A quick way to have safe water to consume is through the use of ceramic filters to filter out contaminants present in your tap water supply. This a great and easy means to keep yourself and your household safe from negative health implications contaminated water may cause.

What is ceramic water filter

Viruses, bacteria, sediments, minerals, heavy metals, and chlorine are only some of the harmful substances that might be present in your untreated water supply. This is enough reason to filter your water for safe consumption.

The ceramic water filtration system was invented by Henry Doulton in 1827. This system uses a ceramic filter cartridge which is also known as a ceramic filter candle. This cartridge filter has minute pores that can filter out particles larger than them and that includes the harmful contaminants found in untreated water. 

There are various means to use this filtration system and the great thing is that they usually come at a price that won’t break the bank. Plus, they are easy to use with no electricity requirement.

Buyer’s guide

Here are some of the things you should consider before buying a ceramic water filter:

Water components

To maximize your options, you might want to have your water tested to see what contaminants you’re fighting against. Different areas have different water qualities. Know what you’re dealing with to know what filter you need.


Calculate the maintenance cost together with the initial cost before purchasing.

Filtration rate

The rate at which your filter does its job is an important consideration to know which one suits best for your purpose. If you only need a filter for drinking water, you don’t need a filter with a high filtration rate. But if you need it for showering and cleaning too, you will need one with higher filtration rate.


A certification can give you an idea how well a product works as certification facilities carefully test these products.


For home use, the conventional pot-style ceramic water filter should accommodate your needs. But if you’re considering having a filter during your travels and camping trips, you might need to look for more portable options.


While most ceramic filters are made of ceramic, there are variants that are made of plastic or metal. Take note that ceramic is prone to cracks and breaks.


Ceramic water filters in general are affordable because they are relatively easy to produce. But, if you want models with additional filtering media or those made of sturdier materials, prices can increase.

And, since it will be visible on your fridge, you will be reminded to drink the good and delicious water from your filter on a regular basis.

The Santevia Gravity system appeals to me because it mimics natural filtration in the mountains. It is difficult to find filters that naturally eliminate fluoride and create alkaline water. This one-of-a-kind feature appeals to me greatly.

Water is filtered into a five-stage process that eliminates all bad from fluoride to parasites that might be lurking in your drinking water: After the water has been filtered, it flows through the magnetic energizer spout into your bottle.

Water molecules are energized and realigned when they move through the spout, making it easier for the body to consume (better hydration). The low cost of replacement filters and the system’s long life are two compelling factors to purchase it.

Because of the tank’s huge capacity, you just need to fill it every couple of days, depending on the size of your family.

RonAgua ceramic water filter kit utilizes a gravity filter that has an outer ceramic shell and an inner activated carbon. Activated carbon promotes absorption of substances that are needed to be eliminated. In other words, carbon captures any sediments and harmful organisms that may be present. In effect, you will have a better tasting water. 

Another great feature of this set is that it can self-sterilize and it can be cleaned regularly. It is durable and you’re sure to get your money’s worth because of its longevity. But do note that carbon cannot filter out metals so this may not be ideal if your tap water has significant amounts of heavy metals. Also, for best results, use this on water that’s already been pre-sterilized. This is durable and inexpensive which makes it a good run for your money.

  • Self-sterilizing
  • Great longevity
  • Good tasting water
  • Cleanable

  • The entire system is NSF 42 and 53 Tested and Certified
  • Doulton W9331032 Ultra Carb is a highly efficient ceramic micro filter which provides genuine sub micron filtration...
  • Absolute filtration efficiency to 0.9 microns
  • Particles from 0.5 to 0.8 microns filtration efficiency greater than 99.99%
  • Flow Rate 0.5 gallons per minute

Despite being simple to mount and reasonably priced, the Doulton HCPS Countertop Filter System failed to impress us. It’s not the most visually appealing device, which is important because it’ll be sitting on your counter in plain sight. However, it does provide nearly limitless filtered water on demand.

Simply connect the hose to the end of your kitchen faucet to connect this filter. Then, using the attachment’s diverter knob, direct water from your kitchen faucet to the filter. The water would then be dispensed through the filter’s dedicated faucet.

This device employs a 10×2 micro filter with carbon layer (GAC) ceramic candle and an advanced 4-stage filtration design capable of producing up to 300 litres of clean drinking water per hour. Pathogenic Bacteria, Giardia, Cryptosporidium, sediment particles up to 0.5 microns, chlorine taste/odor, and toxic heavy metals such as lead are all removed by the multilayer Ultracarb ceramic candle.

