Performance Benefits

Top Tier Filtration Performance

The PD400 under sink reverse osmosis water filtration system offers top-tier pre-filter and RO membrane technology, achieving a filtration precision of 0.0001 micron. This deep 5-stage filtration process eliminates over 1000 harmful contaminants, including Lead, Chlorine, Fluoride, Heavy metals, Chloramine, VOCs, TDS, Limescale, Arsenic, and Asbestos. The system also includes a TDS meter, allowing you to monitor your water quality precisely.

Innovative Tankless Design

Unlike traditional RO systems, the PD400 reverse osmosis system features an impact design without a bulky tank. This innovative setup saves up to 70% of space and fits seamlessly into most standard US cabinets. The integrated water cycle board prevents any secondary contamination, ensuring that only pure, clean water reaches your faucet. No need to worry about unventilated tanks or potential water leakage.

Low Drain Ratio & Ultra Long Service Life

With a remarkable low drain ratio of 1.5:1 (pure water to drain water), the PD400 system significantly reduces water waste, saving up to 450% compared to conventional RO systems with a 1:3 ratio. The high daily capacity of 400 gallons ensures a constant supply of fresh, pure water. The tankless design fills a cup within just 12 seconds. Thanks to its two large filter cartridges, this system boasts an ultra-long service life, costing only $0.2 per day.

DIY Installation & Replacement

The PD400 system is compatible with most standard US kitchen faucets (1/2” & 3/8”). It comes with a comprehensive manual, a quick guide, and a step-by-step instructional video, making installation straightforward. Everything needed for installation is included, and the process does not require a plumber. The replacement is quick and easy with a TWIST-IN cartridge design. A smart filter life indicator beeps to notify you when it’s time to change. Search ASR211 & ASR212-400 for replacement filters.

Multi-Usage

The PD400 RO filter system can serve both your sink and refrigerator simultaneously with the Frizzlife IMC-1 Ice Maker Kit. To overcome the common issue of low water pressure when connected to refrigerators, the system will soon feature a mini tank designed for tankless RO systems, eliminating initial water flow lag. Enjoy instant, crispy, and tasty pure water from your home, eliminating the need for bottled water.
