5 Stage Tankless RO System


Our 5 Stage Tankless RO System is a pumped, direct flow reverse osmosis system which removes dissolved contaminants to deliver top quality, purified drinking water straight from the tap. Featuring 5 stages of filtration including sediment control, dual carbon pre-filtration, reverse osmosis stage and carbon post-filter to remove an extensive list of contaminants including chlorine, heavy metals, fluoride, sodium, nitrates, hormones, asbestos, lead, PFOS, arsenic and more. These RO systems are particularly popular as they have a small footprint, supplied pre-assembled on a frame and without a storage tank, making them suitable for even the tightest of under-sink installations.

Why Choose Our 5 Stage Tankless RO System?

  • Up to 300 gallons per day of purified drinking water
  • Direct flow with no tank for reduced footprint
  • 5 Stage pumped reverse osmosis system
  • Easy to install and low maintenance

Reverse osmosis is commonly used to produce purified drinking water from either a mains or private water supply. By forcing water at pressure through a semi-permeable membrane, dissolved contaminants are removed and sent down the drain whilst the purified water flows straight to the tap. The space saving design and ease of installation make our 5 Stage Tankless RO System a favourite for customers who are conscious about what is in their drinking water, as well as for those looking to remove excess sodium from softened water.

The quality of water produced by this system is excellent, meaning its uses extend far beyond drinking water… it can also be used for ironing, ice making, spot-free rinsing of glassware and even for watering sensitive plants like orchids! Using reverse osmosis water in your kettle or coffee machine is also a great idea, not only because your drinks will taste amazing but you’ll also be waving goodbye to limescale and protecting your much-loved appliances.

How Often Do I Need To Replace The Filters In The 5 Stage Tankless RO System?
The sediment filter, granular carbon pre-filter, carbon block pre-filter and carbon post-filter should be changed every six months. The RO membrane should be replaced every 2-3 years if you have soft water, or every 1-2 years if you have hard water.

Key Product Information:

  • Multi-stage filtration to improve the taste, odour and appearance of drinking water
  • Integrated booster pump to increase membrane efficiency and flow rate
  • Popular for removing excess sodium from softened water
  • Suitable for customers with low incoming water pressure
  • Supplied as a complete kit ready to be installed

Lovely company to deal with and prompt delivery. I'm in the scottish highlands and they recognised that post is better than courier for rural deliveries.
A wide range of filters ( and UV bulbs) available. Extremely prompt delivery at a very competitive price. Great follow up customer care too.

I bought the wound sediment filters. I found the filters arrived very quickly. It was later followed by a courtesy call to make sure the product was received and correct. Just fitted the filter and it is working very well. Very friendly customer service, would not hesitate to reorder from them in the future.
