How to Buy Best Under Sink Water Filter
Once you have finally decided to install under sink water filter, now it’s time to step into the market to pick the best one. But hold on! How will you choose the best one? Let’s help you a bit with it!
Here we have shared a few important points which you should consider when buying the best under sink water filters for your home: Check out below!
1. Number of Filter Stages
The best quality of sink filter system is included with at least 2-3 stages. More stages mean; you will purer and clean water. Expensive RO filters have as many as nine stages.
2. Type of Filter
When it comes to removing contaminants from water, we highly recommend the use of modern carbon filters. But if you feel that your water is already clean, there is no need to buy a pricey RO filter.
But to remove all bacteria and harmful chemicals from drinking water, an RO filter should be your top choice. If you do not like reverse osmosis or the water waste available with it, then you can choose a ceramic filter. It is cheaper, and it also neutralizes the most harmful bacteria and viruses from water. But you have to pair it with a carbon filter so that all the chemicals are removed.
3. Ease of Installation
The next most important aspect is the installation process! Some of the filter models have a complex installation process for which you need a plumber’s help. Before you purchase a filter, make sure it has all the hoses and connectors with it. Missing parts will make your whole installation process extra complex and costly.
4. Water Pressure
If you are purchasing a RO System, you should never expect to get the same water pressure as before. Hence the RO systems are slower. Their thin tubes will eventually reduce the water flow. But if you are using the system for drinking water, then this is not a big issue at all.
But some of the RO Systems, such as Home Master, use wider tubes and special filter designs. This will eventually help them to increase water pressure without compromising filtration performance. On the other side, carbon filters have a higher flow rate. They will work better if you need filtered water for higher-water-volume activities such as washing dishes.
5. Filtering Capacity
The majority of the manufacturers will list the capacity of the filter in terms of months or even years. Carbon filters will last for a maximum of 7-12 months whereas RO filters can last two years or even more.
Some of the best under sink water filters without separate faucets are also rated in the form of gallons. But if any filter is not displaying you the gallon quantity, it is hard for you to know when to replace the filter. Always check for the number of months or years of usage as recommended by the manufacturer.
6. Ease of Filter & Membrane Replacement
When you are buying replacement parts for the sink filter, look for the original one always. Always check the prices before making the final decision because some of the famous platforms also sell low-quality models.
Another important thing to check is to figure out how easily the filter can be changed. In most of the filter models, you just have to unscrew the cartridge, and remove the old filter and replace it with the new one. Hence in a few of the models, both the filter and the filter housing are one unit. In this regard, you have to replace the whole unit.
What is An Under-Sink Water Filter?
Talking about the under-sink water filter, it works as a device where it is used to filter the water coming out from the faucet from any contaminants. It performs this task through the filtration process to treat the water for safe drinking and cooking.
This is extremely important because the unhealthy and untreated water may have various harmful or undesirable things within it, namely:
- Heavy metals
- Bacteria, and
- Different contaminates
It is evident from the name that an under-sink water filter is rather installed underneath into any typical sink area. You can use it for a home in a business setting, a kitchen sink, a bathroom sink, or even a business break room sink.
Types of Under Sink Water Filters
Under sink water filters are divided into three main types, i.e. Conventional, Simple, and Reverse Osmosis. Let’s discussed all three in detail below:
- Conventional Under Sink Water Filters
These sink water filters will connect themselves with the existing cold water service to the sink and yet feed a separate faucet. They are a little bit complex to install where you will require plumber assistance. It has an improved filter life which makes it demanding in the market.

This will reduce all sorts of complications during the installation process. Plus it also removes the need to easily drill worktops and easily fit the additional filtered faucet. Simple water filtration systems need replacement regularly because they are testing the whole water to the outlet.
- Reverse Osmosis Under Sink Water Filters
Reverse Osmosis (RO) filters do work differently as compared to other filtration systems. This filter system uses the pressure all across a semi-permeable membrane to pressurize the pure water to one side of the membrane. Contaminants will stay on the other side. This will result in a huge amount of purified water stored in the faucet tank.
Why Should I Choose an Under Sink Water Filter
A few of the main reasons to choose under sink water filter are:
- Water Taste Improvements
The reason why most of the people choose under the sink water filter is the water tasting improvement. It provides clean and healthy drinking water that eliminates unpleasant odors.

