Adding a Filter System - Your Options

As we are specialists in water filtration, you have plenty of viable filter kit options to add to your 3-way tap, ranging from the simple to the advanced. Here is a quick summary of options which you can add to your purchase. Click on the links below to find a solution for your water concerns:

In-Line Systems

In-line systems offer a very user-friendly experience for someone having a specific issue with their water, whether this would be reducing chlorine in the water, or looking to remove scum on their hot drinks, we are highlighting two unique under-sink kits to tackle common issues found in water.

Osmio Ultra-Pure 3 Way Tap Filter Kit: A great but simple inline system which utilises a top-of-the-line carbon block filter cartridge for chlorine, taste, odour and sediment reduction whilst maintaining good pressure from incoming water.

Osmio Ultra-Soft 3 Way Tap Filter Kit: If you are experiencing build up in your kettle, the first step to moving towards a simpler, cheaper solution than new appliances is our Ultra-Soft 3 Way Tap Filter Kit, reducing the build-up of limescale and addressing the scum in your hot drinks.

Osmio Ultra-Ceram 3 Way Tap Filter Kit: Not recommended if your pressure is very low, minimum 2 bar. Uses a 0.2-micron ceramic layer for microorganisms and top-level performance for heavy metal and chemical reduction parameters.

Reverse Osmosis Systems

If you are looking to delve into an advanced water filtration system, which would indicate that you're looking for the purest water available and want to go beyond bottled water quality, providing crystal clear ice cubes, scum-free tea and coffee and clean and crisp drinking water. The range of systems we have put together was designed to provide safer, healthier water. Just as we offer a wide range of in-line systems we offer a wide range of Reverse Osmosis Systems additionally ranging from our premium economy models to our top-of-the-range systems.

Osmio HT+ Home & Office Direct Flow Reverse Osmosis System - If you have a large household or just really need an installed system for your home or office, then the Osmio HT+ Home & Office Direct Flow Reverse Osmosis System is a super option and represents the great value. The system produces about 1 litre per minute on average (it varies according to incoming pressure) but the flow is pure and freshly made through all filters. This can save an average of 10,000 litres of water per year and avoids the build-up of bacteria and biofilm and stinky tank water with no tank maintenance. The days of tank-based RO systems are over! Join the smart technology community and enjoy a slower but purer flow on tap with much better hygiene and environmental friendliness The neighbours will be jealous!

Can the temperature of filtered water tap be changed please?
Question by: Liene on 23 May 2023, 22:16
Our inline water filter systems and three way tap, filtered water feeds are only designed to supply ambient temperature (cold) water. We do have the Osmio Zero and Osmio Fusion reverse osmosis systems which can both dispense ambient, warm, hot and almost boiling water from their inbuilt dispensing nozzles.

What is the diameter of the lock nut and how close to an under mounted sink can the Bella 304 be mounted on a quartz worktop? Are the mounting details for the Fabia 304 exactly the same as for the Bella 304.
Question by: Eddie on 13 Aug 2021, 23:13
Both taps require a 35mm opening and can be mounted onto a quartz/ granite worktop. Both taps are mounted in the same way.

this is to replace a broken Brita tap, will my old (in line) Brita filter fit?
Question by: Mike on 28 Feb 2022, 10:26
Hello, it depends which type of Brita tap and filter kit you have, some of the older style systems were pressurised and designed to fit to a Brita three way tap that had four ports on the bottom (our three way taps have three ports). Please contact us with images of your current tap/filter kit by emailing info@osmiowater.co.uk or call us on 0330 113 7181 so we can further assist you.
