These days, more and more people are aware of the risks that they expose themselves by drinking unfiltered water. Although the local authorities explain that tap water is safe to drink, there are certain water contaminants that can cause serious health problems, which is why people started to opt for water filters. If you are considering such a device, we advise you to read some whole house water filtration systems reviews or under sink water filter reviews. Still, how does the filtration process work? The filtration process is rarely approached in reviews, yet it too can be very important. Here is some valuable information that will help you learn more about water filter systems.

The slow sand filtration

The slow sand filtration process involves a stage where water passes through a special, granular bed of sand at a low speed. The special media that water goes through catches impurities and chemicals like sediment, silt, bacteria and other solid particles in order to provide healthy water, and to eliminate the risk of ingesting dangerous contaminants. The slow sand filters incorporate divided layers of sand, and they are used for treating municipal water. Furthermore, the slow sand filtration represents the oldest type of filtration, and it can’t remove the same number of contaminants that modern systems eliminate.

Modern filtration systems

Modern water filters use a solid, compressed carbon as the main component of the filter. This solid block form stops the passage of unwanted impurities, eliminating a wide range of contaminants from the water, including chlorine, lead, mercury, pesticides, herbicides and VOCs. Moreover, water filters that use innovative technologies integrate other medias besides the carbon media, and they provide healthy water through both chemical and physical procedures. While the physical process implies preventing contaminants from passing through the filter, the chemical process applies an adsorption method, using the carbon’s atomic charge to force unwanted impurities to attach to the media. The water then flows through the media, cleansed of chemicals and dangerous materials, which allows people to prepare fresh, great-tasting beverages and foods. However, adding extra medias to a standard filter can result in a greater water improvement, as the filter performance will be more effective. So, those who are thinking about purchasing such a product, should pay attention to this detail.

What to consider before buying a water filter?

A very important aspect that must be considered before purchasing a water filter is that not all filtration systems were designed to eliminate all types of pollutants. A water filter can remove a specified type of contaminants, so you must buy a unit that can suit your needs. Therefore, you have to analyze your local water reports, and only after finding out what type of impurities your tap water has, you can decide on a certain water filter to increase the quality of your water. Moreover, products which use the same filtration may not have the same efficiency. If you are considering a big investment such as a whole house water filter, it is of utmost importance to first read some whole house water filtration systems reviews in order to find the unit which would bring you the most benefits.
