Why a Faucet Water Filter?

Faucet filters are a great alternative to whole-home water filtering systems. They are much more affordable, and the maintenance is less with a filtering faucet. They are also much preferred to other options like filtering pitchers or under-sink filtration systems.

Self-filtering water pitchers take up space in your refrigerator, and there is a limit to how much clean water you can have. Faucet filters are easily attached to your kitchen sink and require very little maintenance. And because they are connected directly to your water line and sink, there is no limit to how much water you can get at one time.

How Do Tap Water Faucets work?

One of the reasons why tap water faucets are so popular is because of their simplicity. Most models are easily attached to your existing faucet, and you will have the option of choosing filtered or unfiltered water. You may choose to use filtered water for drinking and unfiltered for dishes and other cleaning reasons. Having the ability to choose between one or the other is great.

The filter itself is built into the attached tap device and uses the pressure from your current kitchen sinks water. The water will run through the filter and then out of a faucet like normal. There is a maximum amount of water that can go through tap water faucet filters in a day. However, this is usually a very high amount of water, and most families won’t reach it.

Types of Faucet Water Filters?

There are a few different types of water faucet filters that you can choose from, although one is far and away from the most popular.

The most popular type is a device that is attached to your current sink and has a filter built into it. Installation is simple with these models, and the user will have the choice whether they want to run their water through their filter or let it come out with no purification. The reason they are the most popular is that they are effective, yet extremely simple to maintain and install.

The other option you can choose is a normal-appearing faucet that is attached to an under-sink water filter. It is a dedicated faucet you install onto your countertop

Buying Guide: What to Consider When you Buy a Faucet Mount Water Filter

Size

Because faucet-based water filters are going to be attached to your existing faucet, you need to make sure that the size of the filter isn’t going to be a burden. It is a common misconception that the smaller the filter cartridge, the fewer contaminants that it can remove. This isn’t necessarily the case. You will want to be fully aware of the physical size of your faucet filter and make sure it fits in your sink.

Style and Finish

When it comes to choosing the style of your faucet filter, you will have a few options depending on the manufacturer. Many of the popular twist-on style faucet water filters are made in a specific plastic membrane that adds additional water protective layers to your filtering.

Unfortunately, this only comes in plastic colors which some people see as an eyesore. There are a few manufacturers that prefer to go with food-grade stainless-steel because it has a better appearance. These have a much more luxurious appearance to them.

Water Flow

One of the reasons why people are turned away from water filtering faucets is because they are worried that their flow rate will plummet. The flow rate will be lessened with any filtration system because the water must go through multiple stages where impurities are being removed.

But some faucet filters are better at handling a consistent flow rate than others.

This information will be available to you before you decide on your perfect faucet filter. One thing to keep in mind is that your water’s flow rate will be affected by the PSI within your water system. This, along with the flow rate rating of the faucet filter are extremely important characteristics.

Filter Change Sensor

Knowing when to change the filter is one of the most forgotten parts of maintaining your faucet water filter. Luckily for us, filtering companies are coming up with more and more ideas to make sure that we do not ignore the filter changes.

The best option is a sensor that will tell you what the status of your filter is. Many of them will have an LED light that will blink green when the filter is in good shape, yellow if it needs to be replaced soon, and red if it is time for a replacement.

The other options are stickers that the manufacturer will send that you can write the date of the filter change. This is by no means the best option these days, but it is still effective at tracking filter usage based on a time frame.

Filtration System/Quality

This is arguably the most important aspect to investigate when deciding on the best water faucet filter for you. We strongly suggest that you find the faucet filter that removes the most common contaminants within your specific water system.

Different filters will be better at containing and eliminating more toxins within your water supply. To know exactly what you are dealing with in your water, you should get a water test completed. This will tell you exactly what your impurity levels are and what you want to ensure your faucet filter can remove from your water.

If you are looking for more than just an impurity filter, there a few faucet filters that can add minerals and alkaline elements into your drinking water supply. When it comes to quality, these models can remove tons of contaminants and provide valuable minerals and increased pH levels within your water.

Filter Longevity and Usage

When it comes to saving money and getting the most out of your water filter, you want to investigate the maximum lifespan of a filter. They are designed to be used for a specific maximum amount of water and after that point, they will slow down your water supply and not remove as many toxins.

Filter life ranges from 100 gallons to over 500 gallons, depending on the manufacturer. You need to consider the amount of water you will run through your faucet filter daily.

This will make sure you are not buying one that will need to be replaced too often, which will cost more money in the long run. Make sure you consider the number of people in your home to account for everyone’s water usage.

Filter Cartridges

As a homeowner, there are a few things I like to investigate the filters and the materials used to build them. Each filter has a housing around it referred to as a “cartridge.” These can be made from a wide variety of materials, the most popular one being a coconut membrane shell.

These types of cartridges add extra benefits to the filtration process by having anti-bacterial properties that will kill mold and bacteria build-up around the filter. I always look for filter types that have coconut membrane shells.

Years ago, cartridges were made from plastics that could add unwanted toxins into your filter system. One thing that is important to me is to ensure that is no chance of there being any added elements that could enter my water supply. Always ensure this when selecting the best faucet filter for you.

Cost

Like anything we buy for our homes, the cost will be an important part to consider. If you are looking at a faucet water filter, you are making a good financial decision because they are a very affordable water filtration option.

With prices starting around $20, you can have cleaner, fresher water for cheap. The higher-end faucet filters will be more expensive, obviously, but you will see that the higher-end filters tend to have alkaline filters included.

One thing to investigate before you decide on the best water faucet filter is the price of the replaceable filters. They will vary as well, so you will want to make sure that the filter that comes with the faucet does not cost an arm and a leg to replace.

Installation

The beauty of the faucet filter is that it was designed to be installed and maintained entirely by the homeowner. Most of the more modern faucet filters simply twist onto your current faucet. Not all faucet heads have the same thread sizing and patterns, so the faucet filter may not twist-on right away. Luckily, most manufacturers include a few adapters to account for each thread type and faucet size.

One thing to remember is that twist-on faucet filters will not work with all faucets. If your faucet has a spray function built-in, be careful because most faucet filters only work with standard, static faucets. Most of this information will be on the packaging of the filter faucet you choose, just make sure to read all the fine print!

Filter Cleaning and Replacement

Finding the best faucet filter for you includes finding a model that has filters you are comfortable replacing and cleaning is very important. Cleaning the filters is extremely important to remember because there will be times when they get backed up and just need a quick rinse. Most filters can be cleaned with cold water, which makes it easy for everyone.

When it comes to replacement, that can be tricky with a few different brands. Now, all filters come with tool-less install and uninstallation, but it is still important to find a model you are comfortable with.

My favorite filters are a push-button type that unlocks the filter from its spot when you press and will easily allow you to remove it. Some other styles are twist-lock, which works great as well.

This is a hotly contested debate among the plumbing and water filtration industry. Brita was the original when it comes to many water filtering items.
