Year set of filters Aqualine 12 - alkaline

This annual set includes a ceramic filter, a pH neutral multi-step filter and a pH ring for the Aqualine 12 glass and abs water filters pictured on this page.

If you prefer to drink pH neutral water click here.

Also included with this alkaline combination is a pH ring that increases the pH of the filtered water by 1 to 1.5 points. This makes slightly alkaline/basic water with a pH between 8.5 and 9.5. The final pH always depends on the pH of your tap water.

Replace the ceramic filter and multi-step filter annually and in any case after 2,000 liters of water (if you filter more than 6 liters of water daily on average.) Replace the mineral stones every 3 years.

This filter fits all Aqualine/AQV/AquaVit 12 models. It also fits in the KS 951, KS 971, KS 966 P (water cooler) the Aquavit 12, the Biovit 200 and all Keosan and Cosan 12 liter models. Furthermore, this filter fits in several Nikken piMag systems.

This new generation multi-step filter filters up to 99.9% of pollutants from water.

Which Aqualine water filter is right for you?

All Aqualine water filtration systems work the same way.

  • Comprehensive filtration using various filters and different
    filter media.
  • Adding minerals and trace elements using Elvan mineral stones.
  • Vitalization of water during tapping (according to the Victor Schauberger principle)
  • If desired, the pH of the water can be raised to make it slightly alkaline.

All Aqualine water filters filter approximately 1.5 liters per hour. Because the water is filtered slowly
, the filter media can remove more contaminants from the water.

The flow rate of 1.5 liters per hour is an important factor to consider when making your choice. If you buy a water filter with a small tank capacity, you’ll have to refill it more often
compared to a larger water filter.

Another important factor to consider when making your choice is the size of the Aqualine water filter. Will the system fit in the spot you have in mind (for example, under a cabinet)? With the Aqualine 5, 12, and 18 models, the white base can be removed. This allows the tank that collects the water to be placed on a shelf or raised platform, for example.

The capacity of the collection tank (where the filtered water is collected) is based on an empty tank. This tank contains a multi-stage filter, mineral stones, and possibly a pH ring. Therefore, subtract 1.5 liters from the tank capacity to determine
how much water you can draw from the system at one time.

Which Aqualine is right for you?

Aqualine 5

  • Suitable for 1–2 people
  • The capacity of the empty tank is 5 liters
  • Perfect for drinking water and making coffee or tea

Aqualine 12

  • Suitable for 2–3 people
  • The empty tank has a capacity of 8 liters
  • Also suitable for 1–2 people who, in addition to drinking water, coffee, and tea, also want to use the water for cooking or simply want to have a bit more water on hand.

Aqualine 18

  • Suitable for 4 or more people
  • The capacity of the empty tank is 11.7 liters
  • Ideal for large households, a medical practice, or a small office

Aqualine Neos

  • Suitable for 4 or more people
  • The capacity of the empty tank is 9.8 liters
  • Ideal for large households, a medical practice, or a small office
  • Unique square design

Choosing the material

The Aqualine 5, 12, and Neos are available with either an ABS (plastic) or glass
sump tank. The Aqualine 18 is available only with a glass tank.

ABS and polypropylene are the two plastics known to be food-safe. They do not impart any taste. They also do not release BPA, BPS, BPF, BPFAF, BPAP, or any toxic substances.

The glass tanks are handcrafted in South Korea. This results in a price difference between the ABS and glass versions.

The material used does not affect the quality of the filtered water.

Choose between pH-neutral or alkaline (Redox)

By default, the water is adjusted to a pH of 7.2–7.4 after the filtration process.

Optionally, the water can be made slightly alkaline using the pH ring (for the Aqualine 5, 12, 18) or the Redox filter (for the Neos). This raises the pH level by 1–1.5 pH units. The water does not become alkaline immediately after filtering. The contents of the pH ring and the substances from the Redox filter need time to dissolve in the water. This process takes several hours.

People who lead a healthy lifestyle and do not take acid-forming medications
generally do not need alkaline water.

Alkaline water is not recommended for children under 4 years of age.
