Under Sink Water Filter Buying Guide

Knowing how tough it can be to decide whether or not you should install an under counter water filtering device in your home, we understand your frustration. In addition to looking through the numerous options available to locate the best undersink water filter to meet your needs, you need also consider

As a result, I’ve put together the following purchasing guide.

This shopping guide, which includes under-sink water filter reviews, is intended to assist you in making the best educated decision possible about your water filter purchase.

1. Woder WD-S-8K-DC

It is a WQA approved undersink water filter that can remove impurities that affect the odor and taste of the water, such as chlorine, as well as heavy metals, such as lead and chromium. It is available in two sizes: small and large. It has a flow rate of 2 GPM, which is reasonable for an under-sink unit of this size.

There is no doubt that the most compelling selling point of this multi-stage system is its extremely high capacity, which may last up to three years, or around 8,480 gallons. Using it with municipally treated drinking water, rather than well water, will ensure that it lasts for the longest time possible.

 

For the installation of the Woder WD-S-8K-DC, you do not need any plumbing skills or experience. You may just link the direct connect hoses to any US water valve under the sink of your choice, and you’re done (bathroom sinks included).

 

The filters themselves are made using a proprietary technology that allows them to remove 99.9 percent of lead and chlorine, as well as a significant amount of other impurities, all without eliminating beneficial minerals from the water supply. For those who desire maximum filtration without sacrificing essential minerals, a filter like this Woder system will be more effective than an other reverse osmosis system in this situation.

2. APEC WFS-1000

In addition to using NSF certified parts and filters, the APEC WFS-1000 can minimize or remove a wide range of pollutants found in tap water. In the United States, the device is created and manufactured, and it removes pollutants such as chlorine, which can impart an unpleasant taste and odor to water.

WFS-1000 is equipped with three filters: two carbon block filters, which are responsible for removing chemicals as well as taste and odors, and one sediment filter. This section of the system is responsible for the removal of dust, rust, and other particles. In addition to the new faucet that comes with the unit, if you don’t want to risk leaching after filtration, you can choose to install a new faucet that is not required for use.

Incredibly, each filter in the APEC WFS-1000 is designed to endure for 12 months – an astounding feat considering that some filters from similar devices on the market promise to last for three or even five years. Replacement filters are available for purchase online; they range in price from $50 to $100 for multi-packs of 2 or 3.

This filter does not require the use of a tank, and tap water flows directly through the device and out of the faucet, requiring no additional time on your part on your part. You don’t have to rinse or flush your cup because all of the water that runs through the system ends up in your cup, saving you money and water in the process.

3. Filtrete Under Sink Water Filtration System

For the removal of aesthetic impurities and health-related toxins, the Filtrete undercounter filter has been approved by NSF 42 and NSF 53 laboratories. This provides confidence that the unit can effectively remove or significantly reduce contaminants such as chlorine, volatile organic compounds (VOCs), microbial cysts, and lead.

Because there is no requirement to connect the Filtrete to a specialized or conventional faucet, it may be installed virtually anywhere, including any kitchen or bathroom faucet. The installation process takes approximately 30 minutes, and because of the system’s simple push-fitting connections, you do not need to be an expert to complete the work successfully.

The Filtrete’s filters have a maximum filtering capacity of 2,000 gallons, which means they have a lifespan of around 6 months after being installed. Water flow will not be a problem when you use this filter, which filters under sink water at a rate of 2.25 GPM, according to the manufacturer (gallons of water per minute). Interestingly, this is more than the usual GPM of a faucet, which is approximately 1 to 1.5 GPM (gallons of water per minute). Replacement filters are available for purchase on the internet.

Installing the device is made simple by the manufacturers, who have created a video to demonstrate how to do it. Written instructions are also included with the unit and are available online. All that is required is that you connect the water supply hose to the filter head’s input and output connectors, and then screw the filter into the filter head.

4. CuZn UC-200

It has an unbelievable capacity of up to 5 years per filter, which makes the CuZn UC-200 Under Counter Water Filtering Unit a high capacity 3-stage under counter water filter with an incredible capacity of up to 5 years per filter. This filter, which is intended to purify municipal water (rather than well water), connects directly to the water line underneath your kitchen sink and is easy to install. Installation takes simply a few minutes, and the only equipment you’ll need is an adjustable wrench to fasten all of the connections together.

