Reverse osmosis technology provides a maximum of 99.8% removal of contaminants. And this is due to an RO membrane element, which takes out all impurities, including bacteria and viruses and only allows pure water molecules to pass.

To ensure the natural taste of water we have provided a final stage of purification. It includes a coconut shell activated carbon filter, which gives especially pleasant tasting water.

Purification technology

The main Robust 1500 element is RO membrane. It provides water of perfect quality. It removes even the smallest virus particles. Only water molecules pass through it.

To extend the service life of the membrane element there are pre-purifying replacement filters provided. The sediment filter retains large particles of impurities (sand, rust) and the granular activated carbon filter removes chlorine and its compounds from the water.


DSC06901_stand by.pngSmartlight on RObust 1500 cover is not only the stylish element, it is a special indicator of operational mode, timely replacement filters and membrane element change.

Smartlight is operated with controller, which reminds you about timely maintenance to provide you the pure tasty water. 

Smartlight modes:

  1. green — filter is plugged in, operates in waiting mode

  2. blue — filtration mode

  3. yellow — time to replace the filters

  4. purple — time to replace RO-elements and filter (full service maintenance)

  5. red — breakdown, need to contact customer service


Filter RObust 1500 is intended for purification cold water only.

Replacement filter and membrane change

When developing the filter, we thought not only about the excellent taste of water, but also about providing simple installation and maintenance. Filter set included simple understandable installation and maintenance manuals. Filter will inform about timely maintenance with smartlight indicators, and we our customer service will perform it.

Pump maintenance

Pump operation requires periodic maintenance (the same as other appliances). The main operation for pump maintenance is replacing the pump diaphragm.

We recommend replacing the diaphragm every 2000 hours of its operation.

Frequency of replacement:

  • Operating time 12 hours per day (840-900 litres per day) replacement once in 5-6 months
  • Operating time 8 hours per day (560-600 litres per day) replacement once in 8-9 months
  • Operating time 4 hours per day (280-300 litres per day) replacement once in 16-17 month
