Why do we need water filters

Water can contain dirt, minerals, chemicals and other impurities that make it taste and smell bad.  Some of these contaminants can endanger your health, especially when they include microscopic organisms and bacteria that can cause serious illness. Using a water filter can help purify water, removing these impurities and making it safe to drink, whilst also improving its taste.

SEDIMENT REMOVAL

Sediment is any particulate matter than is transported by water flow. These particles may be rust flakes from water pipes, sand grains, small pieces of organic matter, clay and dirt particles, or any other small particles in the water supply.  Carbon filters will filter sediment but dependant on the application and the level of sediment in the water consideration should be given to a dedicated sediment filter for pre-filtration.

LOWERING CHLORINE

Most municipal water utility companies use chlorine to treat drinking water because it's inexpensive, easy to use and highly effective at killing many of the bacteria found in water.  It can also eliminate some viruses.  Whilst it's a good disinfectant, chlorine can make drinking water smell and taste unpleasant, and it can react with some metals to form hazardous compounds.  An activated carbon filter removes the chlorine smell and taste from water.  The vast majority of filters contain carbon to suit many different applications such as fridge water filtersreplacement under sink filtersjug filterswater boiler filterscoffee and vending filters, and water cooler filters.

PESTICIDE AND CHEMICAL REMOVAL

Before the 1940's most common forms of pesticides contained heavy metals that did not readily dissolve in water, but today pesticide residue in drinking water may be on the increase due to the fact that modern organic pesticides dissolve in water and can get into the water supply.  Carbon filters can remove pesticides and volatile organic compounds from drinking water.

PATHOGEN REMOVAL

Filtering water is essential to keep harmful bacteria and parasites from drinking water.  Giardiasis is a type of illness that causes diarrhea and can last several weeks.  The microscopic parasite that causes this disease is Giardia Intenstinalis, an organism that can survive in the environment for many months.  It can be ingested from water that has become contaminated with animal or human faeces.  Another parasite that can cause similar symptoms is Cryptosporidium.  Cryptosporidium is resistant to chlorine and must be removed by filtration.  These pathogens are effectively removed by passing water through filters rated below 1 micron, there are a number of filters available like the AP2C405SG, Everpure 4H and BH2 filters, and the Doulton range of filters with patented ceramic candles.

REMOVING HEAVY METALS

Heavy Metals can be very harmful to your health if found in your drinking water.  Heavy metals such as lead, mercury, aluminium, copper and arsenic can have severe effects including reduced growth and development, cancer, organ damage, nervous system damage and in severe cases death.  Lead is common where it seeps into the water supply from old plumbing pipes or the solder used to join them together.  Lead is toxic when ingested, and it is essential to remove it from drinking water.  It can be removed from water through reverse osmosis filters and carbon filters designed specifically to remove heavy metals like the Doulton Ultracarb and ATC Super Sterasyl cartridges

FLUORIDE REMOVAL

Water fluoridation is the addition of chemical fluoride to the public water supplies for the purpose of reducing cavities.  Is fluoride bad for you? it depends who you ask as fluoride is unquestionably toxic at certain concentration levels.  Municipal water utility companies say that the level at which it is added to the water (around 1ppm) is safe and effective.  Doulton's fluoride removal filter is manufactured to reduce fluoride levels within drinking water.

SCALE REMOVAL

Scale (or lime scale to give it it's proper title) is the hard chalky deposit that forms on the end of taps and in pipes as well as on the heating elements inside kettles and boilers.  It is composed mainly of calcium and magnesium carbonate and it can range in colour from white to dirty brown.  You will also notice a scum or film on the top of tea and coffee where this problem occurs. Once scale has formed it is very difficult to remove and requires the use of an acid de-scaler to dissolve it.  In worst case scenarios you may have to replace your equipment.  Scale can also be extremely detrimental to catering equipment such as ice machines, coffee and espresso machines, steamers and dishwashers as well as wall boilers.  Scale build up on the heating coils and evaporator plates of these machines causes them to run inefficiently or, worse still, can cause maintenance problems and breakdowns often running in to thousands of pounds.  Beyond water system efficiency and potential damage to any equipment, the taste and appearance of a hot beverage can be affected as the extraction of flavours may be altered with hard water and clear drinks may become cloudy or have surface scum.  Filtration solutions range from carbon filters with scale inhibitor media such as the AP2C401SG and AP2405SG filters for Lincat water boilers, H11MC water filter and the Insinkerator  replacement cartridge right through to filters dedicated for scale removal for coffee, vending and ice machines.
