Drinking Water Filter Comparisons

Helping You Easily Choose Your Drinking Water Filter System

The following table compares several of our most popular and highly recommended drinking water filter systems for the removal and reduction of various impurities as well as unique product features.

There are several options available, including portable/zero installation systems as well as systems which are installed under the sink/counter. There are also under sink filter systems which can be fitted to your existing kitchen tap (2-way tap tap supplying hot and cold water), meaning no need for a separate tap or a 3 way tap.

Use the table below as an easy way to choose your water filter system

* please note that the ticks in some cases do not necessarily represent 100% reduction as this is largely dependent on incoming water quality but can mean exactly this and an average minimum of 85% unless otherwise stated.  Filter change frequency can also vary depending on the nature and quality of water used for purification.


Tap Options

Selecting the right kind of tap is very important, not just from an aesthetic perspective, but also ensuring the most appropriate tap is chosen to ensure good working and adequate flow rates.


Keep your existing kitchen tap

We have a specific range of products which enable you to keep your existing kitchen tap (i.e. a normal hot and cold kitchen tap) and have the entire cold side filtered. These are the Osmio EZFITPRO range which have 15 mm push fittings, which enable either copper or plastic (speed-fit) 15 mm pipe to simply push into the inlet and outlet of the filter unit. This means all the water of the cold side will come out filtered. The advantage of this option is that you will not need a separate tap or a 3-way tap. The disadvantages are that all the cold water will be filtered.

Single Water Filter Taps

The taps are separate taps which dispense the filtered water only (also known as mono-block or 1-way taps). They are ideally fitted into the corner of a  normal stainless steel sink or in laminate or wooden kitchen worktops (or any worktop which is easily drill-able for a 12 mm hole and it can be accessed easily underneath to attach the nuts of bolts!). Many sinks already have an available hole (which is usually covered with a blanking cap) making it even easier to use a separate tap. Single taps can be a preferable option in a number of instances - where elderly or very young people could get confused as to which tap to use for filtered water or when it is changing the main kitchen tap for a 3-way tap is not preferred. Single taps are not recommended for stone, ceramic or composite sinks or if they need to go into worktops which are marble, granite or very expensive and difficult to drill through. Usually a very skilled plumber or specialist is required to drill through granite worktops, so in this instance a 3-way tap  or a "use your existing kitchen 2-way tap" option is recommended.

3-Way Taps

Three-way taps provide the most elegant solution for filtered water in your kitchen. They connect your existing cold and hot water as well as the filtered water through 3 separate connections on the base of the tap. 3-way taps are suitable where you have ceramic, stone or composite sinks or if you have a marble, granite or other expensive kitchen worktops.  3-way taps provide you with the most flexibility as you have an unlimited choice as to which filter system to go for. Before choosing a 3-way tap, you have to first know what type of hot water system you have because 3-way taps come in high pressure and low-pressure versions. If you have a combi-boiler/mega-flow, i.e. a pressurized hot water system, then you can choose from any 3-way tap we have on offer. If you have a hot water tank in the loft or upper floors of your home which is not pumped to the kitchen (i.e. the kitchen hot water is fed by gravity pressure alone) then you have a low-pressure system. If all this just sounds way too confusing, don't worry! Help is at hand - just call us free on 0330 113 7181 and we will advise you.
