Featuring the smallest, most compact, yet hardest-working filter we’ve ever seen, it gets the job done in half the time we’ve seen it take other faucet mount models to filter you water.

The beautiful dark grey color of this faucet mount filter is an excellent complement to any kind of aesthetic you may have in your kitchen. The fact that it likely won’t match your existing kitchen water faucet exactly is a distinct choice that the PUR corporation made!

Instapure Faucet Filter



  • Chrome Base with clear cap
  • No tools necessary for installation
  • Reduces bad taste and odor from chlorine

The Instapure system provides a simple way to switch between filtered and unfiltered water - not a thing that most other filters do, assuming (as they do) that once you get filtered water, you won’t want to go back. However, that isn’t always the case! There are some projects for which unfiltered water will suffice.

Being able to go back and forth between filtered and unfiltered water gives you an important advantage: You’ll be able to extend the life of your water filter by a lot! Therefore, the simple switch that the Instapure F2 Essentials Faucet Water Filter includes is a huge plus for longevity: a sign that the company behind this faucet mount water filter is caring about you, and not simply its bottom line.

This filter is certified ANSI/NSF for the complete and effective removal of chlorine from your tap water, which will not only make it a lot safer but also make it taste a lot better: definitely a win-win for you and your household.

The faucet mount filter features a sturdy chrome base which has a clear cap atop it, exposing an easy view of the filter itself so you can tell at a glance if it’s time to change ıt. The engineers who designed this product were clearly thinking of customer experience when they designed it—and it really shows.

Culligan FM-25

Culligan FM-25 Faucet Mount Filter

  • Chrome Finish
  • 0.5 gpm flow rate at 60 psi
  • Temperature Range: 40-100 degrees fahrenheit

With a brushed chrome finish which makes this mounted water filter look the most sophisticated of the bunch, the Culligan Faucet Mount Filter is efficient and inexpensive—a true bargain. This is one of the smallest faucet water filters we’ve seen; it blends into your kitchen in a way that several of the other filters will never be able to do.

It also works well with your faucet! Boasting a flow rate of 0.5 gallons per minute and 60 psi, if you use this water filter you won’t feel like your water’s coming out at merely a trickle. This filters out most of the substrates that we know are polluting the average tap water system, including atrazine — a chemical barred by few other filters.

This brand also includes a few filters in the price, which is thoughtful; you won’t have to buy another faucet filter for possibly a full year! This filter system has been vetted and tested by the NSF, and can work with pressures between 30-100 psi and temperatures between 40-100 degrees Fahrenheit.

Faucet Water Filter Buying Guide

Best Faucet Water Filter

Now that we’ve introduced the cream of the crop in faucet mount filters, let’s talk about some of the ways you can make the crucial decision: which is the best faucet filter for you?

We all want clean and tasty drinking water—it’s clear why you’d need a water filter. But how do faucet filters work? Read on as we tackle that question next.

How Do Faucet Water Filters Work?

The first thing to distinguish is the difference between purifiers and filters. The terms are often used interchangeably, but they’re actually different things. Faucet mount filter systems remove contaminants that are large enough to be caught by filters. A purifier, on the other hand, removes even things that cannot be caught by filters.

If a water filter is referring to itself as a purifier, then you’ll want to ask how (aside from filtration) it’s cleaning the water it delivers from your system. Aside from that, here’s how water filters work:

  • Sediment Removal

This is the simplest (and most important) part of a water filtration system. Once the water enters the filter system, it passes through a non-woven screen that’s been placed just under the faucet. This gets rid of any larger particles of sediment that may be in your water reserves.

  • Activated Carbon Block

After all large sediment has been removed, the water will pass through a block of extremely compressed carbon (and often, other minerals, such as zeolite). These minerals have sponge-like properties wherein they can suck chemicals out of the water.

  • Chemical Removal

Building on the previous point, the sponge-like activated carbon block will remove chemicals from the water. How many chemicals it has time to remove is directly related to how long it comes into contact with the water. When you’re evaluating water filters, you may want to keep an eye on how thick the activated carbon block is—that’ll determine how long the water is flowing through it, and, because of that, how many chemicals the block will be able to remove from your drinking water. This is what distinguishes the best water faucet filters (in terms of filtration) from others on the market. 

Next, let’s take a look at some of the benefits of faucet water filters.

What Are the Benefits of Faucet Water Filters

What Are the Benefits of Faucet Water Filters?

