Best 6 Under Sink Water Filter Reviews in Details
Out of all of the products we plan to tell you about today, this one is definitely considered one of the best. We thoroughly analyzed this product and also took a look at the price and have to say that we aren’t surprised so many people are enamored by this model.
For starters, one of the biggest reasons people tend to like it is because it’s very easy to install. And even better, you do not have to get an additional faucet to install it like you have to with some other varities. Instead, you have the ability to connect this directly to the cold water line of your sink. Best of all, when you buy the filter it comes with all of the necessary components that you’ll need to install it.
Second, the filter is very efficient and lasts a long time with this system. In fact, overall you’ll be able to use this filter to produce 50,000 gallons of water and it’s estimated that this volume will take you around five years to use. So you will not have to replace this filter for at least five years, which is seriously a long time indeed.
The biggest advantage is the simple installation. The process is very easy and only requires the water filter and all of the component parts and an adjustable wrench. That’s all there is to it.
Unfortunately this is a larger filter. If you have a garbage disposal or a small cabinet under your sink, it might not fit.
Popularity is also important and this model is definitely one of the most popular choices. It utilizes a three stage process for filtration that makes it very efficient at removing contaminants from your water supply. If this filter is hooked up to your sink, you know that your water is excellent in quality.
One reason for its popularity is the simple installation process. Just to reiterate, you’ll have every component needed to install this model upon purchase and will not need to buy any additional parts.
The holes on the mounting bracket are already predrilled, so you will not need to do any drilling at all either.
Another reason why it’s popular is when the device is doing its thing, the water pressure is still really great. Many water filters do a fine job of making the water much cleaner, but the pressure usually suffers because of it. This under sink filter doesn’t have a negative effect on the water pressure whatsoever. And even though it uses three different filters, the water will still come out of your faucet very strong.
The faucet on the APEC WFS-1000 is quite good and made of the highest quality materials. In fact, it has a stainless steel faucet so it’s not some cheap piece of junk that’s going to break anytime soon.
The finish is only available in stainless steel. Some people might prefer to have the finish match other fixtures that might not necessarily be stainless steel.
You’ll really appreciate this model because it’s efficient and the water it produces is crisp, clean, and very tasty to boot. The Supercarb by Doulton takes full advantage of a cartridge filter that is very easy to remove and eliminates contaminants from your water supply.
Even better, the filter operates in stages with four of them to be exact. So each stage removes a different level of contaminants to provide very clean drinking water for your entire household.
During the first stage, the water goes through a carbon block and removes floating particles like bad odors, bad tastes, parasitic cysts, and bacteria. During the second stage, antibacterial properties come into effect and remove those types of bacterial contaminants.
The third stage uses additional carbon to remove chloramine, chlorine, and other organic compounds causing disgusting odors and tastes. The fourth stage removes heavy metals from the water.
This filtration system is very durable. The tubing is thick and strong and the housing is quite solid. So it can handle bumps and bruises and still keep on ticking.
You will also need to purchase additional parts to complete the installation. Contact your local dealer to pick them up from a store in your neighborhood or you can always buy them online.
Out of all of the recommendations we’re sharing today, we like this one best because it’s a very budget friendly choice.
And even though it’s less expensive than other options, it still gets the job done and you’ll have very clean and very crisp water after its filtered through the system.
Not only is it effective, it’s also capable of removing some of the worst contaminants around. It can get rid of herbicides, chlorine, pesticides, VOCs, and heavy metals to name a few.
You’ll truly appreciate the twist off design that they used when creating this filter. When you need to replace one of the filters, which happens about every six months or so, it’s very simple to do because you just have to twist it off and then twist the new one on its place. Really, you can have this done in a matter of minutes it’s that easy.
Another reason to love this filter is the high quality faucet. It’s an excellent faucet and when you purchase the filter you actually have the choice of picking your favorite type of finish. So, you do not have to worry about matching the faucet to your other fixtures because you can do so easily because they give you the option.
This model gives the user a filter change notification. So instead of trying to time it perfectly or guess when the filter needs to be changed, the system will provide you with the notification to tell you when it’s time to do so.
The big disadvantage is poor O-rings. The lifespan of these O-rings is typically about two or three years. But if you let the company know about the problem by contacting them through phone or email, they will send you new replacements.
We’re sharing information about this filter because it’s also budget friendly. But not only is it inexpensive, it’s also quite effective. It’s an NSF approved system that contains all needed materials and filter components so you don’t have to buy anything extra after you purchase it.
We like it because the filters last for a long time. They can filter 10,000 gallons of water, which means they may last as long as three years. Another reason to like this model is because everything needed to mount it is available during your purchase. As mentioned, you do not have to buy additional parts to get the system up and running.
The filters themselves last a very long time. Even better, it’s quick to remove and replace, like within about five minutes because you just need to twist it off and twist the new one on in its place.
The water pressure is unfortunately slow. So if you do not want reduced water pressure, you may not like this option because the pressure slows down by about 20%.
Out of every filter we’ve told you about today, this one costs the least.
But don’t be fooled into thinking that the Filtrete is anything less than stellar because it certainly gets the job done.
