ECOSOFT 4.5X20 Polypropylene Double Cartridge, 20-5 MKM (CPV4520205ECO)

Looking for reliable protection for your plumbing system? The BB20 gradient cartridge is an advanced solution for efficient mechanical water filtration.
It is designed to remove sand, silt, rust, dust, and other solid contaminants commonly found in tap water. Thanks to its innovative multilayer structure, the cartridge captures pollutants at every stage — from large debris to fine suspended particles.

Maximum efficiency in every layer

The outer shell performs pre-filtration by trapping larger particles, reducing the load on denser inner layers. This thoughtful design extends the filter’s lifespan and ensures high filtration performance without a significant pressure drop. Even with turbid water, the system maintains consistent operation.

Benefits that speak for themselves:

▪️Up to 300,000 liters of capacity — long service life without loss of performance;
▪️3× greater dirt-holding capacity than standard polypropylene cartridges — less frequent replacement;
▪️Large filtration surface — 25% better contaminant retention thanks to uniform distribution throughout the cartridge body;
▪️Low pressure drop — comfortable usage without reduced water flow;
▪️Compact solution — replaces several standard cartridges, saving space and simplifying maintenance;
▪️Compatible with BB20 filter housings.

What do you get with this filter?

▪️Clean, clear water at every tap;
▪️Consistent water pressure in the shower and clog-free nozzles;
▪️Sanitaryware and heating equipment protected from scale and dirt;
▪️Extended lifespan of drinking water filters — fewer replacements, more convenience.

Construction and working principle

The filter element is made of cellular expanded polypropylene without an inner core — its strength is ensured by fiber sintering. This design captures contaminants within the structure without disrupting water flow. The result: crystal-clear water without sediment or particles.

Ideal for:

Large families of up to 7 people living in a house or spacious apartment. Perfect for installation in a main line to purify all incoming water throughout the home.
