This brio aquus troe800col reverse osmosis review focuses on a tankless under-sink system designed for high-volume purification. The unit measures roughly 5.2 by 16.6 inches, allowing it to occupy only about 30% of typical cabinet space. Two specs define its performance: an 800 GPD capacity and a 2:1 pure-to-drain ratio. These figures suggest it delivers water quickly while minimizing waste compared to traditional systems. The four-stage filtration process includes NSF-certified components to reduce contaminants like TDS and sediment. You get a compact design that prioritizes flow rate and efficiency without the bulk of a storage tank.
What stands out
- 800 GPD capacity dispenses one cup in under eight seconds
- 2:1 pure-to-drain ratio reduces wastewater significantly
- NSF/ANSI 42 and 58 certifications for contaminant reduction
- Smart faucet with TDS meter and filter life indicators
- Front-access filter replacement with no tools required
Who it fits
Good fit for
This system suits households with high water usage needs, such as large families or those who cook frequently. The 800 GPD output ensures you have purified water on demand without waiting for a tank to refill. The 2:1 ratio is ideal for users concerned about water waste. The tankless design fits well in smaller under-sink cabinets where space is at a premium. If you want a modern faucet with real-time TDS monitoring and easy filter changes, this unit meets those requirements.
Who should skip it
You should look elsewhere if you prefer a system with a separate storage tank for backup water during outages. This model relies entirely on immediate flow, so you cannot access purified water if the supply is cut. If you need a faucet with more than two lever options or digital temperature controls, this unit does not offer them. Additionally, if your primary concern is only basic sediment filtration without TDS reduction, the complex four-stage RO process may be unnecessary for your needs.
Verdict: The Brio AQUUS TROE800COL offers high-capacity, space-saving purification with efficient water usage. It is a strong choice for users prioritizing flow rate and modern smart features.
Key specs explained for this RO unit
Capacity (GPD): 800
This rating indicates the system produces up to 800 gallons of purified water daily. You will receive a cup of water in under eight seconds. This flow rate suits households with high daily drinking and cooking needs. It ensures you never wait long for fresh water during busy times like meal preparation or when making baby formula.
Pure to Drain Ratio: 2:1
For every two cups of clean water, this system wastes only one cup. Traditional systems often waste four cups for every one cup of pure water. This lower ratio saves water and reduces your utility bills. It is a significant efficiency improvement over older tank-based models that struggle with higher waste ratios during operation.
Certification: NSF/ANSI 42, 58
These standards verify the system reduces sediment, chlorine, and total dissolved solids. NSF 42 covers aesthetic improvements like taste and smell. NSF 58 confirms the removal of harmful contaminants like lead and arsenic. These certifications provide independent proof that the filters work as advertised, giving you confidence in the water quality.
Micron Rating: 0.0001 microns
This pore size defines the tightness of the reverse osmosis membrane. Smaller pores block more microscopic particles. This rating ensures the removal of dissolved solids and heavy metals that standard filters miss. It is the core mechanism that turns tap water into purified drinking water by physically blocking contaminants.
Filtration Stages: 4
The system uses four distinct steps to clean the water. The PCB filter handles sediment, chlorine, and iron before the water reaches the main membrane. This pre-filtration protects the expensive RO membrane from clogging. It extends the lifespan of the membrane and ensures consistent performance over time by removing larger particles first.
Design and build details
The Brio AQUUS TROE800COL features a tankless, under-sink design finished in black. According to the listing, the unit measures approximately 5.2 inches wide, 16.6 inches high, and 18.2 inches deep. This compact footprint occupies roughly 30% of standard cabinet space, leaving 70% available for storage. The system weighs 32 pounds, which provides stability during operation without requiring excessive mounting hardware.
The layout centers on a space-saving, integrated housing that eliminates the need for a separate storage tank. This design choice reduces the risk of recontamination and prevents leaks associated with traditional bladder tanks. You install the unit under your sink, where it connects directly to your plumbing. The tankless configuration means you do not need to manage water pressure fluctuations from a pressurized container.
Controls are located on the smart faucet, which includes two levers. One handle dispenses PCB-filtered water for tasks like washing produce, while the other provides RO-purified water for drinking. The faucet also displays TDS levels and filter life percentages via LED indicators. This dual-lever setup allows you to separate pre-filtration from final purification at the point of use. The filters are accessed from the front with a quarter-turn motion, simplifying maintenance without moving the entire system.
Setup and everyday use
Installation requires the included kit and manual. You connect the system under your sink. The design allows for tool-free filter changes. You remove and install filters from the front with a quick quarter turn. No need to move the unit or store parts. This simplifies maintenance for the PCB and RO filters. The PCB filter needs replacement every six to twelve months. The RO filter lasts twelve to twenty-four months. You can find the correct replacement parts by searching specific model numbers. Daily use centers on the dual-lever smart faucet. One lever dispenses water filtered by the PCB stage. This water has no wastewater and suits washing produce or watering plants. The other lever provides RO-purified water. This water is ideal for drinking and making baby formula. The faucet includes an LED display showing TDS levels. It also displays the remaining filter life as a percentage. This helps you track when service is needed. The system produces up to 800 gallons per day. You can get a cup of water in under eight seconds. The pure-to-drain ratio is 2:1. This means for every two cups of clean water, one cup goes to drain. This ratio saves water compared to older systems with a 1:4 ratio. The tankless design prevents recontamination. You do not need a storage tank. This keeps water fresh and saves cabinet space.
Before you buy this RO system
You should verify your sink cabinet has enough depth for the 18.2-inch unit. The tankless design saves space, but you still need room for the filter cartridges. Check your water pressure. This 800 GPD system works best with adequate pressure to maintain flow. You will need to budget for replacement filters. The PCB filter lasts six to twelve months, while the RO membrane lasts twelve to twenty-four months. Keep the part numbers handy for easy ordering. Consider your faucet holes. This unit includes a smart faucet with two levers. Your sink must have two holes or you may need an adapter. This system suits large families needing high volume. It fits well alongside smaller tank models if you prioritize speed and space. Just ensure your plumbing connections match the included kit. Regular maintenance keeps the TDS meter accurate and the water pure.
Check before you buy
- Confirm sink cabinet depth exceeds 18 inches.
- Check for two faucet holes or adapters.
- Verify water pressure meets system requirements.
- Plan for PCB filter replacements every 6-12 months.
