Choosing The Best Faucet Water Filter For Your Home

You shouldn’t just go out to the store and buy the first water filter that you see. There are considerations you must make to ensure that you are getting the most out of your filtration system. Here are some of them:

To Eliminate All Pollutants And Contaminants

When choosing the best faucet water filter for your home, you need to carefully read the various labels to establish which contaminants will be filtered with each faucet water filter model.

Dirty Water Pouring From Faucet

Reverse Osmosis (RO) filtration systems are known to eliminate most pollutants and contaminants from water, including heavy metals and viruses.

It is worth noting that some filters rely on total dissolved solid (TDS) controllers and additional minerals to improve the taste of water. That said, people often do not realize that these types of filters do not fully eliminate viruses, metals, or limescale.

The best faucet water filters should eliminate most of the following:

  • Fluoride
  • Chlorine
  • Lead
  • Mercury
  • Polychlorinated Biphenyls
  • Arsenic
  • Dichloro Diphenyl Trichloroethane
  • Dioxins
  • Hexachlorobenzene
  • Dacthal
  • Perchlorate

To Make Maintenance Manageable

The term “you get what you pay for” applies to water filtration systems as well. Choosing the best faucet water filter for your home is essential because buying a cheap model could lead to unexpected maintenance.

Man Doing Faucet Maintenance

Aside from avoiding any unnecessary, long-term maintenance costs, choosing the best faucet water filter will help stop secondary contamination. This is especially true with filters equipped with plastic tanks that are not airtight.

Plastic tanks are not only prone to bacteria growth but also untightening which can allow contaminants such as dust and insects to enter the water.

Things To Consider When Choosing The Best Faucet Water Filter

The best faucet water filters are made of the highest quality materials in order to avoid contamination from your water as well as secondary contamination from the filter’s own materials. To achieve the above, you must consider the following:

Your Water

Before you can make a buying decision, you need to know what you are up against. There are a number of ways you can find out what truly lives in your water. You can visit your local government website where the information legally has to be made available.

Man Pouring Water In Glass

Call the EPA’s Safe Drinking Water Hotline to find certified labs that will send cheap, if not free testing kits or you need to know the exact contaminants in your water, as well as any particles, heavy metals, bacteria, and viruses.


The best faucet water filters on the market today are subject to strict product testing to ensure they provide the same results as promised on the manufacturer’s label.

We suggest you choose a filtration system that has been certified by an American National Standards Institute accredited-certification body such as the WQA Gold Seal or NSF.

If you want to double check if the filters you are considering are certified, visit the WQA1 and NSF2 websites. Both websites will require you provide them the name of the manufacturer, brand of the filter, and various other pieces of information.

Filtration Technology

The type of filtration technology your home needs will depend on the contaminants in your water. However, there are some filtration technologies that are considerably better than others.

Reverse Osmosis Water Filter System

Some people rely on water softeners, but although these can reduce calcium and magnesium buildup in your water, they do not remove the majority of other contaminants.

On the other hand, mechanical filters are known for removing certain sediments but are unable to filter out chemical contaminants.

That said, if you find that the best faucet water filter for your home is mechanical, see if you can purchase one that works in conjunction with a second filtration technology to reduce additional impurities.

RO filters use pressure to push water through a membrane that then traps contaminants. The best thing about RO filters is that they can turn any water into potable water.

Not only this, they normally come as part of a wider set of technologies meaning that the scope of impurities they can filter through is abundant.

The most common, and often best faucet mount water filters are those that use carbon. Although they range in effectiveness depending on the model, the latest ones can filter out a huge variety of viruses, bacteria, metals, mercury, and even asbestos.

The Size And Capacity Of Your Filter Versus Your Space

When choosing the best faucet water filter for your home, you need to look at the size of the filter and the amount of space you have for it.

Pouring Water From Faucet

For example, under the sink filters are tucked away whereas countertop filters sit beside your sink. If you are already struggling for space in your home, you need to consider all your options.

Aside from the size of your filter and the space you have to store it, you need to consider how many people are going to be using it on a day-to-day basis.

Pitcher water filters are great and simple to use, however, their capacity is minimal and can only be used as a basic supply of drinking water.

Faucet water filters offer you an unlimited supply of water straight from the tap, so if you have a larger household consider a more permanent filtration system. With them, you can also choose between filtered and unfiltered water.

Filter Change Indicators

The best faucet water filters measure how much water you have consumed and send you some form of alert when your filter is reaching its last leg of life.

These alerts normally come in the form of a flashing light or timer and are a great way to remember to do regular maintenance.

Faucet Water Filter Change Indicator

By not remembering to change your filter as per the manufacturer’s requirements, your water pressure will slow and contaminants will enter your drinking water, thus making your filter useless.


Often, cheap filtration systems do not fit on certain faucets. The best faucet water filters are compatible with a huge variety of faucets, plumbing, and sinks.

If you want your filtration system to be more versatile, opt for a faucet water filter for which you can buy accessories such as extension hoses.

You may also be able to find your preferred filter system in a finish that matches that of your kitchen or bathroom so that it is more aesthetically pleasing.


Despite your health not having a price tag on it, it is worth noting that you don’t have to make an enormous investment to find the best faucet water filter.

Handgiving Money

Also, bear in mind that your filtration system will need regular maintenance so you should do some simple math if you have a tight budget.

The best way to establish how much your water filter will cost is to look at the price of the system, the cost of replacement filters, as well as manufacturer recommendations regarding filter life in order to estimate your yearly expenses.

Other considerations to make regarding costs will depend on the filter you choose. You may need to clean it regularly and you’ll inevitably have to replace batteries or the permeable membrane at some point or another.

Lastly, check if you only have limited a supply of discarded waste allowance and make an inquiry regarding your municipal water rates.
