What stands out
- 800 GPD membrane capacity for fast filling
- 3:1 pure-to-drain water efficiency ratio
- NSF/ANSI 58, 61, and 372 certifications
- Tankless design with continuous fresh filtration
- Fully sealed structure for noise reduction
Who it fits
Good fit for
You should choose this system if you need high daily water output without storing water in a tank. The 3:1 efficiency ratio suits households wanting to reduce wastewater. The NSF certifications provide verified safety for drinking water. If you value a quiet operation under the sink, the sealed design helps. The alkaline filter adds minerals back into the water. This setup works well for families who drink large volumes of water daily.
Who should skip it
You should skip this model if your under-sink cabinet is smaller than 18.8 by 17.1 by 6.5 inches. The system requires drilling two holes for the faucet and drain. You also need a nearby electrical outlet, as this is not a gravity-fed unit. If you prefer a system with a storage tank for backup during power outages, the tankless design will not meet that need. Check your space and power availability before proceeding.
Verdict: This tankless RO system offers high flow and certified safety for efficient daily use. It fits well in spacious cabinets where power and drainage are accessible.
Key specs for Ecoviva 800GPD
Capacity: 800 GPD
This rating indicates the membrane produces up to 800 gallons per day under standard test conditions. In practice, you get fast flow from the faucet, filling a glass in seconds. This high output suits households with heavy water use or large families. It reduces wait times for drinking water compared to slower 50 GPD systems. Note that actual daily output depends on water pressure and temperature.
Pure to Drain Ratio: 3:1
For every three gallons of clean water produced, only one gallon goes to drain. This 3:1 ratio is significantly more efficient than traditional RO systems that often waste two or three gallons of water per gallon of product. Lower waste means less strain on your water supply and fewer trips to the drain line. This efficiency is a key benefit for eco-conscious buyers.
Certification: NSF/ANSI 58, 61, 372
These certifications verify specific safety and performance standards. NSF/ANSI 58 confirms the system effectively reduces contaminants listed on its label. NSF/ANSI 61 ensures materials contacting water do not leach harmful chemicals into your drinking supply. NSF/ANSI 372 guarantees the system contains no lead above 0.25%. These third-party tests provide objective proof of material safety and filtration performance.
Filtration Stages: 9
The system uses a nine-stage process to filter water before it reaches your faucet. This multi-stage approach typically includes sediment pre-filters, carbon blocks, the RO membrane, and post-filters. Each stage targets different impurities, such as chlorine, sediment, or taste issues. More stages generally mean more thorough filtration and better taste compared to simpler three or five-stage units.
Micron Rating: 0.0001 μm
This number describes the pore size of the reverse osmosis membrane. A rating of 0.0001 micrometers is extremely small, allowing only water molecules to pass through. This tight filter blocks dissolved solids, heavy metals, microplastics, and other microscopic contaminants. It is the core mechanism that delivers purified water. Compare this to standard carbon filters, which have much larger pores and do not remove dissolved salts.
Design and Build Quality
The Ecoviva unit follows a tankless under-sink design. According to the listing, it uses a fully sealed structure to reduce vibration and operational noise. This construction aims to enhance durability for long-term use. The system is white and weighs 20.7 pounds. Its dimensions are 18.8 inches in length, 17.1 inches in width, and 6.5 inches in height. You must verify that your cabinet space exceeds these measurements before installation.
The layout requires drilling two holes: one for the faucet on the countertop and another for the drain connection under the sink. A nearby electrical outlet is also necessary for operation. The tankless design supports continuous fresh filtration without stored water. This approach ensures you always get recently filtered water. The premium coconut-shell carbon filter improves taste, while the alkaline filter adds minerals.
This compact form factor fits standard under-sink cabinets. The noise reduction features make it suitable for quiet kitchens. The German engineering principles suggest a focus on structural integrity. You benefit from a system that does not take up extra space with a storage tank. The straightforward installation needs power and plumbing access. Ensure your space meets the size requirements for a proper fit.
Setup And Everyday Use
Installation requires specific cabinet space and utility connections. The unit measures 18.8 inches in length, 17.1 inches in width, and 6.5 inches in height. You must verify that your under-sink cabinet dimensions exceed these measurements. The setup involves drilling two holes: one on the countertop for the faucet and another for the drain connection. A nearby electrical outlet is also necessary for operation.
The tankless design means you do not need to manage a storage tank. This configuration supports continuous fresh filtration, ensuring water is processed on demand. The system utilizes a 9-stage filtration process, including an alkaline filter and a premium coconut-shell carbon filter. These components work to improve taste and reduce TDS, microplastics, and heavy metals.
Daily use centers on the 800 GPD membrane performance. The 0.0001 μm rating allows for rapid filtration, filling a glass in seconds. The 3:1 pure-to-drain ratio indicates higher water efficiency compared to traditional systems. This ratio means for every three parts of purified water produced, one part is drained. The fully sealed structure aims to reduce operational noise and vibration during this process. You benefit from consistent flow without waiting for a tank to refill. The white finish integrates into standard kitchen cabinetry. Always confirm your plumbing setup matches these requirements before beginning installation.
Check Space And Power Needs
Before you buy this Ecoviva 800GPD system, check your under-sink space carefully. The unit measures 18.8 inches long, 17.1 inches wide, and 6.5 inches high. Your cabinet must be larger than these dimensions to fit the tankless design. You will need a nearby electrical outlet, as this is not a gravity-fed system. Two holes require drilling: one for the faucet and another for the drain line. The 3:1 pure-to-drain ratio means you use three gallons of water to produce one gallon of filtered water. This affects your water bill and drain frequency. The alkaline filter adds minerals, which may change the taste profile compared to standard RO units. Verify your water pressure supports the high flow rate. If your home has low pressure, the output may drop significantly. This model suits large households needing fast flow. Smaller kitchens might find the footprint too large for other storage needs.
Check before you buy
- Measure cabinet interior against 18.8 by 17.1 by 6.5 inches
- Confirm nearby electrical outlet exists under the sink
- Check water pressure supports 800 GPD membrane flow
- Ensure drain line connection is accessible for installation
- Verify faucet hole drilling is permitted in your countertop
