Blood plasma consists of approximately 90% water, while our entire body contains about 60-70% water. This fact highlights how vital it is that the water reaching us is clean and safe, free from microbes, microorganisms, and harmful substances. Clean water means safety and health in our lives and daily routines. Although tap water in most areas is considered suitable for consumption, it often contains substances that affect its taste, odor, or even its overall quality. For this reason, more and more people are choosing to install a water filter in their homes or workplaces. But what does a water filter actually remove?<\/p>\n\n\n\n
Chlorine is used in water supply networks as the final disinfection stage, aiming to eliminate pathogenic microorganisms that can harm our health. Nevertheless, its presence in water often creates an unpleasant taste and odor, while for some, it may even cause stomach discomfort, making water consumption difficult in certain cases. Using a water filter that contains activated carbon can significantly reduce chlorine and its byproducts. Naturally, the quality of the carbon, as well as the materials and manufacturing methods used, play a critical role in the final result.<\/p>\n\n\n\n
There are instances where water can be contaminated by heavy or toxic metals, either due to the geological composition of the subsoil, aging piping systems, or environmental pollution. Specially treated activated carbon filters, carbon filters combined with KDF (Kinetic Degradation Fluxion) media, ion-exchange resins, Hollow Fiber (HF) ultrafiltration membrane systems, and Reverse Osmosis (RO) systems can significantly reduce or even eliminate the presence of these metals.<\/p>\n\n\n\n
The appearance of microorganisms in water is typically due to under-chlorination or poor infrastructure within the water supply network, leading to leaks and contamination. Reducing microorganisms (such as bacteria, cysts, etc.) in drinking water depends on the filtration technology used. If the contamination level is high, ultraviolet (UV) radiation systems or microfiltration membranes can eliminate these threats even more effectively.<\/p>\n\n\n\n
Sediments and suspended particles can originate from various sources, such as sand, rust, mud, and more. While a large portion of these is captured during the water network's treatment stages, factors like aging infrastructure, contamination, poor maintenance, or pipe bursts can lead to their presence in our tap water. Water filters act as a barrier that blocks these substances, significantly improving the water's clarity and purity. Ceramic filters are particularly effective, as they can be cleaned during use, maintaining high performance throughout their lifespan.<\/p>\n\n\n\n
In some regions, water may contain traces of pesticides and\/or organic compounds. Many modern filtration systems are designed to significantly reduce these substances. A high-quality activated carbon filter with specific micropores can effectively adsorb these compounds to a great extent, provided it is used within its recommended lifespan.<\/p>\n\n\n\n
One of the most immediate benefits of using a water filter is the significant improvement in the water\u2019s taste and odor. Activated carbon, especially in block form, possesses a high adsorption capacity, enabling it to trap substances that cause unpleasant smells or alter the water's flavor. The result is clean, crystal-clear water that is free from odors and highly refreshing to drink.<\/p>\n\n\n\n
Water scale consists of dissolved inorganic ions, primarily originating from rocks and the subsoil. The most common are calcium and magnesium salts, and to a lesser extent, sodium. Up to a certain level, these minerals are not harmful to health; however, they are destructive to household appliances. Effective breakdown or removal of scale is achieved through ion-exchange resins, reverse osmosis systems, and polyphosphate crystals (often referred to as siliphos or quartz beads), which inhibit scale buildup.<\/p>\n\n\n\n
Nitrates are dissolved compounds in water that originate from fertilizers, natural soil processes, manure, and wastewater (e.g., septic tank leaks). Depending on their source and concentration, they can be a significant indicator of water contamination; above certain levels, they can pose very serious health risks. For their effective removal, we utilize ion-exchange resin filters or reverse osmosis systems.<\/p>\n\n\n\n
The use of a suitable water filter can significantly contribute to improving the quality of the water we consume daily. Depending on the technology used, filters can reduce substances such as chlorine, heavy metals, sediments, pesticides, and other undesirable compounds, while simultaneously improving the water's taste and odor. Selecting the right filter and ensuring the regular replacement of its cartridges guarantee clean and safe water for the entire family.\nExplore our range of Aquarius filters!<\/p>\n\n\n\n

Filter replacement depends on the type of filter and your water consumption, but it is typically required every 6 to 12 months.<\/p>\n\n\n\n
Not all filters do. Complete scale removal is primarily achieved through reverse osmosis systems or ion-exchange resins.<\/p>","protected":false},"excerpt":{"rendered":"