The counter water filter CuZn filtering system removes chlorine, heavy metals, silt, herbicides, pesticides, algae, and bacteria using a three-stage filtration process. It is also environmentally friendly. It makes use of KDF and coconut shell activated carbon filtration elements to clean water without eliminating essential minerals such as calcium from the water. Please keep in mind that using a TDS reader after using the CuZn countertop water filter is not a reliable method of assessing water quality because it does not remove all TDS in the same way that reverse osmosis systems do.

The CuZn under-sink water purifier employs a bacteriostatic filtering mechanism, rather than a carbon-only system, to purify the water. In addition to being less sensitive to bacteria and mold growth, this type of multi-stage system doesn’t do anything to soften or eliminate hard water minerals – for that, you’ll need to invest in a reverse osmosis filter or a water softener. As an alternative, it enhances the taste of the water and makes it safer to drink.

5. Frizzlife Under Sink Water Filter System

The Frizzlife is a water filtering system that can remove up to 99.9 percent of chlorine taste and odor, as well as lead, from drinking water when installed under the counter. For the elimination of aesthetically objectionable impurities and potentially harmful contaminants, the unit has been evaluated by IAMPO R&T, an independent third-party research and testing business, in accordance with NSF 42 and 53.

The unit makes use of a single filter cartridge that performs the duties of two separate cartridges. It goes through two stages of filtration: a first stage that uses a 0.5 micron sediment filter media to remove particles like sand, rust and silt, and a second stage that uses a 0.5 micron carbon block filter media to reduce heavy metals, chlorine, volatile organic compounds (VOCs) and other particles.

With the Frizzlife’s highly compatible fittings, installation is a breeze, and the only maintenance you’ll have to worry about is replacing the filter after about 12 months of use. Because the filter has an automatic shut-off button, you won’t have to turn off your entire tap water supply while performing this maintenance. There is a video available online to guide you through the filtering process, which takes approximately 3 minutes to complete.

According to NSF Standards 42, 53, 401, and P474, the unit has been proven to reduce or remove chlorine, lead, volatile organic compounds (VOCs), Giardia, pesticides and herbicides, prescription medicines, detergents, and PFOA and PFOS from drinking water and wastewater.

The system can remove up to 99 percent of water than 70 pollutants, but it will not remove total dissolved solids (TDS), which will require a reverse osmosis system. It has a high flow rate, around half a gallon of water per minute, which allows you to have fast access to clean water from your faucet when you need it.

Every 6 months, you will need to replace the filters, which is not the longest lifespan we have observed for an under sink filter. The filters, on the other hand, are extremely simple to replace, and there is no need to separate the unit from the water supply — you simply remove the old filters and snap in the new ones.

Everything you need for installation, as well as the first set of filters, is included with the Aquasana under counter filter. Even if you don’t have much experience with DIY projects, you won’t have to hire a plumber to complete the task for you.

What is a Kitchen Sink Water Filter?

When it comes to under counter water filters, these are point-of-use systems that are positioned underneath a kitchen sink and are designed to filter water directly at the point of use.

Designed to produce a limitless amount of water on demand, these filters may produce an unlimited amount of water. This means that they begin working as soon as you turn on your faucet and create water that is ready to drink immediately.

It’s important to note that an under-sink filter is not the same thing as a reverse osmosis system. During your search for an under-sink unit, you may have come across the term reverse osmosis (RO) filters. This is due to the fact that reverse osmosis units can easily be put beneath a kitchen sink. Reverse osmosis systems, on the other hand, operate in a completely different manner.

Instead of producing wastewater like reverse osmosis systems, under-sink filters are meant to filter water directly without the need of chemicals. However, reverse osmosis is more expensive and provides a more comprehensive filtration process. Under-sink filters are often far less expensive than reverse osmosis systems. RO systems are much more expensive to maintain than other types of systems.

All of the water that enters an under-sink system is converted into potable drinking water at the other end.

