Pure Water Straight from the Tap

With a filtration accuracy of 0.0001um, this system efficiently removes contaminants like fluoride, limescale and heavy metals.

No More Waiting for Water

The Finerfilters tankless RO systems are "direct flow" which means that they use a booster pump and fast-filtering technology to ensure pure drinking water is readily available from the moment you turn the tap, unlike a traditional RO system which can take several hours to produce and store enough pure water to be dispensed.

Cleaner & More Compact

The innovative tankless RO system eliminates the risk of secondary pollution from traditional storage tanks where bacteria eventually starts to build up and takes up to 70% less storage space under your sink.

Eco-Friendly & Economical

With a 1.5:1 low drain rate and a high-water flow rate of 600 GPD, our fast-filtering RO system wastes 34% less water than the traditional ones and is much more efficient with a flow rate of 2.1 litres per minute!

The Best Multi-Layer Composite Filtration

The 5 in 2 filters offer a smart filtration system for better, purer water at a lower overall cost. The integrated filter design ensures high purity, softened, perfect to drink water.

Finerfilters 5 Stage Reverse Osmosis System - Direct Flow, Tankless, Compact!

The Finerfilters DFT9 Direct Flow, Tankless, and Compact Reverse Osmosis system is the latest addition to our catalogue of RO units.

These brand new systems offer all the features and benefits of a traditional reverse osmosis system, without the negatives such as lengthy installation and setup processes, awkward or messy filter changes, and long , wasteful production of pure drinking water.

Fast Filtration and High-Water Flow.

Unlike slow, traditional RO systems, our tankless RO system uses a booster pump and fast-filtering technology to ensure a continuous water supply and a high water flow rate, while reducing water waste by 34%.

With our 600GPD (gallons per day) system you can enjoy flow rates of up to 1.6L per minute.
With our 800 GPD (gallons per day) system you can enjoy flow rates of up to 2.1L per minute.

Meaning you can fill a glass of water with pure RO water in just a few seconds!

Cost & Time Effective Filtration.

We’ve combined 5 filters into 2 - meaning you save 30% on filter replacement costs when compared to other systems all while achieving a higher level of filtration.

The filter composition technology has an ultimate filtration accuracy of 0.0001µm.

Much Greater Production Rates.

Traditional RO systems usually work on a 3:1 ratio which means you lose 3 litres of waste water for every 1L of pure water.

Our tankless, direct flow systems are capable of achieveing pure water production rates of only 1.5:1 which is a significant reduction in water waste that in turn saves you money (especially if on a water meter) and is kinder to the environment.

No More Harmful Contaminants.

The innovative filtration system eliminates more than 1000 contaminants keeping your water safe from chlorine, heavy metals, turbidity, scale, bad taste and odour.

As well as some more toxic inorganic and organic contaminants like arsenic, fluoride, asbestos, benzene, formaldehyde, lindane, phenytoin, nitrate/nitrite, bisphenol A, trichloromethane, chlordane, etc.

Easy Installation and Filter Replacement.

No need for professional installation - Anyone can install the RO system in only 30 minutes. The filters are also easily changed out within seconds - making replacement simple.

The 30 mins installation & 3 seconds filter change can be seen in the how-to video in the 'Product Videos' tab and in the downloadable instruction manual in the 'Attachments' Tab

Intelligent Touch Screen Display.

The Finerfilters Direct Flow, Tankless RO System looks and feels great to use. With it's highly sensitive and responsive touch control screen you are able to easily cycle through options and operate your RO system.

The on-screen display shows vital information such as the TDS of your water and filter life, so you know exactly when they need to be replaced.

Better than Traditional RO Systems.

Our direct flow RO systems are simply levels above a traditional Reverse Osmosis system.
