FAQ
Curious about how the RO filter works? Our FAQ section covers everything from filter lifespan to installation tips for clean, pure water every day.
How easy is installation and filter replacement?
You can set up the system in 30 minutes — no tools or plumbers needed, and swap filters in just two seconds with the lift-and-pull design.
Do I need a storage tank?
No. The tankless design saves under-sink space and fits seamlessly into any modern kitchen, avoiding the bulk of traditional RO tanks.
What is the smart LED faucet?
The 360° rotating faucet displays real-time TDS levels on its LED screen and beeps with light alerts whenever it's time to replace your filters.
What makes the WD-D6-B's filtration so effective?
The WD-D6-B features six stages of filtration — including a precise RO membrane, filtering out impurities larger than 0.0001μm from your drinking water.
