Which is the best reverse osmosis system?

I hope this article will help give you a little more information on Kinetico's K5 range of water filtration systems from an engineer's perspective. Someone out in the field with hands on experience installing a maintaining a large range of these water treatment products for the home and workplace on a daily basis.

Kinetico K5 vs .....

Ohio based water treatment giants Kinetico have a range of drinking water filter systems available to the UK market which include their tried and tested K5 range of reverse osmosis systems. The K5 is Kinetico's flagship reverse osmosis system offering a fully customisable multi-stage filtration unit designed to be installed neatly underneath the kitchen sink. Easy to use and maintain with exceptional recovery time, the K5 can consistently deliver large volumes of very high-quality water.

Features include

  • 5 different cartridge options (independently certified)

  • PureMometer display shows remaining filter life.

  • QuickFlo water on water tank technology to ensure a solid and steady flow

  • Patented and exclusive Ever Clean Rinse extending the life of the membrane.


Kinetico K5 filter system

The Kinetico K5 is available in three different

models - K5 Pure, K5 Pure Plus, K5 Pure Ultra


K5 Pure - The first and least expensive model in the range is the K5 pure. Supplied with the high-capacity carbon/sediment pre filter, taste & odour post filter and membrane, these form the basis to all of the K5 range. Utilising the same chassis as the higher end models, the K5 pure's additional ports allow you to upgrade your current system to the pure plus or pure ultra at any time.


K5 Pure Plus - In the middle we have the best-selling model out of the three, the Kinetico K5 pure plus. Similar to the K5 pure, the pure plus contains an additional reminerilisation cartridge containing calcium designed to increase the pH level producing delicious tasting water.


K5 Pure Ultra - Two additional cartridges include the Purefecta Guard and VOC filters which remove up to 99.99% of viruses and 99.99999% of bacteria.


How much does the Kinetico K5 cost?

RRP on the K5 reverse osmosis range from £655 to £880 inc VAT.



What is the best reverse osmosis system?

I've been installing many types of drinking water systems for now over 20 years and have found Kinetico's K5 and their other reverse osmosis systems to be top of the tree when it comes to pure water filtration. Tried and tested with some of the early KRO & KRO+ models still out in client's homes working away, water filtration from Kinetico has been pure-fected.

Here at AllSalts, we offer a full supply and installation service covering Essex, London, Kent and South Hertfordshire. Some of my areas include Romford, Colchester, Southend on Sea, Epping, City of London, Bexleyheath to name a few
