Ultra-compact reverse osmosis RObust CROSS Solo without tank
The RObust CROSS Solo from Ecosoft is a compact and powerful kitchen water filter with direct flow that removes up to 99% of contaminants, including viruses, bacteria, heavy metals, organic substances, and other impurities. It provides instant access to clean water while optimizing water consumption thanks to a technology with a 50% recovery rate.
It is designed without an integrated water tank, which significantly saves space under the sink while ensuring access to freshly filtered water exactly when you need it. Thanks to its design, smart features, and ease of use, it is an ideal choice for smaller households as well. Using filtered water in appliances such as coffee makers or electric kettles reduces the buildup of limescale, contributing to their longer lifespan and reliable operation.
Ideal solution for anyone looking for a tankless drinking water filter that saves space and time.
Advantages and main features of CROSS Solo reverse osmosis
- Effective and fast water filtration - Thanks to direct flow technology, you can get a glass of clean water in just 10 seconds.

Reverse Osmosis Filtration Process CROSS Solo
DOUBLE FILTRATION TECHNOLOGY IN ONE
1. Reverse osmosis filtration
- High-efficiency (500 GPD) reverse osmosis membrane that removes 99% of contaminants from water, such as microorganisms, dissolved salts, heavy metals, and harmful substances.
- Effectively reduces the content of dissolved solids, ensuring clean and safe water.
2. Carbon post-filtration
- Removes odors and organic impurities and improves taste using high-quality carbon from coconut shells.
- It provides fresh, clean water suitable for drinking and household use.
Recommended operational warning
After a long break in using the system, such as in the morning, we recommend discarding the first two glasses of water or using them, for example, to water plants. The reason is that during the overnight break in using the system, there may be a slight backflow (diffusion) through the membrane, which can temporarily affect the quality of the pre-filtered water.
