This ecoviva e8 800 gpd reverse review focuses on a tankless under-sink RO system that prioritizes flow rate and compact installation. The unit delivers 800 gallons of purified water per day without a storage tank, making it suitable for high-demand households. It features a nine-stage filtration process with a 0.0001 μm membrane to remove contaminants like lead and arsenic. The system is certified by SGS to meet NSF/ANSI 42 and 58 standards. Its slim profile measures just 5 inches wide, allowing it to fit into tight under-sink spaces while providing real-time water quality data via a smart faucet display.
What stands out
- 800 GPD tankless flow rate for instant water access
- 9-stage filtration with 0.0001 μm RO membrane
- SGS certified to NSF/ANSI 42 and 58 standards
- Smart faucet with real-time TDS and filter status display
- Compact dimensions of 16.5 x 5 x 12.2 inches
Who it fits
Good fit for
This system suits busy families who need high-volume water without waiting for a tank to refill. The tankless design ensures you always have fresh, purified water on demand. It is ideal for kitchens with limited under-sink space due to its narrow 5-inch width. The real-time TDS display helps users monitor water purity and filter health easily. If you want certified contaminant reduction for lead and fluoride, this unit meets those needs.
Who should skip it
You should look elsewhere if you prefer a traditional system with a storage tank, as this model is tankless. The 2.5:1 pure-to-drain ratio means it uses more water during filtration than some high-efficiency models. If you need a faucet without a digital display, the smart faucet here might be unnecessary complexity. Also, consider that the 5-year warranty excludes filters and mineralization media, so you will need to replace those components regularly.
Verdict: The Ecoviva E8 offers high flow and certified purity in a compact, tankless design. It is a strong choice for space-constrained kitchens needing rapid water access.
Key specs explained
Capacity (GPD): 800
This rating indicates the system produces 800 gallons of purified water daily. As a tankless unit, it delivers water on demand rather than storing it in a pressurized container. This high flow rate suits busy households with multiple taps or large families. You get immediate access to clean water without waiting for a tank to refill. Compare this capacity to standard 50-gallon units to see the difference in convenience for daily cooking and drinking needs.
Certification: NSF/ANSI 42, 58
These certifications mean the system has been independently tested by SGS to reduce specific contaminants. NSF/ANSI 42 covers aesthetic effects like taste and odor, while NSF/ANSI 58 ensures the removal of contaminants such as lead, fluoride, and arsenic. You can trust the filtration claims because they meet established safety standards. When shopping, look for these marks to verify that the manufacturer has validated their purity claims through rigorous third-party testing.
Micron Rating: 0.0001 μm
This number refers to the pore size of the reverse osmosis membrane. A rating of 0.0001 microns is extremely small, allowing only water molecules to pass through while blocking larger impurities. This precision helps reduce over 99% of total dissolved solids. You benefit from water that is free from heavy metals and chemicals. This spec is a key indicator of filtration quality, so compare it with other systems to ensure you are getting a high-grade membrane.
Pure to Drain Ratio: 2.5:1
This ratio shows that for every 2.5 gallons of clean water produced, the system wastes one gallon as drain water. A lower ratio is more water-efficient, so 2.5:1 is a moderate performance level. You will use less water compared to older, less efficient models, but it is not the most eco-friendly option available. Consider this when calculating your long-term water usage costs. Compare this figure with other tankless RO systems to find a balance between flow speed and conservation.
Compact Black Design Specs
According to the listing, the Ecoviva E8 measures 16.5 inches long, 5 inches wide, and 12.2 inches high. It weighs 18.3 pounds. The unit is finished in black. This slim profile is engineered to fit into cramped under-sink spaces. You do not need a large cabinet to house it. The tankless design removes the bulky storage pressure vessel found in traditional systems. This saves significant vertical and horizontal room. The compact footprint ensures it clears most standard kitchen plumbing configurations without major modifications.
The system uses a nine-stage filtration process. The core membrane has a micron rating of 0.0001 micrometers. This precision allows it to reduce over 99% of total dissolved solids. It targets contaminants like lead, fluoride, and arsenic. The unit holds NSF/ANSI 42 and 58 certifications for impurity reduction. These standards verify the materials contact water safely and effectively remove specified pollutants. The certification provides a baseline for purity claims.
Control and monitoring come through a smart faucet. This fixture displays real-time TDS readings. It also shows filter status. You can see water purity levels directly at the tap. This feature removes guesswork from maintenance schedules. The faucet acts as your primary interface for system health. It complements the internal filtration stages by providing immediate feedback. The design prioritizes space efficiency and visible water quality data for daily use.
Setup And Everyday Use
Setup begins with placing the compact unit under your sink. The listing specifies dimensions of 16.5 inches long, 5 inches wide, and 12.2 inches high. This slim profile is designed to fit into cramped spaces without consuming excessive cabinet volume. You will connect the system to your cold water line and install the dedicated faucet on your countertop or sink deck. Because this is an under-sink installation, you need adequate space behind the faucet for the filter housing.
Daily use relies on the tankless design. The system produces 800 gallons of purified water per day. You get instant, on-demand clean water straight from the tap. There is no waiting for a tank to refill. This high flow rate suits busy households with multiple taps.
The smart faucet provides real-time TDS readings and filter status. You can see your water’s purity at a glance. This display takes the guesswork out of maintenance. You know when to replace filters without testing the water yourself.
The unit features a 2.5:1 pure-to-drain ratio. This significantly reduces water waste compared to older systems. The RO filter lasts up to 24 months. This cuts down replacement frequency. The system is certified by SGS to meet NSF/ANSI 42 and 58 standards. It reduces impurities including lead, fluoride, and arsenic. You enjoy peace of mind with every glass. The black finish blends into most kitchen cabinets. Maintenance is straightforward thanks to the real-time display.
Before You Buy This RO System
Before you commit to the Ecoviva E8, verify your sink cabinet dimensions carefully. The unit measures 16.5 by 5 by 12.2 inches. While slim, it requires specific clearance. You must also confirm your water pressure supports a tankless system. Low pressure can significantly reduce the 800 GPD flow rate. Check that your plumbing connections match the included fittings. The smart faucet requires a separate hole in your sink or countertop. Ensure you have space for this installation. Upkeep involves monitoring the real-time TDS display to track filter health. The listing notes a 24-month filter lifespan. Plan for these replacements to maintain the 2.5:1 pure-to-drain ratio. This system suits high-demand users who prioritize speed over storage. It fits well among tankless options if you need instant water. However, if you have limited counter space for the faucet, consider models with integrated displays. Always cross-check your household’s daily water usage against the 800 GPD capacity.
Check before you buy
- Measure your under-sink cabinet for 16.5 by 5 by 12.2 inches.
- Confirm water pressure supports tankless 800 GPD flow rates.
- Ensure sink has a hole for the smart faucet.
- Check plumbing compatibility with included fittings.
- Plan for 24-month filter replacement schedule.
