Cartridge filter or backwash filter – which is more environmentally friendly?

It is sometimes said that cartridge filters are more environmentally friendly than backwash protective filters. The reason given is that water is consumed during backwashing.

However, if you make a thorough comparison, you will quickly see that this calculation does not work.

Tens of litres of water are used to manufacture and transport a replaceable filter element, including foil packaging and cardboard – many times more than what flows into the sewage system during backwashing. Not to mention the energy required for production and transport.

In addition, a small mountain of waste accumulates with every filter change. And this at least twice a year, because filter cartridges must be replaced at least every six months for hygienic reasons (according to EN 806-5, A).
