Installation is easy. Simply remove your faucet’s aerator and attach the filter.
Just like any other home water filter, these devices contain an activated carbon filter that removes impurities from your water, including:
- Trace amounts of pharmaceuticals
Some filters remove other contaminants, too.
Most models will allow you to choose between filtered and unfiltered water, which allows for added flexibility.

With an efficient faucet design, the Culligan FM-15A offers a quick and easy way to enjoy clean filtered water. Backed by over 2,000 reviews, this model is a customer favorite. Why does it come in at number three on our list? Because it doesn’t fit all faucets (more on that soon).

Unlike other faucet filters the Culligan FM-15A features a compact design that mounts right onto your existing faucet. No tools are required for installation, but there is a catch: it’s not compatible with all faucets.
The filter fits comfortably on 55/64-27 male aerator threading found on most standard 1 and 2 handle faucets. The filter does come with two adaptors to accommodate other faucet types, but Culligan notes that this model is not compatible with all faucet models. It’s definitely not compatible with pulldown or pullout faucets.

4. DuPont Faucet Water Filter Review
The DuPont WFFM350XCH is an advanced faucet water filter that features electric metering and a 200-gallon filtering capacity. Backed by the DuPont name, this filter is effective and reliable.

6. PUR PFM800HX Bluetooth
We always knew that PUR was going to have a number of units in our top-rated list, as they are one of the best brands on the market. This model is slightly different from the others as it comes equipped with Bluetooth. This might sound odd when you consider that it only filters water but the feature allows you to connect from the filter to your smartphone via the Bluetooth. You can then use the app to track how much water you have used and when you are going to need to replace the filter. You can even have the app automatically order your new replacement filters which does make life that little bit easier as it is easy to forget.
The PUR PFM800HX has a 3-stage filter and does a great job of filtering your water removing the following:
- 99% of Lead
- 92% of certain pesticides
- 95% of Mercury
- 70 other contaminants
If you are looking for the cleanest possible water then PUR are a safe bet and can remove more contaminants than any other brand. This will also help to remove any bad odors that you may get from your water and improve the taste thanks to the coconut shells in the filter.
The installation process was simple and took a matter of minutes to fit. Even if you aren’t confident at DIY, with the instructions provided you will be able to manage the installation without any help.
The filter will last for 100 gallons which isn’t the longest lasting filter out of the models we have reviewed but it should still last you between 2 and 3 months.
7. Aqua Elegante
If are worried that you will be changing filters all time then maybe the Aqua Elegante is the perfect model for you as it has one of the longest lasting filters on the market. It can filter an impressive 200 gallons which is double that of the PUR PFM800HX.
The filter does exactly what you would expect and removes all of the following:
The installation process is just as simple as I was expecting and will be no problem for even the most reluctant DIY’er.
Even though the filter is meant to be able to last for 200 gallons, there is no way of tracking to see when the filter requires changing and therefore you have to just make sure to change it when you believe it has filtered 200 gallons which is slightly frustrating. However, the manufacturers are so confident in their filters that they guarantee their performance for 4 months or they will give you your money back.
Overall this is a great faucet filter that looks great, does a brilliant job and the customer service you receive is by far the best out of all the brands I have ever tested.
8. PUR FM-9400B 3-Stage Horizontal Water Filtration Faucet

I had the unit fitted in a matter of minutes thanks to the clear instructions that I was expecting having installed PUR filters before.
The filter has 3 stages to ensure that all contaminants are removed and has a mineral stage to help restore some of the good minerals which can be lost in the filtering process. The PUR FM-9400B removes the following toxins and contaminants:

