What is Faucet Water Filter?

Faucet water filter is a device that is designed to filter the water that gets into our home, at the stage of the tap from which it is to get out. This is one of the most popular and common forms of water filtration at home. This is because the cost of purchasing such a filtering device is much lower than other types of water filtering devices.

You also do not have to deal with a troublesome installation because it only takes a few minutes for the device to be mounted to the tapIt is also easy to replace the filters, which must be replaced every few months depending on the device In faucet water filtration systems, the filtration process usually takes place in three stages.

During filtration stages, over 90% of contaminants such as rust, sand, dirt, chlorine, lead, mercury, nitrites, nitrates are removed and the taste and smell of water are improved.
All these aspects make up the huge popularity of this type of devices and, consequently, their large variety on the market. In the text below we have included all the necessary issues to be considered when choosing the best device for you.

How Tap Faucet Water Filters Work?

Most Faucet Water Filters models have a filtration system that works on a very similar principle. Many of them have a cassette filter, which contains a certain number of elements that work together. The main differences between the models are the quality of the materials from which they were made, the size and durability of the filter.

Below is a brief description of each of the three stages of water filtration that occur in most faucet water filters.

Stage one – mainly large particles such as rust, dirt, or sand are retained in this stage.
This happens thanks to the non-woven screen wrapped around the cartridge.

Stage two – in the next stage, partially filtered water goes to activated carbon block in which the phenomenon called adsorption occurs. It consists in the fact that the coal which is in the filter has a porous surface filled with many nooks in which impurities from the water that flows through it stop. It should be remembered that with prolonged use of the filter, these nooks and crannies will fill up, which may reduce the efficiency of the filter. Therefore, remember to change the filter regularly according to the manufacturer’s instructions. In some models, it happens that special substances are added to carbon filters that are designed to improve filtration. An example of such a material may be silver that kills fungi and bacteria.

Stage three – in the last stage, there are processes that are aimed at reducing the level of chemical pollution because the filters from previous stages deal mainly with solid pollution. Here, impurities such as mercury and lead are removed from the water. The filter also improves the taste and smell of water.

The Benefits of Faucet Water Filter

There are many benefits to using the faucet water filter, here are some of them:


Clean water – this is one of the most important advantages of using the faucet water filter.
Even though this device does not purify water as effectively as the reverse osmosis water filtration system, it can retain over 90% of chlorine and impurities such as rust, benzene, or lead.
Thanks to this, you and your family can be sure that you consume water free of most pollution.

Food and drink – an important benefit of faucet water filter is the possibility to use pure filtered water for food and drinks such as coffee or tea. This will favorably affect the taste and smell of the meals we eat. See for yourself that the same coffee or tea can taste entirely different than before.

Animals – often thinking about how we can improve our lives, sometimes we forget about our beloved pets. A dog, cat, guinea pig, or rabbit-like all other animals must consume water. Have you ever wondered how polluted water can affect your pet? Do you know that water with a lot of stone can settle on your kidneys? With the faucet water filter, you can improve the health of your pet.

Be more ECO – recently, many of us are trying to improve the purity of our planet. Using the faucet water filter will reduce your consumption of bottled water and, thus, the disposal of plastic and the need to process it. From now on, you can influence the improvement of living conditions on our planet.

Easy installation and replacement of filters – many of us are frightened by the vision of the long-term installation of the water filtration system and the fight against water and sewage lines. On the opposite is the faucet water filter, which can be mounted on our tap in a few minutes. The same applies to replace filters with new ones; it is so simple that you can do it with your eyes closed.

Faucet Water Filter Installation Process

Faucet water filters are designed in such a way that the installation proceeds quickly and efficiently.
Regardless of which company we buy our filter, installation in most cases is the same. Before you get to work, prepare an adjustable wrench and some Teflon tape. Some manufacturers add the necessary components to the sets, but it’s worth having everything ready.
The following is a brief description of the steps needed to install a faucet water filter.


1. You must first remove the faucet’s aerator. It should be unscrewed with your hand, but if this is impossible, you must use the adjustable wrench.

2. Put the aerator on top of the inserts that come in the water filter’s box.

3. Screw on the new aerator with the tap insert and Mount the faucet water filter

4. Turn on the water and let it running for at least 5-10 minutes before you want to drink it.
Thanks to this, the filter will be activated.

5. Make sure there are no leaks. However, if any leaks occur, use a Teflon tape.

Faucet Water Filter Replacement

Filter replacement on most models is done in the same way and does not take more than a few minutes. The frequency of their exchange depends on what model we bought. If our filter has a change sensor, you have to adapt to it. If your faucet water filter does not have a filter replacement indicator, the best solution is to enter in our phone or calendar when we installed it.

The question arises: how much should our faucet water filter be replaced? On average, man consumes 2 gallons of drinking water per day. Depending on how many people live in the house, the average is between 2 and 8 gallons per day. This means that a family of two will replace the 200-gallon filter approximately one and a half months. These data are averaged. It all depends on our private water consumption.


Thanks to the developed faucet technology, water filters can stop most of the pollution in the water. Until recently, this quality of filtered water was only possible with the use of large and expensive filter systems.

An argument that can not be overlooked when buying a water filter is its price. With a small financial outlay, we can improve the quality of water we eat, improve the quality of prepared dishes and much more.

We hope that after reading the best faucet water filters review, you will be able to choose for yourself the most convenient model from which you will be delighted.
