Best Faucet Water Filter Reviews
1. Waterdrop Faucet Filter – Best Tap Water Filter
In our opinion, the best faucet water filter is the Waterdrop Filtration System. It is one of the simplest and easiest ways to ensure your water is safe to drink. All you have to do is screw it on to the end of a faucet in your kitchen or bathroom, and its efficient carbon filter does the rest.
This product uses an Activated Carbon Filter (ACF) to clear your water of contaminants. It removes lead, chlorine, fluoride, and improves the taste of your water.
While the Filter design is nothing new, it is a step up in quality compared with competitors. It is made to last from sturdy materials that are resistant to damage and everyday wear and tear. Plus, it has a long-lasting filter that won’t need continuous replacement.
Also, compared with competitors, the Waterdrop Faucet Filter has a sleek look. It delivers water that is clean, crisp, and refreshing. Its filter is rated for 320 gallons, which is about three months of use for an average user. However, some report that their filter lasted as long as six months before it needed replacing.
As for design, the entire unit is made up of three main components: the filter cartridge, faucet adapter, and water switch. The faucet adapter screws onto most typical faucet housings, and the Faucet Filter comes with adapter pieces for 15/16” and 13/16” faucets.
Once installed, the Waterdrop Faucet Filter provides an outlet for tap water and another outlet for filtered water. With the water running, simply turn the water switch, and filtered water will begin to flow from the outlet.
Overall, this product comes highly recommended. Waterdrop has taken a simple and effective design and perfected it. It’s super-easy to install, is built for durability, and filters water efficiently. Plus, it has an economical price.
2. PUR Advanced Faucet Filter
As one of the leading faucet water filters on the market, the PUR Advanced Faucet Filter is a standout among a growing list of budget-friendly water filters for your faucet.
Although some have panned this filter for its unusually slow flow, we found that it adequately filtered our water supply at a reasonable speed even after several weeks of heavy use.
Featuring patented PUR technology, this water filter for your faucet easily screws onto the end of your sink faucet and a bright LED indicator lets you know when it is properly installed.
Once it is ready to go, the PUR Advanced water filter is good for up to 100 gallons of water (or roughly three months of water use) before it needs to be replaced.
Regarding water taste and filter quality, we found that the PUR Advanced faucet filter was comparable to that of the PUR pitcher. Although the taste may not be as subtle as the water from the pitcher, you can tell that the multi-stage filtration process is the same in both.
In our view, the taste from PUR water filters is superior to Brita and ZeroWater.
Overall, the PUR Advanced faucet filter provides excellent water filtration for lead, mercury, chlorine, and other dangerous additives without the hassle of having to fill a pitcher. If you do not want to settle for lousy filter quality, we suggest giving the PUR Advanced Faucet Filter a try.

3. Culligan FM-25 Filter Mount
Finished with decadent chrome, the Culligan FM-25 Filter Mount for your faucet provides superior water filtration quality and a luxury design at an affordable price. With this faucet filter, you get the best of both worlds regarding aesthetics and performance.
This is because the Culligan FM-25 boasts a minimalist design while also providing one of the highest water flow rates in the business.
From the minute we took this water filter out of the box, we noticed that it was considerably smaller and lighter than comparable Brita or PUR water filters. Weighing less than one pound, the Culligan FM-25 can be easily screwed on to any faucet with only one hand.
Unfortunately, however, this Culligan model does not fit on drop-down faucets.
Unlike some other water filter brands, the Culligan FM-25 comes with several adapters in the box which make it compatible with all standard (e.g. non-drop down) sink nozzles . Using “Carbon Block” technology, the FM-25 can filter out virtually all contaminants for up to 200 gallons.
Better yet, all water filters are NSF-certified, so you know they can be trusted to not do any harm to your water.
Ultimately, there is a lot to love about the Culligan FM-25 water filter. Unless you have a drop-down faucet, there is hardly any reason we could imagine not to consider investing in this sleek and efficient water filter. Plus, its water flow rate can reach as high as 0.5 GPM at 60 psi, which isn’t bad if you ask us.
