FAQ

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

How does the dual-flow feature benefit me?

You can switch instantly between standard RO-purified water for everyday drinking and an alkaline stream that adds beneficial minerals, perfect for coffee, tea, or anyone who prefers a smoother taste profile.

Does the system keep water hygienic after filtration?

Yes. Each water line has its own UV LED sterilizer that continuously disinfects the water as it leaves the filter, safeguarding freshness all the way to the faucet.

Does it require a storage tank?

No. The compact, tankless design prevents secondary contamination and frees up about 70 % more under-sink space compared with tank-based RO systems.

Is installation complicated?

No! The tank-free design make under-sink installation straightforward for most homeowners — no bulky tank to position or maintain.

Will the alkaline stream affect beverage flavor?

Yes — positively. The mineral-enhanced line can improve the taste and aroma of coffee, tea, and cooking water while still delivering contaminant-reduced purity.
