Has LAICA compiled with all legal obligations concerning filter pitchers?
Yes, LAICA has compiled with all legal obligations. The Ministry of Health and the ISS have been given detailed information with all the technical and scientific documents, laboratory trials and the validation tests for Laica filter pitchers.

Are the LAICA pitchers safe?
Yes, LAICA pitchers are safe as specifically established by Section 111 of the ISS Council on June 14, 2011, when it reached the conclusion that: “on the basis of the scientific evidence available today there are no negative effects on health deriving from the use of the filter pitchers”. Furthermore, this fact has been confirmed by the most authoritative and prestigious international certifying bodies, to which LAICA submitted the evaluation of its filter pitchers.

Are SODIUM and POTASSIUM harmful?
No, sodium and potassium are mineral salts essential for the good working of the body’s metabolism. The LAICA filter pitchers cause no significant variation to the level naturally present in the drinking water.

Is it good to eliminate/reduce hardness?
The hardness in drinking water is very important for the absorption of calcium and magnesium (water is a better vehicle than other foods). Important clinical studies validated by WHO and the ISS confirm that water containing calcium and magnesium salts (hardness) has a protective function in the prevention of cardio-vascular diseases.

Can hardness cause kidney stones?
No, it cannot. In actual fast, there is no relation between calcium, magnesium and the onset of kidney stones.

Why does pH have to be balanced?
A balanced (i.e. neutral) pH is preferable to a low (acid) pH because not only does the water taste better, but it also helps to create an alkaline environment in our bodies. An alkaline environment gives protection from degenerative diseases which tend to develop in an acidic environment. Furthermore, clinical studies have shown that treatment with water of alkaline pH can be useful complement to the therapeutic management of functional digestive syndromes.

Do LIACA pitchers release ammonium?
No, the LAICA filtering system releases no ammonium, as proven by numerous laboratory analyses. Ammonium is not a health element and at certain concentration levels is certainly harmful; it is better, therefore, that the pitcher does NOT release ammonium.

Can the filter cartridge release what it has retained during use at end of its life?
No, the Bi-Flux™ filtering cartridge retains the filtered impurities even beyond its useful lifespan. These impurities are fixed by chemical and ionic bonds which do not allow them to be released.

Does boiling the water help to reduce the chlorine and heavy metals?
No, boiling the water does not help. In fact, heavy metals do not evaporate. While chlorine does evaporate, its more dangerous derivatives, such as trihalomethanes, resist the boiling temperature of the water.

Why do you need to wash the pitcher regularly?
Because even filter pitchers should receive the same cleaning care used for any kitchen implement (such as plates, glasses, containers, etc.)

Should the cartridge be washed?
No, the cartridge should just be rinsed under running water (without using detergents) when the pitcher is washed.

If I go on holiday for a week or more and the cartridge has not finished its lifespan, how do I conserve it?
It is recommended to wash the pitcher with water and dish detergent, rinse the cartridge under running water, leave it to drain carefully, and then put it back in the pitcher. Before you leave, make sure everything is placed back into the fridge. Before re-using it, carefully rinse the cartridge under running water.

What is Silver for? Can it be harmful?
Silver prevents the growth of bacteria once the chlorine has been removed. The derivatives of chlorine are harmful for health; Silver, on the other hand, is not harmful to the extent it is used (following the WHO and Health Ministry guidelines).

Why does the flow of water often slow down and then suddenly get blocked?
Inside the filtering cartridge air bubbles can sometimes form, which act as pressure plugs, preventing the water flowing evenly. To restore normal functioning of the filter just remove it, and immerse it in water, making the bubbles escape. Then let it drain and then reinsert the filter into the pitcher .

Do I have to keep the pitcher in the fridge as indicated in the instructions?
Like all foods, even water keeps its characteristics (organoleptic, pH, flavour and smell), more safely if it is kept at the usual temperature of a fridge. However, all microbiological analyses carried out at 72°C and at 99°C by the ISS confirm that no bacteria grow.

Why do black marks appear on the plastic of the filter?
The vegetable carbon in granular form contained in the filter may release a little fine powder, that is absolutely NOT harmful. This powder can sometimes stick to the walls of the plastic, making it darker. This does not compromise in any way the functionality or effectiveness of the cartridge.

Can I use the pitcher even without the anti-sediment system?
Without the anti-sediment system, the filtering system remains completely functional and effective. The anti-sediment system retains any residual sediment without any prejudice to the performance of the pitcher. 

How long does a filter last and how many liters can actually be filtered?
The filter has a lifespan of 2 months / 150 liters as indicated on the packet. At the end of its life it releases none of the retained substances, but become less efficient in its function of reducing and absorbing undesirable substances.

Do filters also reduce the presence of lime-scale?
LAICA offers drinking water filters which maintain the balance of Salts and others intended for the use of tea/coffee machines and kettles, which reduce the hardness and thus prevent the formation of lime-scale in the domestic appliances.

Can filtered water be consumed by anyone?
Yes, LAICA filtered water can be consumed by everyone. It is recommended, however, in the case of disease or special diets, to first consult your doctor.