The filter is attached to a water line that runs under the sink. Water travels from this pipe into the pressure filter, where it is cleansed and redirected back up to the faucet through a separate pipe as pure drinking water.

A unique faucet for producing filtered water that is separate from the hot and cold faucets in a sink area may be provided. Modern under-sink faucets, on the other hand, are increasingly widespread in that they divert the full cold water line supply from the sink to the filter before it reaches the faucet itself.

This implies that there is no need for a separate faucet, and all water from the faucet is filtered, while the hot water is left unaffected by the filter.

Why use an under counter water filter?

Improves water taste

However, while many people will not acquire a sink filter just for the purpose of improving the flavor of their water, it is an additional benefit that should not be overlooked. Removal of pollutants and contaminants that might cause water to taste or smell terrible, such as chlorine and sulfur – which are responsible for giving water a rotten egg smell – will not only make your water safer to drink, but it will also improve the taste of it.

Removes contaminants and impurities

In some areas, your water may contain a variety of harmful contaminants and impurities, including bacteria and viruses, chlorine, pesticides and herbsides, lead and heavy metals, as well as larger particles like dirt and rust. In other areas, your water may contain no contaminants or impurities at all.

Using the best under sink water filter is the only method to assure that all of the undesirable elements are removed from your drinking water.

Using several filters in your system, you will be able to successfully remove a wide range of different impurities, resulting in water that is fresher, cleaner, and safer to consume.

Cost-Effective

With an under counter water filtering system, you may put an end to your bottled water spending spree that has been going on for as long as you can remember.

You will be able to enjoy the flavor of your own tap water with the knowing that you are no longer consuming harmful water toxins such as lead, chlorine, and heavy metals, as a result of this procedure.

In comparison to purchasing multi-packs of treated water bottles from the shop on a weekly basis, replacing your filters on a periodic basis will be significantly less expensive.

Undersink filters are also less expensive to acquire than other types of water filtration systems, they endure for a longer period of time, and they are generally more efficient.

Space saving

Under counter water filtration systems are a good option if you don’t have enough counter space for a countertop water filter, or if you simply don’t want anything bulky taking up valuable counter space on your vacant surfaces.

While it will still require you to make some space for it in your under-sink cabinet, it will not require you to have it on display in order for it to perform its functions efficiently.

How to Buy an Under Counter Water Filter

The majority of under-sink water filters are available for purchase online or at home improvement retailers. Nowadays, most people shop online because there is a greater variety of options to pick from and because there is less pressure to make a purchase when shopping online.

If you’re interested in a certain product, you should read through all of the under sink water filter reviews that are available for it and compare costs, features, and the companies that make the product in question.

Do not be afraid to contact the manufacturer directly if you have a query that is not answered in the product description or FAQs when it comes time to make your purchase.

Considerations to make when purchasing an under-sink water filter

In order to get the most out of your system, you should think about a few factors before making a decision. Considering the following characteristics while determining which product is best for you is recommended:

Type of Filter

The ease with which you can install your system will be determined by the sort of system you purchase. Simple kitchen sink filters are less complicated to install since they do not necessitate the installation of a separate faucet at your kitchen sink.

The traditional method of filtration directs water to a different faucet, which is typically included in the package. It’s possible that you’d choose to purchase a straightforward under-sink water filter based solely on installation considerations, but conventional systems have their advantages. If you want to have the option of having both hard and soft cold drinking water available at the same time, having two different faucets will provide you with that option.

Measurements

Your under-sink measures must be matched to the measurements of your system to ensure that the unit will fit comfortably in the available area.

The size and shape of some under-sink filtering systems differ significantly from others, and if you don’t have much extra space to spare, you might want to select a more compact system with smaller filters that perform a variety of functions in one unit.

Ease of installation

The majority of under sink filters will come partially assembled, and you’ll only need to connect the system to your cold water pipe at the right locations. Read up on installation for your particular model to be sure exactly how the installation process will work.

Keep in mind that if you’re looking to purchase a conventional system, installation will be more complex because you’ll be required to fit a faucet at your sink specifically for the filtered water to run through.

Installation & maintenance costs

Whether you decide to install your sink water filtering system yourself or hire a handyman, you’ll need to budget for the costs of doing so.

