The quality of tap water often leaves much to be desired, and many households install flow filters to purify it. The most popular solution on the market is the company's products Aquaphor, which offers a wide range of cleaning systems. However, even the most advanced filter will cease to perform its function if its internal content is not updated in a timely manner. Timely replacement of replacement modules is not just a manufacturer’s recommendation, but a necessity for maintaining the health of the whole family.
The resource of any cartridge is limited, and after its sorption capacity is exhausted, it can become a source of secondary pollution. Water passing through the module, which is oversaturated with harmful substances, carries accumulated bacteria and chemicals back to the tap. Regular replacement filtration elements ensure that you and your loved ones drink clean, safe and healthy water every day. In this article we will examine in detail the process of replacing modules for various filter models.
Replacement intervals and signs of filter wear
The manufacturer indicates the average life of the cartridges, but the actual lifespan depends on the quality of the source water and the intensity of consumption. The standard resource of K series modules is about 6000 liters or 6 months of use, whichever comes first. If the water is hard or contains many impurities, the resource may deplete faster. Ignoring the timing of replacement leads to a decrease in water pressure and a deterioration in its taste.
How to understand that a module has exhausted its resource? The first signal is often a change in the taste of the water: a taste of metal or chlorine appears. The filtration rate can also be significantly reduced, which is especially noticeable in reverse osmosis systems or flow-through main filters. Changing the cartridge is required immediately if you notice these signs, even if less than six months have passed since the last replacement.
⚠️ Attention: Do not try to rinse carbon cartridges with hot water to restore their properties. This destroys the structure of the sorbent and makes the module unsuitable for further use.
To accurately control deadlines, it is recommended to keep a special journal or use reminders in your smartphone. Write down the installation date of each new module directly on its body with a marker. This will help avoid confusion, especially in systems that use different types of cartridges (mechanical, carbon, softening). Aquaphor offers different series of modules, and it is important not to confuse their purpose when purchasing new ones.
Necessary tools and workplace preparation
The process of replacing modules in filters Aquaphor does not require complex professional equipment, but some training is required. You will need a clean towel or rag to cover the work surface under the sink as it can get damp there. Also prepare a container for draining the remaining water from the flasks and a new set of replacement modules itself.
In most cases, special tools are not required, since the housings are often unscrewed by hand. However, some models, especially older versions or systems with a threaded connection, may require a special wrench included in the kit, or a regular plumber's wrench (with caution). Make sure you have access to a shut-off valve to shut off the water supply before starting work.
- 🧼 Clean rags or paper towels for cleaning up spilled water.
- 🔧 A special key for unscrewing the flasks (usually included with the filter).
- 🥣 Basin or bucket for draining water from the filter housing.
- 🧤 Disposable gloves for hygiene.
Before starting work, be sure to turn off the water supply to the filter. If you have a storage tank system, it is also recommended that you open the clean water tap to relieve pressure in the system. This will prevent water from splashing when unscrewing the flasks. Security and accuracy at this stage will save you time on cleaning.
Replacing modules in flow-through filters under the sink
The most common type of household filters is flow-through systems consisting of several flasks. The modules in them are replaced sequentially. First you need to remove the flasks. In modern models Aquaphor (Crystal, Trio series) a quick replacement system is often used, where the flask is simply unscrewed counterclockwise. In older models, unscrew the flask itself with a wrench.
After removing the flask, remove the used module. Carefully inspect the inner surface of the flask: if there is mucus or plaque on the walls, rinse it with warm water without using household chemicals. New series modules K1, K2, K3, K7, K7M Ready to install straight away, no need to rinse or soak. Insert the new cartridge into the flask until it stops, aligning the guides.
☑️ Replacement algorithm for a flow filter
When installing modules, it is important to follow the correct sequence if they have different purposes. Typically, water first undergoes mechanical purification (5 microns), then carbon, and finally finishing (0.1 microns or ion exchange). Do not confuse the order in which the modules are installed, as this can lead to rapid failure of the finishing cartridge. After assembly, turn on the water and check the connections for leaks for 10-15 minutes.
Features of replacement in reverse osmosis systems
Reverse osmosis filters have a more complex design, including a membrane and a mineralizer. The replacement procedure here depends on the type of housing. In systems with classic flasks (10SL or 10BB), the process is similar to flow-through filters: the flask is unscrewed and the cartridge is changed. However, in the models Aquaphor Osmo with modules like K1O, K2O, K7M a quick replacement system is used, where the module is inserted into the housing and turned until it clicks.
Particular attention should be paid to the reverse osmosis membrane. Its resource is much longer - from 1.5 to 2 years, but it also requires replacement. When replacing prefilters (mechanical and carbon), the membrane does not need to be touched. If you are changing the membrane itself, make sure that the rubber seals on it are lubricated with food-grade silicone (usually already applied) and are not damaged.
