Overall Best – Brita On Tap Complete Water Faucet Filtration

View On Amazon

The Brita On Tap water faucet filtration system is our top pick for the best water faucet filter. It’s the most affordable faucet water filter in the market now and comes with tons of features.

First, the filter comes in chrome and white colors. Thus, it’s suitable for most kitchen and bathrooms irrespective of the interior décor. Both colors look great although we love the white color the more since it suits our test area. Aside from that, it comes with 2 filters.

The filters remove up to 99.99% of water contaminants such as lead, chlorine, dissolved asbestos, etc. It doesn’t remove water hardness since it’s not a water softener. If you want to remove water hardness, read our review of the best water softeners.

The filter has a lifespan of 100 gallons. Brita equipped the unit with a light indicator that shows green when the filter is good and red when it needs to be changed.

View Features and Pros/Cons

Features We Love

  • 100-gallon filter lifespan.
  • Light indicator for filter change.
  • Two colors to choose from.
  • Easy to install and replace the filter.


  • It is available in white and chrome colored finishes to match your interior colors.
  • Installation is easy and all you’ll need for installation is included in the package.
  • The light indicator is helpful as it indicates when to change the filters.
  • You save costs as one filter can filter up to 100 gallons of water which is akin to 750 water bottles (16 oz.).


  • 100-gallon filter lifespan is quite low.

If you’ve been spending heavily on buying water bottles, the Brita On Tap water filter will help you cut costs. The 100-gallon filter can save you from buying about 750 standard-sized 16 oz. water bottles. That’s a significant cut for a large household.

Installing the filter onto a faucet is easy and simple. It’s compatible with standard faucets, but incompatible with the pull-out and spray style faucets. This is one of the chief reasons why we indulge you to take note of the compatibility of the unit before you buy.

The unit comes with all that you’ll need for a hassle-free installation and you don’t need a professional to help you.

Budget Pick Waterdrop Water Faucet Filtration System

View On Amazon

If you’re low on budget, you should get the Waterdrop faucet water filter. Its price is the same as the Culligan Fauct Water Filter which is the next best faucet water filter we’re reviewing.

The Waterdrop faucet water filter is made to last longer than its counterparts. Despite being a budget unit, it looks pretty solid and will surely last a long time on your faucets. The unit is only available in white color unlike our best value and overall best picks. The white finishing does look nice, however, homeowners who prefer chrome finished fittings on their faucets will not look its way.

The unit comes with a high absorptive filter made from CF material. We were thrilled to find out that each filter has a 320-gallon lifespan. This should save you the cost of about 2000 standard 16 oz. water bottles.

View Features and Pros/Cons

Features We Love

  • 320-gallon filter lifespan.
  • White finishing.
  • Easy to install.
  • Steady 0.5 GPM flow rate.


  • Fits standard faucets only.
  • The unit has a steady flow rate of 0.5 GPM.
  • Installing the unit is a breeze.
  • You save the cost of 2000 water bottles when you install the product.


  • Lacks a light indicator.

As you’d expect, the filters are easy to change and can be bought easily. The water switch lever is as smooth as the one on the Brita On Tap faucet water filter. We love the swift and smooth switching from filtered to normal water.

Internally, you’ll find a filter with 3 stages; one intercepts the larger particles. The other two take care of both the odor and smaller particles in the water.

If you have the spray style, pull out, and hand held water faucets in your home, don’t buy the unit. It is only compatible with the standard faucets.

For installation, the unit come equipped with all that you’ll need including six different faucet adapters. The installation process itself requires no prior knowledge nor does it require a professional to handle it.

A quick look at the installation guide clearly shows the installation process which takes a few minutes. The flow rate remains 0.5 GPM for this unit, meaning your water will flow just fine without any unnecessary slowdown.

We only dislike the absence of a light indicator on this unit.

Best Value Culligan FM-100-C Faucet Mount Water Filter

View On Amazon

We could have easily picked any of the faucet water filters with a 320-gallon filter lifespan as the most valuable faucet water filter but we didn’t because they were a tad more expensive than the Culligan FM-100 faucet filter, yet lacked a light indicator for the filter.

Undoubtedly, the Culligan FM faucet filter offers more value than any of the faucet filters on our list. The fact that it’s inexpensive makes it a faucet water filter worth installing.

Culligan offers the Culligan FM100 faucet water filter in two color options to better suit the interior décor of your kitchen and bath. The Chrome finish looks more beautiful on this model than the white finish.

