FAQ

Curious about how the RO works? Our FAQ section covers everything from filter lifespan to installation tips for clean, pure water every day.

Is the water really safe and clean enough to drink directly?

Yes. The WD-M6SL reverse osmosis water filter features an 8-stage filtration system with a 0.0001μm RO membrane and LED Function. It effectively reduces TDS*, PFOA*, PFOS*, fluoride*, heavy metals like lead* and arsenic*, and more* — providing clean, safe drinking water you can trust every day.

*Claims based on theoretical evaluation by our internal R&D laboratory.

Will the water taste too flat after RO filtration?

Unlike typical RO systems, this unit adds beneficial minerals such as K⁺*, Ca²⁺*, Na⁺*, and Mg²⁺* back into the water. This creates a balanced, slightly alkaline taste that enhances flavor — perfect for drinking, cooking, coffee, and tea.

*Claims based on theoretical evaluation by our internal R&D laboratory.

Does this system waste a lot of water?

This system is designed with a 3:1 pure-to-drain water ratio, making it more efficient than many traditional RO systems. It also separates tap water and waste water into different tanks, and the waste water can be reused for cleaning, watering plants, or other household tasks.

Is it difficult to install or use?

Not at all. This is a installation-free countertop RO system. Simply fill the tank, plug it in, and start using it — no plumbing or drilling required. It’s perfect for apartments, offices, and even RV use. The smart touch panel and preset volume and temp options make daily use easy and intuitive.

How do I monitor the filter and get support if needed?

The system includes a filter life indicator to keep you informed when it’s time for replacement. It also features NFC one-tap support, just tap your phone to access installation guides, FAQs, and customer support instantly, making maintenance simple and stress-free.
