Best Under Sink Water Filters 2020 FAQ

What is an Under-Sink Water Filter?

An under sink water filter is a product that is stored beneath your sink. It takes water from your under sink water pipe and transfers it to a plastic tube for purification. Depending on the model you purchase, there are different stages of the purification procedure. Your water filter then uses its faucet to deliver the water back to you, once the water is pure enough for consumption.

The operations of every under sink water filter is on-demand, thus, there’s no case of water wastage. What’s more, these filters work with the reverse osmosis system, with only a single sink at a time. The filter can also be used separate from your standard kitchen faucets, still providing you with the clean filtered water you desire.

How Under Sink Water Filters Work?

The operation of an under sink water filter is very simple. It comes in two major types, namely the ‘simple under sink filter’ and the ‘conventional under sink filter’. These two units operate differently to bring the filtered water you deserve. The simple sink filter operates with your regular faucet, while the conventional filter system needs your water diverted via a connection. These two filters have different compartments where purification occurs before the water is delivered to you. What’s more, the water filters can make use of cartridge filters, carbon filtration systems and the reverse osmosis process. And depending on the combinations employed, a certain number and type of contaminants can be done away with.

Under Sink Water Filter Installation – How do I Install an Under Sink Water Filter?

Undercounter Water filters are usually easy to install. Self-installation is possible, thanks to installation-ready delivery. With most models, you will usually have the choice to opt for the installation variant with an additional tap, in a 3-way valve, or using the existing valve.

Best Under Sink Water Filters Buying Guide

When in search of under sink water filters, we all go looking for the same thing. Under sink water filters are in high demand because everybody wants to consume filtered water. To satisfy the high demand, several companies have come up with different versions of the filter system, and they all come with different features and rates

A water filter not only gives your kitchen a special touch, but it is also a purchase that benefits your health and the environment alike. However, before you opt for any water filter model you come across, you should inform yourself about the features to look out for as well as the various devices on the market. What’s more, there are some design considerations you need to be mindful of, which are vital to the functioning of your filter. Ignoring these features can cost you a lot of resources and bring about a lot of regrets.

This is why we have created the below-buying guide to further assist with the features and benefits when installing an under sink water filter in your kitchen and why buying a filter system makes sense.

Features to Look Out for When Buying an Under Sink Water Filter

– Water Pressure

The first point you will need to be considerate of is water pressure. This is a very essential point when it comes to under sink filters. Having good water pressure is vital, as it avoids you waiting too long for a single glass of water to fill. As opposed to the conventional filters, simple underwater filters tend to have better water pressure system. They also offer increased pressure and even though this is terrific, it also means that water hardly stays in your filter. The less time water spends in your filter, the more likely some contaminants are to pass through the filter unchecked. And if you live in an area with highly contaminated water, this might be an issue.

– Filtering Capacity

The second most essential feature we advise that you take a look at is the filtering capacity. The intended product you wish to purchase should be highly efficient at doing away with contaminants. Most often, this is highly dependent on the filter cartridge used. There are some filters that do more than others, which is mostly because they have a high performing cartridge.

Additionally, there are other models that work well with overall filtering but aren’t designed to identify and remove a specific type of contaminant. To make the best choice, it is best to use a home water quality testing kit, to show you which contaminants the filter can deal with.

– Ease Of Installation And Filter Change

How simple and easy is it to install the filter you want to purchase? This will go a long way to affect your final decision. The product you opt for must be simple to install and also very fast when changing filters. What’s more, the installation should be easy to help prevent any damages during the process. If your filter is tough to install, you’ll end up spending hours with customer services, or employing other skilled personnel which will demand the use of resources. The easier the installation, the more time and money you save.

– Cartridge Longevity

Many conventional water filters demand a change every six months. There are, however, some models that can be used for as long as five years without the need to change a filter. According to experts, filters that can be used longer are those that have been built better. This is because they feature cartridges made from high-quality components which make them more efficient than their conventional counterparts. Furthermore, cartridges are usually tested with municipal quality water thus, the advertised lifespan time might not be their actual lifespan. The reason is that there are different water sources, and the quality of water being filtered can affect the quality and lifespan of your filter.

Under-Sink Vs Countertop Water Filters

Under sink water filter systems make use of activated carbon filters, just like the countertop water filters. They are similar in some aspects and yet different in others. The major features of the under sink filter systems include its ability to be out of sight, and not interfere with the theme of your kitchen. Their installation under your sink also means that your countertop is left free for other things. As compared to their mates, countertop filters, these units have a high filtration rate. There are some disadvantages to this unit, like any other product on the market.

The under-sink filter also comes in sixes that may be larger than the countertop models. This will result in more storage space needed underneath your sink. Also, they tend to be tougher to install, when compared to the countertop models which don’t need any installation.

On the other hand, the countertop systems are smaller in size, and this means they won’t demand a lot of storage space. They also don’t require any installation this they’re easier to use right from your purchase. Their disadvantages, however, include that they have a slow filtration rate, which causes them to take longer to filter the same amount of water as an under-sink filter. Again, countertop filters can destroy the beauty of your kitchen design, if you don’t find a complementing colour or shape.

Who Should Buy an Under-Sink Water Filter?

Under-sink water filters are meant for everybody who wishes to benefit from cleaner water. They are ideal for people with basic plumbing skills, who don’t have a lot of space available. If you’re tired of accumulating water bottles, then the under sink filter is meant for you, too. It helps you save money and saves your health from the unhealthy features of plastics. Finally, these units are well suited for all those who simply wish to enjoy tasty water. Water that is sweeter than tap water and more favourable than well water.

