters yourself, please follow the instructions in the user manual. Always wash your hands before handling new water filters and avoid touching the internal parts. After installation, flush the system by running a full tank of water through the tap, and carefully check for any leaks.

Why do I need a K5 Pure water filter?

Even treated tap water can contain hidden impurities that affect its taste and quality – the K5 Pure water filter is designed to refine your drinking water so it’s perfectly filtered the moment it leaves your tap. By helping to remove unwanted substances such as chorine, microplastics, heavy metals, and PFAS, every glass becomes cleaner and more enjoyable.

Unlike standard filter jugs, the K5 Pure provides a continuous supply of high-quality filtered water, without the need for refilling or waiting. It’s a more convenient, higher-performance solution for everyday use – whether you’re drinking, cooking, or making tea and coffee.

And because the K5 Pure is fully upgradeable, you can enhance your system at any time with additional filter cartridges.