  • Healthier Water

There’s a basic premise that filtered water is much healthier for you. It’s true that drinking overly concentrated amounts of chemicals that may exist in your groundwater won’t be the best for your system. Particularly if you live near a chemical treatment plant or other large factory known for dumping their contaminants into water reservoirs, a faucet mount filter might be a great investment.

  • No Foul Smell or Taste

Unless there’s a chemical polluting your water which is actually extremely dangerous, a smell or taste alone is unlikely to make you sick. However, there are many benefits you can receive from merely staying hydrated, and if having a weird smell or taste associated with your water makes it more difficult for you to drink water, that could be an excellent reason to look into a water filtration system. A faucet water filter system is one of the easiest ways to get filtered drinking water straight from your faucet.

  • No Chlorine

Chlorine is put into drinking water to disinfect it. Chlorine, when dissolved in water, breaks down into hypochlorous acid, which is toxic to some microorganisms that (when in water that is eventually drunk) can cause sickness in human beings. Therefore, a little bit of chlorine is usually a good thing! However, when there’s too much chlorine, or if someone in your home is allergic to it, removing the chlorine through an activated charcoal system will likely be beneficial.

  • No Nitrates or Nitrites

Nitrates and nitrites in water come from being near fertilization companies or products. If your water system only has low levels of this, it’s unlikely to be a huge problem; however, if there are large amounts of these two chemicals in your drinking water, you may be susceptible to methemoglobinemia (or “blue baby” syndrome). If this is the case, removing the nitrates and nitrites through a good water purification system is a good idea.

  • Blocks Heavy Metals

Heavy metals in your drinking water are probably bad news because at high concentrations they tend to build up in your system — and when they’re inside you at very high concentrations, the effects can be poisonous. Heavy metals in your water can be caused by anything from environmental concerns to simple proximity issues like having your water delivered to you via lead pipes. If water tests show that you are at risk, investing in a water filter is a good step for your health.

  • Easy to Install

While many water filtration systems are billed with the option of paying for expert installation, most water filtration companies build their products with you in mind. Therefore, to install most of these systems (as well as performing simple ongoing maintenance, such as replacing filters) only requires a simple motion and a snap. Faucet water filters are generally really easy to install: just take the device out of the packaging it came in without breaking it and fit it over your faucet! Some manufacturers include adapters to fit different types of faucets.

  • Low Maintenance

Aside from cleaning a faucet water filter on its surface whenever you happen to wipe down the rest of your sink, one great thing about faucet water filters is that they don’t require any other maintenance! Simply make sure that you have some way of checking or remembering whenever your faucet filter will need a water filter change, and then you’re good to go. It’s as easy as using your faucet — but better.

  • No Plastic

One of the most cogent arguments for filtered water is that it will reduce your need for specially bottled water. If you’re producing clean, tasty water in your home, you won’t need to buy it in a store. This can save you money and also reduce the amount of plastics in your home, helping to keep your environmental impact as low as it can be.

How to Choose the Best Faucet Water Filter for You

Once you’ve made the decision to purchase a faucet water filter, you have to choose which one to buy.

We’ve tried to help by listing some of the best and most affordable faucet mount water filter options on Amazon, and we firmly believe that each of these would help you for years to come. Now we'll look at a few other things that should factor in to your faucet water filter buying decision.

  • Size

The first thing you’ll want to consider when purchasing a faucet water filter is its size. Not only will the size affect how it fits on your faucet, but it also determines how well it’s able to do its job.

The activated carbon block in faucet water filters is able to purify the water by extracting chemicals from any water which passes through it. The amount of contaminants the carbon block is able to sponge out is directly proportional to how long the water is exposed to the activated carbon block.

This means that the larger the faucet filter is, the longer the water will be in the block, which means better filtration. Therefore, in terms of size, for a faucet water filter, you’ll want to find the sweet spot between a faucet filter that’s small enough for your setup in terms of aesthetics  and big enough that the filter itself will have a good impact on the purity of your filtered water.

  • Faucet Filter Change Sensor

Some more advanced water faucet filter models come with a filter change sensor. This is basically a small light which changes color or otherwise demarcates when the faucet filter needs to be changed, taking a lot of onus off you as the filter changer. 

Faucet filter change sensors often come in one of two varieties.

  • Light Sensors: The first sensor type is often a simple LED light sensor on the faucet filter: one which often appears green at the beginning of the cycle and morphs over to red once the filter needs to be replaced. This takes a lot of guesswork out of your day! 
  • Day Counting Sensor: The Day Counting Sensor allows you a little more autonomy as to when you’d like to change your filter. The Day Counting type of sensor does precisely what it says it will: it counts the number of days which have passed since the last time you changed your filter. 
  • Filter Cartridges

Filter Cartridge - Water Filters

Replacement water filters will be an ongoing expense throughout the lifetime of your faucet mount water filter. When purchasing, check the filter prices and availability to avoid nasty surprises further down the line.

