How We Got Here And Why It Matters
When we first looked into water filters, we felt overwhelmed too. So many options and so much jargon. That’s why we started Living Whole – one filter at a time. From our first distiller over to benchtop water filter and now reverse osmosis. Every filter has been carefully researched. Now, nearly 10 years on and with 40+ years of combined team experience, we’ve helped thousands of families find the right filter for their home.
Clean Water Shouldn’t Be Complicated — Just Clear, Safe, and Ready
At Living Whole, we understand that you simply want to feel at ease about the water your family drinks every day.
To feel that way, you need a water filter that doesn’t just remove the usual suspects — like chlorine, chloramine, heavy metals, and PFAS — but also targets fluoride and balances your water with natural alkalinity.
The problem is, tap water often contains a long list of unwanted contaminants. And even when you’re trying to make the best choices, that uncertainty can leave you feeling unsure and frustrated.
We believe no one should have to second-guess something as essential as the water they drink.
Here’s how it works:
- Choose the CTO Max Undersink Filter with Fluoride Removal and Alkaliser
- We prepare and assemble it for you, with all the parts included
- Install it once — and enjoy clean, alkaline water every day with zero fuss
Order your under sink filter today, so you can stop worrying about hidden contaminants and start drinking with calm, confidence, and clarity.
