Ecoviva 1000GPD UnderSink Reverse Osmosis (RO1000G, 8-Stage Filtration)

What contaminants does this reverse osmosis system remove?

The 8-stage filtration system removes 99.99% of contaminants including lead, chlorine, PFAS (forever chemicals), bacteria, viruses, heavy metals, pesticides, pharmaceuticals and over 1,000 other harmful substances. The 0.0001μm RO membrane is fine enough to block virtually all dissolved solids whilst the carbon filters handle chlorine and organic compounds. The system meets NSF/ANSI 58 standards for contaminant reduction.

How much space does this system require under the sink?

The tankless design measures 16.5cm wide x 47.6cm long x 43.4cm high and weighs 10.6kg. It saves 70% more space than traditional tank-based RO systems. You'll need approximately 20 inches (51cm) of height clearance for installation and filter changes. The system can be wall-mounted to the cabinet wall, leaving floor space free for other storage. An electrical outlet under the sink is required.

What is the water efficiency and how much does it cost to operate?

This system achieves an industry-leading 3:1 pure-to-waste ratio, meaning it produces 3 gallons of clean water for every 1 gallon of wastewater. This is 300% more efficient than traditional RO systems. Operating costs are approximately £0.08 per day (converted from $0.10), making it 90% cheaper than buying bottled water. The wastewater can be collected and reused for plants or cleaning.

How often do the filters need replacing and what do they cost?

The RO membrane lasts 2 years (6,000 litres) thanks to the auto-flush feature that extends its life. Pre-filters typically need replacing every 6-12 months depending on water quality and usage. The smart faucet displays filter life alerts so you know exactly when to change them. Replacement filter costs range from £70-£110 for a complete set, making annual maintenance very affordable.

Does this system require professional installation?

The system is designed for DIY installation and takes approximately 30 minutes to complete. It includes universal adapters for both 3/8" and 1/4" pipes, detailed instructions and all necessary components. You'll need basic tools and must drill a hole in your countertop for the dedicated RO faucet. An electrical outlet under the sink is required. Some customers prefer professional installation for peace of mind.

What type of water does this system produce?

The system produces alkaline water with a pH between 7-8 and stable TDS levels of 7-9. This is ideal drinking water that's neither too acidic nor too alkaline. The mineralisation stage adds back beneficial minerals after the RO process, creating balanced, healthy drinking water. The smart faucet displays real-time TDS readings so you can monitor water quality.

Can this system be used in apartments, RVs or rental properties?

Yes, the compact design and universal adapters make it suitable for apartments, RVs, offices and rental properties. The system connects to standard water lines and requires only a small hole for the faucet. It's easily removable if you move house. However, you'll need permission to drill the countertop hole and access to an electrical outlet under the sink.

How fast does this system produce water compared to other RO systems?

With 1000 gallons per day capacity, this system fills an 8oz cup in just 4 seconds. The maximum flow rate is 2.6 litres per minute, significantly faster than traditional RO systems that often take 30-60 seconds to fill a glass. The high flow rate means no waiting for water, making it practical for large families or high-usage situations like offices.
