Tools and Materials Required

You will first and foremost have to garner these supplies:


  • Wrench

  • Pliers
  • Pair of gloves
  • Protective attire e.g. aprons or overalls


Step-by-set Procedures

Now follow these steps to actualize the set up:

Step I: Find the right filter for your faucet

It all begins by finding the right filter for your faucet. In your search for the right filter, factor such issues as the compatibility between the two gadgets, the sheer sizes and dimensions, and the operational expertise that may be needed to bring the two of them to fruition.

Step II: Remove the aerator

Now proceed to remove the aerator from the faucet. This is to prep the faucet to be able to accommodate and attach to the filter. To remove this aerator, simply turn it in the anti-clockwise direction repeatedly and gently at the same time. Be careful that it sustains no damages in the process.

Step III: Connect the filter

At this stage, you should now connect the filter to the water faucet. Simply slot the filter in the space that is left out. Proceed now to tighten the two until such a time that the joints are firmly fixed together and do not stand a chance to detach or fall off.

Step IV: Attach the diverter valve to the faucet

Follow the above step by attaching the diverter valve to the faucet. The role of this attachment is to help regulate the flow and the volume of the water discharge. Be sure to fix it firmly and well to prevent it from leaving out the water to flow in too much quantity or amount.

How Countertop Water Filters Work

Knowing how the countertop water filters work is another great thing to do more so if all you want is to appreciate them and know how to fix any emergent errors. At this stage of our discussion, we shall peek into the inner working mechanisms of these water filters for you to familiarize yourself with.

Below are the steps and technologies involved in the working of the gadget:

Mechanical Filtration

For one is the mechanical filtration. In this sense, the filters push out the water through smaller pores. These pores measure somewhere between 0.1 – 0.3 microns. In the course of pushing out the water, the debris is left behind while the freshwater finds its way to the tanks or faucets.

Water Softening

Next is the water softening technique. Under this technique or scheme, the ion exchange mechanism is greatly employed to eliminate the hard minerals like the Magnesium and the Calcium from the water. In the course of this, the water output is softer and cleaner overall not to mention being free of toxins.

Activated Carbon Filtration

At some times, the water may contain dissolved organic contaminants like the volatile organic compounds, chlorine, disinfectants, herbicides, pesticides, and so on. You can never rely on your ordinary water filters to eliminate these compounds. The activated carbon filtration is the one that is chiefly used to eliminate them.


Alkalization is the breakdown of the acidic components of the water to make it safer and more neutral to the taste. The infrared rays are extensively used to ionize or neutralize the acidic components of the water to make it more alkaline. This also kills off germs to make the water safer and less of a hassle to you.

KDF Filtration

The KDF filtration is a technique that is largely used to eliminate the heavy metals from the water to make the same devoid of the toxins and safer to drink. This filtration mechanism eliminates the Hydrogen Sulfide, Chlorine, Lead, Mercury, and Iron from the water. In turn, it leaves behind safer and potable water for you to drink.

Drum Dispensing Systems

Filtering out the water is one thing. Having this water channeled to the precise place where the same is needed is yet another thing altogether. The drum dispensing system is the one you use to direct the flow of the water to the place where the same is or might be needed.

Filter Heads

Obviously, the filters get worn out with use. They have to be fastened and spruced to be able to keep discharging their roles regardless of the number of strains they may have already endured.
