Pure, Reliable Water Right at Your Tap

Enjoy ultra-fresh, great tasting drinking water directly from your kitchen tap for cooking, coffee, tea, and ice. The APEC Water RO-90 is designed to deliver high-quality filtration with less hassle, helping you save time and money while supporting healthier daily hydration. This premium 5-stage system is WQA Gold Seal tested, offering confidence in impurity removal without compromising on performance or quiet operation.

Premium filtration you can trust

The RO-90 uses a thoughtfully arranged five-stage process with USA-made components to target a wide range of contaminants and tastes. Here’s how it works at a glance:

• Stage 1 — High-grade sediment filter removes dirt, particles, and rust to protect the membrane.
• Stages 2 & 3 — Premium extruded carbon blocks reduce chlorine, tastes, odors, cloudiness, and colors; also tackle VOCs.
• Stage 4 — FILMTEC TFC RO membrane delivers high rejection of dissolved solids and impurities.
• Stage 5 — Advanced coconut shell carbon removes any residual taste from stored water.

Compared to smaller all-in-one filters, the RO-90 delivers 2X impurity removing capacity, meaning fewer filter changes while maintaining strong filtration performance. It’s designed for reliable, long-term use with a focus on safety and purity.

Design, durability, and ease of use

Beyond filtration, the RO-90 emphasizes practical Home-Ready design. Features include a 100% lead-free designer faucet, durable JG Quick Connect fittings for clean, secure connections, and a leak-resistant build that aims to minimize noise and interruptions. The system is equipped to handle up to 85 psi feed water pressure, making it compatible with many standard home water lines. Replacing filters is intuitive, supported by clearly labeled parts to simplify maintenance.

• Large capacity filters offer longer service life between changes.
• Lead-free faucet and high-grade tubing for safe, impurity-free water delivery.
• Easy-to-identify filter replacements and a design focused on leak prevention and reliability.
• Lifetime support and 2-year manufacturer coverage with registration.

The RO-90 sits neatly under most sinks and stores purified water efficiently. Tank dimensions are compact at 11 inches by 11 inches by 15 inches, helping you maximize cabinet space while ensuring a steady supply for cooking, beverages, and ice. With the proven filtration stack and USA-made components, you can count on consistent performance across daily tasks without heavy maintenance.

This system has earned industry recognition through the WQA Gold Seal and its commitment to high impurity removal rates, including substances like chlorine, lead, fluoride, arsenic, chromium, and other common contaminants.
