Water is one of the fundamental building blocks of life, and many of us probably aren't drinking enough of it.
The US National Academies of Sciences, Engineering and Medicine put the recommended daily intake of water at 3.7 liters for men and 2.7 liters for women.
However, if we are expected to drink up to 10 cups of anything a day, then it doesn't hurt to make sure it is free from contamination.
No matter where we live, the water from our taps is very seldom completely clean.
As well as things like, dirt, pesticides, and trace amounts of metal, the water we drink has often been treated with chemicals like Chlorine to combat these aforementioned substances.
This is why many people in the US and the rest of the world use water filters to remove debris and other toxic contaminants.
Filters allow us to feel safe in the knowledge that the water we are drinking is clean, safe and healthy.
Often filters are made for attaching to pitchers, but these require constant refills and once they are empty you will be stuck with regular tap water again.
Faucet filters on the other hand are easy to install on and allow you to get crystal clear water whenever you want straight from the tap.
So without further ado, let's look at some of the best faucet water filters currently on the market.

Best Faucet Water Filter Buying Guide
If you are concerned about the quality of water in your home, then a faucet filter system is a great choice for improving it.
However, not all of these models work in the same way, and some will be more effective than others depending on a variety of factors.
As such, we have included this buyer's guide to show you the most crucial elements any faucet water filter needs.
How Long Does Each Filter Cartridge Last?
The life expectancy of each filter cartridge varies greatly depending on where you live. Some areas have extremely hard water, while others have soft, fresher tap water.
In addition, there are many types of filters available, and they all use different methods to purify your water.
For example, some filters use activated carbon to remove impurities, while others use ion exchange resins to do so.
It's important to note that no matter what type of filter you buy, you will always need to replace the cartridge eventually.
As such, you will want to buy a product that makes this process straightforward and simple.
After all, a great filter system won't be worth much if the filter cartridge is nearly impossible to remove and replace.
Some units will even have helpful lights for indicating when you need to replace the filter.
If you suspect that your water contains a lot of pollutants, then you should buy a more heavy-duty filter that will last longer between replacements.
What Type Of Faucet Do You Have?
Not all faucets are built the same, and they can vary greatly in size and shape from household to household.
Most filters will only be able to fit onto modern taps with removable aerator tips.
Some kits will come with adapters for fitting onto different types of spout, which is great for households without standard faucets.
If you have a tap with a very unconventional spout shape, then you may struggle to find a filter system that will fit.
If this is the case, you may need to settle for a countertop or pitcher filter instead.
You will want any faucet filter that you buy to be completely watertight and durable enough to withstand daily use.
If your unit leaks, then it won't be very good at cleaning your water, and it will likely only succeed in creating a mess around your sink.
As such, you should look out for a product built from high quality materials that won't leak after a few weeks of continuous use.
What Do You Want To Filter Out?
Some filter systems will be better at removing specific contaminants than others.
Most units are capable of lowering the amount of bacteria, and chlorine in your tap water, but they can vary in their effectiveness when it comes to total dissolved solids (TDS).
For those with soft water that is already pretty fresh, this won't be an issue.
However, those with extremely hard, or contaminated water may want to invest in a more heavy-duty filter to guarantee they are removing dissolved solids as well as larger particulates and bacteria.
Options For Changing The Spray
A useful feature to look out for when it comes to faucet filters is the ability to switch back to regular tap water.
After all, you don't want to be wasting your cartridge on anything other than drinking water and food preparation.
The option to adjust the spray means you can switch back from filtered to unfiltered water for doing dishes or other chores where the water quality won't matter.
Frequently Asked Questions
How Do Faucet Water Filters Work?
Faucet water filters attach to the spout of your faucet and redirect the water from it into a specially designed cartridge.
This cartridge contains a substance like activated carbon for removing any impurities from your water supply.
The clean water is then let out through an opening at the bottom of the cartridge, so you can drink it.
How Can I Tell If My Filter Needs Replacing?
Some models will have LED lights for indicating when you need to replace the filter cartridge.
However, if your faucet filter doesn't have this option, there are other ways to tell when it's time for a replacement.
Slower flow rate, peculiar tastes in your water, or bad odors are all dead giveaways that your system isn't working the way it should.
If you notice any of these tell-tale signs, then you should buy a new filter cartridge as soon as possible.
What Are The Benefits To Alkaline Water?
Some faucet water filters are capable of raising the PH of your water to make it more alkaline.
According to some sources, alkaline water has a number of different benefits, including preventing some diseases and cancers, as well as preventing bone loss.
Other claims include alkaline water slowing down the aging process and helping to improve your focus.
It is worth noting that the veracity of these benefits is greatly disputed and a contentious topic among scientists.
As such, you should buy a filter for its ability to remove impurities from your water, and take it raising the PH of your water as a nice extra rather than a main selling point.
