Best Ceramic Water Filter: A Top 5 Review

Best Ceramic Water Filte

There are various types of filtration systems available on the market, and it may be challenging to choose the best one. Ceramic filters are old yet popular filters for home use, thanks to their effective operations and cost-effectiveness. The half-micron sized pores on the ceramic candles eliminate impurities from water like bacteria, dirt, and debris.

These can be used in different water filtration systems like countertop water filters, under-sink filters, portable filters (gravity water filters), or more – especially those that feature reverse osmosis functions. Its usage in refrigerator water dispensers is also quite common. Ceramic water filter systems are easy to install. These ceramic candles/cartridges are made of activated carbon and contain silver ions that help remove chemical and living organism contaminants.

If you want to prioritize your health and well-being, here are the five best ceramic water filters on the market that provide clean drinking water.

How To Choose the Best Ceramic Water Filter

Before you decide which is the right ceramic water filter for your needs, here are some things to consider before making a choice.

Type of Ceramic Water Filter

A ceramic water filter should be purchased in accordance with the space you have in your kitchen. For example, countertop water filters sit on your kitchen counter. Additionally, there are two types of countertop water filters – a gravity filter or a built-in dedicated faucet filter that has a hose that attaches to your existing faucet.

There is also an under-sink type that is mounted under your sink, as the name implies. Other types are portable and pot-type ceramic water filters. Each type requires a specific kind of ceramic cartridge, so check the suitability of the filter and buy accordingly.

Filter Capacity

Ceramic candles come in varying capacities. Opt for enhanced capacity to effectively remove any harmful bacteria and deliver safe and clean water. Filter capacity depends on your everyday water consumption and water supply, so check your family’s needs and then decide on the water holding capacity of your ceramic water filter.

For example, a portable backpacking water filter can carry a small amount, so candles that have a small filter capacity are best. Otherwise, if you have a countertop system with 8-10 liters capacity, search for a high-capacity cartridge. Don’t forget to test the product and its ability to trap the contaminants.


Durability is an important factor for every consumer product. Check the warranty and built-in material before purchasing any product. With regards to ceramic water filters and cartridges, the brand’s ceramic and other materials should be carefully reviewed. This material is prone to cracks and requires careful handling.


Products with complex usage should be avoided. The operations, cleaning, and maintenance are determining factors. A water filter is an important kitchen tool and shouldn’t be troublesome to use and maintain. Go for ceramic water filters that are easy to use and clean since they have a lesser maintenance cost. All types of filter cartridges need to be replaced from time to time so check their lifespan.

Budget and Price Plus Installation Cost

Invest in a good product while staying in a price range within your budget. Look for an affordable range of ceramic water filters and then make a prudent purchase. Besides the price of the ceramic water filter, there may be installation costs as well.

Some ceramic candles need professional replacement services while others are easy to install yourself. It is advisable to buy water filter systems that don’t require expensive filter cartridge replacement. To sum it up, calculate the operational cost of the machine irrespective of its type.
