Whole house water filters

If you are considering installing a water filter in your home you have a choice between using one or more point of use filters (POU) or installing a point of entry (POE) whole house water filter system that will provide filtered water throughout the entire household and where water for consumption is the only concern an undersink or countertop water filter would represent a perfectly adequate solution, with a wide choice of filter system able to remove a comprehensive range of undesirable contaminants, POE is definitely better, albeit the more costly.

PoE provides clean, safe water for washing up, baths, showers and perhaps washing machines, dishwashers etc and any system should include:
– Wide Choice of filter types – options for specialist cartridges for difficult to remove contaminants such as chloramine & fluoride and broad spectrum impurities, such as chlorine, VOCs, bacteria, cysts, herbicides, pesticides, heavy metals such as lead.
– Filtered Water throughout the home with no need for separate POU filters saving money and time on maintenance, although only applicable if you don’t have tanks.
– High Flow Rate – whole house filters must allow the flow rate to be tailored to demand.
– Reduced Limescale – any of the filters available must reduce scaling thereby preventing damage to appliances.
– Cost Effectiveness – having a single point of filtration for the entire premises is cheaper than installing multiple separate filters.
– Adaptability – the use of stand sized housings must be catered for, but always allow for an additional room or two.

Which Whole House Water Filter System Is Right For You?
The ideal starting point for answering this question is to have a water test done. This will give an accurate indication of what contaminants are in the water, its hardness (pH) and whether there is a need for specialist micro-organism treatment, this being more likely where there is a private water source such as a well.

The second important consideration is the required flow rate. On the one hand you would not want to pay for a larger capacity system than you need but neither would you want to constrict your water use with one that’s too small for your homes requirements.

Some of the Whole House Filter Types Available include:

  • Sediment only filters – Useful when there’s a problem with sediments and particulates as might occur when the water supply is from a peat laden source for example. These are graded according to the size of particle they will remove which is expressed in microns (a micron is 1:1,000,000 of a metre. a strand of hair is about 100 to 150 micrometers wide).VThe largest generally being 50 microns and the smallest l micron although the NanoCeram cartridge filters down to 0.2 micron. Mosts cysts are larger than 1 micron so a sediment filter would be effective for this issue but needs to be a ‘1 micron absolute’ to guarantee effectiveness.
  • Chlorine, Taste & Odour Filters – Often the main concern of someone wanting to filter their home water is chlorine and rightly so. No one wants to drink or bathe in water smelling & tasting like a swimming pool. There are also health implications associated with the long term ingestion of chlorine and with breathing in chlorine vapour in the shower. Filters of this type generally employ carbon, either as a block or as granular activated carbon (GAC) and represent an affordable solution to the chlorine problem. Such filters may also include KDF (Kinetic Degradation Fluxion) which furthers removes chlorine. These filters achieve a very high removal rate for chlorine, normally 99.99%+ however it is important to be aware of the issue of chloramine (chlorine+ammonia), increasingly used in conjunction with chlorine which is not removed efficiently by standard carbon filters and requires a more specialist type to be used. Check with your water company whether they use this chemical in the treatment plant.

Comprehensive Multi Housing Filter Systems
The filters of choice where it is desired to remove the widest range of contaminants possible. Often comprised of two or even three filter housings these systems can also be the most expensive choice. One major advantage is that they allow the inclusion of specialist filter types eg. for chloramine or fluoride as well as those that will remove a broad range of impurities such as chlorine, pesticides, herbicides, hormones, VOC’s, hydrogen sulphide, cysts and protozoa and heavy metals including lead, with some types notably those using Active Ceramic media being able to additionally reduce limescale. Such filters include systems such as the Osmio PRO-III-XL Ultimate Whole House Water Filter System which includes an Active Ceramics, a carbon with KDF and a granular activated carbon filter which will give the best possible home water.

Other systems such as the Osmio Pro-II-Advanced system will also remove a huge range of impurities and includes the Active Ceramics filter with the second housing containing a 5 micron carbon block cartridge.

  • Active Ceramics
    A brief explanation of the amazing Active Ceramics filter media may be helpful. This is a relatively new type of filtration media which employs 4 differing types of ceramic balls each with specific filtering properties. AC media will remove very many impurities including chlorine, toxins, heavy metals, hormones and fluoride. This filter is also highly advanced and effective at killing and containing bacteria in water such as E-coli, Pseudomonas and other microorganisms. A further benefit of Active Ceramics is that it raises the pH of the water and adds antioxidants and minerals back into the water further increasing the water’s health giving effects. The apparent downside of active ceramic cartridges and the systems employing them is the initial cost, making it seem an expensive investment, however it needs to be borne in mind that Active Ceramic cartridges have a life span of 2 to 3 years making them in fact a very cost effective option.
  • Ultra-Violet Disinfection Systems
    Strictly speaking these are not filter systems as they do not of themselves remove anything from the water. What they do is to kill any and all micro-organisms that may be present, and they do so very effectively. Ultra-violet light is lethal to the pathogens found in water and is a certain way to ensure freedom from biological contamination of your water supply. They will destroy cysts, bacteria, protozoa and even viruses ensuring that your water is biologically safe. To work effectively however it is vital that all sediment has been removed from the water first as the micro-organisms can in effect ‘hide’ in the sediment particles and not receive a proper dose of UV light. For this reason it is strongly recommended that all UV systems be installed with one or more sediment pre-filters.

Maintenance
The best water filter systems will become useless if not properly maintained. Fortunately this is not a difficult thing to achieve. Normally all that’s necessary is timely filter changes. Working out when a filter change is needed is not an exact science however and will depend on many factors such as the type of filter, sediment levels, the total volume that has flowed through the system, pH and water contaminant levels. Generally they should be replaced at the recommended minimum time intervals but if the incoming water is not too bad this may be extended a little. A very useful addition to the system is to include a simple water meter with your installation which will let you know the exact volume of water that has been filtered and makes calculating filter changes more accurate. An isolating valve is very useful when changing or maintaining your filter and it is recommended that one or more be fitted at the time of installation.
