What is a Kitchen Faucet Water Filter? 

A kitchen faucet water filter is a point-of-use (POU) water filtration system that provides clean, filtered drinking water directly at your kitchen sink. 

Most sink faucet water filters are designed to produce water on demand, so they do not include storage tanks. 

The filter immediately produces filtered water when the faucet is turned on. This type of water filter does not have any wastewater; all incoming water exits the system as potable water. 

Note that reverse osmosis water filters, which typically come with their faucet, have a tank that can hold an average of three gallons of water. 

Water filtration systems for kitchen sink faucets are installed directly on the faucet. You can install your water filter yourself but hire a plumber or handyman if you’d like. 

How Do Tap Faucet Water Filters Work? 

Filtration of tap water is a relatively simple process. First, examine how water typically reaches your faucet after entering your home. 

There are hot and cold-water pipes beneath your sink. When the faucet is turned on, water flows through these pipes and exits the faucet. Your home has a constant water supply, so if your faucet is functional, turning it on will always produce hot or cold water. 

Installing a kitchen faucet water filter at the cold-water pipe allows cold water to flow directly into the system for filtration. When water has been filtered, it exits the filter and ascends through an exceptional faucet designed to produce filtered water. 

Because it is not connected to the cold-water supply, a tap water filter will not filter the water that comes from a standard kitchen sink faucet. 

This means that using cold water from your standard faucet will bypass the water filter and flow directly up the cold-water pipe. Only when the exceptional faucet is turned on will water pass through the faucet water purifier for filtration. 

You will not have to wait for your kitchen faucet water filter to filter water. 

As soon as you turn on your faucet, water will quickly flow through your filter and out the opposite end. You should receive your water almost as soon as you receive unfiltered water. 

Advantages of Water Faucet Filters 

There are numerous advantages to installing a water filter on your home’s faucet. Among the key advantages are: 

Elimination of Dangerous Contaminants and Impurities 

A faucet water filter’s primary function is to produce clean, pure drinking water. Tap water filters can eliminate contaminants such as lead, bacteria, rust, dirt, heavy metals, and chemicals such as chlorine. 

While they shouldn’t pose a health risk in household drinking water, they can affect the water’s quality, and some individuals may choose not to consume them. 

If your home or business uses well water, faucet water filters can effectively remove the bacteria and other contaminants that are typically present in well water. Before making a purchase, contact the manufacturer if you are uncertain as to whether a particular faucet water filter will remove contaminants from your well water. 

Produces Delicious Water 

Many individuals purchase bottled filtered water because they dislike the taste of their tap water. A kitchen faucet water filter can eliminate the chemicals and contaminants that impart an unpleasant taste to water, resulting in clean, fresh, and delectable-tasting water. 

Water filtration systems for faucets are particularly effective at removing contaminants such as rust and sulfur that impart a distinct flavor, odor, and discoloration to water. 

If your water contains significant amounts of any of these contaminants, running it through a faucet water filter will make a significant difference. 

Space-Saving 

Because faucet water filters can be stored under the sink, you can save counter space while enjoying clean drinking water. 

While countertop water filters can appear bulky and unattractive, your under-sink cabinet conceals your faucet water filter, so you don’t have to worry about how it looks. Most faucets can be mounted to a wall or laid on their side to save space if necessary. 

Cost-effectiveness 

The initial cost of a water filter is relatively high, but compared to the long-term cost of bottled, filtered water, you can realize significant savings. 

In contrast, to reverse osmosis systems, faucet water filters do not waste any water during the filtration process, so purchasing a faucet water filter will not affect your water bill. 

Replacement filters are reasonably priced, and you will only need to purchase them every six months. 

Customized to Your Water Filtration Preferences  

Kitchen faucet water filters typically include multiple standard filters for removing contaminants such as chlorine, larger grains and sediment, and lead and bacteria. 

If you’re looking for a filtration system that provides more specific filtration, such as the removal of rust, you’ll be able to find it. 

