Reverse osmosis systems

Reverse osmosis systems are drinking water filters that use an osmotic membrane to thoroughly purify tap water. Reverse osmosis technology helps reduce many dissolved contaminants, improve the taste and smell of water, and prepare it for everyday drinking, cooking, and use in coffee machines. In this category, you will find complete RO filters for homes, apartments, and offices, including systems with mineralisation and filter cartridges.

How to choose a reverse osmosis filter?

Which RO filter for a family of 3–4?

For a family of 3–4, an RO filter with higher output and convenient operation is a sensible choice. If space under the sink is limited, a tankless RO system may be practical. It dispenses water faster and is convenient for drinking, cooking, the kettle and the coffee machine.

When should you choose an RO filter with remineralization?

An RO filter with remineralization is a good choice when water taste matters as well as thorough purification. A remineralizing or REDOX cartridge is especially useful for people who drink directly from the filtered-water tap and want to reduce bottled-water use.

When does the least expensive reverse osmosis filter make sense?

An economical RO filter can work well with lower water demand and basic purification needs. For a larger household, high demand or limited space under the sink, a higher-performance model may offer better everyday comfort than choosing on price alone.

Frequently asked questions about RO filters

Is a tankless reverse osmosis filter better?

A tankless RO filter is convenient when saving space and fast dispensing matter. It is not always necessary, but it can significantly improve comfort for a larger household and frequent use.

How often should RO filter cartridges be replaced?

Replacement intervals depend on the model, water quality and usage. Pre-filters are usually replaced periodically every few months, while the membrane lasts much longer. Always check the schedule for the selected product.

Do I need a remineralizer in an RO filter?

A remineralizer is optional, but it can improve the taste of water after reverse osmosis. It is often chosen by people who drink directly from the filtered-water tap.

Can an RO filter be used with mains water?

Yes. Reverse osmosis filters are commonly installed for mains water in the kitchen. They help improve the taste, odour and quality of water used for drinking and cooking.
