Is this the right RO system for me?
Reverse osmosis provides the most thorough water filtration available. If you have standard under-sink space, the 5-Stage Ultra High Purity is exactly what you need for ultimate peace of mind. It tackles harsh water and older plumbing with a dedicated sediment pre-filter, then adds essential minerals back in for perfectly balanced, healthy hydration.
Tight on space? If you have a smaller kitchen, or limited under-sink room, check out our Compact 4-Stage Reverse Osmosis Filter with Alkaliser. It offers the same premium purification in a streamlined design—perfect for tight spaces.
What’s the difference between the Alkahydrate and the Omnipure remineraliser?
Choose Omnipure for a 100% USA-made internal filter path, or Alkahydrate for our most popular, cost-effective alkalising option.
Can I use this RO system for tank and bore water?
This system is best suited for town (mains) water. Tank water sources often lack the required water pressure required for RO systems. For tank or bore water, please explore our Rain Water Tank Filter options.

I couldn’t be happier with my 7 stage RO system.
The water it produces is fantastic to drink and has improved my hydration vastly!
I did allot of homework on which system was the best quality and most affordable. I’m very happy I went with living whole.
The team were extremely helpful to trouble shoot the installation, and Janka is the absolute best to deal with, she’s so helpful and knowledgeable.
Very happy cutomer.

I knew our water had fluoride and other contaminants, but I wasn’t sure what system to choose. After doing some research, I decided on the 5-stage reverse osmosis system and I’m so glad I did. It was easy to install, the water tastes amazing, and I finally feel at ease knowing my family is drinking clean, filtered water every day.

Living Whole –
Hi Andre, thanks for your review!
Jim Fox –
Brett was very helpful on the phone. Got a plumber to install system and thus far all is good. The initial aeration in the water has gone and taste improves the more the system is used. Now taste is quite good.