You can also add additional filters to your existing faucet water filter, such as a remineralization filter that adds calcium and magnesium minerals to the water to reduce acidity. 

If your drinking water comes from a well, some faucet water filters are designed to render healthy water safe for consumption. 

How To Choose The Best Faucet Water Filter 

Consider the type of filter, the material, the flow rate, and the installation requirements before selecting a filter to make the best choice. Understanding these characteristics makes choosing the best faucet water filter for your home more accessible. 

Water Contaminants 

Pesticides, microorganisms, organic compounds, chemicals, pharmaceuticals, and harmful heavy metals such as lead, mercury, and arsenic are among the contaminants that may be present in tap water. Community-specific water contaminants vary, and knowledge is power. Using the Environmental Working Group’s National Drinking Water Database, investigate the factors affecting your water supply. 

Both chlorine and chloramine are frequently used to disinfect municipal water supplies. If the levels of chlorine and chloramine are too high, they can irritate the eyes and nose, as well as stomach discomfort. Due to their use in water treatment, most communities contain these contaminants in their drinking water. 

Some municipalities also add fluoride to their drinking water because it may be beneficial to dental health in small amounts. However, if the concentration of fluoride increases, it can cause pitting and discoloration of tooth enamel and even bone problems in adults exposed to it for an extended period. Occasionally, naturally occurring fluoride can be found in groundwater sources in the western United States and around the Great Lakes. 

When aging pipes begin to corrode, lead leaches into the public water supply and enters the water supply. Because lead pipes were a popular choice for city infrastructures before science caught up with innovation and it was discovered that lead is a toxic chemical that can cause neurological damage, impaired formation of blood cells, and impaired function of blood cells, this contaminant is widespread across the country. 

In rural communities, agricultural chemicals such as herbicides, insecticides, and pesticides protect crops. However, these substances can leach into the groundwater and contaminate nearby wells. Contaminating water can cause headaches, skin rashes, eye irritation, cancer, disruption of the endocrine system, and congenital disabilities. 

It is common knowledge that industrial chemicals produce hazardous runoff that can contaminate nearby well water systems and groundwater. Those with wells should consider the possibility of contamination, mainly if a nearby industrial processing facility is in an area susceptible to contamination. Well water that is contaminated can cause discoloration of the skin, damage to the nervous system, organ failure, developmental delays, congenital disabilities, and reproductive issues. 

Type 

Always verify that the filtration system can handle the contaminants that concern you the most. Regardless of which microorganisms they are most effective at removing, faucet-mounted filters significantly enhance the flavor of drinking water. 

Reverse osmosis filters are the most effective option for treating household water, as these systems can utilize more than seven distinct filters to remove up to 99 percent of contaminants. However, these systems are not designed for faucet installation. Directly connect reverse osmosis filters to the water supply. 

Typically, carbon filters are utilized in faucet-mounted products. These filters absorb and release water, while carbon traps chlorine, pesticides, and solvents. They are less efficient at eliminating nitrates and sodium. 

Another type of filter that does not attach to the faucet is an ultraviolet filter. However, connecting one of these filtration systems to the incoming water source is prudent. UV rays eliminate bacteria, parasites, and viruses. It is recommended to pair this system with a reverse osmosis system because these filters are ineffective at filtering mineral contaminants. 

Material 

Typically, faucet water filters are made of plastic or stainless steel. Some manufacturers may offer a variety of finishes, but these are generally stainless-steel filters that have been metal-plated to give them a different appearance. Thus, the choice is between plastic and stainless steel. 

Plastic faucet water filters are inexpensive and corrosion- and rust-resistant. Some products are thick and resilient, but the average plastic filter will need to be replaced more often than stainless steel filters due to their inferior resilience. 

Stainless steel faucet water filters are initially more expensive, but they last longer, perform better and have fewer leaks. These filters can also match the aesthetics of the kitchen’s faucet and sink. 