- It features a speedy flow rate of up to 0.5 GPM
- FM-25 filters can be used for up to 200 gallons of water
- No tools are required to set up the FM-25
- A simple diverter can be switched to go from advanced to regular filtration
- NSF-certified for additional peace of mind
- It provides great-tasting drinking water
- This model is not compatible with drop down faucet heads
Overall, we think that the Culligan FM-25 water filter provides exceptional value for those who want to get the most out of their money while also maintaining an elegant aesthetic in their kitchen.
With a high flow rate and chrome finish, this is an outstanding faucet water filter for those with standard-size faucet heads.
4. Brita Tap Water Filter
The Brita Tap Water Filter is a formidable tap water filter solution for households that need clean, pure tap water without breaking the bank. Unlike their world-famous filter pitchers, Brita’s faucet water filter comes with three spray options that vary the flow rate and filtration level.
This way, users have more freedom to decide how fast they want their water to pour.
Unfortunately, this water filter only fits standard faucets. This means fancier faucets in a drop-down style are not compatible with this device. However, most households have standard fixtures which this water filter can easily attach to without any issues.
Even though we have layperson plumbing skills, it only took us about five minutes to fully install this filter on our faucet — pretty easy.
When it comes to home water filtration, there is no water filter brand that is more trusted than Brita. After all, they are the brand that made the water pitcher craze so popular in recent years. However, one should not assume that because they were the first that they are the best. While this brand certainly offers great value, other brands are starting to give it a run for its money.
Overall, there are few complaints we can lodge at the Brita faucet water filter and many compliments. For instance, it is a breeze to install and can successfully weed out 99% of all pollutants and pathogens in drinking water.
- Bright LED indicators let you know when to change the filter
- Users can switch between three different spray options for different water flow rates

Although, like most, the Brita Faucet filter is made of plastic and can sometimes slow down after extended use, you can never go wrong by investing in Brita’s excellent filtration technology.
5. Wingsol Faucet Water Filter
The Wingsol Faucet Water Filter is one of the best stainless-steel tap water filters you can buy. Plus, its sturdy crack-proof construction means you can use it for generations without ever having to worry about replacing it with something newer.
Although this filter device is a little bit clunkier than some other models, you cannot go wrong by upgrading from plastic to steel. Unlike other filter brands, the Wingsol Faucet water filter is one of the best in the business from a durability and longevity perspective.
Based on our few months of use with this device, we were extremely satisfied. The Wingsol water filtration system removes most dirt, sand, rust, chlorine, chrome, mercury, and lead from drinking water.
However, the downside is that there is a bit of an aftertaste to the filtered water that is not present with Brita and other water filter brands.
- The stainless steel construction is sturdy and well-designed
- The price point is attractive for budget-minded shoppers
- The filter only needs to be replaced after every 200 gallons

Faucet Water Filter Buyer’s Guide
How Does a Faucet Water Filter Work?
Faucet water filters are designed to bolt onto your kitchen faucet. Rather than dispensing water through your faucet’s spout, it is routed through the attached filter where the water filtration process will occur.
Here is the basic process in water filtration:
Sediment removal is step one in the water filtration process. This step occurs with a non-woven screen that is wrapped around the filter cartridge. The screen catches both large and small particles, including rust, dirt, debris, and sand.
Activated Carbon Block Removes Chemicals
After the sediment is removed from the water, it moves through an activated carbon block within the filter. Each carbon granule has millions of little pores that act as a sponge and remove chemicals. This process is called adsorption. The slower the water flows through the carbon block, the more contact time it has with water, and the more chemicals are removed.
Removes any additional Chemicals
The final step in the faucet filter is removing chemical contamination in the water. While the carbon block is great at removing some contaminants such as chlorine, sometimes it misses other ones like magnesium and calcium. The final chemical removal process removes other contaminants like lead, nitrates, and mercury.
As a final plus, this process improves taste and eliminates any odors from the water.
Water Filtration Quality
NSF International is a public health and safety organization that works to improve global human health. They accomplish this goal by testing and certifying products, including water filtration systems.
NSF certifies drinking water filters to standards applicable to each type of treatment option. For example, you may notice NSF/ANSI 53 or NSF/ANSI 42, which refer to the standard to which the filter has been certified.
