Brio SIMPL Key Specs Explained

Capacity (GPD): 800

This rating indicates the system can produce up to 800 gallons of purified water daily. You benefit from a steady supply for cooking, drinking, and ice making without waiting for a tank to refill. This capacity suits larger families or small offices. When shopping, compare this number to smaller 50 or 75 GPD models to understand the volume difference in daily use.

Filtration Stages: 4

The system uses four distinct steps to clean your water. This includes a PAC composite filter to capture dirt, rust, chlorine, VOCs, and fine silts before the water reaches the main membrane. More stages generally mean broader contaminant removal. You should compare this against 3-stage units to see if the extra filtration step meets your specific water quality needs.

Pure to Drain Ratio: 2:1

For every two cups of clean water you get, one cup is sent to the drain. This ratio measures efficiency. A lower waste ratio means less water usage per gallon produced. You save on water bills compared to older systems with higher waste rates. Check this spec against competitors to find the most water-efficient model for your home.

Design: Under sink

This unit is built to install beneath your kitchen sink. It connects to your existing water line and faucet. You save counter space by keeping the hardware out of sight. Compare this installation type with countertop models to decide if you prefer a hidden setup or a portable unit that does not require permanent plumbing connections.

Design and build specs

The Brio SIMPL is an under-sink system with a tankless layout. According to the listing, its integrated waterway system uses minimal connections to reduce leak risk. This sealed design conforms to NSF 372 standards. The unit measures 14 inches in length, 5.2 inches in width, and 13.8 inches in height. It weighs 17.2 pounds. The compact footprint saves up to 70% of undersink space compared to traditional tank systems. This small size makes it suitable for smaller cabinets where storage is limited. You do not need extra room for a pressure tank.

The system features a brushed nickel faucet included in the package. Operation relies on just three buttons for simple control. You avoid complex digital interfaces or app connectivity. The 4-stage filtration process protects the RO membrane while capturing dirt, rust, chlorine, VOCs, and fine silts. The PAC composite filter handles initial contaminants before the water reaches the membrane. This structure supports maximum efficiency. The tankless design ensures you get fast 2 LPM dispense flow. You benefit from immediate purified water without waiting for a tank to refill. The straightforward mechanical controls and compact dimensions prioritize practical installation and easy maintenance in tight spaces.

Setup And Everyday Use Guide

Installation relies on the included under-sink components. You receive three color-coded tubes, a feedwater adapter, a drain saddle, lock clips, and a flow restrictor. These parts connect the system to your plumbing without complex tools. The unit itself is compact, measuring 14 inches long, 5.2 inches wide, and 13.8 inches high. It weighs 17.2 pounds. This small footprint saves space compared to traditional tank-based models. You mount the brushed nickel faucet on your sink or countertop for direct access to filtered water.

Daily operation is streamlined. The system features just three buttons for control. This simple interface lets you manage the filtration process without navigating a digital display or app. You do not need to wait for a storage tank to fill. The tankless design delivers water on demand. You get a fast dispense flow of 2 liters per minute. This speed supports quick filling of pots or pitchers.

Efficiency is built into the design. The system maintains a 2:1 pure-to-waste ratio. For every two cups of clean water you dispense, only one cup goes to waste. This ratio helps conserve water during routine use. The four-stage filtration protects the membrane. The PAC composite filter captures dirt, rust, chlorine, VOCs, and fine silts. This pre-filtration step ensures the main RO filter lasts longer. You replace the PAC filter every 12 months and the RO filter every 24 months. Search for the specific Brio replacement cartridges to maintain performance.

Before You Buy This RO System

You need to check your under-sink space before buying. This unit measures 14 inches long, 5.2 inches wide, and 13.8 inches high. It saves space compared to tank models, but you must verify clearance for the brushed nickel faucet and drain saddle. The 2:1 pure-to-waste ratio means you use one cup of wastewater for every two cups of clean water. Ensure your drain line can handle this flow. Upkeep involves replacing the PAC filter annually and the RO membrane every two years. Search for specific Brio replacement cartridges to maintain performance. If you have a large family or office, the 800 GPD capacity fits well. Smaller households might prefer the 400 or 600 GPD versions to reduce water waste. This system suits those who want fast flow without the bulk of a storage tank. It is a practical choice for modern kitchens where space and speed matter most.

Check before you buy

• Measure under-sink clearance for the 14-inch length and 5.2-inch width.
• Confirm drain line capacity for the 2:1 pure-to-waste ratio.
• Verify faucet hole size for the included brushed nickel fixture.
• Check annual PAC and biennial RO filter replacement costs.
