What does a water filter do?

Water filtration explained

A water filter system is designed to remove impurities such as chlorine, pesticides, and microplastics from your household water supply. These contaminants don’t just affect the taste of your drinking water – they can impact your health, your cooking, and even your plumbing. 

By trapping and removing these contaminants, a home filtration system gives you cleaner, clearer water, straight from the kitchen tap. 

Filtration process

How do water filters work?

Different filtration systems work in different ways, but the core process is much the same: mains water passes through one or more specialised filter materials that trap or absorb unwanted particles. 

Each Kinetico water filter is engineered to target specific impurities depending on your needs. We use two main filtration methods – carbon filtration and reverse osmosis – which we’ve explained in greater detail below. 

Carbon filtration

Carbon water filtration uses activated carbon, a highly porous material, to attract and remove contaminants. This process works by adsorption, where contaminants are trapped within the pores of the carbon and then flushed out. 

Activated carbon filters are used in our Premier Filters and are a great choice for fixing taste and odour issues in your drinking water, as well as for removing chlorine and organic contaminants. 

Reverse osmosis

Reverse osmosis is a water filtration method in which pressure is used to force water through a semi-permeable membrane, separating water molecules from impurities. This is highly effective at removing a wide range of contaminants – including nitrates, heavy metals, fluoride, and microplastics – making it one of the most thorough filtrations options available.

Reverse osmosis filtration can be found in our K5 range and Premier RO, and are ideal for households looking for premium water quality with maximum purification.

Filter taps

Why do some home water filters use a separate tap?

Some water filtration systems are designed to work with a dedicated tap for filtered water. This helps preserve the life of the filter by ensuring it’s only used where purified water is needed – typically for drinking, cooking, or making hot drinks.

Filtered taps are available as standalone 1-way options or as part of 3- or 4-way taps that also provide hot, cold, and even softened water.