NSF certified means that an independent, third-party organization has tested the water filter and found it to meet certain guidelines. This gives consumers some peace of mind, knowing that their water filter product has been evaluated by a third-party.
For example, water filters meeting NSF/ANSI 42 are certified to reduce impurities such as chlorine and unpleasant tastes or odors. NSF/ANSI 53 are certified to reduce one or more contaminants with a known health effect, such as lead.
Benefits of Faucet Water Filters
There are many benefits of faucet water filters. Take a look at some of them:
Provides Clean, Safe Water
Perhaps the most important benefit is cleaner, safer water. A water filter’s main purpose is to remove minerals and contaminants in your water in order to make it clean and safe to drink from your faucet. By using a water filter, you are removing harmful chemicals, including lead and other bacteria that could potentially make you or a family member sick from drinking water.
While there is the initial cost of a faucet water filter (although they are affordable!), they will ultimately save you money if you have been buying water from the store. You no longer will need to buy bottles of plastic water; simply refill a water bottle from the faucet’s water whenever you want.
Having a faucet water filter means having fresh, clean water whenever you like. No longer needing to go to the grocery store to buy drinking water is a plus! Faucet filters are more convenient than other water filtration systems, too. For example, pitcher filters are limited by the amount of water a pitcher can hold. Filter faucets also take up less space than countertop water filters and under-sink water filters.
Reduces Plastic Waste
Many people drink bottled water if they don’t like the taste of tap water. Let’s face it: with over 500 billion plastic water bottles sold in the United States each year, there’s a lot of waste that won’t be recycled. Switching from buying bottled water to using a home water filter system on your faucet is not only economical, it reduces plastic waste.
Easy to Install
Water filter faucet attachments are simple to install. In fact, they can usually be installed in under five minutes without any difficulty. You can rightly consider the installation as easy when wanting to attach a water filter to your kitchen faucet for more pure drinking water.
Frequently Asked Questions
When deciding if a faucet water filter is a good choice for you and your household, you need to know what exactly water filters remove.
Tap water filters remove chlorine, produce better tasting water, and eliminate odors. Filters also remove types of sediment, including rust, sand, and dirt. Finally, they remove any harmful organic compounds, bacteria, and viruses.
When looking for a faucet water filter, you want one where the contaminants are reduced or even better, eliminated completely from your water. Reputable companies will publish lab test results to back up their claims, so it’s important to read these.
You should also pay attention to the size of the water filter. While faucet water filters are generally compact, some are larger than others. You don’t want it to occupy too much space in your sink area.
You should also research the water filter life, which is measured in gallons. The longer the water filter lasts, the less often you will need to change the cartridge.
Also, make sure that you’re going to be able to buy replacement cartridges for the water filter.
No. You should always check with the manufacturer of your faucet before buying an attachment. Filters do fit on most faucets, but not all of them are compatible with every faucet.
As I mentioned, installing a faucet water filter is a breeze. Each one comes with detailed instructions, so following these carefully will ensure that your water filter is installed correctly on your faucet.
The basic steps include removing the aerator from your faucet, cleaning off any buildup, checking to see if you need an adapter, and if so, attach it, attaching the filter, and flush the cartridge.
The only maintenance necessary for a faucet water filter is changing the filter cartridge on a regular basis. Manufacturers indicate the lifespan of the filter, so check your product’s specifications for replacement time interval.
Typically, each water filter cartridge has a 100 to 300 gallon capacity.
It is easy to know when to change the filter if the water filter includes a filter change sensor. The light will indicate that it’s time for a replacement.
Believe it or not, there is a lot that goes into purchasing a faucet water filter. After several years of trying out new devices, we still find ourselves going back to different faucet water filter units to see which we love most.
With so many top water filter brands entering the market, including Culligan, PUR, Brita, ZeroWater, and others, it can be a daunting task to find the best faucet water filter for you.
To make your life a little easier, we put together a short list of takeaways and suggestions for finding the best faucet water filter if you are short on time. Below, find our top pointers and tips that must be understood before you check out the faucet water filter choices:
