PP waterfilter

Why the PP filter?

The PP filter is essential for reducing turbidity in the water by removing coarse particles. It also extends the life of other filters by preventing them from becoming clogged with sediment.

What type of water do you use this filter for?

The PP filter is suitable for water that contains coarse particles and sediments, such as well water, rainwater, well water, or water from surface water. We recommend always implementing a PP filter in your water treatment plant.

How does the PP water filter work?

The PP filter, also known as a sediment filter, uses a fine-mesh filter medium to remove coarse particles and dirt from the water. Think of rust, sludge, sand or algae. The filter medium captures the particles and prevents them from flowing into the water. The PP filter is available in different micron levels, including 1, 5 and 20 microns.

  • 0,2 Micron

    This filter has extremely fine filtration accuracy and can remove particles as small as 0.2 microns. This makes it extremely effective at removing microorganisms such as bacteria, some viruses and fine particles from water. This type of filter is often used in situations where extreme purity is required, such as in laboratories, pharmaceutical production, the production of ultrapure water for electronics and in drinking water treatment plants where protection against very small pathogens is necessary.

  • 1 Micron

    A 1-micron PP filter is ideal for situations where very fine filtration is required, such as sensitive equipment or applications where water quality is critical. The 1 micron PP filter is used as a final filter to filter the smallest contaminants from drinking water.

  • 5 Micron

    A 5-micron PP filter is suitable for most general applications. It can effectively remove most visible particles and sediments, making the water clearer and cleaner.

  • 20 Micron

    A 20-micron PP filter provides coarser filtration and is especially suitable for situations where the emphasis is on removing larger particles and sediments while still providing an acceptable level of filtration. This water filter is recommended as a first stage for your water treatment plant. In this way, the water filters are protected against damage in subsequent stages.

How does the CTO water filter work?

The CTO filter, also known as a Chlorine, Taste, and Odor filter or carbon filter, uses activated carbon blocks to remove chlorine, unpleasant tastes and odors from the water. The filter medium adsorbs the contaminants, purifying the water. The CTO filter has a filtration level of 5 microns.

Why the CTO filter?

The CTO filter is ideal for people who want to improve the taste and smell of the water. It provides a refreshing taste and smell to the drinking water.

What type of water do you use this filter for?

The CTO filter is suitable for water that contains chlorine, unpleasant tastes and odors, such as tap water, rainwater, groundwater and well water.

GAC water filter

Why the GAC filter?

The GAC filter is very effective at improving the taste and odor of the water by removing chlorine and other unwanted substances. The result is healthier, safer, and better-tasting water that is ideal for everyday use.

What type of water do you use this filter for?

The GAC filter is suitable for water containing chlorine, chemicals, organic substances, bacteria, and unpleasant tastes and odors, such as tap water (mainly in southern European countries).

How does the GAC water filter work?

The GAC filter, which stands for Granular Activated Carbon filter, uses a bed of activated carbon to adsorb chlorine, chemicals, organics and unpleasant tastes and odors from the water. The filter media absorbs these contaminants, making the water purified, safe and refreshing.

How does the KDF55 GAC water filter work?

This water filter is a two-stage water filter cartridge that combines KDF-55 (Kinetic Degradation Fluxion) and GAC (Granular Activated Carbon).


The KDF-55 uses a special alloy of copper and zinc to reduce chlorine, heavy metals and bacteria in the water. The filter medium converts these contaminants into harmless substances. In addition, the KDF filter can also help regulate the growth of bacteria and algae in the filter medium itself.


The GAC unit uses a bed of activated carbon to adsorb chlorine, chemicals, organics and unpleasant tastes and odors from the water.


Due to the high quality of this filter medium that combines KDF55 and GAC, an extremely wide range of impurities are filtered from the water and you are always assured of clean and safe drinking water.

Why the KDF55 GAC filter?

The KDF55 GAC water filter is particularly effective in removing heavy metals (such as lead, mercury, iron, arsenic, chromium, etc.), chemical residual products (PFAS, PFOS, PFOA, etc.) and micro-organisms (algae, pesticides and other harmful bacteria) that can negatively affect the taste, odor and health of the water.

What type of water do you use this filter for?

The KDF55 GAC water filter is suitable for water that contains chlorine, heavy metals, chemical residual products and bacteria, such as tap water, groundwater or well water.

RF waterfilter

Why the RF filter?

The RF filter is often used in applications where the presence of minerals and ions in the water is undesirable, such as in laboratories, medical equipment or specific industrial processes. The result is demineralized water with a very low dissolved solids content.

What type of water do you use this filter for?

The RF filter is suitable for water that requires demineralization, such as water for laboratory use, medical equipment or specific industrial processes.

How does the RF water filter work?

The RF filter, also known as a DI filter, uses a process called ion exchange to remove minerals, ions and most of the limescale from the water. The filter medium contains resin granules that retain the positive and negative ions in the water and replace them with hydrogen and hydroxide ions.

How does the manganese water filter work?

The manganese filter uses a special filter medium that absorbs iron contaminants from the water. The filter media binds to and traps the iron particles, effectively removing them from the water. The manganese filter is particularly effective in treating water with a high iron content.

Why the manganese filter?

The manganese filter is ideal for people who have water with a high iron content. The filter removes iron contaminants, resulting in clean and clear drinking water without unpleasant taste and odor.

What type of water do you use this filter for?

The manganese filter is suitable for water with a high iron content, such as spring water or well water or tap water. Old pipes can leave various metals in the water.

KDF85 + GAC waterfilter

Why the RF filter?

Improving water quality: KDF85 removes iron and manganese, which can improve the taste and odor of water and help reduce rust and scale in pipes and appliances.

Equipment Protection: Using KDF85 can extend the life of home appliances, such as washing machines and dishwashers, by reducing the build-up of iron and manganese deposits in these appliances.

Improving the water source: In situations where source water has a high iron or manganese content, the use of KDF85 can make the water source more suitable for consumption and use.

What type of water do you use this filter for?

KDF85 filters are particularly suitable for water sources with elevated concentrations of iron and manganese. This can be well water, well water or water from surface water sources where these metals are a problem. It is essential to have the water quality tested before deciding to use a KDF85 filter to ensure it is suitable for your specific water source and needs.

How does the RF water filter work?

The KDF85 filter works through an electrochemical reaction. It consists of a mix of copper and zinc alloys. When water flows through the filter and comes into contact with these alloys, an electrochemical reaction occurs. This reaction accelerates the oxidation of dissolved iron and manganese compounds in the water. This converts these metals into solid particles, which are then retained in the filter and removed. The result is purified water with reduced levels of iron and manganese.