For maintenance purposes, most sink water filtering systems only necessitate the replacement of their filters when they are no longer operating effectively. New filters will increase the cost of your system, but they are necessary for it to function well for the foreseeable future.

Certifications

Obtaining accreditation from the NSF/ANSI or the Water Quality Association (WQA) are the two most important certifications that a manufacturer of an undercounter water filtering solution can achieve. This and the certification of third-party testing inform customers that a product has been thoroughly examined and that it operates as efficiently as the maker says.

Certification by the National Sanitation Foundation

NSF International is a product testing, inspection, and certification organization based in the United States. Certified products meet or exceed the regulatory and buying requirements established by the organization, which is demonstrated by their NSF/ANSI labeling.

When it comes to obtaining an NSF International certification, the process differs from product to product. In general, a producer will need to submit product data and information before agreeing to have their product undergo laboratory testing and review.

Water Quality Association (WQA)

The Water Quality Association, like NSF International, is a third-party, independent organization that represents the interests of the residential, commercial, and industrial parts of the water and wastewater business.

Application for WQA certification is open to manufacturers who want to demonstrate that their filtered water product satisfies the specified filtration criteria.

Obtaining WQA certification signifies a manufacturer’s dedication to maintaining high professional standards while also providing improved customer service.

Features to Look For

Filter Longevity

Consider purchasing an under-sink water filtration system that uses high-quality cartridges with lengthy filter life if you want to get the most out of it. All systems will eventually require a filter replacement after a certain number of months, however the greater the interval between changes, the better the value for money.

In order to determine whether or not a manufacturer’s promises concerning filter life are accurate, it is important to read customer reviews and frequently asked questions (FAQs) to see what the general public thinks of the product.

Lead-free Faucet

If you purchase a traditional under-counter water filter, you will also need a faucet from which the filtered water will be dispensed.

The majority of systems will include a faucet as part of the initial purchase price, and the more robust and high-quality the faucet, the better. As a general rule, lead-free faucets are preferable because they prevent clean water from taking up additional impurities on its journey from the filter, such as lead and heavy metals (as the name implies).

High-Quality Components

A system with the finest quality components should be sought after throughout, from the connecting tubes and filter bodies to the faucet and the filtered water elements themselves. This will allow your system to operate at its most efficient and effective level while also ensuring that it lasts longer with minimal maintenance and upkeep.

Take a look at user reviews to find out what customers have to say about a system’s components taken together.

Thorough Instructions

Undoubtedly, one of the most significant advantages of under-sink filters is that they are simple to install without the assistance of a plumber or handyman.

In general, installation instructions for most under-sink water filters are straightforward and comprehensive, and you’ll be able to discover internet tutorials to assist you with more common tasks such as installing a faucet or changing a filter. Customers can also get live assistance from the majority of manufacturers.

Under Sink Vs Countertop Water Filters

Prior to purchasing a water filter, one of the most important questions you may be asking yourself is: “Should I purchase an under-sink or countertop water filter?”

Although there is no definitive yes or no answer to this issue, it is worthwhile to properly compare both choices in order to make the decision that is most appropriate for your needs.

Here’s what you need to know about under-sink vs countertop filtering systems:

Size & Appearance

Dimensions and Appearance

A consequence of the fact that they take up counter space is that countertop water filters are typically smaller and more compact in design. They may also be more visually pleasing in design than under-sink water filters, which are stored out of sight and so the appearance of the filter is less essential in terms of aesthetics.

Location

Under counter water filters are kept hidden away in a closet or storage place beneath the sink, so they are not constantly visible. When not in use, countertop water filters take up valuable counter space and cannot be packed away when not in use.

The majority of countertop water filters will require you to connect them to your sink faucet via a plastic tubing, which does not look particularly beautiful when displayed.

Filtered output

In addition, because the majority of under-sink and countertop water filters are regarded as point-of-use systems rather than storage tanks, the output should be equal for both.

Provided that you select a system that contains high-quality components, you will not have to wait long for filtered water to be generated.

Cost

It’s reasonable to anticipate to pay a bit more for an under-sink water filter than you would for a countertop option. This is mainly caused by the filter quality, the performance speed, and the unit size of the unit.