Volumetric Flow Rate 

Flow rate is the amount of water that flows through a filter in each amount of time, and it is typically measured in gallons per minute (GPM). Since most showers and dishwashers use up to 5 GPM, whole-house water filters must be able to filter a large volume of water per minute. 

However, faucet water filters have different water pressure requirements. Few of these smaller filters have a variable flow rate greater than 0.5 GPM. This is roughly enough water to fill seven or eight standard glasses in one minute. 

Filter Life and Usage 

Typically, the filter lifespan is specified in the product description or on the manufacturer’s website. After this period, the filter’s effectiveness decreases to the point where it hinders everyday faucet use. However, the real-life of a filter can vary significantly between products, even if they are identical. This is a result of usage. 

Filter life is directly proportional to usage. When the faucet is left running, water is wasted, and the filter’s lifespan is shortened, requiring the user to replace the filter cartridge more frequently. By only using the filter for drinking and cooking water, you can extend its lifespan and save money. 

Filter Cartridges 

When the filter loses its effectiveness, it is not necessary to replace the entire faucet-mounted filter. Remove the filter cartridge and install a replacement cartridge. Most manufacturers also produce replacement cartridges, making it simple to locate a compatible alternative. 

Depending on the product, these cartridges typically have a lifespan measured in gallons of water that ranges from 100 to 1,000 gallons. After a certain amount of water has passed through the cartridge, its effectiveness diminishes. Some filters also include cartridge replacement recommendations ranging from one to three months, eliminating the need to measure the amount of water passing through the filter. 

Style and Finish 

Most faucet water filters are made of plastic or stainless steel, but this does not prevent manufacturers from offering additional color options and metal finishes to match a home’s decor. 

Theoretically, plastic filters can be produced in various colors because plastic is simple to color during production. However, most manufacturers provide standard kitchen and bathroom hues, such as black, gray, and white. 

Stainless steel filters already have a sleek appearance, but if the kitchen has bronze, copper, brushed gold, or other standard metal finishes, it may be ideal to find a faucet water filter to match. The number of available finishes for a particular product depends on its manufacturer. Some manufacturers prefer to manufacture only stainless steel and chrome-plated goods. 

Additional Features 

After sorting through the specifics of filter types, filter materials, flow rate, and filter cartridges, there are just a few more factors to consider before choosing the best faucet water filter. Additionally, the filter size, the filter change sensor, and the replacement filter cartridges can impact the optimal filter selection. 

Smaller sink areas necessitate smaller filter sizes. Oversized filters may not fit properly and may cause problems. Even with a larger sink space, some filters can appear out of place if they are disproportionately more significant than the faucet. Consider the size of the sink and faucet when selecting a faucet water filter, and if necessary, purchase an adapter. 

Filter change sensors alert the user when it is time to replace the filter cartridge. This is typically indicated by a small light on the side of the filter that illuminates either immediately or a few weeks beforehand, allowing time to obtain a replacement cartridge before the old one becomes ineffective. 

There are a variety of replacement filter cartridges available. Prices can vary based on the manufacturer. Check the product information and the manufacturer’s website to locate the appropriate cartridge for a faucet water filter. 

Installation Requirements 

Typically, a faucet-mount attachment offers a quick installation. Unscrew the aerator and replace it with the adapter with the faucet-mounted water filter. Frequently, models include multiple sizes to provide options that may fit a faucet better. The faucet-mounted filter’s body snaps into place. 

The manufacturer’s instructions will detail verifying that the model’s filter is functional. It takes only a few minutes to install the most effective faucet water filters. Many filtration systems offer the option to switch between filtered and unfiltered water once installed.

Best Faucet Water Filter - FAQs

If you still have questions about the best type of tap filter or how to connect the water filter system to your faucet, continue reading to find the answers to these and other frequently asked questions. 

You can purchase faucet water filters from a local home improvement or do-it-yourself store, but the best option is currently the Internet. 

There are numerous options available from online retailers such as Amazon, or you can purchase directly from the manufacturers. If you begin your search on a manufacturer’s website, you should always check to see if the same product is available elsewhere for a slightly lower price, as this is sometimes the case. 

