Specialist Filters

The selection fo filter cartridges available includes specialist filters for difficult to remove contaminants such as fluoride and chloramine, and which can be added in sequence with other filter cartridges such as sediment, carbon block, GAC and the highly effective Active Ceramics cartridges which have the added bonus of reducing limescale.

Nearly all the filter systems presented here will remove chlorine and will improve taste & odour.

Our whole house mains water filtration systems start from as little as £86 for the Osmio Sediment Filter up to the highly sophisticated Osmio Pro-111-XL Ultimate at £795.  Systems are available consisting of a single, double or triple housing arrangement depending on the filtration requirements.

As an option you may wish design your own combination of filter types using our whole house filter housings in combination with the most appropriate filter types for your specific water supply situation.

Capacity Considerations

Before buying a water filter for home installation, you will first need to consider the following:

1/ What do you need the system to remove from your water? For example it would not be necessary to purchase one that removed fluoride you are not in a fluoridated area. Are high sediment levels a problem? Are you experiencing problems with high limescale? Ideally the place to start is with a full spectrum water test.

2/ Where it is going to be situated and what size system will fit? Usually a whole house water filter system is installed where the rising main comes into your property, so that all the water can be purified by the system before the pipes divert around your house. In some circumstances they may be installed outside the property provided adequate protection against freezing is given.

3/ What size system is suitable for the size of your household? It is important to ensure that the system you are installing has the capacity to handle the average flow rate and also to take into consideration the theoretical maximum flow rate for your property which will depend on the household useage of the water supply. For help with calculating flow rate see here: How To Measure Your Flow Rate

We would strongly recommend that all whole house filter UK systems are installed with a bypass isolating arrangement for easy maintenance and change of filters.

Typical By-pass installation for Whole House Water Filters

Filtering the incoming water at entry means that you will not need to fit a separate under sink water filter or reverse osmosis water filter for your drinking water which makes a whole house filtration system a very cost effective investment which will bring satisfaction evertime you turn on the tap!