There are alternatives for every user, relying on the range of contaminants you would desire to remove. You can select a widespread or extra superior system to serve your needs.
How Does Under Sink Water Filter Works?
The reason why most of the people choose to buy under sink water filter is its simple design and lack of batteries it needs. This is the main reason it is known to be an “Under-Sink Water Filter”. It is designed in such a manner where it can get fitted under the sink or even in the cupboard completely. There are filters, water tubes, or sometimes tanks from RO systems, yet nobody wants them to be out on the countertop.
An under-sink water filter will work like a buffer, which is between the faucet and water line. The waterline which is coming from the main water supply is attached to the filtration system. In this way, the water will flow directly through the filtration system and will reach your faucet. Generally, the filter is connected to the cold-water line, as this is what you will use for healthy drinking water.
Benefits of Under-sink Water Filter
Modern models of under-sink water filter are capable of reducing harmful chemicals and contaminants by using a reverse osmosis system. Old models make the use of activated carbon filter to block the contaminants. But the modern filter models have a combination of both.

An easy filter substitute is all that the system would desire from you.
- Removes Bad Odors & Weird Tastes
The majority of the under sink water filters use at least one activated carbon filter. This filter is extremely good for removing the bad smells and bad tastes from the water.
- Sediment Removal

How to Install Under Sink Water Filter
The installation process will vary according to the model you are choosing. Ensure you follow the manufacturer’s instructions before you start the installation yourself. Let’s guide you a bit about how you can install under sink water filter:
- First of all, you have to isolate the supply of water and then switch on the tap until the water has been drained.
- If the filter has a dedicated faucet, you have to fit it to the worktop by drilling a hole into the desired position. Later on, you will be inserting the stem.
- Now you have to fix the filter body into the kitchen cupboard unit.
- Next, you have to connect the existing cold water feed with the new filter. If you are using a simple under sink filter, this will connect to your existing tap. But if you are using a conventional filter, then you have to cut a tee into the main cold water feed. Just connect one side towards the existing faucet pipework and later the other side be connected with the new filter.
- Make sure tubing, connectors, and joints are fully tight.
- Close the entire tap and slowly switch the water back on.

- To prevent any sort of leakage, check the joints.
- For 10 minutes, flush the filter as the manufacturer directs it.

Some of the filters will require a replacement every six months. But some of them might survive for five years without a single one.

Under-Sink Filters vs Countertop Filters
One most asked question is to know the difference between under-sink filters & countertop filters. Let’s differentiate the two of them below:
- Appearance and Size
As we talk about personal awareness, a countertop filter is known to be a water filtration system. It sits on your counter. It either has a fill-tank or connected to the main waterline. If you are connecting it with your water pipe, it should have a faucet and filter which is built into one device. It will be mounted next to your current sink.
The reason why people like countertop filters is because they are reasonable in cost. They have an admirable filtration system. Plus they are also easy to install.
Overall, the under-sink filtration system is extra favoured than a countertop system. Countertop structures normally just have one or two filtration stages. This is ok for a few frequent family contaminants, however no longer almost as many as you will get from an under-sink system.
The other reason why I like under-sink structures greater than is something we have mentioned already.

Under Sink vs Whole House Water Filter
Is whole house filter better than under sink filter? Which one is best for your house? What is the difference between the two of them?
Before getting on to that, let’s discuss the main differences between these two types of filters below:
- Location of Installation
An under-sink water filter is installed under a sink area for usage purposes. Some of the models are also placed closer to the entry point. This is from where the water enters your house pipeline system.
Due to the bigger size, installing a whole house filter is a little complex. This is also because the water supply process is ceased during the installation of a whole house filter.
- Size and capacity
The under-sink water filter has a larger capacity. Strong and larger sink filter can survive for years. It can filter up to 50,000 gallons of water. Plus, RO under-sink filters can easily process less water (1000 – 5000 gallons) in its lifespan. It also has a higher level of pureness.
Contrary, whole house filters have the largest capacity of all the residential water filters. The time span of the whole house will last for a maximum of 6 months. Few of the whole house filter models will survive for a maximum of 10 years. They can process a million gallons of water.
- Method of filtration
Under-sink water filters are generally used for cooking and drinking purposes. They are helpful to remove the sediments, chemicals and heavy metals. The under-sink water filter is included with numerous cartridges. Possibly one cartridge has various sediment filter layers with activated carbon or carbon block filters.
Mechanical filtration is even applied over the whole-house filters. For daily uses, they have to process a wide variety of water. It does not involve strong filtration methods as they are cost-inefficient.