Always ensure that the seller you’re purchasing from can be trusted. Examine the seller’s product reviews, seller rating (if available), and past transactions to gain a deeper understanding of their level of trustworthiness and legitimacy. 

Personal preference determines whether tap water should be filtered. Filtering tap water removes contaminants from the water and improves its flavor, but filters’ cartridges must be replaced frequently to remain effective. 

The filtration capabilities of faucet and pitcher filters are comparable, so the choice comes down to a few key characteristics. Faucet filters are attached to the faucet and provide an almost unlimited supply of filtered water, although they can impede everyday faucet use. Pitcher filters must be refilled frequently, but water can be refrigerated or placed on a table or counter for easy access. 

In most cases, reverse osmosis systems are the most effective water filtration system. They can have more than seven filtration stages and utilize a reverse osmosis process that allows them to remove 99 percent of contaminants from the water, including chlorine, heavy metals, pesticides, and herbicides. 

Typically, faucet-mounted filters can be detached from the faucet, allowing you to transport them to a new residence. 

Some water purifier systems can be connected directly to a refrigerator, whereas connecting a faucet water filter to a fridge is impossible. This depends on the water purifier and refrigerator model. 

Faucet water filter cartridges should be replaced every 2 to 3 months to ensure the drinking water is cleaned correctly when passing through the water filtration system. If properly maintained, faucet-mounted filters have a lifespan of up to four years. 

The price of a water filter is not always proportional to its quality or filtration efficiency. It is prudent not to assume that you receive what you pay for, as a product may be priced higher for sales or marketing purposes. Keep in mind that some manufacturers may source their filter systems or components from overseas at much lower prices without mentioning the product’s origin in the description. 

You must conduct your research if you are considering purchasing a filter that costs significantly more or less than the average market price. Customer reviews can be helpful, but they should be taken with a grain of salt. Do not expect any product to be flawless and seek out studies that detail a filter’s flaws and benefits. This will provide a more accurate picture of filter quality. 

Yes, you will only need to turn off your water supply, disconnect the filter at the “T” section of the cold-water pipe, remove the faucet, and relocate the entire unit. From there, you can install it in the same manner as you did in your residence. 

After a filter change, cloudy water is not an ominous sign or something terrible. The air has become trapped within the filter housing and is mixing with the water. You can correct the problem by turning off your water supply and lifting your faucet before turning it back on, releasing any trapped air before water can flow back into the system. A 5-minute filter flush should eliminate any remaining cloudiness or milkiness in the water. 

There are a couple of reasons why your faucet may be producing water slower: either the water quality or water pressure in your home is significantly poor. 

In areas with inferior water quality, your water filter cartridges will fill much more quickly. Slow water flow indicates that you need to replace your filter, as it can no longer remove contaminants from the water effectively. 

If you have determined that the water quality is not to blame and that your filters should be functioning correctly, you may have a problem with the water pressure in your area. If your home’s water pressure is 30 PSI or less, your faucet filter system will struggle to force water through the filter media quickly. You can purchase a booster pump if your household’s water pressure is shallow. 

Installation is not easy, but it is possible either. Because faucet water systems are designed for do-it-yourself installation, you will not need to call a plumber for assistance. Installation requires patience and the capacity to adhere to directions. If you possess both, there is no reason you cannot attempt it yourself. 

Conclusion

In the end, searching for the best faucet water filter is never-ending. This is because new features and benefits are constantly added to newer water filter models. For example, more excellent smartphone connectivity via Bluetooth appears to be a future trend. 

However, it remains to be seen whether this trend will be nothing more than a fad. 

You will not be dissatisfied with any of the filters listed above, regardless of which faucet water filter you choose to purchase. Why? Because all the best water filters are effective. The harsh reality is that there is typically slight difference between them regarding water purity and flavor. 

However, minor differences in personal preference should help you make the best purchase.
