The water line from the under sink water filters passes the water through the filter on its way to the faucet and they’re very effective at removing contaminants from water, making it safe for drinking.

However, the best under sink water filter is also great for other household activities like laundry and cleaning.

However, we understand that shopping for the best under sink water filter is not the easiest of tasks and can feel like a trip through the twilight zone. Nonetheless, improving the quality of your tap water is one of the best things you can do for your health, so we’re here to ease the confusion for you with a comprehensive buying guide and review of the best under sink water filters available on the market today.

What Are Under Sink Water Filters?

As the name suggests, under-sink water filters are installed under the sink where it takes water from the cold water pipe and sends it through the water filters. Once the water is pure enough, the under sink water filter will then deliver water to the dedicated faucet for use. The entire under sink water filtration system operates on-demand, so no water goes to waste, unlike the reverse osmosis system.

However, you need to note that an under-sink water filter is a one-point system that only takes care of the water coming from the pipes under one sink exclusively. It does not filter the water supply for the entire house.

Nonetheless, an under-sink water filter dedicated faucet is independent of your standard hot and cold water, meaning you can still use it separately to get clean purified water for drinking and cooking purposes.

Should I get an Undercounter Water Filter?

Everyone can certainly benefit from cleaner water, and investing in under-sink water filters is one excellent way to ensure you and your family enjoy fresh, clean tap water. Below are a few other reasons to get under-sink water filters:

  • You only need a point-of-use water filtration system that filters only the water that comes from one sink and not the entire house.
  • You have a small unit with limited space for water filter installation. The best under sink water filter will help you achieve the highest-quality water without taking up too much space in your house.
  • You require a budget-friendly water filtration system with low-cost maintenance. The replacement filters for under sink water filters are relatively cheap enough for you to maintain the device in excellent condition for a long time.
  • You prefer to handle DIY projects on your own and don’t want to spend money hiring plumbers and electricians for your house. Fortunately, under sink water filters can easily be installed with basic plumbing skills. Each under sink water filter system will come with a manual to guide you along the way.
  • You don’t want to accumulate water bottles anymore just for drinking water. An under-sink water filter gives you instant access to fresh, clean water so you don’t have to go out and buy bottled drinking water anymore.
  • You want better-tasting water. Tap water often has a weird odor and taste due to the contaminants present in it. An under sink water filter helps remove the particles that cause a bad odor to boost the flavor of fine healthy minerals in the water.

Buying Guide: How to Pick the Best Under Sink Filtration System?

The most obvious goal an under-sink system needs to accomplish is to produce quality filtered water. However, there are also some other factors and aspects that you ought to keep in mind when shopping for a new sink filtering system. Below is a list of what to look out for:

Water Pressure

When it comes to under sink filters, water pressure is a very important factor to consider as you don’t want to be stuck with a faucet that barely has any water coming out of it after installing the filtering system. There’s simply nothing more annoying than having to wait a very long time just to fill up a glass of water.

This is why you need to ensure that the water filter you’re getting is capable of delivering good water pressure. This is an especially important point if your house already has a bad water flow rate to begin with.

Simple undersink filtration systems typically offer better water pressures than conventional ones. However, one downside to such filters is that the water spends less time in the system, so some contaminants may just slip through accidentally.

This could be a problem for those with highly contaminated water sources. However, if your water supply is already relatively clean, then the number of contaminants reaching the faucet is insignificant.

Filtering Capacity

Different filtering systems have different filtering capacities. Some filters have filter cartridges that are more efficient at removing certain categories of contaminants than others. Some models might have good overall filtering capacity but lack the materials needed to remove a specific type of contaminant you want gone.

This is why it is recommended for you to conduct a home water quality testing kit to find out what is present in your water before going out to buy a brand new filtering system. The kit shows you which contaminants are in your water source so you can quickly identify the right filtering system to help you get rid of them.

