The quality of drinking water directly affects the health of the entire family, so timely replacement of the cartridge in the Aquaphor filter is a critically important procedure. Many users find it difficult to dismantle old modules or do not know how to properly activate new ones, which can lead to poor cleaning quality or even leaks. In this article, we'll go through the replacement process in detail for different types of devices, from simple pitchers to complex reverse osmosis systems, so you can get the job done quickly and without mistakes.
The resource of any filter element is limited, and ignoring the timing of its replacement turns a useful device into a breeding ground for bacteria. Water ceases to be purified from chlorine, hardness salts and heavy metals, and accumulated contaminants begin to be washed back. Timely installation of a new module ensures that you and your loved ones will drink clean and safe liquid, while maintaining the health of the filter itself.
Before you begin, you need to prepare your work area and make sure you have all the necessary tools at hand. The process may vary slightly depending on the model, be it classic Aquaphor Run, modern Crystal ECO or compact jug Ultra. We will consider universal principles and specific nuances so that the instructions will be useful to owners of any equipment of this brand.
Preparing for replacement: tools and safety precautions
Before starting any manipulations with the water treatment system, you must shut off the water supply if you are working with a flow filter or reverse osmosis system. For jugs and faucet attachments, simply empty the container of water. It is important to have dry rags or paper towels on hand, as even with careful dismantling, a small amount of water may spill onto the table or floor.
You may need a special wrench, which usually comes with the filter housing, especially for models with threaded connections. If the key is lost, do not use pliers or screwdrivers, as this may damage the plastic elements of the case. Hull integrity is a guarantee of no leaks in the future, so careful attention to detail is extremely important.
Prepare the new cartridge in advance by removing all packaging from it. Please note that there are protective caps on the module inlets and outlets - they will need to be removed immediately before installation. Also check that the new element's markings match your filter model, as different series may have incompatible dimensions or connection types.
- 🔧 Shut off the water supply valve before starting work on flow systems.
- 🧼 Wash your hands thoroughly and wipe the surface where the replacement will be made.
- 📦 Make sure that the new cartridge is sealed and undamaged.
- 📏 Prepare a container to drain the remaining water from the system or jug.
⚠️ Attention: Never try to replace the cartridge if there is still water pressure in the system. This can lead to water hammer and damage to the connecting pipes.
☑️ Preparing to replace the cartridge
Replacing modules in filter jugs
Jug filters are the simplest type of water purification device, and replacing the cartridge in them takes only a couple of minutes. First you need to separate the funnel from the main container, if the design allows it, or simply remove the entire upper part. The old module is removed by gently rocking or turning counterclockwise, depending on the model, e.g. Aquaphor Provence or Aquaphor Orchid The locking mechanism may differ.
New cartridge, for example, popular B25 or B28, requires preliminary preparation. It must be soaked in a container of water for 10-15 minutes to activate the sorbent and remove the air lock. After soaking, the module is installed in the funnel until it clicks or fits tightly, and then the system is assembled in the reverse order.
After assembly, it is recommended to pass 2-3 full volumes of the jug through the new cartridge and drain this water. This is necessary to flush out the coal dust that is inevitably present in the new filter, and to stabilize the operation of the ion exchange resins. Only after this procedure does the water become suitable for drinking and cooking.
The first 2-3 liters of water after replacing the cartridge in the jug are best used for technical needs, for example, watering flowers or washing the floor, as they may contain a high content of coal dust.
Dismantling and installation in flow systems
Flow filters such as the series Crystal or Modern, require a more careful approach due to the presence of connecting pipes and pressure in the line. The first step is always to turn off the water supply tap and release any residual pressure by opening the drinking tap. Next, using a wrench, carefully unscrew the module flasks, starting with the first cleaning stage.
When removing the old cartridge, be prepared for water to pour out of the flask, so keep a drainage container nearby. The inside of the flask should be thoroughly washed with warm water and a mild detergent to remove any mucus or biofilm that may have formed during use. Rubber O-rings should also be inspected for cracks and, if necessary, lubricated with silicone grease.
Installation of new modules is carried out taking into account the direction of water flow, which is usually indicated by an arrow on the cartridge body. After inserting the module into the flask, the flask is screwed onto the filter body until it stops, but without excessive force, so as not to break the thread. Then turn on the water supply and check the system for leaks for 10-15 minutes.
| Cartridge type | Function | Resource (liters) | Replacement period |
|---|---|---|---|
| K1 (B100-5) | Mechanics, coal | 6000 | 12 months |
| K2 (KV-05-2) | Softening | 6000 | 12 months |
| K3 (K7B) | Postcarbon | 6000 | 12 months |
| K4 (Membrane) | Reverse osmosis | 6000 | 24 months |
Correct sequence Installation of modules is critical for the efficient operation of the system. By mixing up the flasks, you can instantly damage an expensive membrane or mineralization unit, since the water will flow unpurified or with the wrong structure.
Features of replacement in reverse osmosis systems
Reverse osmosis systems such as Aquaphor Osmosis M, have a more complex design, including a storage tank and a membrane element. Replacing prefilters (mechanical and carbon) is carried out similarly to flow-through systems, but requires the mandatory release of pressure from the tank before starting work. To do this, you need to turn off the tap on the tank and open the drinking tap until the water drains completely.