Installation

In contrast to undercounter water filters, which require a more involved installation process, countertop water filters are typically activated by just turning on the power. The procedure of installing an under-sink water filtering system may require the assistance of a plumber, who will have no trouble doing so if you are unsure about your ability to do so yourself.

Under Sink Filter Installation and Maintenance

The best under-sink water filter systems are simple to set up and keep in working order. You won’t need to engage a plumber unless you’re apprehensive about attempting installation on your own for whatever reason.

If you’re seeking for more information about installation before making a purchase, or if you simply want to know how it’s done, have a look at this example step-by-step process:

Installation step by step

1. Prior to beginning the installation process, you will need to switch off your cold water supply in order to prevent water from flowing through the cold water pipe that leads to your sink. To release any pressure that has built up in your sink, turn on the faucet.
2. Create a storage place for your water filters — Your water filter system should arrive partially completed, so all you’ll need to do is clear off some cabinet space and set it up in the under-sink position you’ve designated for it.
3. Disconnecting the filter system from the cold water pipe — Disconnecting the filter system from the cold water pipe and connecting one of the flexible tubes to the pipe using the two-piece fittings provided will complete the installation. Using the other end of the plastic tubing to connect to your pressure limiting valve, feed the pressure limiting valve into the inlet of your water filtration system, securing the connection in place.
4. Optional: Install the faucet — If you’re installing a traditional water filtering system, mark the area of your sink where the faucet will be installed and then drill a 13-millimeter hole in the center of the mark. Run the waterline through the faucet using the plastic tubing, and then put the other end of the tubing into the filter (Note: if you’re installing a simple water filtration system, you can skip this step).
5. Glue the tubing to the cold water pipe — If you aren’t utilizing a separate faucet for your water filtration system, you will only need to connect the other end of the filter up to the main cold water pipe once more, this time at a slightly higher point and using the same procedure as described previously. It will be marked on the filter to indicate which end will discharge clean water and which will take tap water, so double-check that you have them installed the correct way around.
6. Secure your water filter to the wall — Although it is not required, securing your water filter in place creates a more organized appearance and helps to save room. You’ll be able to easily remove your filtering elements from their wall-mounted holder anytime they need to be cleaned or replaced.
7. Reconnect your cold water supply — Once your filter has been installed, it is time to reconnect your cold water supply and check for leaks. If you discover a leak, immediately shut off the water, open your valve to alleviate pressure, and tighten your fittings and connections.
8. Fill your under-sink unit with water and let it run — Turn on your faucet and allow the water to flow for a couple of minutes to flush out your under-sink water system so that it is ready to be utilized. You will then be able to consume the purified water that has been created by the filter right away.

When to change the filter

The user handbook for your under-sink water filters will tell you exactly when to change the filters, but in general, you should anticipate them to last anywhere between 6 months and 2 years before needing to purchase a replacement filter.

If any of the following apply to you, you may need to replace your cartridges more frequently:

• Your ingoing water is particularly hard, or contains a high level of total dissolved solids
• You use your faucet more frequently than the average home or business owner

You may want to acquire a drinking water test kit to use on a monthly basis to ensure that your filters are still operating efficiently, even though manufacturers can provide recommendations on filter replacement.

How to clean and replace filters

The most straightforward method of ensuring that your under-sink water filters last longer and function properly is to clean the system and change the filters as recommended by the manufacturer.

You can find more detailed information about cleaning and sanitation in the user manual for your filter, but in general, you’ll need to disassemble the system and clean and disinfect each component individually.

All filter units have a housing that may be cleaned in warm, soapy water to remove any sediment that has accumulated over time.

When it comes time to replace your filters, the majority of under-counter water filtration systems will have a straightforward design that allows you to simply click or twist the cartridges out of the way.

Disadvantages of Under Sink Systems

An under-sink filter, like all types of water filtration systems, has a number of advantages, the most notable of which are as follows:

Single Point of Use

In the majority of cases, installing an under counter water filtration system at your kitchen sink will result in clean, pure drinking water that can be dispensed either through your ordinary faucet or, in the case of a typical filter, through the separate faucet that came with the system. Single point of use (or POU) systems are what these types of systems are referred to as.