View Features and Pros/Cons

Features We Love

  • 200-gallon filter lifespan.
  • Available in chrome and white finishes.
  • Inexpensive
  • Easy to install.
  • Sports a light indicator.
  • 5 GPM water flow rate.


  • The unit is available in two color finishes.
  • It’s very easy to install and comes with all the fittings needed for installation.
  • The filter has a 200 gallon lifespan.
  • Steady water flow rate of 0.5 GPM.
  • The light indicator flashes red when it’s time to change the filters, thus saving you the stress of marking calendars.


  • None

The filter on this unit has a 200-gallon lifespan. This is lesser than the 320-gallon lifespan on some of the units in this review. However, the high cost of those units and the absence of a light indicator are drawbacks for us.

Contaminants like lead, chlorine, sediments, etc. are effectively removed by the filter on this Culligan FM 100 faucet filter. We love the light indicator on this unit. It’s set to flash red whenever the filter needs to be changed.

The unit is compatible and easy to install on a variety of water filters but it doesn’t work with the pull-out and the hand-held water faucet styles. Installation is easy and requires no professional skills nor tools for installation.

As you’d expect, the unit comes with all the necessary fittings required for attaching it to your faucet. The water flow rate remains steady at 0.5 GPM.

DuPont Water Filtration Filter

View On Amazon

The DuPont filter is the next filter we’re reviewing. It’s one faucet water filter with a difference – not every of its kind has an LCD screen. One reviewer called it a digital water faucet.

It’ll interest you to know that the LCD screen doesn’t do much besides displaying the number of gallons the unit has filtered. The DuPont faucet water filter comes has a 200-gallon lifespan.

The LCD screen is easy to read in daylight from a small distance. It’s battery powered and the battery lasts long. The small LCD screen is not back-lit, so you’d have to turn on the lights in the room to view the gallon count at night.

View Features and Pros/Cons

Features We Love

  • LCD displaying filtered gallons.
  • 200-gallon filter capacity.
  • Filters perfectly well.
  • It is easy to install.


  • The unit is compatible with a wide range of standard faucets.
  • Installing it is as simple as ABC.
  • The number of gallons filtered by the unit is displayed via an LCD screen.
  • An effective filter that removes a lot of contaminants giving you clean safe drinking water.


  • None.

The filter performance is as expected. It removes water contaminants such as cysts, asbestos, mercury, lead, odor, taste, etc. leaving you with 99.99% clean drinking water.

Unfortunately, the DuPont Faucet isn’t compatible with spray style pull-down faucets. This is to say that it works with only the standard faucets.

The unit is very easy to install and it comes with all you’ll need for the installation. However, you may need to buy a faucet adapter if the adapters included in this unit don’t match your faucet. The chances of this being the case are, however, quite slim.

DuPont offers the unit in three different colors. However, we reviewed only the white model which was by far the cheapest of the trio. The other available colors include chrome and brushed nickel.

JETERY Faucet Water Filter

View On Amazon

The Jetery faucet water filter is the last faucet water filter on this review list. It has no special features save for the presence of the state of the art 320-gallon water filter. This is a huge selling point for the product.

In addition to its 320-gallon filter lifespan, the unit looks premium yet is affordable. It costs only a tad higher than Brita On Tap faucet water filter which we reviewed earlier.

The filters which are BPA free and made from food grade materials remove contaminants such as unpleasant color, chlorine, bacteria as well as odor, to mention few.

With the Jetery faucet water filter installed in your home, you’ll save money on up to 2400 water bottles with 17 oz. capacity. The benefit is huge – a large household will attest to this.

In terms of compatibility, the unit is only designed to be compatible with standard faucets, but not pull out or spray style faucets. Lastly, the unit lacks a light indicator which notifies you when to change filters. Therefore, you should mark your calendar as soon as you install the unit or replace a filter.

As expected, the flow rate remains at 0.5 GPM.

What You Should Know When Shopping For The Best Faucet Water Filter

We handpicked and reviewed the seven faucet water filters above based on some factors. In this part of the article, we’ve listed those things worth considering before you take out your credit card from your card holder.

In no particular order, we have the following…

Is it compatible with your current water faucet?

It is important to know if the faucet will be compatible with the faucet you already installed in your sink at home. Some of the faucet water filters in the market are marked “compatible with standard faucets”. In addition to that, the faucet water filter producers include descriptions of the faucets that are compatible with their products.

