Frequently asked questions
Quick answers to the most common questions about water treatment in Cyprus.
Why do standard water filters not work well in Cyprus?
Most standard carbon filters remove chlorine and sediment but do not remove dissolved minerals. In Cyprus, mineral-heavy water can still leave scale and a heavy taste after simple filtration.
Do I really need reverse osmosis in Cyprus?
Reverse osmosis is useful when the goal is to reduce dissolved solids in drinking water. Whether it is the right choice depends on source-water measurements and the problem you want to solve.
What is the difference between a water softener and a drinking water filter?
A softener treats hardness for the whole home. A drinking-water filter such as RO is normally installed at the kitchen sink and focuses on water for drinking and cooking.
Why does limescale build up so quickly in Cyprus homes?
Calcium and magnesium remain behind when hard water is heated or evaporates, creating deposits on heating elements, taps and glass.
How can I check if my current water filter is actually working?
Compare source and filtered water with appropriate measurements, review the service history and test the system if performance is uncertain.
How often should water filter cartridges be replaced?
Many sediment and carbon cartridges are serviced every 6–12 months, while RO membranes usually last longer. The exact schedule depends on the model, usage and source water.
How often should salt be added to a water softener?
Salt usage depends on hardness, water consumption and regeneration settings. Check the brine tank regularly rather than relying on a fixed calendar.
Tank vs Tankless Reverse Osmosis Systems — What’s the Difference?
Tank systems store purified water; direct-flow systems produce it on demand with higher-capacity membranes. Space, flow and household usage determine which design fits best.
How do I choose the right water filtration system for my home?
Start with the actual problem—drinking water, limescale or both—then use water measurements, household size and available space to narrow the choice.