A big reason to consider this filter is it doesn’t require an additional faucet to drink filtered water. You can connect this system directly to the cold water line which is very convenient.
It’s also really simple to install it. Even the least handy people are capable of installing this filter without any assistance from professionals. And even better, it’s relatively quick since it only takes about 30 minutes to put it in. Best of all, the system filters about 10,000 gallons of water so you won’t need to change the it for around six months.
This unit is great because it provides excellent filtration. In fact, it removes anywhere from 97% to 100% of funky tastes, stinky odors, cysts, soil, sand, and sediment.
After thoroughly testing the unit, we learned that it’s necessary to change the filter every four months instead of every six months. While it’s certainly not a major problem, you’ll need to replace one additional filter every year which adds up over time.
The Inner Workings of Under Sink Water Filters
So, you’ve determined that you’d like to buy an under sink water filter. With this commitment in mind, it’s probably a good time to learn about how they work.
First off, it’s good to learn about the two different types of filters. There’s the simple under sink filter and the conventional under sink filter. We will take a shot at explaining the difference between the two and share the advantages and disadvantages of each as well.
They call this a simple system but the inner workings are actually quite complex. What they mean by simple is the installation process. These filters are quite easy to install but they are very complex on the inside.
Ultimately, when you install one of these filters under your sink, you will connect it to the cold water line and that will be diverted into your water filter. With this system, you aren’t required to install a separate faucet for water delivery. It comes out of your regular everyday faucet, which many people prefer. Conversely, because the filter is only connected to the cold water line, you aren’t going to get access to filtered hot water.
A few reasons to consider this system is that it’s easy to use, easy to set up, and it’s also efficient. Again, some people do not like having multiple cold water faucets. So the simplicity of the system is what attracts its many happy customers.
This system is called conventional because it makes up the original design.
The installation process means diverting water from your cold water pipe into the connector, which is typically a small plastic tube. Once the water goes through the filter, it comes out of a separate faucet that you have to install.
In your new faucet, you will only gain access to filtered water. Your regular cold and hot water faucet will remain the same, which means the water isn’t filtered. A hot water dispenser is an excellent option that you may want to consider too.
This filtration system constantly remains under pressure, so your water will continue to go through this filter and into your new cold water faucet. The big letdown of conventional under sink systems is the need for the additional faucet. You’ll either have to drill a new hole in your sink or buy a sink that already has two holes drilled in it.
The Pros of Conventional Filters
The Cons of Conventional Filters
The Major Benefits of Installing a Water Filter Under Your Sink
Under sink filters are much more effective than they were in the past. They can reduce or even eliminate many pollutants that were previously filtered only by a reverse osmosis system.
And the old versions of these systems simply used a filter made of activated carbon. This carbon blocked contaminants, but today’s modern cartridges are a combination of multiple technologies that provide fantastic results.
Then again, the new technology is great but the most important component still remains the activated carbon filter. Always remember, the more carbon in the filter, the better off the quality of your water will be.
Let’s take a look at some of the benefits that an under the sink water filter can provide. They include the following:
The Main Features to Look For
The Pros and Cons of Countertop vs. Under Sink Filters
Both types of water filters definitely have their disadvantages as well as their advantages. That’s why we’ve decided to compare the two for you today. Since their main component is activated carbon filters, we felt this was a good comparison to make.
The advantages include: countertop systems are small and they do not take up all that much space. They are also very easy to install. In fact, some people believe that they are much easier to install than their under sink counterparts.
The disadvantages include: countertop systems remove impurities at a much slower rate. So it’s going to take a lot longer for your water to come out of your faucet and into your glass. They also aren’t the most attractive filters in the world, so if you have a particular design scheme in your kitchen this device could throw off the overall look and feel.
Under Sink Systems
The advantages include: systems installed under the sink remain out of sight. And being they are under the sink, you do not have to waste any of your precious countertop space. They also filter the water at a steady rate, and this rate is typically a lot better than the filtration rate of countertop systems.
The disadvantages include: they tend to be a lot harder to install. So if you the right mechanical inclinations, you should either avoid this filter or hire an expert to install it for you. These systems are also a lot larger than countertop varities. It may be hidden underneath your sink, but it’s still going to take up a lot of your storage space under there and you might not like it.
Installation and Maintainenance
The under the sink systems are pretty straightforward to install. The following instructions should make it very easy:
Always make sure to follow any and all instructions that the manufacturer gives you. If it seems too complicated, you can always find video tutorials online. Customer service should also have no trouble providing support.
How Often Should I Change My Cartridge?
This answer is going to be different for everybody and it all depends on your filter itself. But a good rule of thumb is to prepare to change it within six months. Although there are certain models that can last for as long as five years.
Basically, just look at what the manufacturer tells you in the instruction manual and follow their guidelines. Even better, you may have bought a system that provides automatic notifications. If this is the case, remember to do what they tell you.
Changing Your Cartridges
To change your cartridges, please follow the step-by-step instructions below. They are as follows:
It’s best to change all of your cartridges at the exact same time, so follow this guideline even if one might seem cleaner than the others.
Wherever you get your water source from – whether it’s a well or a municipal water source – having a high quality water filter underneath your sink to eliminate contaminants is definitely a good idea.
