The water filtering systems allow to purify it from all those substances potentially harmful for our body. Here are some useful tips for buying a water filter that fits your needs.
What is a water filter used for?
His name already explains it: in theory it would serve to make the water in the house coming from the tenant cleaner . In the past, and still today, there are many controversies concerning water filters that are sold to private individuals, to be installed directly on the domestic appliances of their homes. The controversies against these systems maintain that the purification of the water should be done upstream, or rather by the suppliers of water themselves. And that these filters do not serve much purpose.
The fact remains that today there are many water purifiers on the market that can significantly improve the quality level of this precious element. The purchase of bottled drinking water remains widespread in USA . Will it be safer?
According to recent surveys it has been discovered that while in the aqueducts that send water to our homes every day, the checks are done daily, the bottled water is examined every month: from these data it appears that it should be safer than the aqueduct .
Water that, treated with a good domestic purification plant, would guarantee considerable healthiness and savings , both in terms of the cost of bottled water and the disposal of plastic once it has been thrown away.
Different opinions, therefore, even with scientific data in hand, which make it difficult for citizens to choose: domestic purifier yes or no? Despite the safety of the plants, an additional obstacle to bacteria and pollutants can certainly not harm.
Let’s find out how a water filter works , the kind you can buy for your homes. In the next section we will analyze the various types of water purification.
Types
To purify and make the water we see coming out of our house tap safer, there are actually different methods, based on the problem encountered on a case by case basis. Here are the four main types of water purification:
Softening
This first type of water filter is used to make your water less calcareous. If the water rich in limestone, also called “hard” is not necessarily harmful to health, the same cannot be said for water systems and domestic appliances such as the dishwasher or condensing boiler . In fact, when heated, it forms limestone, which in the long run can ruin your electric water appliances. Water softeners are therefore a good choice for having less hard water and at the same time preserving appliances such as washing machines and boilers from the deleterious action of limestone.
Activated carbon
This system is able to purify water from various pollutants, such as chlorinated compounds, trihalomethanes and pesticides, which are very harmful to our health. Unfortunately, it is not able to eliminate nitrates, calcium and bacteria, which are equally harmful to our health. Usually they are connected directly to the tap in your home and, once the maximum saturation is reached, they must be replaced.
Ion exchange. As for water softeners, selective resins are also used for this ion exchange system to eliminate nitrates and metal ions. Apparently, however, they can do nothing against bacteria. Once the maximum capacity is reached, this system must be regenerated.
Reverse
osmosis Reverse osmosis is a process of physical filtration, which requires the installation of a particular appliance under your sink: we are talking about the reverse osmosis water purifier . The water passes through a permeable osmosis membrane that allows to separate the particles larger than water. The membrane must be constantly cleaned and after a quantity of uses must be replaced.
Physical filtration
It is a filter that is applied directly to the water source: it is a sort of sieve able to separate water from substances such as sand and iron. It is perfect for wells or fountains, but it has been found that it is not very useful for domestic water, for which more accurate purifiers are needed.
Specific types based on use
Carafe filters
They are better for filtering small amounts of drinking water, without the problem of installing a larger and more expensive domestic water treatment plant. The filtering carafes are sufficient to have for lunch or dinner lighter and clean water, as compared to that of the tap, and they work with filter cartridges that must be replaced periodically.
Faucet mounted filters
They work best to filter water for drinking and cooking with easy installation. Moreover they allow to pass from filtered water to unfiltered and vice versa. Among the disadvantages, they slow down the flow of water and do not work with all the taps.
Kitchen
countertops This option allows you to filter large quantities of water without modifying the pipes. It is also less easy for them to become clogged compared to carafes or filters mounted on taps, even if they can make the kitchen top untidy and cannot be used with all the taps.
Filters under the sink
These also allow you to filter large quantities of water without having to change the tap or make the kitchen top untidy. But they steal space in the cabinet under the sink and require piping changes. You will also need to make a hole for the dispenser through the sink and / or the kitchen counter.
Reverse osmosis filters
They can remove a wide range of contaminants, including dissolved solids, and are the only certified type for arsenic removal, but require modifications to the pipes and must be periodically disinfected with bleach. They are also extremely slow, stealing space in the cabinet and wasting 3 to 5 liters of water per filtered liter.
Filters for the whole house
They are an economical way to remove deposits, rust and, for some, chlorine from the house water. Their long life is another advantage, but most have not been created to remove all other contaminated substances, including cysts, metals and volatile organic compounds. They require a professional installation.
How to choose a good quality water filter
How can we choose the most suitable domestic water filter for our needs, to avoid excessive expenses that prove to be useless? Here are some practical tips to buy the most useful filtering system for our needs and the needs of our water system in complete serenity .
First of all, we need to make a thorough analysis of our situation and our plants, in order to better understand what our needs really are regarding the drinking water that comes out of our tap, be it a domestic system or a plant larger professional level.
We need to understand the conditions of the water that comes home from the aqueduct and understand what precautions need to be taken to avoid bacteria, diseases and pollutants.
Secondly, after having ascertained what our priorities are and what the conditions of “health” of our water and of the handlers arriving in our house are, we must ascertain what our needs are.
To choose the best product to buy, and avoid purchases that in the future may prove useless and unnecessary. If the problem is only limestone, then it is better to choose a softening system , which allows us to solve our only problem, without spending money on a device that performs other filtering. The activated carbon system can be useful , if your water is infected by pollutants that are not too specific: against pesticides it is perfect, but it is better to try something more “powerful” if the pollutants are also others.
Furthermore, another type of choice can be represented by the type of user that we must protect from too polluted or too unsafe waters. The basic systems are very useful for domestic users, while those with physical filtering, for example, are perfect for large systems, such as wells or fountains. While they would be completely useless for domestic users.
Where to buy
Once decided, and reflected in depth, on the filtering system that best suits our needs, we will need to contact someone in order to make our purchase.
In this case it is a bit complicated to find shops that sell this equipment: you can try to find out in stores that specialize in hydraulics or in some very well-equipped and very specialized hardware stores.
These are the tips if you need to buy filtering systems for domestic use, therefore with reduced dimensions: in fact, these systems are more readily available, without having to carry out searches in supply stores for wholesalers, perhaps for plumbers, where you will be assured to find the required equipment.
Another piece of advice we can give you is to contact your plumber , who, even if he is expert enough in terms of filtering water, will be sure of receiving excellent advice on where to buy the best products, which products to choose (the an expert’s advice is always welcome, when it comes to buying and installing products as specific as water filters can be in your own home or company: always to avoid costs that could prove useless and wrong in the future) and can also help you with the installation of the chosen system.
Another solution, if you want to proceed on your own, can be the DIY department store , always very useful in these cases if you decide not to consult an expert, even trying to save a little bit. If there is a section dedicated to hydraulics, in all probability there will also be easy-to-install solutions dedicated to water filtration.