What type of filter do you want?

Faucet water filters come in one or two of the following types;

  1. The Carbon Filter: The carbon filter is often used as a pre-filter to remove sediments from the water before the water is then passed reaches the UV or reverse osmosis filters. Carbon filters are highly effective in removing water contaminants to a large extent.
  2. Reverse Osmosis Filters: Reverse osmosis filters are designed to filter water more than carbon filters. Water filter systems that have a reverse osmosis filter sometimes make use of a carbon filter to remove sediments from the water first before the water is filtered again by reverse osmosis.
  3. UV filters: Ultra-violet light technology is used to filter the water in this case. The filters use light bulbs powered by either electricity or battery to remove contaminants from the water. Again, carbon pre-filters need to be installed to remove sediments before the water then passes through the UV filters. It makes the end result of the water odorless and 99.99% free from water contaminants.


This is another important factor to consider when shopping for faucet water filters. A faucet filter is meant to be used for a long time. Hence, it is important to take note of the product’s warranty period to get an estimate of how long you’ll be using it.

In addition to that, you should check out customer reviews about the product. If more than five persons complain about a flaw, think twice before buying it.


What material is the faucet water filter made from? Don’t be surprised if you find plastic models. However, we strongly advise against buying it as it will age quickly.

Opt for the stainless steel models as they have a longer lifespan than the plastic models.

What’s The Size Of Your Faucet?

We implore you to take note of the size of the faucet in your home and get a faucet filter that is proportional in size to it. A small faucet with a big faucet water will look out of place and can significantly ruin the aesthetics of your kitchen or bathrooms.

Filter Change Sensors

Newer faucet water filter models are equipped with a light indicator that notifies you of when to change the filter in the unit. You should consider buying a model with this feature although it’s not a must-have feature.

This feature ensures you won’t have to mark your calendar with each filter change. Apart from the light indicators, some models come with a digital screen that displays how many gallons of water the unit has filtered.

Longevity of filters

Opt for models with long lasting filters. They are undeniably a good way to save money and filter your water at the same time. Many of the filters must be replaced after 100 gallons of water and others, after 320 gallons. Choose wisely.

Installation Difficulty

From our research, we found out that most of the faucet water filters available on the market, installation doesn’t require any tools. Therefore, if you come across any faucet water filter that requires anything other than a plier for installation, ditch it.

Aside from installation difficulty, finding a replacement filter for the unit shouldn’t be a herculean task.


Consider the color scheme/interior décor of the room where your faucet is. If your bathroom is white, go with stainless steel or a white faucet filter. Opt for colors that complement the environment, not colors that stand out glaringly.


Faucet water filters come in two different styles, one allows the filters to rotate horizontally while the other allows the filter to rotate vertically. This helps you to move the filters out of the way when you need the sink to do the dishes.

Flow Rate

Standard water flow rate for faucet water filters is circa 0.5 GPM. Opt for faucet water filters with the same flow rate.

Installing A Faucet Water Filter: Our How-To Guide

In the course of writing this review, we made mention of the fact that anyone can easily install their faucet water filter. Here’s a step by step process on how to install a faucet water filter. For this exercise, you’ll need the following;

  • The water filter you want to install, a pipe wrench, and Teflon tape. A quick look at your product manual will show all you need. But sincerely speaking, these three things are all you need.


  1. Remove the new faucet water filter from its packaging and set it on a table.
  2. Place your filter inside the unit. On some models, the filter will be placed inside the unit before they ship it to you.
  3. Remove the aerator from your faucet. Wipe off the washer on the faucet after you remove the aerator.
  4. Check which threading your faucet has. It can be external or internal. Use the adapters to set attach your faucet water filter to your faucet. Most units come with up to three adapters. Purchase extra adapters if need be.
  5. After attaching the faucet filter to your faucet, tighten the joint and then switch on the faucet. Your filter is ready for use.

Do This Before Using Your Faucet Water Filter

As soon as you install your faucet water filter, don’t start drinking directly from it. Turn it on and allow water to run from it for about five minutes. This will prep the unit and wash off any unnecessary things from inside it.

Final Words

Having read through our review of the best faucet water filter systems above, we’d like to suggest a few things. First, get a unit that is suitable for your household. Secondly, buy and keep replacement filters at home in case you need to change filters quickly.

Drink. Wash. Cook. Do anything you want, you’ve got clean water.
