How Does a Tap Faucet Water Filter Work?

Before discussing the way faucet filters work, it is necessary to get more information about them. Faucet water filters clean water and does not purify it. While many people think these two things are the same, they are actually different from each other.

To clear things up, water filters provide filtered water. On the other hand, reverse osmosis systems offer pure water. There is a significant difference between the two. The following shows an overview of this difference.

A water purifier is not used on treated water. It can be used on well water or contaminated water. These systems, such as reverse osmosis systems, can take out 99 percent of any contaminants in water. The term water purifying system can be used on systems that can remove a minimum of 95 percent of contaminants.

Water filters should not be used on water sources that are highly untreated or contaminated since they are not designed for it. When water filters are used as a filter system for faucet water, it enhances water quality by 20 percent. Due to this, it can enhance water and make it healthier before it was filtered. But, it does not automatically mean the water is beneficial for you. Highly contaminated water will still be dangerous even if you use a water filter.

So, how do these systems work?

Faucet water filters normally use a cartridge filter. This cartridge features different components that are used together in filtering contaminants in water. Even as each model is unique basing on its manufacturer, many of these water filters have similar components. They also work the same way.

  • Taking out sediments – the filtration process starts with removing sediments. This is normally done using non-woven screens that are wrapped around the filter cartridge. The screen is designed to block small and large particles, including dirt, sand, debris, and rust.
  • Blocking using activated carbon – with most of the sediment removed, the activated carbon will start its work. The porous surface of activated carbon has a lot of nooks and crannies. These nooks and crannies trap contaminants in water hen it passes through a process known as absorption. But, the activated carbon will become inefficient when its porous surface is filled with contaminants. Due to this, it is important to always use filters that are clean. These days, filter cartridges feature treated activated carbon. Due to this, the carbon has another substance giving it some unique features. There are instances when they add silver to take out bacteria or fungi that will get through the activated carbon filter. Chemicals may also be used with the same purpose.
  • Removing chemicals – the next stage in the filtration process is reducing the level of chemical contamination. While an activated carbon filter can take out typical contaminants, such as chlorine, these filters cannot remove chemicals, such as magnesium, calcium, and heavy metals. Due to this, many manufacturers include another filter to remove these contaminants. These contaminants include mercury, lead, nitrates, and nitrites. In addition, these filters also remove bad taste and odors. The period of time water remains in contact with these filter cartridges determine the number of contaminants they remove. For instance, the longer water is in contact with activated carbon filters, the more contaminants it will remove through its porous surface. Due to this, a good number of faucet water filters often offer a slow flow of water.