The membrane element itself changes less frequently, usually once every 1.5-2 years, and requires special care. When removing the old membrane, it is important not to damage the internal walls of the case, and when installing a new one, make sure that the rubber seals are lubricated with food-grade silicone. Tightness of connections in a reverse osmosis system, this is a key factor, since the pressure in it can reach several atmospheres.
After replacing the membrane or post-carbon, the system must be flushed for a long time, draining the first tank completely. This is necessary in order to wash out the preservative that is used to treat new membranes during production and to stabilize the operation of the automatic valve. Only after 2-3 cycles of filling and draining the tank does the water become completely safe.
⚠️ Attention: When replacing the reverse osmosis membrane, strictly monitor the direction of flow and the position of the sealing rings - an error will lead to mixing clean and dirty water.
What should I do if the water pressure drops after replacing the cartridge?
If, after replacing the modules, you notice that the water flowing from the tap is very weak, there may be air left in the system. Open the tap and let the water run for 5-10 minutes. If the problem persists, check to see if any tubes are kinked during reassembly and make sure the protective films are removed from all new cartridges.
Activation and flushing of new cartridges
The process of activating a new cartridge is not just a formality, but a necessary condition for its effective operation. The carbon blocks used in most Aquaphor filters contain fine carbon dust that will end up in your cup without rinsing. In addition, ion exchange resins must be saturated with moisture in order to begin to properly replace calcium and magnesium ions.
To activate the cartridge in the jug, simply soak it in water, as mentioned earlier. For flow-through systems, activation occurs during the initial passage of water. It is recommended not to use the first 10-15 liters of water for drinking, but to put it in a bucket for household needs. This ensures that all process contaminants are removed.
In some models, for example, in Aquaphor Morion, the flushing process may take longer due to the design of the storage tank. Here it is important to monitor the indicator (if there is one) or simply drain 2-3 full tanks. First water quality after replacement - an indicator of correct installation and flushing of the system.
- 💧 Soak the pitcher cartridge in water for 10-15 minutes before installation.
- 🚰 Drain the first 10-15 liters of water after replacing in the flow filter.
- 👀 Check the water for black sediment or foreign taste.
- 🕒 Let the system idle for a few minutes before use.
High-quality rinsing of a new cartridge removes carbon dust and preservatives, ensuring safe water quality from the first liters of use.
Common mistakes and how to avoid them
One of the most common mistakes is ignoring the timing of cartridge replacement. Users often wait until the water tastes noticeably worse, but by this point the sorbent resource has long been exhausted, and the filter can begin to release accumulated contaminants back into the water. Keep a replacement calendar or use tags on the filter housing to help you stay on track with your maintenance schedule.
Another mistake is using non-original cartridges or modules that are not suitable for a given model. Design of Aquaphor filters, especially the series Crystal, has a unique fastening system, and attempting to install an incompatible module may result in a leak. Always check the part number and compatibility before purchasing supplies.
Another common error is incorrect installation of O-rings. When assembling the flasks, it is important to make sure that the elastic fits exactly into the groove and is not pinched or displaced. The slightest distortion will lead to water dripping in, which can damage the furniture under the sink and create a risk of flooding for neighbors.
⚠️ Attention: Do not use hot water (above 40°C) to wash flasks and cartridges, as this can deform the plastic elements and disrupt the structure of the sorbent.
Can the cartridge be washed and reused?
Absolutely not. Aquaphor cartridges are disposable consumables. Washing with water can temporarily improve the pressure, but will not restore the sorption capacity of the coal and the ion-exchange capacity of the resin. Reusing an old module is pointless and unhealthy.
How to extend filter life
In order for the filter to serve as long and efficiently as possible, it is important to consider the quality of the source water. If the water in your region is very hard or contains a lot of mechanical impurities, it makes sense to install a coarse prefilter in front of the main system. This will reduce the load on the main cartridges and allow them to operate in the designed mode.
Regular visual inspection of the system will also help identify problems at an early stage. Periodically look under the sink to make sure the connections are dry. If you notice a change in the taste of the water or the appearance of plaque on the kettle ahead of schedule, it may be time to replace the cartridge unscheduled.
Using filtered water for household needs, such as ironing clothes or humidifiers, also helps save the life of drinking cartridges if you have a separate line installed for process water. However, in standard home conditions, the main thing is simply not to forget about the replacement schedule and buy original consumables.
How often do you need to change the cartridge in an Aquaphor jug?
The standard cartridge resource for a jug is about 150-300 liters or 1 month of use, depending on the model (for example, B25 or B28). If the water is very hard or you use the filter actively in a large family, you should change the module more often, focusing on the appearance of scale in the kettle.
What should I do if after replacing the cartridge the water flows black?
The black color of the water is given by coal dust, which is always present in the new filter. This is fine. You just need to continue draining the water until it becomes clear. This usually takes from 5 to 15 liters of water, depending on the volume of the cartridge.
Can Aquaphor cartridges be used in filters from other brands?
Aquaphor cartridges have a unique mounting system and dimensions, so they are usually not compatible with filters from other manufacturers (Barrier, Geyser, Atoll) and vice versa. Using incompatible modules will result in leaks or inability to install.
Do filter bowls need to be disinfected every time they are replaced?
Yes, it is recommended to rinse the flasks with warm water and a mild detergent each time you replace cartridges to remove biofilm and mucus. However, you cannot use aggressive chemicals or boil plastic flasks, as this will ruin them.
