In our country, everyone has been taught since childhood that you should NOT drink untreated tap water. They say it's bad for you, it's full of chlorine, etc. That's why we boil and filter, filter and boil. In fact, even without lab tests it is easy to understand that agua del grifo is not of good quality.

Chlorine smell, scale and dirt in the kettle, rust stains in the pipes. It is frightening to think that drinking this type of water can lead to the appearance of "limescale" and "rusty runs" in our organism. Therefore, for many people there is no doubt that filtering tap water before drinking it is not only necessary, but vital.

What is in tap water that needs to be filtered?

Excess of chlorine compounds.

Chlorine is a well-known disinfectant in tap water. It fights germs and bacteria that are dangerous to humans, but it can also be a hazard. The guideline is that the chlorine content should not exceed 0.5 milligrams per liter. Even the simplest water filter will help you deal with excess chlorine in tap water.

Many people think that chlorine will disappear from water once it comes to a boil. This is not the case. You need to boil the water for at least 5 minutes to make the chlorine disappear. And the best option is to use a water filter before boiling.

Excess salts, iron and other minerals, resulting in hard water.

Hard water causes appliances - washing machines, dishwashers, water heaters, etc. - to malfunction. It is also harmful to our body: the extra iron and salts in the water cause damage to our body and other organs.

You can read more about water hardness and how to soften it here. Hard water needs to be softened, for example, water filters with softeners do an excellent job.

The likelihood of tap water mixing with sewage.

Since sewer and water pipes are laid side by side, and most of them are well past their retirement age, there is a chance that the pipes will burst and mix the water flowing through them into our homes with the water coming out of them.

So why should we filter our tap water?

To be healthy. So that our body does not accumulate unnecessary salts and other elements that interfere with the functioning of the organism. So that the devices designed to make life easier for us work for a long time and do not break down due to poor water quality.

And now the main question: what should water be filtered with and which water filters to use from the tap?

There are many water filters for different needs. For example, to solve problems with drinking water in the kitchen, the installation of a water filter with a tap at the kitchen sink will help you effortlessly perform universal purification of impurities (rust, silt, sand, etc.), as well as dissolved impurities, such as free chlorine, organochlorine compounds, pesticides, petroleum products, heavy metals.

If you want to use clean water not only for drinking, but also for bathing or showering, we recommend that you install a 15-stage shower filter. It is indispensable for people with sensitive skin, families with children and pets.

Thanks to the ion exchange resin, the filter can also easily cope with hard water. This water filter is enough for a small family, the main thing is to change the cartridge in time.

For a large family or a coffee shop, a reverse osmosis filter would be the best choice.
