But don't worry, there's a silver lining. With a few extra steps, you can make that tap water safe again. The tricky part? Figuring out the best way to filter it.

Should you go for a faucet-mounted filter, tuck one under the sink, or maybe a countertop version is more your style? Stick around as we dive deeper into this, sharing tips and maybe even a story or two, to help you find the best tap water filter for your home.

My Top 3 Picks for the Best Tap Water Filters

Pur Tap Water Filters

  • ANSI/NSF Certified for 71 Contaminants
  • 100-gallon Capacity
  • LED Filter  Indicator
Waterdrop FC06 Tap Water Filters

Waterdrop WD-FC-06 Tap Water Filter

  • ANSI/NSF Certified for 60 Contaminants
  • 320-gallon Capacity

The 10 Best Tap Water Filters: Lab-tested

1. Pur Advanced Faucet Filtration System (Best Filtration Power)

Filtration capacity: 100 gallons| Flow rate: 0.52 GPM | NSF Certification: Yes | Material: Plastic (Chrome Plating)

Pur Tap Water Filters

The Pur Advanced Faucet Filtration System is my tap filter of choice. It is ANSI/NSF certified to remove a whopping 71 contaminants including lead, mercury, volatile organic compounds (VOCs), as well as a range of pesticides and industrial chemicals. 

Unlike any other tap water filter in this list, the Pur also filters many of the so-called emerging compounds that the EPA keeps warning about. These include pharmaceuticals, BPA, and estrone, a form of human estrogen.  

The Pur Advanced easily installs on a standard faucet but won’t work on faucets with pull-out sprayers. This is something that stands for all tap-mounts.

It lasts for 100 gallons of water, which might seem bad in comparison with other filters.

But in my opinion, that’s the price of top-level filtration. I’d rather replace the filter more often than drink pesticides and antibiotic residues.

How about you?


  • Filters 71 contaminants
  • Tool-free installation
  • LED filter replacement indicator
  • Handy filtered/unfiltered lever switch
  • Recyclable through with the manufacturer


  • Capacity of only 100 gallons
  • Reports of decreased flow over time
  • Plastic body

Why Do I Like It?

The Pur Advanced lets me use Pur MineralClear filters that use calcium carbonate filters to add a great mineral flavor back to filtered water.

2. Waterdrop WD-FC-06 Faucet Water Filter (Runner Up)                  

Filtration capacity: 320 gallons | Flow rate: 0.5 GPM| NSF Certification: Yes| Material: Stainless Steel

Waterdrop FC06 Tap Water Filters

Another easy-to-install tap water filter, the Waterdrop WD-FC-06 uses an activated carbon filter to remove lead, chlorine, and fluoride, and improve the taste of your tap water. 

On the outside, this filter isn’t much different than Pur and Brita, but there’s one big difference. 

The Waterdrop comes with a stainless steel case, which is more resistant to everyday wear and tear. 

Like the other tap water filters in the premium range, the WD-FC-06 has a convenient swivel switch that lets you choose between filtered and unfiltered tap water.

On top of that, it has a much longer-lasting filter rated at 320 gallons.

If you have a big family or need a water filter for a small office, this is what you’re looking for.


  • Activated carbon block filter
  • Eliminates up to 60 contaminants
  • Durable steel housing
  • Capacity of 320 gallons


  • Thread seal tape needed for a good seal
  • Swiveling too often can loosen the filter

Why Do I Like It?

I love the 360-degree swivel function. It basically replaces the function of the pull-out sprayer.  

3. Brita Tap Water Filter System (Best for the Money)

Filtration capacity: 100 gallons | Flow rate: 0.5 GPM | NSF Certification: Yes | Material: Plastic

Brita Tap Water Filters

The Brita Tap Water Filter also comes with a filter change reminder and installs on standard kitchen faucets with no tools needed. Just unscrew the aerator from the faucet and attach the filter in its place. 

Its filter has a capacity of 100 gallons which can replace 700 0.5-liter plastic water bottles. 

So not only do you drink much healthier water but you get to reduce the plastic stream that often ends up in our oceans. 

This faucet water filter is NSF certified for 60 contaminants including lead and asbestos, while also removing the nasty taste of chlorine and benzene from your drinking water.

Also, you should note that Brita is the most popular tap water filter according to Amazon.


