The H.Preiss aquantum24 Direct Flow reverse osmosis system is a compact, high-performance system for treating tap water. Thanks to modern direct flow technology, the water is filtered directly upon dispensing and is always fresh – without intermediate storage and without waiting times.
The system combines mechanical filtration, reverse osmosis and additional physical water structuring for a special drinking water experience.
Combination package also with aquaSpin 3.8 and HELIO module
In addition to classic purification through sediment, activated carbon, and RO membrane filtration (1000 GPD), you can also equip the H.Preiss filter system as a combination package with an aquaSpin Activator 3.8 and the Helio module for additional water refinement. This creates clear, pleasant-tasting drinking water for daily use.
The aquantum24 operates with a 4-stage water treatment system that combines mechanical pre-filtration, molecular purification, and physical water treatment.
First, tap water is purified using a combined sediment and activated carbon filter. This removes coarse particles as well as chemical contaminants such as chlorine or pesticides. This is followed by the main filtration using a powerful reverse osmosis membrane, which reduces the finest dissolved substances at a molecular level.
After filtration, the water is additionally structured via the aquaSpin Activator 3.8 and then passed through the Helio module. This module aims to harmonize electromagnetic environmental influences and complements the water refinement.
Thanks to Direct-Flow technology, the water is filtered immediately upon dispensing, ensuring that fresh osmosis water is always available.
After the actual filtration, the water passes through the aquaSpin 3.8. Here, the water is physically structured, creating a hexagonal molecular structure. The goal is to give the filtered water a softer sensory quality and a particularly pleasant taste.
The integrated HELIO module is a maintenance-free element developed for modern living and working environments – for example, near WLAN routers, power lines, or electronic devices. It is based on a special combination of natural materials arranged according to a structural principle researched in Russia. The module's goal is to support a balanced environment and promote the connection between modern technology and natural harmony.
Additionally included in the combi-package:
The aquantum24 filters tap water through a combination of mechanical pre-filtration and reverse osmosis membrane (1000 GPD). This reduces particles, dissolved solids, and various chemical residues, resulting in clear and taste-neutral drinking water.
The combination of pre-filtration, activated carbon, and reverse osmosis membrane reduces, among other things:
Yes, partially.
Reverse osmosis filtration reduces dissolved minerals in the water. This can also lower the limescale content of the water, which can have a positive effect on taste and household appliances.
For water hardness above 20 °dH, an additional pre-filter for limescale is recommended.
In the first step, tap water is passed through a combined sediment and activated carbon filter. This filter stage removes coarse particles such as sand, rust, and suspended solids, as well as various chemical contaminants such as chlorine, pesticides, or heavy metals. At the same time, the activated carbon improves the smell and taste of the water and protects the subsequent filter stages.
At the heart of the system is a powerful 1000 GPD reverse osmosis membrane. The water is pressed under pressure through a semi-permeable membrane, whose pores are so fine that only water molecules can pass through. Dissolved solids, impurities, and numerous pollutants are retained and discharged via wastewater. This stage constitutes the actual main purification of the water.
After filtration, the water passes through the aquaSpin Activator 3.8. Here, the water is physically structured by a targeted swirling motion. This process is based on natural water movements, such as those found in springs or mountain streams. The aim of this stage is to improve the sensory quality of the water and create a particularly fresh, soft taste experience.
Finally, the water is guided through the Helio E-Smog Stop Module. This maintenance-free module is based on a special combination of natural materials and was developed for modern living and working environments. It is designed to harmonize electromagnetic environmental influences and complements the water refinement of the system before the water is finally drawn from the tap.
The aquantum24 filter system is installed at the water connection where you want to draw water – usually in the kitchen.
For installation, you only need:
You can generally install your aquantum24 system yourself. However, we recommend professional installation by our installation service. This ensures that everything is optimally connected – and you also receive a warranty on the installation.

We recommend changing the filter system of your aquantum24 reverse osmosis system after approx. 12 months. You only need to change the membranes every 3 years. A modern LCD display conveniently shows you the filter change and membrane status.
You can purchase the replacement filter for your aquantum24 for as little as €119. The high-quality membrane with up to 1000 GPD is available for €269.
Everything you need for your next filter change can be found here.
The filter change is uncomplicated and takes only a few minutes. Thanks to the practical bayonet lock, you don't need any tools or special prior knowledge.
With our step-by-step instructions, you can easily make the change yourself:

aquaSpin technology complements the system's filtration with physical water treatment. Through a special vortex structure, the filtered water is additionally moved and structured immediately before dispensing.
The aim of this stage is to give the water a natural dynamism and a particularly soft, fresh taste.
aquaSpin technology works with a targeted vortex movement of water. This creates a physical flow dynamic that is reminiscent of natural water movements in springs or mountain streams.
This process is intended to harmonize water and the minerals it contains. The water gains a finer structure and can therefore be perceived sensorially as particularly fresh, soft, and vibrant.
The aquaSpin 3.8 works completely without electricity or electronic components. Structuring is achieved purely through physical principles of water movement.
This makes the system maintenance-free, durable, and energy-independent. Made from high-quality materials and developed for continuous use, aquaSpin complements modern water filter systems with a sustainable form of water refinement.
According to the provider, structured water by aquaSpin can have various positive properties. These include, among others:
Note: These statements are based on the manufacturer's claims regarding water structuring and are not conclusively scientifically confirmed.