Installation and Filter Change Process

Another important factor to take into consideration is the installation & maintenance process of the water filter. Although you only need to install the system once, a complicated installation could put you at risk of damaging the entire unit. This can lead to a long and tiresome discussion with the customer support team. You might even have to pay more to get it fixed or hire a plumber just to install it for you.

Under sink filtration systems are often designed for DIY projects so that you can save your money from hiring a professional. However, if you do encounter any difficulty during installation, chances are you’ll be able to find an instructional video online from others who might help.

If you still have questions, it is recommended for you to contact their customer service team to get more valuable information regarding the installation process.

Aside from installation, maintaining the filter needs to be easy as well. Most water filter models need to have replacement filters regularly. While the process is usually easy, some models make it really difficult for you to change the filters. This can be a problem, especially if you need to change the filters once every 6 months.

Filter Cartridge Longevity

If you’re looking for under sink water filter systems, you should already know that they need new replacement filters every 6 months or so. However, several advanced models have filters that can last longer and only need to be changed once every 3 or 5 years.

The better the cartridge’s filtering capability is, the better it’s built. This means that filter cartridges that last longer are usually made with high-quality components that are very efficient at filtering the water.

However, you should also be aware that there are other factors that could play a role in how long your filters last. If your water quality is very contaminated, you will need to change the filters more frequently as they can get clogged faster.

It is worth noting that most cartridge longevity advertised is tested with municipal quality water. When in fact, municipal quality water needs to travel through old pipes that could be contaminated themselves before arriving at your home.

This means that there’s a high chance of the water being contaminated before it reaches you. So the cartridge longevity might actually be less than advertised.

Why Choose an Under-Sink Water Filters for Well Water?

Under sink water filters do not only bring you clean filtered water for drinking that’s free from harmful elements, but they can also introduce other benefits for you and your family to enjoy. Nonetheless, below is a list of advantages and disadvantages of getting an under sink filtration system.

Advantages

Better Water taste

An undersink water filter will improve the taste of your drinking water by eliminating chemicals that lead to unpleasant odor and taste.

Improved Water Quality

Obviously, this is the main benefit of water filters since this is also their main purpose. Every house requires a water filter to purify water in the most important location of the house – the kitchen.

Environmentally Friendly

Having your own water treatment system means that you don’t need to keep buying plastic water bottles for drinking. In fact, the device can help you filter tap water and fill a reusable insulated water bottle before you leave your house. This reduces the total amount of bottled water purchases and the consumption of other plastic products.

Space Saving

An undersink filter does not take up too much space in a kitchen sink as they always stay in a closed cabinet. Not only will it not take up a lot of space but it also won’t cause an eyesore like a whole house filtering system would do.

Easy Installation

Installing an undersink water filter requires minimum capabilities. You can easily learn and obtain those skills through a simple DIY video on the internet or follow the instructions provided by the manufacturer. Either way, this means you can save some extra bucks from not needing to hire a plumber.

Affordable

Like any filter, this water filter may require some additional expenses for maintenance. However, its purchase price is not very high and the replacement filters themselves are also pretty affordable.

Variety

There are a number of different sink filtration systems depending on which type of contaminants you need to remove from your water. You can choose from standard or more advanced sink systems to serve your needs.

Disadvantages

Single Outlet

Under sink systems are one-point devices that only filter clean water for one faucet in your house. Unlike other systems, this is designed to provide purified water from one single sink only. If you want to have filtered, clean water everywhere in your home, you can consider getting a whole house water filter system instead.

Separate Tap

This type of filtering device may require its own dedicated faucet to deliver clean water. For this, you can choose to install either a standard filter tap or opt for a three-way tap connected to your hot and cold water supply.

Different Types of Water Filtration Systems Under Sink

There are three main types of undersink filters: conventional filter, simple filter, and RO system.

Conventional Under-Sink Water Filter

A conventional filter is attached to your cold water supply to deliver purified water from a separate, dedicated faucet. This means you can still use both hot and cold unfiltered water from your original faucet without any problems.

