Things to Consider When Selecting Faucet Water Filter

best faucet water filter for well water

There are a few things you ought to know if you are shopping for a water filtration system for your kitchen. From type to price and features, here are some of the things to consider if you want the best faucet water filter for your household:

Water Quality

The first thing you need to do before buying a water filtration system for your home is to test the quality of water in your taps.

For instance, if your primary source of water is a borehole or well, you should select a filter that’s optimized to purify hard water over soft water.

You can even go a step further and have the water screened by certified professionals to help you identify the salts, minerals, chemicals, sediment, and other pollutants in your water.

Based on the data provided, you can confidently select a certified filter that purifies your drinking water by eliminating all the contaminants found.

Types of Installation

There are four main types of water filter installation. Here is a brief look at each type:

  • Faucet-mount: They are installed on the faucet and provide the versatility of switching between filtered and unfiltered water. While cheap, you cannot install these filters on most spray and pull-down faucets. The best faucet water filter consumer reports are the Pur Vertical FM-3700 and Culligan FM-15A.
  • Countertop: As their name suggests, these filters are placed on countertops. One advantage of the best countertop water filter is that you can place it on any worktop area you desire since it doesn’t require any plumbing. Their downside is that they cost more than faucet-mount filters and eat into valuable countertop space. Just as with faucet filters, you cannot fit most spray and pull-down faucets on this type of filter.
  • Undersink: They are installed under sinks or under countertops. They are ideal for those people that value a clutter-free worktop area. The downside with undersink filters is that they are the most expensive types of filters. They are also the hardest to install and are a headache when it comes to replacing old filters.
  • Pitcher: They are the cheapest and most common type of water filters. They don’t require any type of installation and are mostly used for purifying cooking and drinking water. The best water purifier pitcher should compact, lightweight, portable, and effective at purifying water. The downside of pitcher filters is their limited water capacity and their slowness in filtering water.

The porousness of the Filter

One thing you should be wary of is the porousness of water. Sure, filters should have tiny holes to trap all forms of contaminants.

However, the tinier the holes the harder it is for water to pass through and the faster the filter clogs. This can greatly reduce your water’s flow rate.

A good filtration system should have a perfectly balanced porous filter that doesn’t clog easily and doesn’t slow down your water’s flow rate.


Price is a huge factor when buying a filter for your kitchen faucet. It is important to remember that the faucet filtration system requires you to replace their filters periodically.

Therefore always consider the price of the replacement filter. Some brands offer filtration systems with incredibly low initial costs but charge extremely high prices to replace filters.


Nowadays, faucet filters come equipped with some of the most ridiculous but innovative features. Granted, some features are hits with consumers and been adopted as industry standards while others are nothing but gimmicks.

That said, here are some of the most useful features to have in your brand new faucet filter:

  • Filter Life: On average faucet filters can purify between 100 and 300 gallons of water before replacement. That is about three to five months of clean, purified water on an average household of about five people.
  • Filter Detection System: This is an incredibly important feature to have in your filter. Nowadays, these filters are equipped with LED display systems that show the status of the filter and notifies you when to replace the filter.
  • 360-Degree Swivel: A good filter should have a full-swivel feature to give you more access to filtered water within the sink.
  • Spot Resistance: If you’re a perfectionist, you should go for a faucet filter that has a spot resistant finish. The spot resistant surface protects the filter from unsightly water and fingerprint marks leaving your kitchen looking sharp and tidy.

Types of Faucet Water Filter:

types of faucet water filter

There are five distinct types of faucet water filter systems. Here is a brief look at how each of them works:

