Replacing the Aquaphor filter: instructions for all models with photos and videos

Why is it important to change the filter in the Aquaphor system on time?

Filters Aquafor They purify water from chlorine, heavy metals, pesticides and mechanical impurities, but over time their resource is exhausted. If you ignore replacing the cartridge, the quality of the water will deteriorate: there will be an unpleasant taste, smell, and in the worst case, the accumulation of dangerous bacteria. The manufacturer recommends updating filter elements every 6–12 months (depending on the model and intensity of use), but the actual period depends on the water hardness in your region.

Untimely replacement leads not only to deterioration of cleaning, but also to damage to the filter housing due to sediment accumulation. For example, in models Aquafor Crystal Eco and Morion a clogged cartridge increases pressure on the O-rings, which can cause leaks. In this article we will look at how to correctly change the filter in different systems. Aquafor, avoiding common mistakes.

How to determine when it’s time to change the Aquaphor filter

The manufacturer indicates the average cartridge resource (usually 3000–6000 liters), but actual signs of wear may appear sooner. Please note:

• 💧 Changing the taste of water - bitterness, metallic taste or smell of chlorine appears.
• ⏳ Pressure reduction — water flows in a thin stream, although the pressure in the system is normal.
• 🔍 Visible dirt — in a glass of filtered water, rust particles or turbidity are visible.
• 📅 Service life expired - even if the water seems clean, the cartridge loses effectiveness after 6-12 months.

In models with resource indicator (for example, Aquafor DWM-101S Morion) the red light comes on. If it is not there, keep a record of the installation date or use resource calculator from the manufacturer.

⚠️ Attention: Don't wait until the water becomes cloudy! In cartridges Aquafor activated carbon is used, which over time turns into a breeding ground for bacteria. Replacement on a schedule (every six months) is cheaper than treating intestinal infections.

Preparing for replacement: tools and safety precautions

To replace the filter on most models Aquafor No special tools are needed, but prepare:

• 🔧 Filter key (included with the system).
• 🧽 A rag or towel - for collecting spilled water.
• 💦 1-2 liter capacity (under draining the remaining water from the flask).
• 🧴 O-ring lubricant (silicone or food grade, for example, Dow Corning 111).

Before starting work:

1. Turn off the water supply to the filter (usually the tap is located under the sink).
2. Open the drinking water tap to relieve pressure in the system.
3. Place a rag under the flask - when unscrewing, up to 0.5 l water.

Step-by-step instructions: how to change the cartridge in Aquaphor

The replacement algorithm is the same for most flow systems (Crystal, Morion, Favorite), but there are nuances for models with reverse osmosis. Let's consider the universal method:

1. Remove the flask.

   Place the key on the flask and turn counterclockwise. If it does not give in, press harder - the thread usually does not “stick”, but force may be required.

   What to do if the flask does not unscrew?

   If the bulb does not budge, wrap it in a dry cloth for better grip. Do not use pliers - they will damage the plastic. As a last resort, gently tap the key with a rubber hammer to remove any limescale deposits.

2. Remove the old cartridge.

   Pour the remaining water from the flask into the prepared container. Remove the used filter and rinse the flask with warm water (no detergents!).

3. Install a new cartridge.

   Check if the model matches (there should be markings on the case, for example, B510-08 for Crystal Eco). Insert it into the flask so that the O-ring fits snugly against the edge.

4. Lubricate the seal.

   Apply a thin layer of silicone grease to the rubber ring of the bulb - this will prevent leaks and make the next replacement easier.

5. Assemble the system.

   Twist the flask clockwise manually until it stops, then tighten it with a wrench (do not overdo it - 1–1.5 turns is enough).

For reverse osmosis systems (Aquafor OSMO) additional replacement is required membranes (once every 2–3 years) and post filter (once a year). Their location is indicated in the instructions for the model.

⚠️ Attention: If after replacement the water flows cloudy or with black particles, this is normal for the first 10–20 liters. This washes out the coal dust. If the problem persists, check the sealing ring for leaks.

