Water is a source of life, but its quality directly affects our health and well-being. Even though tap water goes through purification processes, it may still contain contaminants that we want to remove before consumption. Water filtration is therefore becoming not only a matter of comfort, but also a health necessity. In this article, we will discuss how to choose the right filter for your tap water, dividing filtration methods into point-of-use (POU) and centralized (POE) systems.
Basic information about water filtration
Water contaminants can be divided into chemical (e.g. chlorine, pesticides), biological (bacteria, viruses) and mechanical (rust, sand). To remove them, various filtration technologies are used, including mechanical filtration, adsorption filtration (e.g. with activated carbon), ion exchange filtration and reverse osmosis.
Point filtration (POU)
Jug filters
These are the simplest and most accessible filtration systems. It works by passing water through an ion exchanger and activated carbon, which reduces chlorine, some heavy metals and improves the taste of the water. Their advantage is low price and simplicity of use, but they require regular replacement of cartridges.
Tap filters
Mounted directly on the tap, they offer similar filtration to jugs. They are relatively easy to install, but may require filter replacement more frequently depending on water quality.
Under sink filtration systems
In this case, we are dealing with advanced technologies such as reverse osmosis, which is able to remove most contaminants, including bacteria and viruses. While effective, they require plumbing and take up more space.
Central filtration (POE)
Mechanical filters
Installed on the main water pipe, they filter mechanical impurities before distributing water throughout the house. They are the first line of defense in your home filtration system.
Water softeners
Mainly used to reduce water hardness, which is crucial for protecting household appliances and installations against limescale.
Carbon filters
Used to remove chlorine, organic contaminants and improve the taste and smell of water. They can be part of a larger filtration system.
How to choose the right filtration system?
Choosing the right filtration system depends on your individual needs, water quality in a given location and budget. Water analysis should be performed to determine the main contaminants to be removed. Then it is worth comparing the investment and operating costs of individual filtration systems and considering the available space and ease of operation.
Choosing a tap water filtration system is not an easy decision, but with the right knowledge, you can make a choice that will provide clean and healthy water. Regular maintenance and replacement of filters is key to maintaining the effectiveness of the filtration system and protecting the health of users.
