Installing ceramic water filter candles is straightforward. The filtration system needs to be prepared accordingly. The filter should be soaked in clean water for at least 24 hours before installation to allow for complete absorption of water. Then, the ceramic filter should be placed in a container with an airtight lid or similar material to keep it sealed and away from dust and dirt. The container should be placed in an elevated area, such as a countertop or shelf. After that, the intake tube of the filter needs to be connected to the water supply line with an appropriate fitting, then connected to the outlet pipe and secured with clamps.
What Is A Ceramic Water Filter Candle?

A ceramic water filter candle is a type of filtration system that uses ceramic materials to remove suspended solids, bacteria, and other impurities from water. The filter consists of a hollow cylindrical candle made out of porous ceramic material with tiny pores much smaller than the diameter of human hair. The contaminants are trapped and filtered out when water passes through the ceramic. Depending on usage and maintenance, the filter can last up to 5 years.
How To Install A Ceramic Water Filter Candle?
Installing On Pressure Filter

Place the rubber O ring over the threaded mount: Carefully place the rubber O ring over the threaded mount of your ceramic water filter candle. Ensure that the O ring is inward and centered around the mount to make an airtight seal when connecting to the faucet.

Screw the candle into the housing: Take the ceramic water filter candle and screw it into the housing of the filter unit. Make sure that the candle is tightened securely to ensure a good seal. Ensure that you only use your hands and not other tools for this step.
Open the isolation valve: You need to open the isolation valve of the filter. It should be located before the filter housing so you can access it easily. Ensure all other faucets in your home are closed before you do this.

Allow the filter to stand unused for 24 hours: Place the ceramic filter candle into a large container to hold at least 1 liter (1 quart) of water. Allow the filter to stand unused for 24 hours to absorb moisture and become saturated. The more time you allow for this process, the better the results will be once you begin using it.

Open the tap again for 10 minutes: After installing the ceramic water filter candle and connecting it to your tap, open it for 10 minutes. This will clear out any loose particles that may clog up the filter.
Allow water to run to waste: After removing the filter candle from its package, allow water to run to waste for a few minutes. This will ensure that any fine particles and manufacturing debris have been cleared out before you start using it.
Installing Gravity Filters

Place the sealing washer over the threaded mount: Install the ceramic water filter candle onto the threaded mount, then screw on the locking nut. Be sure to hand-tighten the locking nut instead of using a tool.
Place the filter candle mount stem through the hole: The ceramic water filter candle needs to be installed on the top of a disk that fits the diameter of the body. Secure it firmly with a rubber gasket, washers, and screws.

Secure with a wing nut: After inserting the candle into the filter holder, secure it with a wing nut. The wing nut should be tightened until it is snug against the top of the ceramic water filter candle. When done correctly, this will ensure a tight seal and prevent leaks.

Fill the upper container with cold water: Pour cold water over the ceramic filter candle until it is submerged and the bottom chamber of the container is filled. Make sure not to fill it past the top edge of the candle, as this could cause leaking.
Discard the first filtered water: After inserting the filter into the ceramic water filter housing, turn the filter counterclockwise until it is tight. Connect the inlet and outlet pipes to their respective openings in the housing. Turn on the water supply to flush out any small particles of dirt or dust that may have been present inside the housing.
Repeat the process: Reinstall the ceramic pot cover after inserting the water filter candle into the holder. Make sure to secure it with rubber washers and metal bolts tightly. Ensure no gaps between the two parts so that no water can escape them.
Run at least 1 liter of water to waste per fitted filter to flush out any impurities in the filter and prevent them from entering into drinking water. If possible, run up to 3 liters of water through each new filter before connecting it for use.
Wipe the lower chamber with a clean cloth: wipe down the lower chamber of the filter with a clean cloth or other soft material. This will help ensure that no dirt or debris is caught in the upper chamber.
How Does A Ceramic Candle Water Filter Work?

A ceramic water filter candle is a type of water filter that uses a cylindrical-shaped ceramic cylinder as the filtering medium. This porous ceramic material traps sediment, chemicals, and other contaminants while allowing clean water to pass through. The pores are so tiny (less than one micron) that they can trap bacteria and cysts. This makes the ceramic filter ideal for purifying water from streams, rivers, and lakes.
Cleaning And Maintenance Tips
Rub the surface of the filter to restore water flow: Occasionally, the ceramic water filter candle needs to be cleaned with a soft brush and cold running water. This process is known as “scrubbing.” To keep your ceramic water filter candle running efficiently, it is advised that you scrub it once in two weeks or depending on how frequently you use it.

Do not use detergent for cleaning: When cleaning ceramic water filter candles, it is essential to note that detergent should not be used. Detergents contain harsh chemicals that could damage the filter candle’s surface and reduce its effectiveness. Instead, use a soft cloth or brush, warm water, and vinegar to help remove any build-up from the candle’s surface. Be sure to rinse the candle after cleaning thoroughly.
Run and waste one liter of water before use: Run the filter for 1 liter without a candle to flush out any dirt in the filter. After letting the water run and waste away, proceed to install the ceramic water filter candle.

Wear rubber gloves for installation: Wear rubber gloves to protect your hands from any dirt and bacteria on the filter and make it easier to grip.
FAQs
Do we have to boil the water before putting it in the filter?
No, you don’t need to boil the water before using a ceramic water filter candle. The filter is designed to remove bacteria and other contaminants usually found in untreated water. If the water has been boiled before, it will not be filtered properly. So make sure to use unboiled water when filtering with a ceramic water filter candle.
How often should I change the candle?
Changing your ceramic water filter candle every 6 to 12 months is recommended. The replacement rate will depend on the level of contaminant present in your water source and how frequently you use the filter. You can usually tell when it’s time for a new filter by noticing a decrease in flow rate or by sensing a smell or taste from the water.
Are ceramic candles worth using?
Yes, ceramic water filter candles have been proven to be an effective and economical means of removing contaminants from water. Ceramic filter candles are made of fine-pored ceramic material capable of trapping impurities like sediments and bacteria while allowing clean water to pass through.
What is the best material for a water filter?
The best material for a water filter is ceramic due to its ability to capture a variety of contaminants. Ceramic filters have pore sizes that range from 0.2 microns to 50 microns and can remove up to 99% of bacteria and protozoa when used correctly.
Conclusion
Installing a ceramic water filter candle can be a simple yet effective way to improve the quality of your drinking water. Before installing, you should check the cartridge’s size and design to ensure it fits properly into your existing filter system. Make sure to use only new cartridges that have not been previously used. Additionally, take care when handling the ceramic water filter candle and cartridges since they can break easily. Properly sanitize your filter system before using it for the first time.
