Explanation of how whole house water filters work and identifying the products that really work!

A whole house water purifier is a device that is capable of purifying and treating tap water throughout the home. It uses a range of different filters and treatment technologies that can remove impurities, contaminants and harmful substances from tap water to provide clean and safe water for drinking and use. When choosing a whole house water purifier, it is important to understand how it works as this can help us to identify the products that really work.

The working principle of a whole house water purifier can be categorised into three stages: pre-treatment, main treatment and post-treatment, each of which has different filtration and treatment steps.

Firstly, there is the pre-treatment stage. The pre-treatment stage removes large particles of impurities and contaminants from the water before the tap water enters the water purifier. A filter or mesh is usually used to filter out suspended matter, sediment, rust particles, etc. to prevent these particles from clogging other processor parts. This step protects the subsequent processors from working properly and extends their life.

Next is the main treatment stage. The main treatment stage is the most central and critical part of the whole house water purifier. This stage usually uses multi-stage filtration and treatment technologies to remove various pollutants and harmful substances from tap water. Some of the common filtration technologies include granular activated carbon filters, fibre membrane filters, ceramic filters, ultrafiltration membranes, reverse osmosis membranes and so on. Different filters have specific functions to remove different types of pollutants from water, such as bacteria, heavy metals, organic compounds, chlorine, pharmaceutical residues, etc. Some advanced whole-house water purifiers can also automatically adjust the filter's working mode and sequence according to the quality of tap water and water quality needs to ensure the water quality.

It is the post-treatment stage. After the main treatment stage, the water quality has been better improved, but traces of harmful substances or flavours may still be present. Therefore, the post-treatment stage usually employs further processing or improvement techniques to ensure that the water quality ultimately meets the standards. Common post-treatment technologies include ultraviolet sterilisation, ozone sterilisation, remineralisation and negative ion treatment. These technologies remove bacteria and viruses, adjust the pH of the water, improve flavour, and further improve the safety and quality of the water.

Identifying a truly effective whole house water purifier is not an easy task as numerous brands and types of products exist in the market. There are several factors to consider when choosing a whole house water purifier. The first is the product's filtration effectiveness and treatment capacity. A quality whole house water purifier should be able to remove a wide range of pollutants and harmful substances from tap water in order to provide high quality water. Next is the durability and reliability of the product. A good whole house water purifier should have a long lifespan and warranty and be able to maintain good treatment results over a long period of time. The price and maintenance cost of the product also need to be considered, as well as the quality and reliability of the after-sales service.

In summary, whole house water purifiers use multi-stage filtration and treatment technology to provide clean and safe water for drinking and use by removing particles, pollutants and harmful substances from the water. Choosing a truly effective product requires a combination of factors such as filtration effectiveness, durability, maintenance costs, and after-sales service. It is only by knowing and understanding how whole house water filters work that we can make an informed choice to ensure the quality and safety of water in our homes.
