Faucet Mount Water Filter Buying Guide

New -faucet water filters

Finding the right faucet water filter can be difficult in today’s crowded market. Every manufacturer claims his products are the best but do you really know if that is the truth or just a marketing scheme?

To help you in your decision making, we decided to create a short buying guide. This guide will reveal the most important features of a faucet water filter, and it will explain each one individually. After reading the buying guide, you should be able to make an informed decision and choose the best water faucet filter for your home.

The Top 7 Things to Consider When Buying a Faucet Water Filter!

  1. SizeFaucet water filters usually have roughly the same size, but some models are slightly larger than others. The size of the filter is closely related to the size of the water filter cartridge. The larger the cartridge, the larger the filter.The size of the faucet filter is not very important to the way the filter actually works. However, the size of the filter is very important to how much space it will occupy. Maneuvering dirty plates around a water filter is not an easy thing to do if your kitchen sink is tightly packed, so you should look for a smaller model.If your sink allows you plenty of room to move around, there should be no problems if you choose a large filter.
  2. FinishNow, most of the faucet water filters we reviewed work in a similar way. They don’t look similar though, so you should be careful when you decide on one. The water filters come in different finishes, and you shouldn’t encounter any problems looking for a finish that matches your other fixtures and appliances.We have a recommendation when it comes to choosing the right finish for the water filter. Try, when possible, to avoid choosing the white plastic finish. This finish rarely matches anything in your kitchen, and it might look off. You should always try to choose a finish that at least matches your faucet.
  3. Ease Of InstallationThis is an important feature of a faucet water filter. The fact of the matter is, most of them are very easy to install, and you won’t even need a tool to install them. However, you might need an adjustable wrench to unscrew the aerator off your faucet if you can’t do that by hand.Some water filters do need some tools or materials for the installation, but most manufacturers include everything you need in the product’s box.It’s important to have an easy to install filter because you might need to take it off when you need to change the filter cartridges. This is not a necessary step in the replacement process, but the filter’s position might make the change more difficult.
  4. StyleFaucet filters manufacturers usually design their products to fit in two styles. One will allow the filters to rotate around their axis. This is a nice feature because it will allow you to move the filter out of your way when you’re doing dishes. The second style doesn’t allow the filters to rotate around their axis, but it allows them to swivel on the vertical axis. This also allows you to have an unhindered access to the sink when you need it.Since both styles allow you to use the faucet without getting in the way, they are both good, and it’s only a matter of preference if you decide one or the other.
  5. CostAll the faucet filters we reviewed are decently priced. Some of them are even cheapHowever, you shouldn’t look only at the buying price of the water filter. When you decide on a filter model, make sure you take a quick look at how expensive the replacement cartridges are. Some cartridges are cheaper than others and they will lower your maintenance costs significantly.
  6. Filter CartridgesThe filter cartridges are the most important components of the faucet water filters. They are the ones that remove the contaminants from your drinking water. This is why you should know more about them before you make a purchase.Most of them are heavy-duty cartridges that remove most of the contaminants in the water. Some are so efficient at removing contaminants, they can eliminate up to 70 different substances from your drinking water.However, the filter cartridges have a limited lifespan. Some of them come with a recommended filtering capacity, like 100, 200, or 300 gallons. These models most often use a filter change sensor to notify you when to change the filters. Other models come with a periodic filter change recommendation, so you know you have to change them every 1, 2, or 3 months. A few have mixed recommendations, so you can either change them after they filtered 200 gallons of water or once every two months.You should always respect the manufacturer’s filter change recommendation. The filters pass several tests before they are released on the market, and if you respect the recommendations, you can be sure you’re always drinking healthy filtered water.If you don’t follow the recommendation and fail to change the cartridges, you can drink contaminated water instead of filtered one.
  7. Filter Change SensorsMost manufacturers implement filter change sensors in their products, so they will notify you when it’s time to replace the filter cartridges. There are two types of sensors used for faucet water filters
    1. Light Sensor
      – This is the most common filter change sensor, and you can find it in different shapes on many products produced by different manufacturers. The colors used by the sensors are the same, though, so you can use them all in the same way. The sensor’s light starts off as green. When the filter cartridges are close to their maximum filtering capacity, the sensor’s light turns to yellow, so you know you have to order a new cartridge, or so you can go to your local shop and buy one. When the filter reaches its maximum filtering capacity, its light will turn red. When the sensor’s light is red, the water you drink won’t be completely filtered, so it won’t be as healthy.
    2. Day Counting Sensor
      – This type of sensor is usually used for water filter pitchers, but there are some faucet water filters that use it as well. This sensor counts the days since you last changed the filter cartridge. When you change the cartridge, you reset the counter.
    This sensor doesn’t notify you when it’s time to change the cartridge, but you can read how many days passed since you last changed them every day, so it’s still easy to keep track.

