Complete with dual sediment and carbon pre-filtration, two unique reverse osmosis membranes and a final carbon post-filter that ensures excellent-tasting drinking water. The tankless design means no water-storage tank or pump is required to operate, providing a versatile solution to many alternative applications (such as car cleaning, window cleaning and aquatics).

Product Features

  • Produces high quality contaminant-free drinking water
  • Tankless design with no storage tank or pump
  • Versatile and portable RO solution
What Is Included

The Pentair PRF RO system comes with everything you need to get started, including all membranes, pre-filters and post-filters. You also get several additional accessories including a drinking water faucet, fitting kit, flexible tubing, drain kit and feed pressure gauge. A full instruction manual is also included within the box.

Installation Info

Before installing the system, ensure you have sufficient water pressure to operate. A minimum of 2.8 bar feed pressure is required to operate effectively, with a max pressure of 5.5 bar. For private water supplies or applications with high levels of sediment or contaminants, additional pre-filtration is recommended to increase the lifespan of the membrane. The system utilises push fit connections for an easy installation, with flexible tubing included. Relevant resources for installation can be found linked below.

PENTAIR PRF RO SYSTEM

High Flow Rate Tankless Design

The Pentair PRF RO system offers high production rates of up to 2,600 litres per day, with a tankless design that provides crystal-clear purified water on demand. Featuring two membranes and an intelligent water-recovery system, it achieves an average rejection rate of 93% making it up to 75% more efficient than most other domestic RO systems on the market. This means less waste, lower operating costs and better performance. The lightweight and portable construction of this system makes it a versatile option not only for drinking water but for a whole host of light commercial applications with a requirement for purified water.

Why Use A Reverse Osmosis System?
Reverse osmosis removes up to 99% of dissolved contaminants including PFAS, nitrates, fluoride, lead, bacteria and much more – giving you great-tasting purified drinking water without health concerns. It’s perfect for homes with hard water, eliminating excess sodium when used alongside a water softener. Plus, it protects kettles, coffee machines and boiler taps from limescale buildup, extending their lifespan.

How Long Do The Filters Last?
On average the carbon pre and post-filters should be changed every six months. The membranes should be replaced when you notice a slower flow rate or a change in water quality. With soft water you can expect the RO membranes to last 2-3 years, or with hard water around 1-2 years.

Why Choose The Pentair PRF RO System?

  • NSF/ANSI 58 certified for contaminant removal
  • Effective removal of fluoride, bacteria, lead and PFAS
  • High production rate of up to 2,600 litres per day
  • Lightweight and portable with no storage tank
  • Efficient with a 93% rejection rate

Very pleased with the service. There was an issue with the water softener I ordered initially, but then following communications made the replacement process quite pleasant. Happily recommend this company. Thanks to Becky for working with me. Great follow up support 😊😊😊

First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

Excellent service. Product proved my softener was not working as it should. I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed. Very pleased.

If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd. Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly. All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now. HIGHLY recommend them!

Easy to order, quick delivery, good communication. Resclean worked a treat; one treatment cycle and soft water is back again from our 12 yr old softener!