  • Activated Alumina: These filters are made of Aluminum Oxide as the purifying agent. Activated aluminum filters are cheap and remove up to 99 percent of fluoride, selenium and arsenic compounds in drinking water.
  • Activated Carbon: Also known as activated charcoal, these filters use processed carbon compounds that are heat-treated to maximize their filtering capabilities. They are designed with tiny, microscopic holes that excellent at filtering out sediment, and other volatile organic compounds (VOCs) to improve the odor and taste of drinking water. While activated carbon filters are cheap, they are poor at removing salts, minerals, and other dissolved inorganic compounds.
  • Ceramic: These filters are made of tiny-pored ceramic materials that are treated with silver. The microscopic pores keep out sediment while the silver compound kills bacteria in drinking water and prevents the formation of algae and mold. Ceramic filters are cheap but not effective at dealing with viruses in water.
  • Reverse Osmosis: These filters use a membrane with tiny microscopic pores. Water is forced through the pores to rid it of all pollutants including viruses, parasites, chemicals and heavy metals. The only downsides to reverse osmosis filters are they are expensive, bulky and require a lot of water pressure.
  • Ultra-Violet: These filters work by passing water through their specialized glass elements and blasting the water with UV rays to kill all parasites, viruses, bacteria, and other microorganisms. That said, ultra-Violet filtration systems are expensive, require power and don’t filter out non-living pollutants such as dissolved minerals and salts.

Benefits of Faucet Water Filter:

Installation of Faucet Water Filter:

  • Step 1: Turn off the water supply from the shut-off valve to prevent accidental water spillages
  • Step 2: Next, unscrew the faucet aerator. It contains a rubber washer and wire mesh inside it to filter debris and control the flow of water.
  • Step 3: Once the aerator is out, take a damp cloth and clean the faucet threads. Remove rust and debris from the threads to ensure the filter screws on tightly and securely.
  • Step 4: Check whether the filter and other components of the Filter attachment kit are in place as directed by the installation manual.

  • Step 8: You’re all set up at this step. Inspect the water flow and make sure there are no leaks. If there are contain them and you’re good to go.

Cleaning & Replacement of the Faucet Water Filter

If you’ve never owned a water filter before, it is important to remember that the filters need to be replaced over time so you may continue to enjoy clean water.

The lifespan of filters varies with different brands and how you use them at home. Some can last months while others years.

Therefore, it is important to read your water filter’s instruction manual to determine the due date for your filter replacement.

If you own one of the newer better water filter kits, you’re in luck as maintenance is a breeze.

Most of these newer generation faucet filtration systems come equipped with electronic systems that monitor the status of the filter and notifies you when a replacement is due.

As time goes by, the filter continues to deteriorate and that information is captured by the electronic monitoring system.

Unfortunately, you cannot clean and reuse filters. However, this real-time information allows you to prepare yourself in advance so you can buy replacement filters before the current ones become ineffective.

When replacing the filters in the filter attachment kit, use the steps highlighted in the previous section. Ensure you clean all residue as you take the filter system apart then sterilize them with hot water to achieve perfect results.

Frequently Asked Questions:

1. How often do I have to change the filters?

There’s no definite answer to this question. You should replace the filters based on the model you have and how often you use it. If you’re lucky enough to own a new generation faucet filter, it will automatically notify you when to change the filters.

However, if you’re stuck with an older generation model, you have to study its instruction manual. The manufacturers typically indicate the specifications of the filters.

This includes the amount of water a filter can purify before it becomes ineffective.

On average, home-based faucet filters can clean between 100 and 300 gallons of water. If you are clueless as to what that means, the manufacturers issue a timeline on when you should replace the filters.

Again, on average, most filters can last anywhere between two and five months of regular use before they become ineffective.

2. What should I do with the used filters?

You can either reuse or recycle old water filters. While ill-advised, some people clean used filters with bleach so they can re-use them.

This is not something I would recommend to anyone. The other more sensible option is to recycle the filter.

Some manufacturers provide recycling services so you can either drop the used filters at their dealership or place it in your recyclable garbage section for collection.

3. Does my water filter remove limescale?

Limescale build-up is not something that can be prevented especially in hard water faucets. However, all water filters have the capacity to trap limescale and keep it from escaping the faucet.

That said, when limestone builds up, it forms residue within the filter slowing down the water flow rate. You will be required to replace the filter and clean the plumbing to prevent its formation.

4. What happens if I do not replace my water filter?

The most obvious thing is that that the filter will become ineffective and with time become useless. It is likely that the microscopic pores of the filter will clog with sediment and other impurities.

This will reduce water flow and over time block completely so that no water passes through the filters.

Another case scenario is that the water will erode the microscopic pores making them larger. This will allow bacteria, viruses, and other toxic microbes to pass through making you sick.
