RO7 Platinum Water ULTRA7 reverse osmosis water filter

7-stage reverse osmosis filter for home use

Platinum Wasser ULTRA7 is a household osmotic filter designed for drinking water treatment. Its construction was developed for everyday kitchen use wherever stable water quality and effective reduction of typical contaminants present in tap water matter.

This is a solution for people who expect not only precise purification from a filtration system, but also improved utility properties of water. In addition to proper filtration, the system also uses a taste and odor improvement stage, a mineralization stage, and an ionizing cartridge.

How the ULTRA7 system works – complete 7-stage filtration

The RO7 Platinum Wasser ULTRA7 system uses seven successive stages of water purification and treatment. Each stage performs a specific function and supports the operation of the following cartridges, making the entire process multi-level and precise.

1. Stage I – 20-micron foam cartridge

   The first stage is responsible for retaining all kinds of mechanical impurities such as sand, rust, and other sediments. This is pre-filtration that protects the subsequent system components and improves the operating conditions of the following cartridges.

2. Stage II – carbon cartridge

   The second stage is intended for filtering chlorine, chlorine derivatives, lead, toxic heavy metals, and removing organic compounds and mechanical impurities down to 20 microns. This stage also helps reduce undesirable organoleptic characteristics of the water.

3. Stage III – 5-micron foam cartridge

   The third stage again retains mechanical impurities such as sand, rust, and other sediments, but with greater precision. As a result, the water reaching the membrane is better prepared for further filtration.

4. Stage IV – osmotic membrane

   The osmotic membrane consists of many layers wound around a perforated central core placed inside. It retains 96–99% of dissolved organic and inorganic contaminants in water, heavy metals, and some bacteria and viruses not smaller than 0.001 micron.

   The contaminants are separated and discharged into the sewage system, while thoroughly purified water passes through openings into the central core and, under pressure, flows out of the membrane. This is the key stage on which the effectiveness of reverse osmosis technology is based.

5. Stage V – inline carbon cartridge

   The fifth stage uses a high-quality bed made from coconut shell carbon. The role of this cartridge is to improve the taste and odor of the water, making it more pleasant for everyday drinking and for preparing beverages and meals.

6. Stage VI – inline mineralizing cartridge

   Reverse osmosis removes 96–99% of contaminants and minerals, which is why the system is equipped with the L-MIN mineralizer. This cartridge enriches the water with lost minerals such as calcium, magnesium, sodium, and potassium.

7. Stage VII – ionizing cartridge (alkalizer)

   After flowing through the cartridge, the water retains freshness for longer, neutralizes the pH of body fluids, and is an excellent scavenger of free radicals responsible for the development of cancer diseases. Additionally, such water becomes more easily absorbed by the body.

   Water treated by the alkalizing cartridge delivers much more oxygen to the body and helps cleanse the body of toxins.

Key user benefits

Set contents and system design

The set includes a 75 GPD membrane with a capacity of 280 l/24 h. The system operates based on 3 filter housings, quick connectors, and a 3/8" water connection. The set also includes a tank with a total capacity of 12 l, which, depending on the pressure, can store approximately 8 l of clean water.

What applications is this system suitable for?

RO7 Platinum Wasser ULTRA7 works well as a kitchen water filter for people who want to use water intended for drinking, preparing tea, coffee, soups, and everyday cooking. Thanks to multi-stage water treatment, the system helps achieve stable utility water quality without the need to reach for bottled water.

It is a practical choice for users looking for a solution combining an osmotic filter, taste and odor improvement, mineralization, and an alkalization stage in one device.