You'll also need to think about what you need to have removed from your water, as all brands are slightly different in regards filter chemicals and technology.

  • 360 degree Swivel

Depending on how your faucet water filter attaches to your faucet and how it’s made, the water filter unit may be able to pivot in a full circle around your faucet, allowing full dexterity—or not. If your faucet is already stationary, you might not have issues with this; however, if you’re used to being able to manipulate your water flow precisely, you may want to consider looking at more advanced faucet water filter models which features the requested 360 degree swivel.

  • Different Colors and Finishes

To be truthful, most faucet mount filters come in a limited color range which matches the most common faucet colors, but some models (such as the PUR on our list) have some more interesting options. To choose the best faucet water filter color for you, you’ll want to look around your kitchen and note the finishes and colors you have in your room. This will influence what finish you’ll want on your faucet filter unit.

  • Ease of Installation

One of the great ways that faucet mount filters differ from other typical kitchen appliances is that they are incredibly easy to install! Different brands may have differing levels of ease, however, so you may want to look into installation (perhaps by looking up examples on Youtube) prior to purchasing.

All of the faucet water filters in our list come with the option to request expert installation along with the product itself. This can also often help with the filter warranty: many manufacturers will void your faucet water filter's warranty if the product has been improperly installed.

  • Faucet Mount Filter Style

Best Faucet Water Filter 3

Going eco-friendly and healthy doesn’t have to be an unfashionable thing! Each of the faucet water filters we reviewed has a specific style and look. When looking at style, consider what kind of aesthetic you’re going for in your kitchen.

Do you need colors or finishes to match? Do you prefer smooth, unbuckled surfaces, or do you like it when there are a lot of moving parts? If there’s an LED light, does it matter to you that it might flash bright green or bright red? These are all things you need to think about when you’re looking for the best faucet water filter to add to your kitchen.

  • Cost and Warranty

A faucet water filter is like any home improvement: basically an investment in your home, for which you definitely need to balance cost and value. 

One thing that may help you justify looking at higher-priced faucet water filters is if the model comes with a good warranty. A warranty may feature a price-back or replacement parts guarantee if you don’t like or use the product, or if the water filter breaks within a set amount of time after you purchase it.

How to Install a Faucet Water Filter

Now that we’ve discussed reasons to buy a water filter and the different factors that might go into your decision as to which water filter to purchase, let’s end by talking a little bit about how to install the faucet water filter you just purchased! After all, the story only ends happily if you’re able to use it as soon as you are able.

1. Turn off the Water Supply

To avoid any painful or embarrassing water spouts which could arise as a direct result of your tampering with your water system, it’s a good idea to start any plumbing project (no matter how minor) by turning off your water supply. It’s a quick step which has enormous results; don’t discount the positive mental effects of being clean and dry!

2. Remove The Faucet´s Aerator

Most faucets come equipped with a built-in aerator, a tiny device at the very end of your water faucet which helps add a bit of air to your water flow (which is why water comes spurting out of most faucets instead of merely flowing quietly). You’ll need to remove this in order to attach your faucet water filter to the faucet.

3. Clean the Buildup

This part may be a little gross, but it should also be motivating in that what you’re removing from your faucet now is exactly what you’ll be removing from your water via the faucet filter you’re about to install! Get some hot water and a clean towel, and make sure to get the gunk all out of there.

4. Check if You Need an Adapter

While the manufacturers of faucet water filters have tried to make their filters as universal as possible, sometimes an adapter unit will be required. Some of the products we’ve linked above include these adapters—but it’s always a good idea to check the make of your sink and faucet against the shape of the faucet water filter, just to make sure that you won’t be frustrated by a bad fit once you have the product at home.

5. Attach the Faucet Water Filter

This part speaks for itself! Click the water filter on to your faucet.

6. Flush the Filter Cartridge

You’ll want to fully saturate the water filter for about a minute before drinking any of the water that comes out, just to make sure it works properly!

Faucet Water Filter Cleaning and Replacement

As far as ongoing maintenance goes, most makers of faucet water filters have tried to keep it as simple as possible (which is good for you!). Wipe down the water filter whenever you clean your kitchen, and make sure to remember how often to change the water filter—whether that be by a note on your calendar or an LED sensor on the device itself.
