Buying guide


The materials present in a faucet water filter tend not to differ too much between makes and models, and they are usually comprised of:

Ion-exchange resin – The resin exchanges one type of ion for another, so that your water is as clean as it needs to be. When lead and other harmful ions are present in the water, the resin swaps these ions for healthier ones such as potassium and sodium.

Activated carbon – Also known as ‘Charcoal’, activated carbon is a porous material that is made up of nut shells, coconut husks, and wood. Carbon has the ability to absorb a wide range of odors, organic compounds, and colors, so that your water tastes and smells great.

Minerals – Some faucet water filters come with a layer or two of minerals that work to give the water a cleaner and fresher taste.

Electric or not

Electronic water filters can help you to determine how much life is left in the filter itself, but water filters that don’t have electronic capabilities can work just as well.

If you want to know how much more water can be filtered, feel free to purchase an electronic faucet water filter, but be prepared to pay a little bit more for it.

If you are a fan of gadgets and gizmos, you may wish to purchase a faucet water filter that has been Bluetooth enabled. This feature allows you to monitor how much life is left in the filter, via your cell phone. To do this you may have to download an app, and keep your Bluetooth on at all times, but that shouldn’t be an issue. Electronic filters can be very handy, however, if you’re happy to use a regular filter, you are likely to end up paying a little less for it.


You may have noticed that there are a lot of different models available, and it’s quite likely that you’ve found it hard to choose the right model for you. Some models differ in terms of color, others may have to be installed vertically, while some need to be attached horizontally. For the most part, however, faucet water filters do tend to offer the same function: they filter contaminants out of the water to make it more drinkable.

Some faucet water filter models do tend to filter out more contaminants than others, and some even contain ion-exchanging resins so your water has a specific taste, but all filters make water that comes straight from your faucet a lot nicer to drink.

Different models also come with different prices, and it’s thought that the more expensive models can offer you a better quality of filtered water, but this is not always the case. Some slightly cheaper models are just as good as the more expensive ones, so you may not have to spend that little bit extra to get filtered water that tastes great.

Whether your new water filter comes with an electronic display, a flow selector, or Bluetooth capabilities, you can be sure that when you use a filter, water straight from your faucet will taste so much nicer.


Are faucet water filters worth it?

Faucet water filters help to remove pesticides, herbicides, chlorine, chlorine by-products, and pharmaceuticals from water. They also work to reduce bacteria, waste particles, lead, mercury, and other heavy metals that are often present in some old water pipes.

All of the above substances can cause the water to taste and smell odd, while also having a negative effect on your health. If you would like to drink water straight from the faucet, using a water filter will be worth it. Not only are they a lot cheaper than bottled water, but they’re also less harmful to the environment as well.

If you’re willing to pay approximately $23-$45 a month for a faucet water filter that will make water straight from the faucet drinkable, whilst working to reduce contaminants, in this respect, they are worth it.

How effective are faucet water filters?

Faucet water filters are very effective, as they remove many different contaminants, so that you can drink fresh filtered water, without having to buy an expensive water filter that’s kept in your refrigerator. Faucet water filters are known to be very effective, which is just one of the reasons why you see so many different types, brands, and models.

Most faucet water filters remove 96% of mercury, and 99% of lead, 92% of specific pesticides, and other contaminants. Others remove similar or a slightly lower percentage of lead and mercury, but they do remove them sufficiently so that the water you drink is clean, safe, and fresh-tasting.

What do faucet water filters remove?

As we have already seen, faucet water filters help to remove pesticides, herbicides, chlorine, chlorine by-products, and pharmaceuticals from water. They also work to reduce bacteria, waste particles, lead, mercury, and other heavy metals that are often present in some old water pipes.

While the environmental bodies work hard to control what goes into our water, sometimes contaminants do find their way into the water that we use. Whether it’s due to water coming into contact with lead pipes, pesticides, herbicides, and other substances, the water that comes out of our faucets is not as clean as it could be. Water filters can, therefore, make the water so much cleaner, because they work to remove all of those nasty contaminants that could prove to be quite harmful.

Once the contaminants have been removed/reduced, the water straight from your faucet should taste and smell so much better, making it a pleasure to drink.

How long do faucet water filters last?

Some water filters can last from 2 to 3 months, whereas others may last a little longer. If you tend to drink a lot of water, you may find that your faucet water filter doesn’t last as long as you may have thought.

Filters are usually capable of filtering 100-200 gallons of water, which is how much the average person drinks in a period of 1 to 3 months. Some water filters come with Bluetooth or another type of display that shows you how much life is left in the filter. These help you to determine how much water you can drink straight from the faucet before you need to replace your filter.

If you tend to drink a lot of water, it’s recommended that you choose a filter that can filter 200 gallons of water, as it will last you quite a long time. If you don’t drink a lot of water, opting for a model that filters just 100 gallons may be preferable, however, there is no reason why you shouldn’t purchase a faucet water filter that can filter twice as much.


The right faucet water filter for you will depend on your budget, and how often you drink water. There are a lot of different faucet water filters on the market right now, but we are confident that you will find the right water filter for you in the above list.
