There are many systems on the market but the reverse osmosis purifier is certainly the safest and most efficient.
Filters and water purifiers: never more bottled water
As much as environmental experts and associations continue to defend the quality of the water coming from most of the USA aqueducts, thanks to the regular checks on the chemical and bacteriological level carried out by the managers and local ASLs, there are still many people who opt for the purchase of bottled mineral water.
This bad habit, fortunately less and less widespread, in addition to leading to an increase in waste potentially polluting the environment (whether plastic or glass), appears increasingly expensive and impractical . In fact, due to the increase in transport costs , the cost of buying bottled water has grown considerably over time and to mitigate this increase in cost, one often has to store large stocks of water purchased at home special offers periodically offered by various discount stores and supermarkets.
The smart alternative to bottled water
Fortunately, in recent years other systems have spread, from carafes to purifying filters , up to the reverse osmosis water purifiers , very different from each other. Pros and cons will be considered in the following lines. Filtering pitchers (or pitchers) are the most common water filtration systems. Their diffusion has certainly been favored by the price within everyone’s reach. They are mainly based on the presence of activated carbon filters , an element known for its ability to retain only chlorine and bad tastes .
Activated carbon is also often added to a percentage of ion exchange resin , useful for intervening in water hardness. However, filter jugs have some negative factors. First of all, the water that stagnates inside the jug is likely to lead to the proliferation of bacteria , especially when the filters do not contain compounds based on silver salts. Furthermore, discontinuous use and non-regular replacement of the same filters can lead them to release potentially harmful substances. Criticisms concerning the excessive increase in the levels of bacterial charge, potassium and sodium by carafes are not rare .
The activated carbon filters, the latter are useful especially when the water coming from the aqueducts has a strongly marked chlorine taste . Just the chlorine is used during the purification in order to avoid that the passage inside the pipes contaminate the water from viruses and bacteria .
In addition to retaining chlorine, the filters are also effective against various organic pollutants . However, they cannot eliminate nitrates , arsenic, bacteria and do not have the slightest influence on most pollutants and undesirable substances often found in water. Furthermore, these devices have very small holes, so that sometimes only a few liters of water are needed to fill them; this makes frequent spare parts and maintenance operations indispensable .
Reverse osmosis: the best technology for water treatment.
In recent years, reverse osmosis purifiers have become increasingly widespread . Installing a water purifier with this technology in your home allows you to have an ideal filtration system in keeping almost all of the salt content in the water. In this regard, we are talking about a percentage of dissolved substances between 90 and 99.9%. The adopted technique, reverse osmosis, is mechanical and therefore does not add any chemical substance to the water .
The water is conducted, exerting an increase in pressure, through a special semipermeable membrane . The latter allows only a small part of mineral salts to pass, removing all the possible polluting and unwanted substances . Furthermore, the latest generation reverse osmosis water purifiers are equipped with a special deacidifying and re-mineralizing post-filter with natural calcium carbonate able to rebalance the right concentration level of salts dissolved in water. In this way, it will escape from your faucet only pure water of high quality mineral, characterized by a low dry residue, then slightand extremely pleasant taste.
