A water purifier eliminates contaminants either by using a physical barrier, a chemical process or a biological process. Here’s a water purifier buying guide that explains active water filtration systems. Simply put, this system passes water through an active material that removes impurities chemically. In this article, we have listed different types of active filtration systems and their pros and cons. These tips will help you choose the right water filtration system for your home.
1) Fibre Filter
A fibre filter is made of rayon, cellulose or other similar microfibres, which are spun into a perforated mesh. Water is passed through these fibres that are wrapped tightly around the filters. For the best and most efficient purification results, select a fibre filter that has a micron rating lower than 1.
In this system, residue, muddiness and small organic particles that cause bad odour and taste are removed. However, dissolvable impurities such as lead, chlorine and mercury are not removed by this filter.
2) Solid Block Activated Filter/Charcoal Filter
The carbon in these filters are specially treated, compressed and bonded. This allows the filter to absorb contaminants at a high level. The unique treatment allows it to filter contaminants more effectively.
Distillation is the water purification process in which pure steam from boiling water is captured and condensed into liquid form. A vapour trap, carbon filter or other parts in the distiller filter remove all contaminants from the water. The nature of the filtration process is such that even extremely poor-quality water can be filtered and safely used for drinking.
4) Ultraviolet (UV)
In a UV-based purifier, UV rays destroy microbes. Water is exposed to the UV rays that penetrate the cells of the bacteria and destroy their ability to reproduce. All the bacteria, virus and microorganisms are removed.
