Do you need the pumped version?
Standard RO systems need at least 3 bar of water pressure to work properly. Most UK homes have this — but a minority don't. Here's a quick way to check without measuring anything.
Turn your kitchen cold tap on full. If the flow is vigorous and you get small splashes standing near the sink, your pressure is likely fine. If the stream is thin or weak even at full flow, you probably need this pumped version.
You likely need the pumped version if...
→Your kitchen cold tap feels weak — low flow or thin stream even when fully open
→You're on the top floor of a flat or a high-floor property
→Your water supplier has told you your pressure is below 3 bar
→You have a gravity-fed system — common in older UK properties with a tank in the loft
Not sure? Call us on 020 8761 6611 — we'll help you choose the right version in two minutes, free of charge.

Why does this cost less than comparable systems?
The honest answer has two parts.
First: we don't add filter stages you don't need.
Some suppliers market their RO systems by the number of "stages" — five-stage, seven-stage, even nine-stage.
More stages sounds more impressive.
But the filtration science doesn't support it.
A well-engineered RO system needs
a good pre-filter (we give you two),
the membrane
a remineraliser/ realkaliser filter
a post-filter (to polish the water before it reaches your tap.)
That's five stages.
Everything beyond that is either redundant, marginal in benefit, or added specifically to justify a higher price.
We know this because we've been in water filtration for over 25 years. We understand what each stage actually does — and doesn't do. So we build the system around the science, not around the price tag. (More info here on unnecessary RO "stages")
Second: we sell direct, online only.
No showrooms, no sales reps visiting your home, no retail margins. Those costs don't make the water any cleaner, but they do make the unit considerably more expensive when other suppliers pass them on to you. We don't.
The result is a system that is, in our assessment, technically superior to many units sold at £400–£500 — at around half the price.
The 3-year warranty and 90-day money-back guarantee are there precisely because we're confident in that claim.
Installation — straightforward, no specialist needed
The pump comes fully pre-fitted and pre-wired inside the unit. This matters: retro-fitting a pump to an existing non-pumped RO system is genuinely complex and best avoided. This system arrives ready to connect — no electrical work required from you beyond plugging into a standard socket.
1
Mount under sink
Fits inside a standard kitchen base unit. Tank can sit nearby or a few feet away with extra tubing
2
Connect the water
Saddle valve taps your existing cold pipe. Works on 12mm and 15mm pipes — covers 99% of UK homes
3
Plug in & run
Plug into any standard 3-pin socket. Fill and discard the first two tanks — then your water is ready
Replacing the filters — simple, and we remind you when it's time
Like all RO systems, the filters need periodic replacement to maintain performance. We send you a free reminder when each change is due — you replace the cartridges only, not the housings.
A few minutes — cartridges drop in, no tools needed
First set included
Yes — all filters supplied with the system
Pre-filter cartridges and membrane drop into their housings. Post-filter tubing push-fits into place. You replace the cartridges, not the housings. We send a reminder when it's time.

Why we include a re-mineraliser — and why most UK suppliers don't
RO filtration removes dissolved minerals including calcium and magnesium, which act as a natural pH buffer in tap water. Without them, filtered water becomes mildly acidic — typically pH 5.5–6.5 — and can taste flat.
Our system passes purified water through a mineral restoration cartridge before it reaches your tap, raising pH back to a neutral 7–8 and restoring the taste profile of good natural spring water. This is standard practice in the Far East where RO is widespread. Most UK suppliers skip it. We include it as standard, at no extra cost.
A note on waste water
RO filtration rejects approximately 70% of incoming water as part of the purification process — this is a characteristic of the technology, not a flaw in this unit. The rejected water goes down the drain automatically. To put it in perspective: this only affects the small volume of water used for drinking and cooking, not your shower, washing machine or garden. The rejected water is clean enough to reuse for garden watering if you'd like to reduce waste.

Capacity / Production Rate - Gallons Per Day (GPD) 75 Gals
Feed temp (Degrees C) 4 to 29
Weight 19kg
Dimensions
RO unit: 49.5cm High x 37.2cm wide x 19.5cm deep
Storage vessel is 40cm High x 27cm wide
The 12 Litre Tank / Storage Vessel (Freestanding, connected to RO unit by tube, can be placed several yards away - simply ask us for some extra tubing).
The unit should be fed by a water supply that is potable i.e. drinkable.
Please note that Reverse Osmosis is a complex process requiring reliable equipment performing under high pressure. Always know where your water main stopcock is located in the unlikely event of leaks.
The filter system doesn't have to be at a level below the tap and neither does the tank as long as it's not a gravity fed system.
This model will produce 50 GPD ie its "production rate" is 75 gallons per day.
(This assumes perfect conditions ie clean water at the right temperature and that incoming pressure is good).
But when considering how much water is produced by any Reverse Osmosis filter, the most important factor is the size of your RO tank.
This is because your system feeds the tank then stops when it's full.
Here's how it works: When you draw water from your RO you are taking water from the tank. As the tank empties the system refills it at the "production rate" (ie 50 GPD) up to the tank's capacity.
Now, in addition to this, you have to consider that the tank's size is based on the actual physical dimension and not the amount of water it contains.
You have to also take into account the internal bladder that holds the water inside of the tank.
For example, the bladder inside this unit's nominal 12 litre tank will actually hold between 5 to 9 litres of water. If you draw all the water out of the tank it will take anywhere from half an hour to 4 hours to fill up again - depending on incoming water pressure.
Therefore the amount of water this size produces is 5 to 9 litres per average of 2 hours - on a stop/start basis. (Note that you only have to wait for more water if you fully drain the tank in one go. In our experience this happens very rarely with normal domestic usage).
Other typical tank sizes and the actual water they hold are:
18L nominal tank size: Holds 12 to 15 Litres
40L nominal tank size: Holds 23 to 28 Litres
For High Flow / High Capacity Reverse Osmosis systems click here
The simplest way to check your water pressure is to turn your cold water tap in the kitchen on full. Stand a few feet away. If you are being splashed with at least a few droplets then your pressure should be high enough.
If this is not happening, your local water supplier should be able to tell you what your water pressure is and whether it is likely to drop below 40 psi at any time.
The Unit is NOT designed to filter HOT water. It should only filter water at ambient temperature. (Feed temp = 4 to 29 degrees C).
However please note that our Reverse Osmosis units are often used to supply filtered water to hot/boiling water taps and other systems where the temperature is changed. That is fine. But the system itself should not filter hot water.
What are the Materials Inside the Reverse Osmosis Tanks?
Some people are concerned about the materials the RO tanks are made from and how it might impact their purified water.
This is understandable:
Who wants to filter their water carefully only for it to be somehow polluted in the storage vessel while waiting to be used!
(Just to be clear: RO filtration is a highly effective but slow process. Rather than you waiting for the filter to produce enough water for you, the system purifies the water slowly and fills up the storage vessel / tank. When you turn on the RO drinking tap there's several litres of filtered water waiting for you. The system then refills the tank with whatever you took out).
Our RO tanks / storage vessels are made from highly durable steel. The water doesn't touch this - which is a good thing or the highly purified water could cause the metal to release chromium oxide into the water!
Instead, the water is stored inside an airtight rubber bladder / diaphragm.
This is made from "butyl rubber" which is lined with polypropylene - a commonly used food grade plastic (see "Hazard data" below).
All these materials are industry standard. We have never come across and other type of materials for Reverse Osmosis storage tanks - and, collectively, we've been in water filtration for over 50 years.
(Bear in mind that after leaving the tank the water is purified even further by the post filters).
Polypropylene Hazard Data:
No negative health effects and symptoms.
No negative physical and chemical effects.
No hazard for environment.

Such an improvement over unfiltered water. Losing microplastics, scale, chlorine and all the other nasties that can work their way in is just a bit of piece of mind for me in relation to my kids.
– Nick Love
I've had the filter installed for 1 month now and the water tastes loads better and no more smell of chemicals, just clean fresh filtered water I'd say it's the best water I've ever had.

“My filter fits easy and I am happy. We weigh the old filter when it is removed, filled with gunge which never got into our bodies with this filter. It’s quite frightening. My filter is worth every penny!