Advantages and Disadvantages of Under-Sink Water Filters

One may be wondering what the advantages of having an under sink filter will offer, besides having clean water to drink. The truth is that these products offer us many more benefits than we can imagine. Despite all their positive traits, using these products also come with some demerits thus, we have compiled some advantages and disadvantages to help you make your final decision.

Advantages

– Improved taste

Using an under-sink filter helps keep the ph of your water balance, and this, in turn, affects the taste of your water. The removal of all contaminants in your water helps purify water in your kitchen thoroughly, removing odors and odd tastes that might make your drinking experience uncomfortable.

– Environmentally friendly

Most of these filter models used in homes are sustainable in design. The under sink water filter reduces your purchase of plastic bottled water and allows you to reuse your old plastic bottles within your home. This reduces the amount of plastic used around the world, reducing our waste and improving our overall quality of life.

– Storage Requirements

Because your under sink cabinet remains closed for most of the time, you won’t see your filter often. This also means that when making a purchase you won’t have to find a large space for storage, as you would do when purchasing a house filtering system.

– Easy installation

There are minimum capability requirements when it comes to the installation of an under sink water filter. Even though this doesn’t come naturally, these skills can be learned via online videos or by installation instructions and tutorials offered by manufacturers of your preferred model.

– Affordability

Every under sink filter, like many other conventional filters, will require some additional expense for its maintenance. this, however, doesn’t erase the fact that making a purchase of this product is a breeze thanks to their low cost.

– Variety

Depending on the number and kind of contaminant you want to do away with, there are varying options of this filter for all users.  You get to choose between having a conventional water filter and an advanced device that will cater to all your filtration needs.

Disadvantages

– Separate tap

One feature we don’t appreciate the under sink water filter is that to deliver clean water, it requires its own faucet. With this, you have two major options to choose from. The first is to install a three-way tap which is then connected to your cold and hot water plumbs or to install a standard filter tap.

– Single Outlet

The bad thing about these filters is that they work for only one faucet in your home. It works with a single sink, thus you will need to purchase more filtering units for other parts of your home, or even better, invest in a water filter system which can be used for your entire house.

– Installation

There are some models of under sink water systems which tends to require expert assistance when installing, such models can cause you to spend more than you bargained, and they also may cost more when it’s time for maintenance.

Different Types of Under Sink Water Filters

Though there are many models of the under sink water filter available in the market today, there are only two major types of this filter. These are the simple and conventional under sink filters. Each unit is unique in a certain way thus, they have been discussed and their benefits duly stated. Depending on your needs, you will choose one over the other.

– Simple Under Sink Filter

The first type of under sink water filters we’ll be discussing are the simple under sink filters. These units are referred to as simple and yet, their method of operation is extremely complex. The simplicity, however, is identified in how they’re installed, and not their mode of operation. All your cold water supply should be diverted through your water filter when it is being installed. The process also means that you will not require a separate faucet for the delivery of water after it’s purified as it’ll be delivered to your regular faucet instead. What’s more, connecting the filter to your cold water supply will also mean that your hot water will not be filtered.

We love the simple under sink filter because it is very user-friendly, and also because it doesn’t demand the use of many faucets.

– Conventional Under Sink System

The next and last type is the conventional under sink water filter. This unit is termed as ‘conventional’ because it encompasses how water filters were designed back in the day. For this system, installation and usage requirements differ slightly. Users need a connection to divert the water in the main cold water pipe to the system, in order for their water to be filtered efficiently.

What’s more, there is usually a faucet included with your purchase, and this should be mounted on your sink to receive water after its filtered. Also, all the water in your regular faucet, be it hot or cold will remain unfiltered, with filtered water coming in through the separate faucet only. The conventional water filer is always under pressure, but it requires the user to buy two faucet holes or drill a new sink on the countertop.

The Benefits of Under Sink Water Filters

Under sink water filters are a great accessory to have in your kitchen. They are known globally to enhance health and also deliver the best quality of water to users within the shortest possible time. We discuss some of their numerous benefits below.

– Affordability

Having this unit in your home is more economical when compared to having a whole filtration system for your home. With the under sink filter, you spend less money both for installation and regular maintenance, which can occur every five to six years depending on the model you opt for. Filters installed beneath sinks are made with high-quality materials but with cost-efficient construction methods which also enhance durability.

– Great tasting water

The second most beneficial element of the under sink water filter is its ability to deliver great ph neutral-tasting water to the user. The filtration process allows all contaminants and odours to leave your water, making it more enjoyable for you and your family. There are some models that feature a mineralization system, which helps in giving your water a delicious taste that cannot be found with other filtration systems.

– Clean water for everything.

The water you get from your filter system isn’t only meant for drinking. This is the water you can use for washing and cooking too. The level of cleanliness is adequate and safe enough for you to make use of during your culinary sessions. Water filtered with the under-sink systems are known to be free from a wide range of contaminants, and this helps prevent the spread of diseases among you and your family.

The removal of these contaminants is done via reverse osmosis and carbon filter systems, which are modern introductions to the filtration sector. What’s more, these systems also work with cartridge filters, which go a long way to dispose of all harmful chemicals present in your water.

– Durability

Under sink water filters last longer than regular water filters. Depending on the model you opt for, you can make use of the filter for many years, before the need to replace the filter candles will arise. Having such a model allows you to save money for many other tasks, which can be beneficial to both you and your family.

The durability of these water filters is in their construction and the technologies employed to keep them operational. Those that make use of the cartridge filters are known to last very long, and also requires minimal maintenance.