  • Reduces up to 60 contaminants
  • Removes 99% lead and asbestos
  • LED filter replacement indicator
  • Simple installation


  • Capacity of only 100 gallons
  • Doesn’t reduce chloramine
  • Adapter collar prone to failing (get a metal replacement)

Why Do I Like It?

The Brita Tap Water Filter offers a weaker filtration power than the Pur Advanced but it’s three times cheaper.

4. Culligan FM-25 Faucet Mount Filter (Best All-Rounder)

Filtration capacity: 200 gallons | Flow rate: 0.5 GPM | NSF Certification: Yes | Material: Plastic

Cullingan FM-25 Tap Water Filters

Moderately priced and with an attractive chrome-plated plastic casing, the Culligan FM-25 is easy to miss for another average overseas-made tap water filter.

However, there’s much more to it than meets the eye.

Its activated carbon block filter is efficient in removing chlorine, lead, class-I particulates, VOCs, and turbidity. (I’m looking at you, Michigan.)

The FM25 comes with 2 connectors that easily match with most standard faucets. The whole installation takes no more than a couple of minutes.

Its NSF-certified filter can process 200 gallons of water, which is enough for between 2 and 5 months.

If you ask me, it’s always better to replace filters more often, especially if you use the water only for drinking.

This way you prevent algae and bacteria from growing inside the cartridge itself.


  • NSF Certified
  • Eliminates chlorine, lead, and VOCs
  • Improves water odor and taste
  • Decent 200 gallon capacity


  • Filter housing cap tricky to remove
  • Flimsy faucet adapters
  • Not so great quality control

Why Do I Like It?

The Culligan FM-25 is a reasonably-priced tap water filtration system that can deal with most contaminants you can encounter. A safe blind buy.  

5. Waterdrop WD-FC-01 Water Faucet Filtration System (Most Affordable)

Filtration capacity: 320 gallons | Flow rate: 0.5 GPM | NSF Certification: Yes| Material: Plastic

Waterdrop WD-FC-01 Tap Water Filters

The less expensive cousin of the WD-FC-06, this tap water filter uses a 0.5-micron activated carbon fiber instead of a carbon block. 

Although less effective in retaining impurities, this filter is also NSF certified to reduce 94% chlorine, odor, and taste. 

According to the manufacturer, it also removes lead and suspended solids, such as rust and sand. 

Thanks to innovative materials, the WD-FC-01 cartridge can process 320 gallons before you need to replace it.

Unfortunately, it comes with the plastic housing so it’s probably not going to last as long as the WD-FC-06.

Still, I would ignore it considering the cheaper price tag.


  • Capacity of 320 gallons
  • Filtered / unfiltered water switch
  • Very affordable


  • Not very durable plastic
  • Feels cheap
  • Seal is a miss and match

Why Do I Like It?

With the Waterdrop WD-FC-01 around, no one can say that decent water filters are expensive anymore. Literally, everyone can get one of these.

6. iSpring DF2-CHR Faucet Water Filter (Fastest Flow Rate)

Filtration capacity: 500 gallons | Flow rate: 1.5 GPM| NSF Certification: No | Material: Stainless Steel

ispring Tap Water Filters

The iSpring DF21-CHR offers an unmatched flow rate of 1.5 gallons per minute and one of the best filtration capacities — a whopping 500 gallons! 

According to the manufacturer, this tap water filter reduces chlorine, chloramine, lead, mercury, VOCs, cysts, and many other contaminants. 

But hold on with the “Add to basket” button, chief.  

These specs are nice, but I’d like it better if the company could provide independent test results. Backed by the NSF maybe?

Price considering, this is a well-made water filter that fits on many faucet types.

A funny thing I noticed while testing this one:

In the beginning, the water had a slight aftertaste, but when I reduced the pressure and filled the next cup, it tasted much better.

It seems that the filter still needs some time to do its thing, despite the advertised flow rate.


  • Filtration capacity of 500 gallons
  • High flow rate
  • Stainless steel casing


  • Doesn't remove suspended particles
  • Not NSF tested

Why Do I Like It?

With such a filtration capacity, you can install this filter and forget about it. Till next year.

