The mains water supply in the UK is reassuringly well-regulated, to make sure it is fit for human consumption. Despite this, there are certain chemicals and minerals present even in tap water, and the volume will vary depending on which area of the country you live. For example, the south of the UK has high levels of limescale in the water.

Limescale is a chalky deposit of calcium and magnesium, and when there are high levels present in the water, it is known as ‘hard water’. Areas such as the north west have lower levels, known as ‘soft water.’ Limescale is not actively harmful to health, but it can build up on domestic appliances, causing them to work less efficiently.

More worryingly, the water supply may contain microplastics and toxic chemicals which some studies show are not yet being tested for in the UK. The water supply already contains legally approved chemicals such as chlorine, which acts as a disinfectant. This is unavoidable, but some people find it has an unpleasant taste.

For these reasons and more, many people choose to install a water filtration system. They provide that extra peace of mind that harmful toxics are being filtered out, safeguarding the health of their family. Residents of older properties which may have toxic lead piping are advised to filter their water, for example.

For those who live in hard water areas, the benefits are even greater. Limescale causes unsightly build ups on appliances such as kettles and taps, and even small amounts in a boiler can make it less efficient. Over time, inefficient appliances can add significantly to your annual household bills.

Hard water can also cause skin irritations and make hair look dull, so many people who live in these areas install a filter on their shower head. These are just a few of the many reasons to consider using home water purification systems.

Reverse Osmosis is a water treatment process that aims to remove all contaminants from the water molecules through a semipermeable membrane; during this process, any/ all contaminants are then all filtered and flushed away, only to leave clean, refreshing drinking water.

Health and looking healthy are the biggest form factors for water filtration, especially when the water you wash with is drying your skin or damaging your organs. If you have a look at the majority of the water that goes through our cities and homes are all contaminated one way or another; and almost every time it's high levels of chlorine, fluoride, lead etc.