Since this type of sink system requires an additional new faucet for purified water and fittings to attach to the cold water line, installing these filters can be a little tricky for some. You may even need to drill extra holes on your sink/ countertop for the faucet. On the other hand, since the purified water is separated from unfiltered water, the filter life is prolonged.

Simple Under-Sink Water Filter

Unlike the conventional system, the simple under-sink system will filter the whole cold water line that will then be dispensed through a regular faucet instead of a dedicated one. However, since this type of filter purifies more water, they do have shorter life spans and will need to be changed more often than conventional filters.

On the other hand, since the filter only requires a simple connection to the cold water line, these filters are easiest and quicker to install. In fact, installation only takes a few minutes and does not require the services of a plumber. These are a few reasons why many homeowners prefer simple filters, especially for individuals living in rented apartments and houses.

Reverse Osmosis System

A reverse osmosis (RO) system adopts the reverse osmosis process to remove contaminants from the water. The reverse osmosis systems have a filter with very small pores that only allow water to pass through. RO systems dispense pure water through a separate faucet and dispense “wastewater” that’s full of contaminants for non-drinking purposes.

Since the membrane in reverse osmosis systems is very fine, RO systems are often accompanied by several layers of pre-filters to remove larger sediments and pollutants from the water before it reaches the RO membrane. This step will promise efficiency, making the RO system one of the most effective non-electronic systems for purifying water.

However, reverse osmosis systems are also much more difficult to install. The mileage of the RO systems may also vary depending on the design of the system itself, the space available under the sink, as well as your plumbing skill.

Installing a reverse osmosis (RO) system would typically take between 30 minutes to 2 hours. If you’re unfamiliar with plumbing, it is recommended for you to call a handyman or professional plumber instead. This will then contribute to the higher total price of the reverse osmosis (RO) system compared to conventional and simple filters.

Under Counter vs. Countertop Water Filter System: Which is Better?

Conventional under sink and countertop water filters are easy to compare since they both use an activated carbon filter as their main component. Nonetheless, they each have their own set of advantages and disadvantages that you can consider when deciding.

Conventional Under Counter Systems

Pros

  1. They’re kept under closed cabinets and kept out of sight. This means they won’t interfere with your kitchen’s design.
  2. They do not take up countertop space as they’re installed in the cabinet.
  3. Good filtration rate compared to countertop water filters.

Cons

  1. Although they’re hidden under your sink, some of these filters can be larger and bulkier than countertop water filters.
  2. The water filters may also be more complicated to install.

Countertop Sink Filter Systems

Pros

  1. These water filters are smaller and won’t take up too much storage space.
  2. The water filtration systems are easier to install compared to under-sink filters.

Cons

  1. Countertop filters take longer to filter the same amount of water as their under-sink counterparts.
  2. They’re kept over counters and may ruin your design if they don’t look good.

How to Install Undercounter Water Filter

Different water filters have their own installation steps. But here are the general steps you’ll need to do to install a water filter.

  • Remove the tubing under your sink.
  • Mark the location you plan to install your new filter.
  • Make all the necessary plumbing connections.
  • Connect the filter to the sink.
  • Screw the filter in if you decide to mount it.
  • Test the new filter.

How to Maintain Under Sink Water Filters

The maintenance process will vary according to the model, but here are some common steps that you should take when replacing the filters.

  • Turn off the water supply.
  • Drain the system by opening the faucet.
  • Open the casing with a screwdriver or tool provided by the manufacturer.
  • Remove the filters.
  • Clean the casing with a damp cloth.
  • Replace the filter/filters.
  • Close the casing.
  • Turn the water back on and check for any leaks.

Frequently Asked Questions

Where’s the best place to install my undersink water filter?

As the name suggests, the best place to install the filters is under the sink. The space under your sink usually has a clear area for you to store a few kitchen items. You can move some of the items to create some space for the filter. They are packages with a kitchen-design faucet that’s suitable for installation in the kitchen.

Do I need a plumber to install and replace the filters?

No, you don’t necessarily need to call a plumber to install and replace the filters. Many filter systems are easy to install and can be done by yourself at home. The manufacturers are even ready with a team of customer support to guide you through the installation and maintenance process.