Given that under-sink filters are intended for use only in under-sink applications, you would not be able to connect your system to a whole-house water supply line.

Installation Challenges

Most people with basic handy skills should be able to install an under-sink water filter with moderate ease, but you may prefer to leave the work to a professional if you are uncomfortable with your own abilities.

This would imply that you would have to put in an additional expense on top of your initial filter purchase price.

You may install a standard system with a faucet whether or not you employ the services of a plumber. However, the process is difficult, especially if you are not familiar with plumbing.

Water Pressure

A water pressure of between 40 and 70 PSI is normally suggested for under-sink water filters in order to get the best filter effectiveness possible.

Using a PSI pressure gauge, you can determine the pressure of the incoming water. Users who have low water pressure (less than 30 PSI) should consider purchasing a booster pump to increase the pace at which water flows through the filter.

Upfront Cost

Although an under-counter filter provides excellent value for money in the long run, the upfront cost of the filter itself may be prohibitive for certain consumers.

A typical under-sink water filter costs between $200 and $400, depending on the amount of filter complexity, the brand of water filter and the components of the individual product.

It is important to remember, however, that the price of a filter does not always reflect its quality. You may get some very decent bargains on filters that have a proven track record of providing exceptional performance.

Regular Maintenance

Under sink systems must be cleaned and maintained on a regular basis in order to ensure that they continue to function as intended.

Filtering cartridges will need to be changed on a regular basis, which implies that the additional costs associated with doing so must be factored in. It is expected that you will continue to add to your sink filtering system after you get it, so be sure you are financially prepared for this before making a purchase.

Is a kitchen sink filter right for me?

In the following situations, an under counter filtered water system is the best option for you:

1. You currently spend a significant amount of money on bottled water that is not contaminated.

As a general rule, an under-sink water filtering system is great for anyone who wishes to consume water that is purer, cleaner, and more flavorful.

If you’ve assessed the advantages and disadvantages of a sink unit in comparison to other filter models and determined that this one is the greatest fit for your needs, an undersink water filter is the right choice for you.

Frequently Asked Questions

Where can I install my filter?

Under counter filters are intended to be installed in the space or cupboard area beneath your kitchen sink. Because traditional under-sink systems are equipped with kitchen-style faucets, the kitchen is the most convenient location for installation.

Can I install and change filters myself?

Yes, the majority of people are comfortable installing their own under-sink system. Your system should come with a comprehensive instruction manual as well as all of the components you’ll need for a quick and easy installation.

The internet is a great resource for further installation assistance, as there are many videos available that walk you through the process of general under-sink filter installation that you will be able to use in the fiddlier areas of the work.

Changing your filtering cartridges is a pretty straightforward task that you should be able to complete on your own without assistance.

How do I know what’s in my water?

It is possible to learn more about what is in your water by calling your water supplier and asking to be provided with a drinking water quality report. Your water source will be identified, as well as the regulated water contaminants present in the water source, their potential health consequences when consumed, and the contamination levels in your local area in comparison to national criteria, according to this document.

Because well water is unfiltered and untreated, you will need to test your water yourself using a water testing kit in order to be assured that it does not contain any harmful chemicals.

If I already have a water softener, do I also need a filtration system?

The answer to this question is dependent on your water filtering objectives. Water softeners only remove the minerals that cause hardness in water, which include calcium and magnesium.

Installation of an under-counter drinking water filtration system is required regardless of whether or not you already use a water softener to improve the overall quality of your drinking water. This will eliminate impurities such as lead, germs, and chlorine from your water, something that your water softener will not be able to achieve.

Should I get an under-counter filtering system or an RO system?

The advantages of reverse osmosis (RO) systems cannot be overstated. For example, a RO system provides more complete contaminant removal than a conventional system. In addition to eliminating pollutants such as bacteria, RO systems have the ability to disinfect. Furthermore, a RO system can usually remove fluoride, which is something that not all under-sink systems are capable of doing. RO systems, on the other hand, are not an affordable solution for everyone. A typical RO system will cost at least $200 more than a normal under-sink system, according to industry standards. During the filtration process, RO systems generate waste water.