I believe that for the vast majority of people, this countertop filter device can yield excellent results. If you don’t have counter space or don’t want the diverter valve and piping above counter, it is also available as an under counter device.


  • Easy to install
  • Connects easily to an existing faucet
  • Under counter option
  • Various Doulton candles to choose from


  • Needs to be cleaned regular or clogged

How does it work?

Typically, ceramic water filtration systems rely on the ceramic water filter candle to perform the job. This cartridge has millions of small holes, averaging at half micron, which trap every particle larger than the holes. This is the initial filtration. 

Now, there’s a maze made up of sharp angles found inside the ceramic filter which furtherly traps more sediments and contaminants. Depending on the ceramic filter you’re buying, there are models in the market that have additional filtration media such as activated carbon and silver ions. The latter has self-sterilizing and antibacterial properties to furtherly enhance the water’s quality. If your water contains heavy metals, such as mercury, copper, zinc, and lead, you may want to consider opting for ceramic filters with ion exchange raisins.

As a matter of fact, there are ceramic filtration systems in the market that house all three filtration media: silver ions, activated carbon, and ion exchange resins.

Types of ceramic water filters

We all want some clean water, but there are different things to consider to identify which one works best for your household. Here are the different types of ceramic water filters:

glass of water


This variant is literally made by potters, especially as part of the Peace movement. As the term implies, a pot-type filter is shaped like a typical flower pot and it can store around 10 liters worth of water. The filtered gallons per day depends on the brand mostly.

This type has three parts:

  • Filtration unit that rests on top of either a ceramic or plastic unit connected as a socket
  • Storage unit where filtered water becomes accessible
  • Spigot or spout for easy access of the filtered water

Pot-type ceramic filters are affordable and are easy to produce. They are also easy to clean. Overall, this type is an efficient filter.


This is a more advanced type because it is built with materials holding higher standards typically coated with metal. Thus, it is safe to say that this is a more durable option. It is also helpful to note that only the outside half of the filter requires some cleaning, thus, maintenance is easy. 

This is also more versatile when it comes to attachment since it does not need perfect fitting sockets so you can be creative in how or where you want to instal it. But of course, this variant is more expensive than pot-type ceramic filters. 


Portable ceramic filters

This requires manual plumbing to jumpstart the filtration process and are best used for camping trips and other outdoor activities due to the small size.

Inline ceramic filters

This variant filters the water that flows through the plumbing system of the house.


Gravity filters

  1. Put one bucket on top of the other while keeping the lid of the bottom bucket on.
  2. Drill a hole at the top bucket’s base and the bottom bucket’s lid. The hole should be just right to fit the filter.
  3. Apply the sock over the filter and fit at the top bucket’s base.
  4. Drill holes on the side and near the base of the bottom bucket and install the spigot.

Whole-house filters

  1. Turn the water supply off and drain as much water as possibly.
  2. Cut off the pipe you want to place the filter in using a pipe cutter.
  3. Install the filter onto the pipe. You might want to check the user manual.

Under-the-sink filters

  • Turn the water supply off.
  • Take the tubing from the valve out.
  • Place the filter under the sink and put markings on the location.
  • Connect and properly fit the filter. You might want to check the user manual.
  • Hang the filter and connect the tubings.

Pros and cons


  • Naturally filtered water
  • Affordable
  • Eco-friendly
  • Flexible and versatile
  • Easy to maintain
  • Easy to install


  • Wears out quite quickly
  • Not the most effective filter for hard water supply


Are ceramic water filters great options?

Yes! These work effectively against protozoa, bacteria, and other harmful metals and contaminants.

What type of water filter removes pharmaceuticals?

Reverse osmosis water filters have the capability to eradicate all pharmaceuticals typically found in carbon and sediment filters by forcing the water through a semipermeable membrane.

Can ceramic filters remove bacteria?

Yes! Due to the small size of the pores, ceramic filters can trap bacteria and flush them away along with other contaminants. It’s worth noting that if you haven’t used the filter for 2 days at minimum, you must throw the first two liters out. Also, you will need to replace the filter once you see bubbles due to a crack that lets air exit through.

Last thoughts

The importance of a clean water supply goes without saying. There are a lot of waterborne diseases that can be prevented if we take the extra measure to add filtration systems into our homes.
