Recognized for decades as the best choice for families. 7 electrodes, 5 water types, proven technology — an ionizer that has stood the test of time.
SD501 is not a "new hit" — it is the model that has been Enagic's number one seller worldwide for years. Not without reason.
SD501 has been sold by Enagic since the 1990s. Enagic still services units manufactured 25 years ago — that is not a coincidence. The design has not changed because it works perfectly.
25+ year lifespan7 massive platinum-coated titanium plates generate ORP up to -600 mV. For a family of 3–5, this is the perfect value — clearly above any bottled or filtered water.
ORP up to −600 mVSD501 holds a Class II medical device certificate from Japan's Ministry of Health, Labour and Welfare (MHLW) — certified by the Japanese government, not by the manufacturer. View certificates →
Medical Class IIpH 9.5 for drinking, pH 8.5 for cooking rice and tea, pH 7 for babies and medication, pH 6 for skincare, pH 2.5 as a natural disinfectant. One device for everything.
5 water typesSD501 DX delivers 95% of the K8's capabilities at a slightly lower price. For most families, this is the ideal balance — outstanding quality without overpaying for performance you won't notice.
Best value for moneySD501 DX announces the selected water type, filter status, and cleaning reminders by voice. A clear voice confirms every change — no mistakes, no guesswork. Intuitive from day one.

Enagic has been manufacturing the SD501 for over 25 years — and in that time has never needed to fundamentally redesign it. Why? Because the design was right from the beginning. The massive platinum-coated titanium electrodes do not degrade like those in budget ionizers. Automatic electrolysis cleaning after every use keeps the machine in optimal condition for years.
In Poland and around the world, thousands of SD501 units are still running perfectly after 15–20 years. This is not marketing — these are facts you can verify by talking to actual users.

"I was sceptical as a pharmacist. I tested it with my own ORP meter — results exactly as in the specifications. I noticed a difference in hydration and wellbeing within the first week. SD501DX for two years now."
"I hesitated for a year. Now, after 3 years, I am certain — it was the best health decision our family ever made. We save over €300 a year on bottled water. The children refuse to drink anything else."
