Of course, that is not the only important aspect here, right?

What is interesting about the filter is the front display meter. It will advise when is time to change the filter itself.

Brita Faucet Filter

This faucet mount water filter is, maybe, one of the strongest competitors for other manufacturers.

Indeed, the name is well know around the industry but the quality of the faucet models could be a different story.

Aside from the classy design, this tab filtration system offers other interesting features that possibly other faucet filters don’t have.

Not sure yet if this is the right filter to install? We strongly suggest you read our review.

Brita Faucet Filter review


  • It is lightweight and easy to maintain.
  • Has a pre-filter for removal of large particles.
  • It has an filter replacement indicator.


  • Only can be used for standard faucets.
  • The quality of the inlet is not the best.
  • Filter may clog up easy.


PUR PFM400H so far is the most compact faucet water filter in the market.

Compared to the DuPont model, this one also has a nice looking design.

In terms of the filtration process, it has three (3) stages to remove most contaminants. This is more than what other manufacturers offer.

Despite of having a few stages, it offers similar features as in filtering life. It is more sophisticated than what the Brita model offers.

All those things can sound good but we know there are some limitations. One of the most important ones is the overall weight of the system.

In saying that, you can find more information about the PUR advanced faucet filtration system pfm400h by reading our full review.

PUR PFM400H Faucet Filter Review

  • Installation only takes a couple of minutes.
  • You can decide to either filter or not the water by turning on and off the lever.
  • Three filtration stages for more clean water.

  • Standard faucet design ONLY.
  • Only municipal water can be filtered.
  • Filter’s lifespan is not awesome.

Culligan FM 25 faucet mount filter

The last of the list, the Culligan FM 25. If you are looking for the smallest faucet filter in the market, this is the one.

Its size is actually an advantage considering that nowadays houses are smaller, therefore their kitchens too.

Compared to the other models, this one does not have an indicator to advise when the filter needs replacement.

Aside from the above, I really like that the filter goes unnoticed at the faucet.

No matter how small this filtration system could be, surely there are some other aspects to uncover. Is this the right for you? Check the review.

  • Lightweight and small for tiny kitchens.

  • Filter housing could get compromised easily if too much accumulation of sediments.
  • Lack of a filter replacement indicator but not a big deal.
  • As most other faucet water filtration systems, this one is ONLY useful for standard design taps.

Now that you know more about what are the best faucet water filter for 2020, it is time for you to learn more about this type of systems.

How Does a Filter Faucet Work?

Like most water filters, a faucet filter works in a simple way. It consists of a cartridge filter that traps contaminants and, in some cases, even uses agents capable of killing viruses and bacteria, such as silver particles.Filtration process faucet filters

The water filter faucet is easy to install on your sink’s faucet; once installed, all water will run through it and will reach your glass cleaner and healthier.

Most systems can remove:

  • Sediment: Most tap water filters can trap small particles of dust, debris, sand, and sometimes even rust from old pipes. Furthermore, they can also block certain parasites such as giardia and cryptosporidium.
  • Chemicals: Manufacturers usually equip their water filters with activated carbon blocks and other types of filters capable of removing common contaminants like chlorine and fluoride, nitrites and nitrates, and sometimes even heavy metals like lead and mercury.
  • Bad smell and taste: By removing contaminants, faucet filters also remove the bad smell and taste of your drinking or cooking water, improving its quality.

Water Filter Faucet Pros and Cons

A faucet mounted water filter can be a great solution if the quality of the water in your area is not too bad, but you still want to make sure your family is getting the best possible water. The main advantages of these filters include:

  • Healthier water: Whether you’re connected to the municipal water supply or get it from a tested well, the tap faucet filter will still block many contaminants, improving the quality, taste and smell of your drinking water.
  • Easy to install: Unlike the more complex under-the-sink water filters, tap water filters are very easy to install. Most homeowners can have their new filter up and running in less than 10 minutes.
  • Convenience: Faucet water filters will provide you an endless supply of clean water at a fraction of the cost of an under-the-sink filter. Undoubtedly, a better solution than a water filter pitcher for a larger family and a more affordable one for homeowners on a budget.


Before buying a water filter faucet though, you should also be aware of its limitations. This system is not designed to purify water. It only removes pollutants such as sediment and chemicals.

Although some filters include components that could potentially kill bacteria and viruses, that is not a guarantee.

That’s why these filters are ideal to use to treat municipal or tested well water, but not untested well water. This is something you should do before buying any type of water filter.

Choosing a Water Filter Faucet: Tips

Before buying a faucet water filter system, you should weigh in a few factors that could make or break the deal, such as the contaminants you want to remove, maintenance, and required sink space.

What Needs to Be Filtered

Most people buy a water filter system to remove specific contaminants in their area. Be it chlorine, fluoride, byproducts from pesticides and herbicides, or large particles such as dust and debris, make sure the filter you buy can handle them.

Manufacturers usually provide lists of the contaminants their filters remove, so it should be easy to determine whether a specific model is right for you.

Sink Space

Faucet water filters are installed on your sink’s tap, so they don’t require too much space. However, some models are more cumbersome than others. If you have a small sink, a smaller filter could be a better choice, such as a Alexapure Pro, which is a gravity fed water filter, adjustable and convenient too.

Required Water Pressure

Most faucet filters don’t have specific water pressure requirements, but you should know that the filtering process will slow down the output rate. If you don’t have enough pressure without the filter, getting a glass of clean water with it on can be painfully slow.

Water Filter Life

A longer filter life means less maintenance and lower overall costs. Some brands require you to change the filters when you’ve reached a certain quantity of filtered water, others, after a specific time.

The easiest way to keep maintenance under control is by getting a water filter faucet with filter change indicator, something that the best brands can provide.

Swivel Capability

Since this type of water filter goes onto your sink tap, it is essential to get one that can swivel. This may seem unimportant at first, but it really makes a difference, especially when you’re washing large pots or pans.

Best Faucet Water Filter Brands for 2020

There are many brands that produce faucet water filters, but the three (3) below are renowned for their reliability, quality control, and long-lasting products.


Brita is a German company and one of the biggest names in the water filter industry. Their products vary from water filter pitchers to kettles and tap attachments, all of which use activated carbon filters and ion exchange resins to remove most contaminants including chlorine and its compounds, some pharmaceuticals, and heavy metals.


Another company renowned for its tap water filters, pitchers, water dispensers and coolers, Pur is known for the reliability of its products. Their faucet mounted filters incorporate some of the latest filtration technologies (such the PUR PFM400H on tap filter) as well as user-friendly features, including Bluetooth connectivity, which is really cool, and maintenance alerts.


Founded in 1936 in the USA, Culligan is now present in over 80 countries. Their range of products includes tap mounted filters as well as under-the-sink and whole-house water filter solutions. The faucet filters remove chlorine, lead, and particulate matter, and are available in multiple finishes you can match with your kitchen décor.

Wrap Up

A kitchen faucet water filter is a great alternative to a water filter pitcher if you consume more than a few gallons of water a day. This system is convenient, cheap, and fairly effective. It won’t provide pure water like reverse osmosis or whole house filter, but it could be a great solution if you only want to remove common contaminants, such as chlorine or some heavy metals.

They also don’t produce wastewater, have a good filtering capacity, and are environmentally friendly, a few more reasons to consider such a water filter system for your home.
