BWT service

Bestmax, AQA drink and mechanical filters are changed by litre capacity or pressure drop, not “once a year”. The Bestmax reference is 8 °dKH carbonate hardness: in Almaty, Astana and other hard-water regions capacity is shorter. Send the model and city — we will suggest a replacement interval.

With a test strip, a lab, or utility data. For Perla softeners and Bestmax cartridges, carbonate hardness (°dKH) matters. Send your city and task — we will advise based on typical regional water.

The warranty applies when installed and used as instructed. In Kazakhstan, service is through BWT Kazakhstan: inquiry, visit, consumable replacement. We confirm the term for a specific model in the quotation.

Yes. Household filters, HoReCa and industrial plants — on request in Almaty and with visits to other cities. A maintenance contract is convenient for regular cartridge changes.

Popular sizes are often on Kaspi. If the size is missing, we supply it via the BWT Kazakhstan office in Almaty and agree a lead time.