However, there’s still no harm in calling a plumber should you still feel worried about doing it yourself. You should also ask for help if you notice leaks after installing the filtration system. The goal here is to successfully install a stable filtration system that gives you clean and safe water.

Can I test the water to know what contaminants are present?

Yes, you can test the water with a testing kit to determine the contaminants present. If your water comes from a municipal or another supplier, you can also contact them for more information on the water they’re supplying you.

They will be more than happy to provide you with all the necessary information you need on the water source as well as the contaminants in the water, the health effects of each contaminant, and even the purification process they’ve used to purify the water.

All the above information is crucial to help you decide on which is the best water filter to buy for your home. A water testing kit can also give you all the information on the contaminants present in the water.

Is a water softener the same as a water filter?

No, a water softener is not the same as a filter as a water softener only removes components that cause hardness in water: magnesium and calcium. A filter system, on the other hand, removes other contaminants like bacteria, chlorine, heavy metals, chloramines, and sediments.

However, there are filtering models out there that come with water-softening features that can clean and soften your water at the same time. If you already have a softener, then you can forgo this additional feature and just get a simple system with a carbon filter.

The choice of which filter model to buy will depend on the quality of water you want to achieve. Both calcium and magnesium are important healthy minerals for the body, so that’s why some people might want to have a filter that retains these healthy minerals in the water.

Is a reverse osmosis system better than an under-counter purifying system?

No, RO systems are not necessarily better than under-counter systems. Both filtering systems have their own advantages and disadvantages. A reverse osmosis filter removes more contaminants but they’re also very expensive and produce a lot of wastewater. Whereas under-counter water purifying systems do not waste water and are more affordable.

Do I need electricity to power the filter system?

No, you do not need to connect the filters to an electricity source for them to work.

Is purified water the same as bottled water?

No, purified water is not the same as bottled water. There are different types of bottled water ranging from spring water to mineral water. Depending on the type of bottled water you get off the shelf from the store, they may contain different properties from the water you filter.

Bottled minerals and spring water have additional minerals such as calcium and magnesium whereas the home distilled water is completely mineral-free (unless you use a remineralization filter). Bottled water is filtered but usually through a less thorough filtration process and is likely to contain traces of contaminants and impurities.

Is it safe for babies to drink filtered water?

Yes, it is safe for babies to drink filtered water. In fact, it is a lot safer for babies to drink purified water than regular tap water since tap water can contain all sorts of contaminants and microorganisms that are harmful to their immune systems. The reason why parents are encouraged to boil their water before using it to make milk formula is to effectively kill or remove dangerous contaminants and pathogens in water.

Can I filter water just by boiling it?

No, you cannot filter water just by boiling it. Boiling water is a sterilization step. Since the contaminants have nowhere to go, they’re trapped in the water as it boils. While boiling water has benefits such as removing dissolved carbon dioxide gases and killing bacteria, viruses, and other harmful microorganisms, this process does not remove chemicals like chlorine and metal in your water.

How can I keep purified water?

You can keep purified water in BPA-free containers. Purified water is entirely pure and is more susceptible to leaching by absorbing chemicals and contaminants from containers. This is why it is important for you to store purified water in BPA-free plastic or glass holding tanks that do not contain anything that will make its way into your clean distilled water.

If you’re using metal, you may risk certain metal components entering into your distilled water. So, if you plan on taking your distilled water with you on the go, make sure you use BPA and BPS-free plastic or glass carafe to store the distilled water.

How long can I keep my purified water?

Just like tap water, purified water can last very long provided that you store it properly. Store-bought purified water for home appliances can last several years in an airtight container, or a year or two once opened. For purified water produced by yourself at home, you might notice your water go stale after a week or two. While the purified water is still safe to drink, it might not taste as nice.

You can tell when your purified water goes stale if you experience an unpleasant smell. It might also taste a little unusual. However, you should keep note that bad-tasting water is more likely related to its storage container than the age of the purified water.