How Tap Faucet Water Filters Work

Faucet water filters provide an effective solution to remove the contaminants from your drinking water. However, some people confuse the terms water filter with water purifier, or they consider them synonymous. This is far from the truth.

What A Water Filter Does

Water Filters

A water filter removes some of the contaminants in a water source. The number of contaminants removed depends on the filter’s efficiency and the quality of the water.

A water purifier makes sure that less than 10% of the contaminants in a water source reach the faucet. However, to achieve this, a water purifier uses more water filters.

As you can see, there is a difference between the terms. They actually describe different products. When it comes to water filters, faucets water filters are considered effective. They are capable of removing 10 – 20% of the contaminants in the water.

However, some contaminants will be removed in larger proportions than others. That’s why the filtered water will contain little to no traces of sediment, chlorine, or rust. These contaminants will be greatly reduced or eliminated by the water filter, but some will only be removed in a small amount. For example, some viruses and bacteria can pass through the filter unscathed.

How Does A Faucet Water Filter Work?

Well, no matter how they’re called, most faucet water filters work in the same way. They use different layers to remove some of the contaminants in your water source, and they do it fast.

When you turn on the faucet, the water passes through a filter screen that protects the water filter. This screen can be made out of woven or non-woven mesh, and its role is to block the larger contaminants. This is where the rust particles, sand, debris, and dirt stops.

After the water passes through the screen, it reaches the second layer. This is usually a thick block of compressed activated carbon. Activated carbon is made out of nut shells, wood, peat, coconut husk, or lignite, that is activated through a physical or chemical process.

Most faucet water filter manufacturers prefer using charcoal activated through a chemical process, which implies impregnating the carbon with certain chemicals. Some of the chemicals will also grant some additional properties to the carbon, so it will be more effective at killing bacteria.

The activated carbon is very porous. In fact, the carbon is so porous that just one gram of carbon has the equivalent surface area of 32,000 square feet. The whole surface of the carbon is full of nooks and crannies, and thanks to a natural process called adsorption, the contaminants are attracted to the carbon’s surface.

When the contaminants reach the activated carbon layer, they are attracted to its surface, and they will enter its pores. They will be trapped there, and your water will be less contaminated.

The more time the water stays in contact with the carbon filter, the more contaminants are blocked. This is why most water filters reduce the faucet’s water flow dramatically, so the water spends more time in contact with the carbon filter.

After the water exits the carbon filter, it reaches the faucet and it’s suitable to drink.

What Does The Faucet Water Filter Block?

You might be wondering what a faucet water filter is capable of blocking, and what it’s not.

Well, we have good news for you. First of all, the water filter will remove the chlorine from the water. This will greatly improve the water’s taste.

Second, the filter will also remove most of the large contaminants like dust, rust, sand, and other debris. This will also improve the water’s taste, and it will make it healthier.

The activated charcoal filter is also very good at removing the volatile organic compounds in the water and the smaller sediment that might have escaped the first screen. Treated charcoal can also remove some bacteria and viruses.

Lastly, the activated carbon filter will remove all the weird tastes and odors in the water, making it healthier and easier to drink.