7. Engdenton Faucet Water Filter (Best for Removing Odors)

Filtration capacity: 320 gallons| Flow rate: 0.5 GPM | NSF Certification: No | Material: Stainless Steel

Engdenton Tap Water Filters

The Engdenton Faucet Water Filter uses activated carbon fiber filtration that mainly improves odor and taste, removes most of the chlorine, and retains sediments like sand, rust, and dirt.  

Unfortunately, there’s no NSF testing to certify whether it removes other contaminants. 

However, the big selling point of the Engdenton filter is the stainless steel housing that not only looks better than plastic, chrome-plated filters but is more durable and leak-proof. 

The steady flow rate will get you about 8 cups of water per minute, while the 320-gallon filtration capacity provides you about 5 months of normal use.

I have one of these installed in our family’s vacation home and so far there’s never been any chlorine smell or metallic taste in our water.


  • Durable stainless steel case
  • Long filter lifespan
  • Comes with standard adapters 


  • Leaks between adapter and faucet
  • Performance datasheet not available
  • No evidence of NSF testing

Why Do I Like It?

A durable and long-lasting water filter for people mainly concerned about bad water taste.

8. Wingsol Faucet Water Filter (Most Durable)

Filtration capacity: 200 gallons | Flow rate: 0.5 GPM | NSF Certification: No| Material: Stainless Steel

Wingsol Tap Water Filters

If you haven't had luck with plastic tap water filters, you should try this one. Built like a tank, the Wingsol is designed to survive generations of family members. 

With 200 gallons of filter capacity, the filter cartridge on this one can last up to 3 months of normal use.

But here comes the best part!

After three months, you can simply brush its surface to refresh it and put it to work again. 

So why isn’t this one the number one?

Sadly, Wingsol’s filtration isn’t that sophisticated. It removes most water sediments like dirt, rust, and sand, most microorganisms, and partially chlorine.

Although the manufacturer claims it improves taste, to me, there’s always a slight aftertaste that simply isn’t there with the Pur and other higher-end brands.


  • All-stainless steel construction is hard to beat
  • 200-gallon filter capacity
  • You can revive the filter at home


  • Not NSF Certified
  • Doesn’t eliminate suspended particles and pesticides
  • Slight aftertaste

Why Do I Like It?

If the tap water provided by your local utility is tested regularly for contaminants but you have to deal with aging supply pipes and in-home plumbing, this filter gets you covered without breaking the bank.

9. Crystal Quest Faucet Mount Water Filter System (Best Water Filter for Families)

Filtration capacity: 2000 gallons | Flow rate: 0.3 GPM | NSF Certification: No | Material: Stainless Steel

Crystal Quest Tap Water Filters
Although this filter hasn't been NSF certified by October 2021, I decided to include it in this list for its incredible 2,000-gallon cartridge capacity. 

This easily provides you with up to 12 months of quality water. 

The best thing is that the whole unit is no bigger than other upper-end filters on this list. The Crystal Quest works perfectly well even with smaller sinks full of dishes. 

Its six-stage filter reduces iron, lead, mercury, copper, nickel, chromium, cadmium, aluminum, and hydrogen sulfide, as well as eliminates microorganisms. 

However, the Crystal Quest lacks the more advanced filtration abilities of its counterparts.


  • Unmatched filtration capacity
  • Efficient 6-stage filter
  • Compact dimensions


  • Below-average flow rate
  • Slight metallic taste
  • Not NSF tested

Why Do I Like It?

This water filter is an excellent choice for people who use a lot of potable water but don’t want to fumble with the installation of an under-sink unit.

10. CuZn Bath Ball Faucet Filter (Best for Baths)

Filtration capacity: 1 year | Flow rate: N/A | NSF Certification: No | Material: Plastic

CuZn Tap Water Filters
The CuZn Bath Ball won’t get you top quality drinking water. It’s simply a quick and inexpensive solution for people who want to fill their bathtub with more enjoyable water for bathing and washing purposes. 

This bulb-shaped water filter uses the innovative KDF Filter Media Disc that doesn’t need disposable filtration cartridges. 

So what does the CuZn Bath Ball actually do?

It solves water quality issues like chlorine and heavy metals that contribute to skin irritation.

By reshaping calcium and magnesium ions so they remain soluble, it conditions the water without removing beneficial minerals. 


