In counter or counter-top units that process the water at the site of use, e.g. in the kitchen for drinking, cooking, preparing beverages, etc., and only filter the water at exactly that point.
These systems are the least expensive filter systems for home Water treatment. Water filter experts have noted that under-or counter-top units are not the best choice for optimum pollutant removal, because they affect color, taste and smell of water, but are less effective in the removal of chemicals, bacteria, fungi and viruses.
Frequent Filter Changes, wasted space, inefficient removal of impurities and long-term lack of reliability of such systems for the consumer make it less attractive than Water treatment systems for the whole house, especially if you want a permanent solution that operates transparently. Most under-counter and counter-top units are reverse osmosis systems.
Whole-house water systems, as the name suggests, are designed for the house as a whole. These systems are attached to the main water flow at the entry point of the water in your apartment / house / office building and thus treat all the water that comes in. The incoming water flows through several filter layers of ultrafine particles to filter bacteria, molds and chemicals from the water. In general use such water filter activated carbon filter, possibly in conjunction with another Filter Technology.
A whole house water filtration system provides a home with an unlimited amount of pure water and effectively removes all currently known water contamination and pollutants. Every faucet, whether inside or outside, then produces pure and pH neutral water.
These filter systems require no backwash process are very inexpensive to maintain (filter change usually only once per year) and are also suitable for the filtering of well water. They also reduce the corrosion of pipelines, which reduces the staining of fittings (and laundry). Even companies (such as restaurants and cafes) and factories can use such a Water System their water clean.
