USA Tech Support Tankless 400 GPD Reverse Osmosis System - Under Sink Filtration

Usage & Benefits

Top Tier Filtration Performance

The PD400 under sink reverse osmosis water filtration system offers top-tier filtration, employing a composite pre-filter and RO membrane with unmatched precision of 0.0001 micron. This system implements a deep 5-stage filtration process, ensuring the removal of over 1,000 types of contaminants, including lead, chlorine, fluoride, heavy metals, chloramine, VOCs, TDS, limescale, arsenic, and asbestos. Additionally, the system includes a TDS meter, enabling you to monitor your water quality.

Innovative Tankless Design

Unlike conventional reverse osmosis water filters, the PD400 system features an impact design without a bulky tank. This allows for up to 70% space savings and fits most standard US cabinets perfectly, eliminating the risk of secondary pollution due to unventilated tanks. Built-in water cycle boards ensure that the entire system is safe from water leakage.

Low Drain Ratio & Ultra Long Service Life

The PD400 system boasts a remarkable low drain ratio of 1.5:1 (pure: drain), saving approximately 450% more water compared to standard systems. With a daily filtration capacity of 400 gallons, the tankless water filter produces instant pure water to lead-free faucets, filling a cup in just 12 seconds. The system includes two large filter cartridges, extending its service life to an impressive level, at only $0.2 per day.

DIY Installation & Replacement

Easy installation and replacement highlight this system. Compatible with most standard US kitchens (1/2” and 3/8”), the PD400 comes with a comprehensive manual, a quick guide, and an instructional video. Everything needed for installation is included, and no plumber is required. The replacement process is quick and straightforward, taking only 2 seconds with a twisting cartridge design. A smart filter life indicator chirps to remind you when it’s time to change.

Multi-Usage

The PD400 can serve both your sink and refrigerator simultaneously. By using the Frizzlife IMC-1 Ice Maker Kit, the system can provide pure water for both purposes. To address the common issue of unstable water pressure when connected to refrigerators, the system will launch a mini tank specifically tailored for tankless RO systems. This resolves the initial lag in water outflow, ensuring continuous, crisp, and tasty pure water at home, eliminating the need for bottled water.