  • Improves the bathwater quality
  • The unit is 100% recyclable
  • One filter disc lasts up to 1 year


  • No performance data sheet provided
  • Mixed user experience
  • Tricky to keep it directly under the tap

Why Do I Like It?

CuZn is a small family company with great customer service and their product does exactly what it should do: makes baths more pleasurable.

What is a Tap or Faucet Water Filter?

What is a Tap or Faucet Water Filter

Ever wondered what a tap or faucet water filter is all about? It's your go-to gadget for cleaning up your tap water right at home. Imagine a superhero for your tap, zapping away dirt and nasties so you get clean, fresh water whenever you want it.

And the best part? 

These filters work their magic on-demand, without storing water, keeping things simple yet super effective.

Here's how it works: turn on your tap, and the water passes through the filter before it makes its way to your glass, just as easy as pouring water straight from the tap. Plus, these nifty devices come with a switch that lets you choose between filtered and tap water – talk about having the best of both worlds!

Why consider getting one? Well, despite our water going through treatment, it can still carry contaminants that you'd rather not drink. The Environmental Protection Agency (EPA) has rules for more than 90 contaminants in our drinking water, including chemicals like arsenic and lead, and even tiny baddies like bacteria. A faucet filter is your frontline defense, ensuring your water is not just clear, but clean.

Installing a faucet filter could be a game-changer for your home, keeping your water tasting great and extending the life of your filter cartridge. Plus, it's a small step towards peace of mind, knowing you're drinking water that's as pure as it can be.

How Does a Tap Water Filter Work?

Ever wondered how that little device on your faucet makes your tap water go from questionable to quenching? Let's break it down, making it super easy to understand how tap water filters, or as some might call them, faucet-mounted filters, do their magic. These gadgets are all about giving you cleaner, tastier water straight from your kitchen or bathroom tap.

Here’s the scoop: tap water filters aren't just one-trick ponies. They come packed with a multi-stage filtration process designed to catch and remove a whole bunch of unwanted stuff from your water.

How Does A Tap Water Filter Work

Stage 1

First off, we start with a layer that's all about catching the big guys – think rust, sand, and other tiny particles you'd rather not sip with your morning coffee. This is where the sediment gets stopped in its tracks, thanks to a non-woven screen.

Stage 2

Next up, we dive into the world of activated carbon filters. This stage is like a mega-magnet for chemicals. Each granule of carbon is like a tiny, porous sponge, soaking up nasties like chlorine. The beauty of this stage is in its pace – the slower the water goes through, the cleaner it gets.

Stage 3

Finally, we're tackling the heavyweights: lead, mercury, and their troublesome friends. This last stage clears out those menacing heavy metals and any lingering bad tastes or smells, leaving your water tasting like it's supposed to – clean and refreshing.

But why stop there?

If you're looking to further up your water game, consider diving into the world of water filter pitchers, replacement filters, or reverse osmosis filtration systems for an even deeper clean. Each option, from faucet filters to osmosis filtration systems, offers a unique way to ensure your drinking water is as pure as can be.

Don't forget about the little things, like changing your filter cartridge regularly, to keep your water tasting great.

Types of Tap Water Filters

Types of water filter

Deciding you want cleaner water is the easy part. Figuring out which water filter to choose? That can feel like navigating a maze. Let's simplify the options:

Faucet-Mounted Filters

Perfect for those who want a quick fix at the kitchen sink. These gadgets snap right onto your faucet, giving you the power to switch between tap and filtered water effortlessly. It's like having a mini water purification station right in your home.

Water Filter Pitchers

These are as straightforward as they come. A pitcher that holds a filter, water pours in, gets filtered, and voila – clean water. They're handy if you love your water cold (just stash it in the fridge) and they're portable, too. The only catch? You might find yourself refilling it more often than you'd like due to its size.

Reverse Osmosis Systems 

Now, this is the heavyweight of water filters. Installed under your sink, it involves pushing water through a special membrane and several filters, promising you some of the cleanest water you can get. Culligan, a big name in water treatment, says it's a thorough multistage process that leaves you with pristine water for drinking, cooking, and more. The trade-off? It's pricier and needs a bit more elbow grease to set up.

Each type has its perks and considerations, from the convenience of a faucet filter to the comprehensive cleaning power of a reverse osmosis system. Your choice depends on what fits your lifestyle, budget, and how much you're looking to dive into the world of water filtration.

