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.

What does the under-sink filter reduce?

It reduces bacteria, chlorine, heavy metals, large particles, and more impurities — while keeping healthy minerals like calcium and magnesium.

Is the system certified?

Yes, it's certified by IAPMO R&T to NSF/ANSI 42 & 372 standards for contaminant reduction and low lead.

Is installation difficult?

Not at all. It's a quick DIY setup with all parts included — no drilling needed.

What is the housing made of?

Food-grade stainless steel. It's corrosion-resistant, leak-proof, and built to last.

How fast can you get pure water?

1.5 GPM — fast enough to fill a 6oz cup in less than 2 seconds.
