Water filtration is important
Sanitary water is periodically subjected to strict controls and, in order to be distributed to public or private users, it must comply with rigid parameters.
Nevertheless, the water we use in our daily lives is never completely pure, and it is strongly recommended to adopt certain solutions to improve its properties, prevent the formation of limescale and scale, and protect boilers, appliances, and heating systems from damage and malfunction.
The ideal solution to improve water quality, whether it is rainwater, well water, or, as is more common, water from the distribution network, is filtration.
But which filter to choose?
Ecoterm Water Solutions offers a wide range of filtration systems to meet the needs of every type of system and the expectations of the end user.
Each type of filter designed by Ecoterm Water Solutions has its own cartridge cleaning system, varying levels of maintenance complexity, and may be suitable for water of varying levels of impurity.
Let's take a closer look at them below.
Washable cartridge filter
Cartridge cleaning is done manually by simply disassembling the filter bowl.
They are robust and highly performing filters for low to medium dirty water that require a bit more complex maintenance compared to other ranges due to the lack of an automatic or semi-automatic cleaning system.
The models of cartridge cleaning filters by Ecoterm Water Solutions are:
- Cosmo 1BL PP
- Cosmo 1BL AI
- Cosmo 1B Simplex
- Cosmo 1B

Rinse cleaning filter
The cartridge cleaning is done through a backwash process using a drain valve.
By opening the drain valve, the incoming water pressure cleans the cartridge externally, removing sediments and directing the dirt to the drain located at the bottom of the filter.
These filters are robust and highly efficient, suitable for moderately dirty water, and require standard maintenance.
The backwash cleaning allows the filtration system to stay clean without the need to physically disassemble the filter frequently, only for extraordinary maintenance.
The backwash cleaning filter models by Ecoterm Water Solutions are:
- Cosmo 1BVL PP
- Cosmo 1BVL AI
- Cosmo 1BV Simplex
- Cosmo 1BV

Semi-automatic brush cleaning filter
The cleaning is done through the manual brushing of the cartridge.
By rotating the knob on the top of the filter, brushes are activated that scrape any solid residues filtered from the glass, which are then directed and expelled simultaneously towards the drain.
These filters are robust and highly efficient for dirty water, requiring standard maintenance.
The manual cartridge brushing cleaning allows the filtration system to remain clean without the need to physically disassemble the filter.
The semi-automatic cleaning filter models by Ecoterm Water Solutions are:
- Cosmo 2
- Cosmo 2B
- Cosmo 2B Maxi

Self-cleaning filters with Wasserjet technology
The cartridge cleaning is carried out thanks to Ecoterm Water Solutions' new Wasserjet technology.
The washing process occurs in counterflow: by opening the drain valve, the pressure from the incoming water causes the filter cartridge to drop, allowing for internal cleaning. The water flow, acting from the inside out of the cartridge, removes impurities much more effectively, which are then directed and expelled through the drain located at the bottom of the filter.
These filters are robust and highly efficient for very dirty water and require minimal maintenance, as the counterflow cleaning promotes optimal and highly effective cleaning of the filtration system without the need to physically disassemble the filter.
The self-cleaning filters with Wasserjet technology from Ecoterm Water Solutions are:
- Cosmo 1BVL AI Wasserjet
- Cosmo 1BV Simplex Wasserjet
- Cosmo 1BV Wasserjet

Conclusion
All of the water filtration systems by Ecoterm Water Solutions perform extraordinarily well thanks to the technology and high-quality, durable materials they are made of.