After installing new modules in a reverse osmosis system, it takes time to fill the storage tank. This may take from 2 to 5 hours depending on the pressure in the water supply and the condition of the membrane. It is better to drain the first portion of water from the tank after replacing the cartridges, as it may contain activated carbon dust from the new filters.
⚠️ Attention: When replacing the reverse osmosis membrane, strictly monitor the direction of flow. There is an arrow on the membrane body indicating the direction of water movement. Installation on the contrary will lead to damage to the element.
Table of compatibility and resource of Aquaphor modules
In order not to get confused in the variety of cartridges, it is important to know the markings and purpose of each module. Company Aquaphor uses a single designation system for most of its filters, which simplifies the selection of consumables. Below is a table of the main modules, their resource and purpose.
| Module model | Cleaning type | Resource (liters) | Service life (months) |
|---|---|---|---|
| K1 (5 µm) | Mechanical | 6000 | 6 |
| K2 (Carbon) | Carbon sorption | 6000 | 6 |
| K3 (0.1 µm) | Fine cleaning | 6000 | 6 |
| K7M | Mineralization | 6000 | 6 |
| K1O (OSMO) | OSMO pre-treatment | 6000 | 6 |
The use of original replacement elements guarantees the declared quality of cleaning. Compatible third-party cartridges may differ in geometry or fill quality, which can lead to leaks or contaminant leakage. Always check the packaging for holograms and security codes when purchasing.
Cleaning and servicing the filter housing
Replacing the module is also an excellent opportunity to inspect the filter housing itself. Over time, plastic flasks can become covered with plaque, which is a favorable environment for the growth of bacteria. Regular cleaning of internal surfaces extends the life of the entire system.
To clean, use a soft sponge and warm water. Aggressive detergentsIt is strictly prohibited to use products containing chlorine or acids, as they can damage plastic and rubber seals. If bioslime has formed on the walls, you can soak the flasks in a weak solution of citric acid for 15-20 minutes, then rinse thoroughly.
What to do if there is a whistling sound when the filter is operating?
The whistling sound often occurs due to the high speed of water passing through the narrow channels of the new cartridge or when the pressure in the system is low. Usually this sound disappears after 2-3 days of use. If it persists and is accompanied by vibration, check the tightness of the connections.
Don't forget to check the condition of the rubber O-rings. If they have lost elasticity, cracked or flattened, they must be replaced. Dry rings can be lubricated with food-grade silicone for better sealing, but if there is mechanical damage, only replace them. The tightness of the system is the key to avoiding flooding in the kitchen.
Typical mistakes when replacing yourself
Despite the simplicity of the procedure, users often make mistakes that negate the effectiveness of filtering. One of the most common is incorrect installation of the module. If the cartridge is not tightened or is skewed, water will pass by the filter element, carrying away contaminants. Always check that the module is seated straight and all the way.
Another mistake is neglecting to flush new cartridges. After installing any new module, you need to pass 5-10 liters of water through it. This is necessary to remove the preservative (edible glycerin) and coal dust. It is not recommended to drink water immediately after replacing; it may have a black tint and a strange taste.
- 🚫 Forgot to turn off the water before starting work (leads to a flood).
- 🚫 The sequence of cartridges was mixed up (disables the system).
- 🚫 Didn't check the O-rings for debris.
- 🚫 Used hot water to wash the flasks (plastic deformation).
Before installing a new cartridge, remove all protective films and plugs, if any, from it. A forgotten protective film completely blocks filtration.
Also, users often forget to relieve the pressure in the system before unwinding. This leads to the fact that when the flask is unscrewed, water flows under pressure, flooding the cabinet under the sink. Always open the clean water tap after closing the inlet valve to release any residual pressure.
Frequently asked questions (FAQ)
Can Aquaphor carbon cartridges be washed and reused?
No, carbon cartridges and modules with ion exchange resin cannot be washed and regenerated at home. Washing with water only removes surface dirt, but does not restore the sorption capacity of coal. Reusing a used cartridge is hazardous to health.
What should I do if water flows poorly after replacing the cartridge?
A decrease in pressure immediately after replacement is normal, since the density of the new filter material is higher than that of the caked old one. If the pressure does not recover after a couple of days, check whether the module is installed correctly and whether the tube is pinched during assembly.
How to dispose of old replacement modules?
Used cartridges are classified as household waste, but contain accumulated contaminants. It is recommended to pack them in a plastic bag before throwing them into the general trash. It is usually not necessary to take them to special plastic recycling points, since the internal filler is difficult to remove.
Is it possible to install cartridges with a longer lifespan than the manufacturer recommends?
Technically, it can be installed if the dimensions allow, but this is not always advisable. If the module has a longer resource in liters, but a lower degree of purification, the water quality will deteriorate. If we are talking about a larger cartridge, it may simply not fit into a standard-sized flask.
The main secret to a long filter life is not only timely replacement of cartridges, but also regular hygiene of the flasks themselves and checking the tightness of the connections.