Comparison of cartridges for Aquaphor: which one to choose

The manufacturer offers several types of filters that differ in composition and purpose. Below is a table with popular models and their features:

Cartridge model	Filtration type	Resource (liters)	Suitable for systems	Features
B510-08	Coal block	6000	Crystal Eco, Morion	Removes chlorine, pesticides, improves taste
B510-11	Ion exchange resin	4000	Favorite, Crystal A	Softens water, reduces hardness
B510-13	Ceramics + coal	5000	Morion DWM-101	Retains bacteria and mechanical impurities
RO-1812-50	Reverse osmosis membrane	15000	Aquafor OSMO	Purification at the molecular level (98% impurities)

Optimal for most regions of Russia B510-08 (coal), but if the water is hard (for example, in Moscow or St. Petersburg), it is better to combine it with B510-11 (softening). Membrane in reverse osmosis systems RO-1812-50 changed less often, but its cost is higher - from 2500 rub.

Common mistakes when replacing a filter and how to avoid them

Even experienced users sometimes make mistakes that shorten the life of the system or deteriorate the quality of the water. Let's look at the most common ones:

• 🔧 Tightening the flask with a wrench.

  This deforms the threads and seal, causing leaks. Screw the flask manually all the way, and do no more than half a turn with the key.

• 🚰 Ignoring flushing after replacement.

  The first liters of water contain coal dust. If you don't drain them, it will end up in the kettle or food.

• 📅 Replacement of only one cartridge in a multi-stage system.

  For example, in Aquafor Trio you need to change all 3 filters at the same time, otherwise the cleaning efficiency drops by 40–50%.

• 🧴 Using unsuitable lubricant.

  Vaseline or machine oil destroys the rubber of the seals. Silicone grease only!

Another common problem is cartridge model mismatch. For example, in Crystal Eco the filter from Morion DWM-101, even if they look similar. Always check the markings on the body of the old cartridge before purchasing a new one.

How to extend the life of the Aquaphor filter

The average cartridge life can be increased by 20–30%if you follow simple rules:

• 💧 Use a pre-filter.

  Mechanical coarse filter (e.g. Aquafor Gross) retains rust and sand, reducing the load on the main cartridge.

• 🌡️ Monitor the water temperature.

  Optimal range - 5–35°C. Hot water destroys the carbon filter, and cold water reduces the effectiveness of ion exchange resins.

• 🔄 Flush the system after long periods of inactivity.

  If the filter has not been used for more than a week, drain the first 2–3 liters - bacteria accumulate in them.

For reverse osmosis systems (Aquafor OSMO) critical change prefilters regularly (once every 3–6 months). They protect the membrane from clogging, and its replacement costs 3–5 thousand rubles.

FAQ: Frequently asked questions about replacing Aquaphor filters

Can the filter bowl be washed in the dishwasher?

No! Aggressive detergents and high temperatures destroy plastic and O-rings. Wash the flask only with warm water and a soft sponge (no abrasives).

What should I do if, after replacing the filter, water flows from under the flask?

Most likely, the o-ring is not seated tightly. Turn off the water, remove the flask, check the ring for cracks and lubricate it with silicone grease. Then screw the flask back on without overtightening.

Which cartridge to choose for water with the smell of hydrogen sulfide?

A specialized filter is suitable for removing hydrogen sulfide. Aquafor B510-14 with activated carbon and catalytic layer. It oxidizes hydrogen sulfide to harmless sulfur.

How much does it cost to replace a filter at a service center?

Cost of work in official centers Aquafor - from 500 to 1500 rub., depending on the model. But the procedure is so simple that it is more profitable to do it yourself.

Is it possible to use cartridges from other brands (Barrier, Geyser) in Aquaphor?

Technically possible if the dimensions and type of filtration match. However, the manufacturer does not guarantee the quality of cleaning, and the O-rings may not fit. The risk of leaks and poor filtration is higher.
