Filtration Performance
Filtration is where this system shines. The multi-stage purification process removes a wide range of contaminants, including:
- Heavy metals (lead, arsenic, mercury)
- Chlorine and volatile organic compounds (VOCs)
- Microorganisms and bacteria
- Sediments, rust, and other particulates
The NSF 58 & 42 certification ensures that the water is both safe and tastes fresh. Unlike standard RO systems, this one minimizes water waste with a 2.5:1 pure-to-drain ratio, making it eco-friendly and cost-effective.

Water Flow & Pressure
One of the most frustrating aspects of traditional RO systems is slow water flow. The CRS-RO800 eliminates that issue with an 800 GPD capacity, meaning you’ll get purified water on demand, without waiting. Whether you’re filling a pot for cooking or just grabbing a glass to drink, the high flow rate is a major plus.
Smart Features & User Experience
The built-in LED display provides real-time updates on water quality, filter life, and system status. This is a great feature for first-time RO users, as it eliminates the guesswork of when to replace filters.
