How Does A Faucet Water Filter Work?

Faucet water filters use a cartridge filter to remove contaminants from the water. Let’s look at the working of this gadget.

  • Sediment/dirt removal: The first step in the filtration process is to remove sediment, dirt, and rust that has made its way into the water. This process is done with the help of the non-woven screen surrounding the cartridge, which can block small and large particles.
  • Removal of contaminants: Once the water is free of debris or dirt, it passes through the active carbon block with a porous surface. Here, the water contaminants are blocked or trapped using an adsorption process. Further, the filtration process minimizes the contamination level of chlorine and heavy chemicals such as lead, mercury, and arsenic.

How To Install A Tap Water Filter?

A tap water filter is a compact and easy-to-use device that can be mounted onto your kitchen faucet with ease. Here are a few steps that you can follow to install a water filter:

  • Completely shut off the water supply by closing the valves under the sink.
  • Remove the faucet aerator. If it’s tightly closed, you could use a wrench to loosen it.
  • Now lay out all the parts that came in the package of your water filter.
  • Most filters come with more than one adapter and washer. So, select the adaptor that fits your faucet.
  • Attach the adapter and washer on the faucet.
  • Fit the filter (with the cartridge inside) to the faucet and tighten it well.
  • Open the tap and turn the knob (if it has one) to select the filtered water option.
  • Test to see if the water flow is steady and smooth, and there are no leaks.
  • Allow the water to run for at least 10 minutes before you use it for drinking.

How To Clean A Faucet Filter?

The only cleaning or maintenance that a water filter requires is replacing the cartridge once it’s dirty. This varies based on the capacity of the filter element. Some filters need to be replaced once a month, while others last for 6 months. All you need to do is unscrew the filter housing, remove the old filter, and put in a new one.

How To Choose The Right Faucet Water Filter?

  • Filter capacity: The capacity of a filter is of utmost importance. A basic faucet water filter will have a minimum capacity of 100 gallons and can go upto 2000 gallons. The capacity you require depends on the level of impurities in the water and how much you use.
  • Size: Most water filters are around the same size, or some may be slightly larger than the others. Choose a size based on the size of your kitchen sink.
  • Material: Almost all faucet water filters are made of durable stainless steel. But you will find a few plastic filters as well. If you are looking for something long-lasting, opt for a metal one.
  • Ease of installation: The fact is that most of them are easy to install and don’t require any extra tools.
  • Additional features: A flow selector could be an essential factor for some as it lets you switch between filtered and unfiltered water by just turning the knob. Other must-have features that you should look out for are whether it has a 360° swivel design or a light sensor that indicates when your cartridge needs to be replaced.
