Now let’s know a bit more about the faucet water filters in the next section.

What is a Faucet Water Filter?

After hearing or reading about the faucet water filter, the first question that arises in our minds is: What exactly are these filters, and are they worth it?

The faucet water filter system removes contaminants from the drinking water. The faucet water filter directly attaches to a faucet in your kitchen. It instantly filters the water that comes out of the tap. Unlike pitcher filters, you can get as much clean water as you want in one go.

The best faucet water filters can remove more than 70 different contaminants. Such filtration can protect you and your family from waterborne diseases. In those areas where municipal water systems are quite outdated, this faucet water filter proves to be extremely useful.

A faucet water filter system is relatively inexpensive. It can save you from a cumbersome and expensive way of buying your water from a supermarket. A good quality faucet filter can filter the water for up to three months. Afterward, you can easily clean its cartridges or replace them for a reasonably low price.

Anyone can easily replace these filters every three months. Therefore, your family can enjoy an uninterruptible supply of clean and fresh drinking water.

Types of Faucet Water Filters

More and more homes are installing these faucet water filter systems. One of the primary reasons for their popularity is their lower price and easy maintenance. Moreover, they also deliver excellent quality of water. There are several manufacturers in the market, but all these faucet water filters work more or less similarly.

There are two main types of faucet water filters based on their size and output. It is also possible to control the time when you want filtered water. Because washing dishes don’t need filtered water, and it would be an unnecessary stress on the filter cartridges. 

Direct Flow-Thru Faucet Water Filter

These faucet water filters are highly portable and can attach to a faucet pretty quickly. Due to their small size, they are incredibly cheap. Usually, they come with different designs and build qualities. Therefore, it is necessary to choose the best faucet water filter based on your needs.

These filters are small and hence have a small surface area. They cannot filter large quantities of water that quickly. Moreover, they cannot remove too small impurities, which can only be removed by the side offset flow-thru faucet water filter.

Side Offset Flow-Thru Faucet Water Filter

These faucet water filters are a bit bigger than direct flow through filters. As their name indicates, you can easily set it up on a side near the faucet. Due to their bigger size, they can have more giant filters and a higher surface area. They last longer and can filter out even the tiniest impurities from the water. It is also easy to replace its cartridge filters. 

One of these filters’ advantages is that you can choose when to filter the water and not. Usually, there is a button on every side offset flow-thru filter to activate and deactivate the filtration process.

However, one disadvantage could be that they are not as portable as direct flow-thru faucet water filters. But, the quality of water it delivers and its lifetime overcomes any of its disadvantages.

How Does a Faucet Water Filter Works?

It is essential to know the difference between the faucet water filtration system and a reverse osmosis system. The faucet water filters can only filter water by using a three-step approach. On the other hand, reverse osmosis systems purify water by using reverse osmosis mechanisms. Therefore, one should not confuse filtered water with purified (distilled) water.

Usually, reverse osmosis systems help to purify filthy and contaminated water. But, the faucet water filter system aids in filtering the municipal or groundwater.

Generally, the design and shape of different faucet water filters can vary due to different manufactures. But, all these filter systems use a three-step filtration mechanism:

  • Step 1

A meshed and porous filter or a non-woven screen helps remove large sediments and particles in the first step. This step removes dirt, sand, debris, and rust.

  • Step 2

The second step uses activated carbon to remove impurities. Activated carbon is known to have a large surface area, and it can absorb impurities with the help of a process called adsorption. It can remove contaminants like chlorine. The activated carbon also contains silver or a similar chemical to kill bacteria and fungi.

The cartridge containing activated carbon clogs with the accumulation of these impurities. Therefore, replacing or cleaning the cartridges becomes necessary.

  • Step 3

This step is most crucial, as it removes those impurities that have severe health complications. It involves filters with microscopic pores. These micropores can capture all the chemical contaminants like heavy metals, calcium, magnesium, etc. It also helps in the removal of odors and unpleasant tastes from water.

Therefore, the water after this stage becomes healthy and refreshing for drinking.

What can a Faucet Water Filter Block?


Before you buy a faucet water filter, make sure you know what a faucet water filter can block and what it is not. All water filter models can quickly remove the chlorine from your water to improve the water’s taste.

Second of all, these filters are also responsible for removing maximum large contaminants such as dust, rust, sand, and debris. This will not just improve the taste but will also provide you healthy, clean water.

Also, an activated charcoal filter is extremely best to remove off volatile organic compounds from the water. It even removes those smaller segments that might have escaped the first screen. Furthermore, treated charcoal is helpful to remove some bacteria and harmful viruses.