What to Look for in a Faucet Filter
The last thing you want is to buy a filter that is constantly leaking that needs constant attention and wasting water. Therefore, it is important to ensure that you get the right model first time.
As a general rule, like with most things you get what you pay for. If you buy a very cheap model you will most likely find that it doesn’t last very long and will require cartridge changes regularly. If it is a cheap plastic model you may also find that if you accidentally knock the filter once it is attached to your faucet it may crack the plastic thread and begin to leak.
The faucet filters are relatively inexpensive and spending an extra $10 could help you get a much more reliable model and is well worth the extra expense.
Quite often the first appearance of a model is a good indicator of the quality of the unit. If it looks as though it only cost a few cents to make covered in cheap plastic, then chances are it won’t last as long as a model built with quality in mind.
Not all faucets are the same, so it is important to make sure that you get a model that fits your taps. These units fit onto your existing faucet and therefore you want to ensure that you have a tap that will suit having a filter attached to the end of it. If it doesn’t it can look rather peculiar and may even be impractical if the there isn’t enough room to use the sink underneath the filter once it is fitted. If you find that your tap can’t have a filter attached to it for any reason then you may have to resort to using a water filter pitcher instead.
How to Install a Faucet Water Filter
If you are hopeless with DIY and worry that you could flood your house while attempting to fit a filter to your faucet, then do not panic as you don’t have to interfere with the live water supplies of your kitchen at all to fit these filters. They are simply addons to your existing faucet and do not actually control the flow of water.
You will not need the help of a professional to install a filter on your kitchen taps. All you have to do is follow these steps:
- Check to ensure that all the required parts arrived with your faucet filtration kit.
This is a stage that the majority of people will skip, but for the sake of a few seconds to double check it can save you time if you happen to be missing a part and need to stop.
- Turn off the water supply to your kitchen sink.
You can normally find the stop taps for your hot and cold-water supplies underneath your sink. This is just an extra level of protection just in case you happen to accidentally turn on the taps as you are fitting the filter.
- Remove the aerator from your existing tap.
On the end of you faucet you may have a nozzle that has a wire mesh inside. This is the aerator and it will need to be removed to allow for the filter to be attached. I would advise you wrap a cloth around your faucet and use pipe grips to loosen the aerator, then you should be able to unscrew it by hand.
- Clean off any limescale build-up.
Where you have just removed the aerator will likely have some limescale or rust where it hasn’t been cleaned before. Therefore, you need to clean the threads off so that the new filter can attach properly and avoid any chance of it leaking when being used. Using a plastic bag to soak the end of your tap in vinegar is a very effective way of removing limescale build-up.
- Assess whether you need an adapter to attach the filter.
If the thread on your existing faucet is on the outside of the connection point then you most likely won’t require an adapter, however if it is on the inside then chances are you will require an adapter.
These adapters are normally included in the filter kit. If you do require an adapter you will need to determine which size adapter you will need. Then you will normally have to ensure that the correct washer is inside of the adapter. You may need to double check the installation instructions that come with your particular model as they can vary slightly. Once the washer is fitted within the adapter you simply screw the adapter onto the end of your existing faucet to where you have just removed the aerator from.
- Attach the filtration system.
Now it is time to attach the filtration system to your kitchen faucet, where the aerator was attached or to the adapter if you needed to use one.
- Test and enjoy your filtered water
Once everything is attached, you are ready to test the system. Turn on your stop taps again and then let the faucet run for a few moments to flush out any debris that might be left over from installing the system.
Ensure that there are no leaks while it is running and if everything seems to be working as it should then feel free to try your first class of fresh, clean water.
As with any of filtration system you will be required to replace the cartridges from time to time to ensure that you are getting the purest water possible.
When you buy your faucet filter make note of how often they recommend to change the cartridges in the user manual as different models can vary slightly. The cheaper filters can need replacing monthly, but there are some filters that can last up to a year. Some models come with an electronic filter life indicator which lets you know when you need to change the filter. This is something that you may want to take into consideration when deciding what model to buy.
The cost of the replacement cartridges can vary depending on what model you have, but they are generally inexpensive when you consider how much clean water you get from each cartridge. On average a replacement filter will cost about $10, I would recommend that you buy a pack of 4 when you buy the filter unit so that you don’t need to worry about planning ahead for when it will need replacing and you will have one ready to go.
What are the Different Types of Filter?
A question that we quite commonly get asked is “are there many different types of faucet filter and what are the differences?”
In terms of the actual filters, most of the models filter the water in roughly the same way and use layers of filtering materials to purify the water. The materials used within the filters may vary slightly and the more expensive filters will use a number of these materials in a combination of layers to achieve the purest water they can.
There are slight differences between each model and how they actually work. Some models have the option to be able to switch between filtered water and unfiltered. This is because, if you are washing dishes then you may choose to use unfiltered water in an attempt to extend the life of your cartridge. These models tend to be a little bit more expensive but they are better at filtering your water as they are not restricted in size quite as much as the in-line models are.
As you may guess from their name, the direct flow filters fit directly onto the end of your faucet and you cannot switch between filtered and unfiltered water. These models tend to be slightly cheaper and not as good at filtering the water as they try to keep them as small as possible to minimize the amount of room taken up in your sink.
The only downside to the 2-way flow models is that they tend to weigh a bit more which can put a little bit of pressure on your faucet which you will need to consider when deciding what model to buy.
