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.

Contact Us

Is the water from this unit really safe to drink directly?

It uses a precise 0.0001μm RO membrane and LED function to reduce harmful substances like TDS, PFOA, PFOS, nitrate, fluoride,lead, and more. The water is tested by a third-party lab, so you can trust it's pure and safe.

Where does the waste water go?

The waste water is safely directed into a dedicated 50oz waste water tank. Our system keeps the tap water and waste water in 100% separate tanks. This eliminates any risk of the waste water flowing back. You can then easily reuse the collected waste water for watering plants or cleaning, which helps you save water and money.

Can I get hot water instantly for coffee, tea, and cooking?

Absolutely! This isn't just a water filter; it's an instant hot water dispenser. With 5 preset temperature settings, you can get the perfect temperature in seconds: room-temp for daily drinking, 113°F for baby formula, 149°F for tea, 185°F for coffee, and 203°F for oatmeal.

Is the water pitcher safe and easy to handle?

Yes. The included 40oz BPA-free glass pitcher is not only safe but also detachable and easy to clean. It's designed for convenience — use it to store pure water in your refrigerator, pour water for cooking, or easily hydrate your pets. The glass material ensures no plastic taste and long-lasting freshness.

Is the installation complicated?

This water filtration system only requires filling the water tank and plugging it in to start using it. It's perfect for renters, offices, and RVs. You can enjoy pure drinking water anywhere.