10 Reasons to Buy a Faucet Water Filter

The reasons or benefits of buying a faucet water filter are synonymous with the benefits of healthy and filtered drinking water:

1. Inexpensive

Even the best faucet filters are cheap. They deliver quite a high benefit to cost ratio. They can spare you the cost of buying bottled water from the supermarket.

2. Easy and swift installation

First thing first, it is relatively easy to install these filters. They always come with a quick installation guide. The whole installation process might not take more than ten minutes.

3. Easy and Cheap Maintenance

The faucet water filter systems have very low running costs. A lot of times, it is relatively easy to clean their cartridges manually. Even the replacement cartridges are quite cheap and are readily available at any supermarket or an online store.

4. Healthy and quality water

The faucet water filter will undoubtedly enhance the quality of water. It doesn’t matter if you are using municipal water or groundwater; the filtration will remove almost all unhealthy and harmful contaminants. You will soon start observing improvement in your and your family’s health.

5. Rust and dirt-free water

Iron toxicity can be hazardous for you and your family. The faucet water filter effectively removes dirt, debris, and iron contaminants and gives you a refreshing experience.

6. Removal of bacteria and fungi

Different disorders like dysentery, cholera, and many others occur due to the contaminated water. The activated carbon cartridge inactivates bacteria and fungi, resultantly protecting you from such diseases.

7. Nitrates and Nitrites free water

Nitrates and Nitrites can cause blood disorders and brain damage. These contaminants can leak into your water supply from pesticides and fertilizers. Faucet water filters are efficient in removing such pollutants. 

8. Chlorine-free water

Municipal water management authorities use chlorine to clean the water supply. But, this chlorine can result in several health complications like vomiting, coma, and even cancers. The faucet water filters remove chlorine from the water and therefore saves you from these health issues.

9. Removal of Heavy metals

Heavy metals have a long history of causing cancer and kidney damage. These metals can leak out into household water supplies from the pipeline system and soil. The faucet filters can easily block these metals and hence sparing you from health complications.

10. Free of unpleasant smell and taste

No one likes to drink water that has a foul smell or unpleasant taste. The faucet water filters can block any nasty taste and smell, thereby giving you a whole new refreshing and healthy experience.

Best Faucet Water Filter Buying Guide

Selecting the best faucet water filter for your home can be a little tricky sometimes. There are several faucet water filter reviews available online. You might find yourself stranded due to different reviewers claiming different filters to be the best faucet water filters ever.

However, we will suggest you think about your needs and limitations. Also, look at various features of a faucet water filter system. In the end, try to decide on which filter you are going to buy for your home based on your preferences.

This guide will talk about some of the main guidelines for choosing the best faucet filter for your home. By reading these guidelines, you will be able to decide your future faucet water filter system by yourself.

Analyze your needs

Firstly, you should analyze what exactly do you need from your faucet water filter. In this regard, you can decide based on the present quality of your faucet water. If the water is too smelly, has a weird taste, feels chlorinated, has a higher iron content, feels polluted, etc.

Another deciding factor is the type of faucet you have in your kitchen. One faucet water filter might not fit all kinds of faucets. Therefore, search for a filter system that matches your kitchen’s faucet design. Apart from this, you can also think of the amount of filtered water you need every day because smaller filters will have less water filtration capacity in their lifetime. 

Portability

Portability can be a decisive factor for some people. There are different filters like direct flow-thru filters, which are highly portable. However, these filters have a few disadvantages. The lifetime and the filtration capacity of these filters are not as high as side offset flow-thru filters.

Moreover, as they are directly attached to the faucet’s end, they face more water pressure. That is why you have to change their cartridges more often than the side offset flow-thru water filters. By the way, if you live alone in your apartment, then a direct flow-thru filter can be the one for you.

Brand

There are several brands available in the market. You might feel difficulty in choosing a brand. If you feel stranded, you can seek help from your colleagues who use such filters at their homes. Moreover, we will suggest you go for a thorough review of any brand you might think is suitable for you. It would be best if you read not only the positive comments but also negative comments.

In the end, you can decide which brand is suitable and beneficial for you. Undoubtedly, the brands with a higher reputation and customer reviews are generally trustworthy.

Material and Build Quality

It would be best if you never compromise on the build quality of any product. In most cases, metallic faucet water filters have a better build quality and are less prone to leakage. Their parts are tightly packed, and hence they deliver a better quality of filtration.

The filters made of plastics are comparatively cheaper, but their lifetime is less than the metallic ones.
