What is a Faucet Water Filter?

A faucet water filter is another type of water filter solution. It is a point of use (POU) water filtration system which is directly attached to a faucet (it is usually attached to a kitchen faucet). The way the faucet-mounted water filter works is by passing tap water through the filters which produce clean water on its own separate faucet.

Unlike other water filter solutions like a whole house water filter that has its own storage tanks, most faucet water filters produce water on demand. It also does not produce wastewater therefore everything passes through the filter as usable drinking water.

How To Pick a Faucet Water Filter?

What’s the best way to select a filter without even seeing the product?

Well, it isn’t rocket science to differentiate which is junk and which is great. Here are some guidelines on selecting a great faucet water filtration system.

Filtration Quality

Couldn’t stress more on this element. The quality of the filter is what makes the system great. No matter how technologically advanced the system is, if the filtration quality is poor, then it is a bad filter.

One thing to note is that only compares to the system that is in the same class. It doesn’t make sense to compare the quality of a faucet water filter system with one of the best under-sink reverse osmosis systems.

Some sample questions that you could ask:

  • What are the contaminants that exist in my water source? Can this filter get rid of it?
  • How well does the filter gets rid of the contaminants? What is the percentage?
  • How fine (micron rating) is the cartridge in filtering contaminants?

Cartridge Replacement / Lifespan

The lifespan of the cartridge always gives us a clue about its quality. The longer and larger the filtration capacity, the greater the system is.

A great cartridge means good technology has been used for filtration. A longer lifespan filter will decrease the yearly maintenance cost of the system.

Filter Change Sensor

How will you know if your filter has already reached its end of life? Having a filter change sensor is a great feature to have. What it does is that it notifies you using a light indicator when you need to change the filter.

Design and Built

Lastly is the design. This depends on what you need the most in your household. Do you require access to both filtered and unfiltered water? You may choose a faucet water filter with spray options. Do you need to be sleek and modern-looking? A small but compact with metal finishes may be a great choice. It is entirely up to your needs. 


The affordability is not only on the initial investment cost. You have to factor in the subsequent maintenance cost of the system.

Some system has cheap initial cost while unaffordable maintenance cost. It is to trick customers into purchasing the system.

We break down the cost of the yearly maintenance in the above table for easy comparison.

Read The Reviews

Customer reviews often give you an insight into how well the system is performing. This can save you countless hours of returning the product and repurchasing a new one to try it out.

FAQ For Best Faucet Water Filters

Will faucet water filters fit on any faucet?

Although most faucet water filters will fit on almost any faucet this is not the case for others either. It is highly recommended that you should check with the manufacturer of your faucet before investing in a faucet water filter.

Why is my faucet’s water flow so slow?

It is either the water quality is poor and requires more time and contact with the water or the water pressure may be significantly low.

Slow water flow is also an indication that the filter may have reached its end of life and that you need to change it. When it comes to water pressure, if it is around 30 PSI or lower, then your faucet water filter may struggle to push water to the media at an acceptable speed.

How often do I have to change the filters?

Each faucet water filter cartridge has a certain amount of lifespan before a replacement is needed. Most faucet water filter cartridges have an average life of up to 100 gallons or around 1-2 months which is enough already for a 1-2 person household. If your faucet water filter has a filter change indicator, then you have less to worry about when tracking filter change.