Tap Water Filter Certifications

When you're eyeing a faucet filter to clean up your water, you're probably looking to ditch the bad stuff like lead, chlorine, cadmium, and mercury.

But how do you know if the filter's up to the task? 

That's where the big names in water safety come into play: the Water Quality Association (WQA), the National Sanitation Foundation (NSF), and the American National Standards Institute (ANSI). These organizations put water filters through the wringer to ensure they meet top-notch standards.

Keep an eye out for certifications like NSF/ANSI Standard 53 (for reducing health-related contaminants), NSF/ANSI Standard 42 (for improving taste and odor), NSF/ANSI 401 (for emerging contaminants), and NSF/ANSI 372 (for low lead compliance). These are your tickets to knowing a filter's got the seal of approval from those in the know.

But, here's a heads-up: while many faucet filters do a stand-up job at scrubbing away a host of chemicals and unsavory elements, there's a sneaky group they might miss - PFAs. These are tough cookies that don't break down easily and can stick around in the environment and your water. The U.S. Environmental Protection Agency (EPA) has flagged them as persistent chemicals.

For the nitty-gritty on which filters can handle what and to get into the specifics of water certifications, diving into our water filter pitcher reviews could give you the lowdown and help you make an informed choice.

What Are the Benefits of Having a Tap Water Filter?

Ever wondered why installing a tap water filter might just be one of the smartest moves for your health and the planet?

First off, tap water filters are like your personal health guard, stripping away the bad guys like heavy metals, nasty chemicals, bacteria, and even the tiniest specks of dirt. That weird taste in your tap water that makes you think twice about drinking it? A filter can handle that, making your water taste the way it should – clean and refreshing.

One super handy feature of tap water filters is their flexibility. Imagine needing some water to give your plants a drink or to clean your kitchen counter. No need to waste filtered water on that! With a simple flick of a switch, you can choose unfiltered water for tasks that don't need the purity, saving your filtered water for when it really matters.

Now, let's talk about installation – it's a breeze!

Forget about calling in a plumber and shelling out big bucks. You can set up a tap water filter yourself, no toolbox required. It's as easy as pie, and you'll feel like a DIY champ.

But here's the kicker – choosing a tap water filter is a win-win for you and Mother Earth. Every time you refill your glass from that filter, that's one less plastic bottle heading to the landfill.

Think about it: a single filter cartridge can replace up to 700 plastic water bottles. And when it's time for a new cartridge, the old ones are recyclable, making your environmental footprint even smaller.

Do You Need A Tap Water Filter?

Wondering if you need a water filter at home? It's a common question without a one-size-fits-all answer. In the U.S., the Environmental Protection Agency (EPA) ensures that public water meets certain standards under the Safe Drinking Water Act. But, even with these regulations, not every possible contaminant is covered. Plus, there's always a chance for contaminants to sneak in after the water has left the treatment plant, whether through aging pipes or other means.

Remember the situation in Flint, Michigan? That was a stark reminder of how treatments at the water plant can sometimes cause more problems, like lead getting into the water through pipes.

To get a clearer picture of what's in your water before it even reaches your tap, check out your local water supplier's Consumer Confidence Report (CCR). This report, which water suppliers are required to provide, can usually be found online. It's filled with details about your water's quality straight from the source.

But to truly know what's coming out of your tap at home, consider testing your water. Whether you opt for a professional water-quality lab or a home test kit, testing is the best way to find out what's in your water.

So, while the need for a water filter varies, staying informed about your water quality and taking steps to test it can give you peace of mind and help ensure your water is safe and clean.

After reviewing all these tap water filters, I would say that my final vote goes to the Pur Advanced Faucet Filtration System for its unrivaled filtration capabilities. 

This “art deco” styled water filter faucet attachment is ANSI/NSF certified for an impressive 71 contaminants. This includes pesticides, industrial chemicals, and pharmaceuticals that increasingly occur in tap water. 

I also appreciate its LED indicator which tells me when to replace the filter.

MineralClear cartridges are my favorites — they enrich filtered water with minerals, giving it a spring-like taste. 

If you’re looking for the best tap water filter you can buy, it has to be the Pur Advanced Faucet Filtration System.
