Water, as the source of life, is a critical component of healthy living. How to drink and use water safely and healthily has become a trendy topic. With numerous water purification products on the market, the whole house water gains its fame for convenience and efficiency. In today’s article, we are going to talk about the benefits of whole house water filtration and also shortlist the five best whole house water filter systems.

What Is Whole House Water Filtration System

Whole house water purification is an "integrated" water filtration system that improves the drinking water and water environment of the whole house. It aims to purify the tap water in the whole house such as kitchens, bathrooms, balconies, living rooms, etc., to meet the higher health quality requirements of household water for drinking, eating, washing, bathing, and other aspects.
A complete whole house water purification system should include a pre-filter, a central water purifier, a central water softener, and additional end-water purification systems if needed. The whole house water filtration system treats water according to the different needs of household water.

Why Is the Whole House Water Filter System a Necessity?

If you use well water as the main source of water, then the answer is an absolute “YES.” Well water could contain a great amount of large to small impurities that is not ideal to use and drink directly. It is necessary to filter the well water before any consumption. If your house has access to city water, then you can utilize the whole house water filtration system to improve the overall water quality.
The widely-known water purifications are the end-use house water purification products, which can only provide direct drinking water for the kitchen, while the whole house water filtration system provides clean and safe water throughout the entire house.
With whole house water filters, the house water supply is divided based on the different water needs of the kitchen, bathroom, washing machine, and other areas of the home. It offers 360-degree protection for the whole house water supply.
According to relevant research data of the World Health Organization (WHO), the main ways and the approximate proportion of "harmful substances in water" absorbed by the body are 1/3 oral intake (drinking water, brushing teeth, food), 1/3 skin absorption (washing hands), Bathing), 1/3 respiratory tract inhalation (cleansing, bathing). WHO suggests that home use water and daily drinking water should follow the same standard!
Therefore, it is quite necessary to install a whole house water purification system to access safe water for both drinking and use.

As we have mentioned above, the whole house water filter system is composed of several independent water filters that can treat water for different uses.
