About NU Aqua

Editorially researched & verified

NU Aqua Systems is an online retailer specializing in professional-grade water filtration and reverse osmosis (RO) systems designed for home use. Operating at nuaquasystems.com, the brand offers a comprehensive lineup that includes under-sink RO systems, countertop reverse osmosis units, tankless systems, whole-house filtration, shower filters, and inline refrigerator filters — making it a one-stop shop for household water quality needs.

The NU Aqua Platinum 100 GPD RO System is the brand's bestselling product, marketed as the most affordable option in its category with optional alkaline and UV filter upgrades, as well as a booster pump add-on for low-pressure homes. The Tankless 600 GPD Efficiency Series delivers high-output filtration with a 2:1 pure-to-waste ratio, alkaline and UV filter compatibility, and built-in filter replacement reminders. For those without under-sink space, the Countertop RO System offers hot and ambient water dispensing with zero installation required and a digital display for filter change alerts.

Aquarium enthusiasts are catered to with the Reef Series 4-Stage RODI System, which consistently achieves 0 TDS output using premium deionization media — critical for sensitive reef tank environments. Across all major categories, NU Aqua currently advertises 15% OFF sitewide promotions, and a VIP Club email subscription offers exclusive member discounts and content to registered shoppers.

Customer support is accessible via phone at 1-888-621-0460 and by email at support@nuaquasystems.com. The site also provides a 30-second product quiz to help buyers identify the right filtration system for their home, along with a Learning Center and FAQ section for self-service education on water filtration topics.

NU Aqua maintains an active social media presence on Instagram, Facebook, TikTok, and YouTube, and its Filter Club subscription service allows customers to automate replacement filter deliveries. Whether you're looking for a budget-friendly under-sink RO unit, a high-capacity tankless system, or a portable countertop solution, NU Aqua provides tiered options designed to meet varied household water filtration needs.
