Best Under Sink Water Filter Review
10. APEC 3-Stage Under Sink Water Filter
This model boasts one of the best under sink designs, brought to you by the renowned APEC. As its name suggests, it uses a 3-stage filtration process to get rid of contaminants in your water.
The filter includes a high-quality faucet made out of stainless steel. The system’s design cleans out both tap and well water, making it one of the most efficient you can find on the market.
On top of that, this unit offers one of the most straightforward installation processes we have seen in an under-sink water filter. With other models, after you purchase the system, you still need to buy separate parts for them. However, with the APEC 3-Stage filter, everything comes ready to use out of the box.
The holes in the filter are pre-drilled. So all you have to do is mount it on the wall under your sink.
9. Doulton W9330958 SuperCarb Water Filter
This unit, although simple, is as efficient as they come. It uses a cartridge as a filter to ensure the end result is water that is clear and contaminant-free to drink.
This system filters the water in four stages, with the first involving water passing through a carbon block filter. The second stage involves removing any bacteria. The third stage removes chlorine from the water, and the last phase reduces the level of heavy metals in the water.
What stood out for us is that this filter has thick tubing, which makes it more durable than other units you may find on the market. This is a good value for money as you will not need to replace your filter system now and then.
8. 3M Filtrete Water Filtration System
This system is amongst the cheapest we have seen on the market in its segment. For its price, you get a system that connects directly to your cold water line. It does not have a different faucet for filtered water. This also means that the unit will filter all the cold water passing through it.
It is easy to install, and most people can comfortably fit this unit by themselves. All it takes is just 30 minutes, and you are good to go. Typically, this system from 3M filters up to 10,000 gallons of water. You will need to change it once it filters that amount, or you can change it after six months.
We like that it filters out sand, sediment, soil, bad odor, and funny tastes. It works well despite costing very little compared to its counterparts on the market.
7. METPURE Under Sink Water Purifier
The filter system from Metpure uses four stages to clean your water, and despite this, it is still easy to install, operate, and replace. If you are looking for a low-maintenance way to safeguard the water you and your family use, then this is it.
The first stage in the filter gets rid of particles like sand, dirt, and rust. The second filter removes chlorine, carbon, and odd tastes. The third phase makes use of reverse osmosis to remove impurities such as cysts, mercury, and lead. Further, the last stage removes any impurities that may have gotten past the first three stages.
In case you incur difficulties in installing it, the company has helpfully provided video tutorials on how to properly install the system. Also, everything you could need to install the system included in the box.
6. UV Light Water Purifier
A powerful filter system from Bluonics finds its way onto our list of the best under sink water filters because of its use of UV light to filter water as opposed to regular filters. The biggest advantage a UV filter has over a regular one is that it is capable of dangerous bacteria, viruses, E Coli, algae, and fungi.
The other stages in the filter help remove chlorine, insecticides, herbicides, pesticides, odors, and a variety of compounds. The set also comes with its dedicated water faucet. Each of the filters has a label, making it easy to replace if need be.
We love the fact that it uses UV light, making it more effective against filtering, not just sand, carbon, and sediments, but bacteria, fungi, and many more. We genuinely believe that it offers great value for money.
5. Express Water Reverse Osmosis Purifier
This top-rated system from Express Water uses reverse osmosis to remove any harmful substances you may have in your water. Unlike some models that may reintroduce minerals into your water using a demineralization process, this one does not. The manufacturers understand that some people may prefer getting their minerals through other procedures.
This Express Water purifier uses five stages to clean your water. Throughout the different stages, sediment, chlorine, odor, mercury, lead, and other harmful compounds are filtered out, leaving you with completely pure water.
We love how easy it is to install this system thanks to its simple to follow the design. Each of the filters has bold coloring to ensure you know where exactly to put each. Even though it may take up more space, it does come with its faucet.
4. Woder SK Premium Class Ultra High Capacity Filtration System
This filter is the ideal one to get if you have limited space underneath your sink. You can connect this product to a hose directly, and this helps if you want to avoid any issues with plumbing.
A direct connection also means that you won’t require a separate faucet. It is selective in filtering out contaminants such as carbon, mercury, dirt, and rust, but it does leave behind compounds and minerals that are good for you so that you can enjoy pure, clean water.
We like its size such that it doesn’t take up too much space. So, this may be the right choice for those who have limited space. Also, you can use this filter for up to 3 years or once it filters 8,000 gallons of water.
3. Frizzlife Quickchange Under Sink Water Filter
Frizzlife offers a product that focuses on purifying your water from heavy metals and compounds. This unit comes with a dedicated faucet so you can specifically use the filtered water for dishes and cooking if you’d want to.
The system is easy to connect as you can have it up and running in 10 minutes. You can also make a quick change for any parts that need replacing. The two-step advance system ensures that the unit filters out harmful compounds and minerals but leaves healthy ones like potassium, calcium, magnesium, and sodium.
We like how versatile it is because it can work in other places and not just your sink. We also love how this filter manages to keep up with the water flow rate without slowing it down.
2. iSpring 6-Stage High Capacity Under Sink Filter
If you are on the market for a high capacity reverse osmosis filter system, then this is the right choice for you. It promises to remove up to 1000 contaminants from your water, including viruses, bacteria, fungi, algae, chlorine, arsenic, large particles, and other harmful compounds.
This product uses reverse osmosis to filter the water from all contaminants, including heavy metals. So, during the last stage, the filter reduces minerals in the water, restores the proper alkalinity while reintroducing healthy minerals.
The system features easy installation, complete with video guides for better demonstration.
Where most filter systems offer four stages of filtration, this one provides six. In addition to removing large particles, compounds odors, and taste, the last phase includes a demineralization filter. The use of high-quality components ensures durability in the years to come.
1. CuZn UC-200 High Capacity Under Sink Filter
The CuZn deserves a spot on our list of the best under sink water filters because it is one of the few modes that offer a 5-year pro warranty period. The unit is ideal for use with municipal water only, and not well water.
It is easy to fit because it doesn’t need an extra faucet. All you have to do is to connect it to your sink’s cold water line, and you are ready to enjoy pure, clean water. The UC-200 uses coconut shell carbon and micro-sediment membranes to filter the water, leaving only healthy minerals behind.
Our favorite feature is the five year or 50,000 gallons of water warranty. That, and the lack of a need for a secondary faucet makes it a must-buy.
Having looked at the best under sink water filters, we’d love to think that you are more informed about the options you have. We have covered basic filters to advanced ones, 3 stage filters to 6 stage filters, and simple filters to reverse osmosis ones. With a better understanding of each, we hope you will make an informed purchase.
