Domestic Water Purifier: are they really needed?


Do you really need a drinking water filter at home? Domestic water filters for human consumption are more of a fashion than a necessity, given that the purification process allows for water with a healthy, safe and controlled composition, and therefore already drinkable.

We live in UK and, in terms of water resources, we are one of the richest countries in good quality water in all of Europe. We are also in the Metropolitan City of Milan, where in addition to being able to count on water reserves in the underground aquifer that provide water of excellent quality, we have the advantage that the management of the aqueduct follows the Water Safety Plan. , the criticality control and forecasting procedure which aims to ensure its users drinking water, safe and healthy.

The drinking water filters must still be kept clean, to avoid the risk of water contamination. So let’s see together why a water purifier at home is not needed for human consumption.

Function of domestic water softeners:

Domestic water softeners mainly use technologies based on mechanical filters, activated carbon, separation membranes for micro filtration or reverse osmosis, disinfection systems with UV rays, carbonation and electrode ionization.

In practice, they have the purpose of softening drinking water and eliminating chemical elements and suspended particles which, through the drinking water treatment and groundwater analysis system, have already been eliminated by the water system manager, who at the same time guarantees periodic controls on microbiological, chemical and physical parameters provided for by Legislative Decree 31/2001.

It is also necessary to consider the fact that the drinking water that comes down from the tap has already been checked, the possible treatment of drinking water in fact varies according to the composition of the groundwater which is not always the same, but varies according to the territory .

Using a water softener for drinking water, already suitable for human consumption, can be counterproductive because it deprives it of essential mineral elements. So what is the purpose of using water softeners?

Reduction of the fixed residue:

True, even the most common filter jug ​​decreases the amount of minerals, with the result of making drinking water less rich in essential nutrients and with a lower fixed residue. Using a water softener, however, could have negative effects on our body! Mineral elements, and in particular magnesium and calcium, have a protective effect on the cardiovascular system and contribute to the prevention of osteoporosis. In fact, drinking distilled or demineralized water for prolonged periods, which has a fixed residue equal to zero, is harmful to the body.

Research and scientific studies confirm that excessively lowering the fixed residue in the drinking water is not healthy. The filter jug ​​at the limit can be useful for changing the taste of water, but if the purpose is to lower the fixed residue to protect one’s health, the effects will be null if not contrary.

Remember that sweetening the water too much is absolutely not good. On the other hand, if the fixed residue of your water is high and the water is rich in limescale, the concern must rather be directed to household appliances and not to our body!

Lower water consumption:

Are you really sure? According to an investigation conducted by Altro consumo, to have 1 liter of softened water with some domestic systems, a good 3 liters of water would be required, and moreover already drinkable. A decidedly high consumption, especially for such a precious asset as water. An asset that will be increasingly valuable in the future, due to the increase in population and the progressive thinning of the world’s water resources, a problem of the potential scarcity of future water resources.

UK has the great fortune of being able to count not only on quality water resources but also on one of the strictest systems for monitoring and distributing drinking water. In fact, the CAP Group manages the aqueduct system following a control and analysis protocol that ensures quality and safe drinking water throughout the water supply chain from the groundwater to the tap.

Guarantee of bacteria-free water:

True, but only if you remember to check the tap water filters and change them regularly, otherwise the risk is that bacterial colonies will form. Poor hygiene and care in a domestic water purifier therefore favors an increase in the bacterial load. The regulation on such devices also emphasizes this aspect, focusing on the importance of informing the consumer about this potential risk.

It is advisable that those who sold you the water purification system also provide ongoing assistance and maintenance. Even with the most common filter jugs you have to be careful and clean them regularly to avoid encrustations and favor the proliferation of bacteria.

Of course, the advice is also extended to the final container: you must also be careful with reusable glass or plastic bottles. Bottles and caps must be washed well because bacteria could proliferate even on rubber, glass and plastic. The water must be kept in the fridge and consumed within a few hours.

Elimination of chlorine, production of sparkling water and less pollution
Let’s see together if there are any real advantages. Remember that chlorine evaporates by itself, leaving the drinking water to deposit. If you prefer sparkling instead, a domestic carbonator is an excellent solution, but we remind you that in water houses now widespread all over the world you can also choose sparkling, safe, healthy and good drinking water.

As for pollution, it is not the domestic water purifier itself that pollutes the least, but the fact that it uses tap water and not bottled water.

Drinking water is by definition suitable for human consumption since by law it follows strict procedures of analysis and control of its composition which are used to guarantee its potability through procedures that verify its compatibility with defined microbiological, chemical, physical, indicative and emerging parameters by law and the WHO (World Health Organization).

CAP Group, specifically with the adaptation to the Water Safety Plan (PSA), or Water Safety Control (WSP), follows an innovative process of prevention and monitoring of procedures through risk assessment and management. A guarantee for your health that the manager signs with its users and certifies in each bill with the water identity card.

Purifying drinking water makes little sense, it is a waste of money and also of a precious commodity such as water. The water service manager ensures you safe and drinkable water by strictly engaging in the management of the aqueduct in your area every day, from the water table to the tap in your home.
