The terms water filter (or filtration) and purifier (or purification) are often used interchangeably. Whilst they have certain similarities, they are not entirely the same. A water filter is designed to remove unwanted substances, including toxins, chemicals, and sediments. The main goal here is to get rid of impurities and living organisms. Using a filtration system will remove odour and improve the taste of water.
On the other hand, a water purifier removes up to 95% of all contaminants. The main focus is to purify water, which improves its overall safety.
