Summary
We decided to create this page for faucet water filters because nowadays, they offer one of the best means of reducing and removing contaminants from your household or office water supply. Not only can they filter impressive amounts, but they also don’t produce wastewater like other types of filtration, offering a financial saving and benefiting the environment.
How they work
Let’s start by pointing out that it is likely the water source connected to your home or office isn’t an untreated or contaminated source. If it is, then you need a water purifying system and so you must ensure you don’t get the two systems confused.
However, let’s get back to faucet water filters – the majority use a cartridge of various components to improve the quality of water by up to 20% and whilst the components may differ between brands and models, the vast majority work in the following way:
Removal of sediment
The first step of the process is often a screen or wrap that prevents pieces of sediment, both large and small from getting through the filter. When we talk about sediment, we mean things like rust, dirt, sand or any other debris of that nature.
Activated Carbon
Once the initial filtering of sediment has been performed, the activated carbon filter within the cartridge gets involved. This is designed specifically to trap water into the porous surface of the activated carbon, known scientifically as adsorption. The majority of filters in bottled water, coolers and faucet filters utilise activated carbon and it is a fantastic resource. The only downside is that these will begin to lose their effectiveness over time and need to be replaced, but this is often an inexpensive and easy issue to resolve.
Removal of chemicals
The third step in the filtration process is the removal of certain chemicals that the activated carbon cannot, such as lead, mercury and nitrates. An added feature of this part of the process is that it also filters any potential odours and bad tastes, not having any health benefits but making the taste far nicer. You will often find the water flow is slower even when using the best faucet water filters because of the filtration process, but not to an extent that should cause problems.
The Benefits of Faucet Water Filters
There are many benefits to installing the best faucet water filters at your home or office and we have listed some of the key ones below:
Health
The number one reason for choosing a filter is that it will improve the quality of the water, meaning you and your family will use healthier water. This is because it will remove chlorine that is often found in water due to the industrial usage of it, any microorganisms found in water that can potentially harm people, such as Giardia and finally, it will block out nitrates and nitrites, frequently used in pesticides.
As an added extra, they will often filter out metals and rust that can be found in water, leaving you with even healthier, cleaner water at no extra cost to you.
Easy to install
People are often put off by choosing a faucet filter or purifier system because of the complex nature of the installation, or simply they are uncertain about how it’s done. With a faucet water filter, those concerns can disappear because they are incredibly easy to install, even for those with no experience. We’ve found that the majority of these filters can be installed in as little as 5 minutes.
For those that still struggle, the majority now offer online guides and tutorials, so you won’t be stuck at home frustrated. Furthermore, the filter change process, once they are installed, is generally easy to do and relatively inexpensive, with some even having a filter change sensor to assist you.
Improved smell and taste
As highlighted above in our section on how these filters work, a faucet water filter will help remove anything that has the potential to alter the smell or taste of your water supply. There is nothing worse than using water from a kitchen faucet in cooking or drink water that smells or tastes bad and so this is a massive benefit for all households.
Environmental impact
The environmental benefits of the best faucet water filters fall under two categories. Firstly, these do not waste water in the way that other filters will do, as it will only filter what you need and they also don’t need electricity to run, reducing the carbon footprint of the filter and your property.
Secondly, they reduce the amount of plastic produced and subsequently deposited back into the environment as you will no longer need to buy single-use plastic bottled water and they will not leak plastic back into the environment.
