Ecosoft CROSS Max — Tankless Direct-Flow RO Filter
The CROSS Max by Ecosoft is a high-performance tankless direct-flow reverse osmosis filter (800 GPD, 2 L/min), ultra-compact, with cartridge replacement indicator and automatic flushing. Ideal for pure under-sink water.
The CROSS Max by Ecosoft is a next-generation direct-flow reverse osmosis filter, designed for under-sink installation in apartments and houses. Its ultra-compact tankless design fits easily into standard kitchen cabinets while delivering a high flow rate of 2 L/min of purified water.
Why choose the CROSS Max?
The CROSS Max purifies municipal tap water using a four-stage reverse osmosis process. The filter reduces the content of PFAS, mineral impurities and other contaminants, while improving the taste and odor of water. Filtration includes a prefilter that removes sediment and chlorine, followed by an RO membrane with an integrated activated carbon post-filter to provide pure water with a fresh taste.
Key Features
High flow rate (800 GPD) — the filter delivers up to 2 L/min of purified water, i.e. 120 L/h.
Ultra-compact tankless design — no storage tank, saves valuable space under the sink. Dimensions: only 304 × 198 × 191 mm for 6 kg.
67% recovery rate — among the best on the market, less water rejection.
Cartridge replacement indicator — the intuitive display shows the filtration mode and remaining cartridge life. It notifies you every 600 liters and alerts you 200 liters before end of life.
Automatic flushing — the filter performs automatic flushing to reduce natural diffusion during idle periods and maintain stable water quality.
Leak sensor — automatic shut-off of the device when a leak is detected.
Quick and tool-free installation — simple setup, cartridge replacement in seconds.
