NIKKEN Water Filter

the NIKKEN PiMag Waterfall has been specially developed to enrich the water with minerals, give it a basic pH between 8.5 and 9.5 and reduce the oxidation-reduction potential (ORP). The filtration system made of recyclable and biodegradable materials is environmentally friendly and helps to reduce landfill waste.

  • PIMAG ® Water Technology
  • Gravity principle
  • Multi-level filtering
  • Constant quality
  • Resistant materials that do not leave chemical residues in the water

The PIMAG ® Waterfall manufactures pure, Filtered PiMag ® water without water connection and electricity..

Multi-stage filtration

Depending on the water supply and the nature of the water pipes, tap water can have traces of numerous chemicals such as chlorine, as well as disinfection by-products, sediments, heavy metals and pesticides. However, the Nikken water systems allow you to turn your normal tap water into pure PiMag® water. The first stage is a pre-filter that traps larger particles in the water. Then an activated carbon filter filters out microscopic particles. The next stage is for mineralization and alkalinization, while the following company’s redox process continues the purification of the water. The oxidation reduction potential (ORP) is reduced and water is created, which helps to neutralize harmful free radicals that can harm our body. The PiMag ® water then passes through a deposit of mineral rock and a magnetic field before it finally enters your glass.

Highest quality standards

All Nikken PiMag® water systems meet the highest material standards – the building materials do not release chemicals into the water and are free of bisphenol A and other estrogen-like substances.

The water contaminants and other substances that can be reduced by this product for water treatment are not necessarily in your water. Only locally treated water or water derived from a microbiologically safe source should be used.

Fill only with cold water. This product contains silver to inhibit bacterial growth in the filter, thereby extending the life of the filter. Silver has a very low toxicity to humans, but is highly toxic to fish and other aquatic life. This product is specifically designed to reduce undesirable taste, smell, discoloration and the content of chlorine, chloramines, volatile organic compounds and mercury in municipally treated tap water.

Where is the 1200 gauss magnet positioned and what is its purpose? In your documents it states that this decreases agglomeration.

The magnet is located in the blue tube inside the bottom tank where the water flows through to the tap. Water molecules are dipolar and tend to attract each other. Magnets affect the bonding angle between the hydrogen and oxygen atoms in the water molecule. This in turn reduces the molecule cluster groups to become smaller and this is suggested to increase absorption. Agglomeration is defined as the gathering of mass and as the magnet reduces this mass into smaller clusters it decreases agglomeration.

What is ion exchange resin?

Ion-exchange resin is used in water purification products and is there to help remove heavy metals while also adding ions such as sodium and potassium that help towards alkaline water.

In the materials it is mentioned that the first layer of the filter contains carbon and alkaline materials. What are these alkaline materials?

The alkalizing materials will be a number of minerals that promote alkaline water. We do not release a full specification to customers due to proprietary requirements safeguarding our products from being copied.

The second layer contains clay granules what is their role? It also contains bio silver and minerals. What are these minerals?

The second layer of our filter contains various elements that help filter contaminants while releasing minerals that help increase pH. We do not release a full specification to customers due to proprietary requirements safeguarding our products from being copied.

The third layer contains fine silica and KDF. What is KDF? The golden layer at the bottom is this KDF or silica sand?

KDF is (Kinetic Degradation Fluxion) material that again assists in the reduction of contaminants. This will be the gold looking material

Through the filtration process, the potential of oxidizing gets low. How does this work?

ORP (Oxidation Reduction Potential) is a measure of a water system’s capacity to either release or gain electrons in chemical reactions. ORP is measured in millivolts and indicates if a solution is oxidising or deoxidising. The higher the positive number the more oxidising the solution is and therefore a lower positive number or a negative number will denote that the solution is deoxidising and contains antioxidants. With the reduction of oxidizing chemicals such as chlorine the ORP levels will lower and therefore show that the water has more antioxidants.

You create alkaline water. What is the PH?

The PiMag Waterfall has been tested in laboratory conditions and has shown to increase the pH from tap water of 7 to 7.5pH to between 8.5 and 9.5pH. Each country and area may differ depending on the source water used.

Is there a major difference in the 1 micron filtration level of the Waterfall compared to the 0.02 micron level in the Maxi?

The difference is very small. The PiMag Waterfall has been created to provide alkaline water with a low ORP. To obtain both these aspects you have to be able to filter contaminants and add minerals. The filtration process has been rated, in a laboratory, at 1 micron which will filter a very high percentage of contaminants found in tap water. Our test results, found on MyNikken, prove that the Waterfall matches or exceeds our current water systems in filtering contaminants and adding minerals.

The change period for the filters is 900 l, for the other systems is 2200 l. Have they got a higher life span?

The filter life span on the PiMag Waterfall has been rated at 900 litres based on the continued filtration levels required to meet specific contaminant reduction levels. The filter has a different composition to our other filters and therefore cannot be compared like for like. Through extended testing we have increased the timescale on replacement parts.

Filter change times, every 900 l or every 3 months. If I used it 10 times only in 3 months do I have to change the filter?

You should be promoting the system as a product that is to be used on a daily basis. You will not be receiving the full benefits of the system if you only use in short periods. Replacement part times are based on a constant usage.

What is the difference between the Maxi stones and the Waterfall stones and can I use my Maxi stones in the Waterfall?cteria?

The Waterfall stones have slightly different mineral elements to the Maxi stones and the system has only been tested based on these stones. We cannot guarantee any results for the Waterfall based on using Maxi stones

Sometimes my filter leaks water down the side and into the bottom tank, how can I stop this?

You should first check that the filter is positioned correctly in the top tank and pushed all the way down the hole so it sits on the ledge. It can happen that the filter is not level and the water leaks on one side. A good option is to remove the top tank while the filter is in place and grab the bottom of the filter while using your thumbs to push against the bottom of the tank. This enables you to manoeuvre the filter into place and to make sure it is level. Once you have done this you can fill the top tank with a litre of water to test that the leak has stopped. Another option is to remove the silicone seal that sits around the top of the filter just below the cap and to then replace it. This may help to remove any small dents that are allowing the water to leak.
