Why treat your kitchen drinking water.

Tap water may differ in organoleptic characteristics and composition from that distributed by the aqueduct due to the alterations that occur in the pipes. The main cause of deterioration in water quality is the release of unwanted substances from pipes, a more common problem in private pipes inside buildings. In old buildings, poor water supply can lead to contamination of the water with dangerous metals such as iron, lead and copper, especially when the water remains stagnant in the pipes for a long time.

Residues of disinfectants, such as chlorine, used to ensure microbiological safety, can react with other substances in the water and form unwanted by-products that degrade water quality.

To improve it, there are various solutions that can make it good, light and healthy.

Water filtration systems.

If you are not completely satisfied with tap water because it does not taste good or because it may contain unwanted substances (such as contaminants, microplastics or heavy metals), but you want to stop buying bottled water, there are several ways to improve the drinking water in your home. Each method is effective in its own way and treats water differently to make it pleasant to drink.

Let’s see the most popular domestic water filtration systems and which ones you can orient yourself on.

Filter jugs use resins and activated carbon to improve the water. They are quite effective, but they don’t work miracles!


  1. they reduce the hardness and nitrates present in the water
  2. they improve both the quality and taste of drinking water
  3. the cost of management and maintenance is quite low.


  1. they cannot solve water contamination problems.

Filters are compact devices that connect directly to the faucet.
Inside a cylinder is a filter cartridge that purifies the water every time the tap is opened.


  1. They improve the taste of drinking water by eliminating chlorine compounds
  2. Eliminate sediment


  1. The cartridge lasts approximately three months
  2. They do not modify other aspects such as hardness, conductivity, nitrates and metals present in the water

Usually installed under the kitchen sink, they can consist of a single composite filter or a series of filters. The first filter captures larger particles, similar to those that accumulate on faucet aerators (pebbles). The second activated carbon filter eliminates the bad taste of the water.


  1. They effectively eliminate the taste of chlorine
  2. They retain organic particles and some heavy metals
  3. They have a relatively low cost, compared to other filtration technologies
  4. They are easy to install


  1. Activated carbon becomes easily saturated and must be replaced approximately every 6 months
  2. It cannot eliminate nitrates, some bacteria and heavy metals, pesticides, viruses, etc
  3. Bacterial microflora can grow on activated carbon, which could make the water unsafe to drink

Home water purifier.

Domestic water purifiers are devices that guarantee the purity of the water we use daily in the kitchen for drinking and cooking.

These devices improve the quality of drinking water, eliminating impurities, odors and unwanted tastes. Smooth, carbonated and cold, with the home purifier you can have the water you prefer, with the possibility of customizing the taste by setting the quantity of mineral salts.

Regardless of the model, the operating principle of a home water purifier focuses on the removal of impurities present in the water through a filtration process.

The water coming from the water supply enters the purifier through an inlet pipe and passes through the filter, which can be made up of different layers or materials depending on the type of purifier. The main types of filtration have an activated carbon pre-filter, which absorbs chemicals and odors, and osmotic membranes, which remove even the smallest particles and heavy metals.

The treatment method of water purifiers is mainly divided into three

  • Microfiltration: microfiltration systems are the most economical and ideal for removing unpleasant odors and flavors, particularly suitable when the water is already of good quality and light. They retain particles with a diameter between 0.05 and 10 μm (microns)
  • Ultrafiltration: ultrafiltration purifiers offer average effectiveness and cost, managing to eliminate even chemicals and bacteria down to 0.01 micron
  • Reverse osmosis: reverse osmosis purifiers are the best performing; thanks to special membranes, they can remove pesticides, herbicides, nitrates and nitrites, arsenic, lead ions, pesticides, heavy metals and other particles up to 0.0001 micron

Which water purifier to choose?

When we have to choose a water purifier, it is essential to carefully evaluate which product is best suited to our needs and what type of water reaches our homes.

In this regard, it is important to remember the contribution offered by Better Life in tackling the threat of PFAS. The Venetian company, specialized in water purifiers, has developed a reverse osmosis filtration system which represents a concrete solution to the problem of PFAS. In Veneto, worrying levels of PFAS have produced serious consequences on the health of the local population. Scientific studies have highlighted how PFAS can cause liver damage, thyroid disease, fertility problems and cancer.

The Better Life filtration system has passed rigorous laboratory tests, obtaining accreditation from the magazine “Il Salvagente” for its effectiveness. This advanced filtration system therefore represents an important ally for our health.

Only a few companies have received the prestigious “Zero Fraffe” recognition and they rank among the most serious and reliable, appreciated by customers for their reliability, contractual transparency and, naturally, for the quality of the products, patented and produced in Italy. This can help us further narrow down the choice among the best available on the market.

The water purifier, therefore, presents itself as the most reliable tool for those looking for pure and safe water at home, perfect for drinking daily or for preparing meals for the whole family. Furthermore, the purifier helps reduce the production of plastic waste, thus contributing to the protection of our planet.
