Filtration of drinking water
Water is an essential product for humans to survive. In addition to drinking a glass of water directly from the tap, we also use water in connection with e.g. cooking – where the water also comes into contact with the food we prepare. It is therefore important that the water is completely free of unnecessary particles that do not necessarily belong in our drinking water.

Water in the body - How much water should you drink daily?
Our body consists of approx. 60% water – the water content must also be maintained and therefore it is important for us humans to consume a given amount of drinking water on a daily basis.
How many liters of water should you drink? It's a relatively simple question, but the answer is not necessarily that simple. Most experts in the field agree that you should consume a minimum of 1 ½ - 2 liters daily, while others say that you are not harmed by 3-4 liters. The recommendations also depend on your activity level – the more active you are, the more water you should drink to maintain the water balance in the body. Water intake also depends on body weight. If you weigh 50 kg, you don't necessarily need to drink as much water as someone who weighs 80 kg.
Bacteria and other substances in drinking water
We hear more and more often in the media that there are bacteria and other substances in our drinking water. Some measurements are much higher than permitted and here residents in the affected areas are asked to boil their drinking water before consuming it. We expect the drinking water that comes out of the tap at home to be completely purified and free of, among other things, bacteria – which is often the case. When things do go wrong, it's nice to have an installation that can remedy these problems, so that you don't feel it when they finally occur.
Filter-Online has several products that are approved for drinking water filtration and thus the task is adult when it comes to filtering in your home, caravan or holiday home.
These can be drinking bottles that are easy to take with you when you are on a trip, reverse osmosis to place under the sink to clean the water of bacteria or filter jugs with replaceable filters, which absorb e.g. iron lead, bad smell and not least softens the water. Many of our customers take water from the tap and run it through a filter jug to soften the water before pouring it into their coffee machine - that way you have an affordable solution to softening water and that way you reduce the amount of lime that comes through the coffee machine.

At the same time, the sets have a cartridge (KH) that softens the water and thus reduces limescale.
