Read articleFrequently asked questions
Why do you need a water filter in Latvia?
Latvian water is mostly moderately hard (10–14 °dH), so limescale damages appliances and affects taste. Cities add chlorine, rural areas add iron and bacteria. Filtration restores water quality to natural values, without buying bottled water.
Which is better, a softener or reverse osmosis?
They solve different tasks. A softener treats all the water in the house and protects appliances from limescale. Reverse osmosis prepares drinking water in the kitchen. A complete solution often needs both, and we install them in a single visit.
Is reverse osmosis water too pure and stripped of minerals?
That is a common myth. Our RO-7 and RO-8 Premium systems include a remineralisation stage that adds the minerals the water needs back in. The result is clean, balanced water with a natural taste, not distilled water.
How long does installation take?
We install an under-sink RO system in 2–4 hours and a softener in the utility room in 4–6 hours. A full set of RO, softener and UV is installed in a single working day.
How often do filters need changing, and how do I keep track?
Pre-filters every 6–12 months, the membrane every 2–3 years, post-filters every 12–18 months. We keep track of your system's running time, remind you before a change is due and deliver original cartridges.
Do you work with wells and boreholes?
Yes. For private homes with their own water source we offer mechanical pre-filtration, iron removal and VIQUA UV disinfection, which destroys bacteria and microorganisms without chemicals.
Do you offer solutions for offices and HoReCa?
Yes. For offices, cafés and hotels we offer dispensers with hot, cold and sparkling water that connect to the mains. Rental and purchase options are available with full service and filter changes.
How much does a water filter system cost?
The price depends on the system you choose, your water quality and the installation conditions. That is why we do not quote a single figure for everyone: after a free consultation and water analysis we prepare a precise quote with no hidden costs. You pay exactly for the solution your home actually needs.
