Full-scenario water treatment solutions provider

For a 50-person office, bottled water annual costs are approximately 1.5-2 ten thousand yuan (including water dispenser rental, deposit, and ongoing water purchases). In contrast, once the direct drinking water system is installed, the annual operating cost is only about 3000-5000 yuan (electricity + filter replacement), with ROI typically achieved in 1-2 years. Long-term use can save over 60% in expenses. Additionally, direct drinking water is produced on demand, eliminating the risk of secondary contamination from stored bottled water.

Buyuan offers a 7-star service guarantee: 30-minute phone response, 4-hour engineer on-site arrival, and 8-hour fault resolution. If unresolved within the timeframe, we provide a free backup unit to ensure uninterrupted water supply. We offer nationwide warranty coverage with lifetime maintenance, serving over 3000 districts and counties across China. All service commitments are legally binding in our contracts; you have the right to hold us accountable if we fail to meet them.

Filter replacement intervals vary by water quality and usage: PP cotton filters 3-6 months, activated carbon filters 6-12 months, and RO membranes 2-3 years. We intelligently monitor filter status and proactively notify you when replacements are needed. Leveraging our direct supply chain with the manufacturer, filter prices are 30%-50% lower than market rates, ensuring genuine products are always in stock. For a typical office drinking water dispenser, annual filter costs range from 500 to 800 yuan.

Depends on the site: Simple setups (e.g., office drinking water stations) can be installed and tested the same day. Complex projects (e.g., building-wide piped drinking water or factory pure water systems) typically take 3–7 days. We'll survey the site in advance, design a minimal-impact renovation plan to avoid disrupting your operations, and ensure all work meets standards with full site cleanup upon completion.

All our equipment is certified by 8 major international authorities, including NSF, TUV, and SGS. After installation, we conduct water quality testing and provide a report to ensure the produced water meets or exceeds China's "Standards for Drinking Water Quality" (GB5749-2006). For specialized applications such as medical or industrial use, we can arrange third-party inspection reports upon request. During operation, we perform regular inspections and document water quality data.
