Recognised for decades as the best choice for families. 7 electrodes, 5 water types, proven technology — an ionizer that has stood the test of time.
The SD501DX is not a "new sensation" — it's the model that has been Enagic's number one in global sales for years. Not without reason.
The SD501DX has been sold by Enagic since the 1990s. Enagic services devices manufactured 25 years ago — that is no accident. The design hasn't 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 an excellent value — clearly above any bottled or filtered water.
ORP up to −600 mVThe SD501DX holds a Class II medical device certificate from Japan's Ministry of Health, Labour and Welfare (MHLW) — confirmed 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 infants and medication, pH 6 for skincare, pH 2.5 as a natural disinfectant. One device for everything.
5 water typesThe SD501DX offers 95% of the K8's capabilities at a somewhat lower price. For most families this is the ideal balance — exceptional quality without overpaying for parameters you won't feel the difference of.
Best price-to-quality ratioThe SD501DX announces the selected water type, filter status and cleaning by voice. A clear voice confirms every change — no mistakes, no guessing. Intuitive operation from day one.
Voice announcements"When you buy an SD501DX, you are buying not a product — you are buying decades of Japanese engineering precision."
Enagic has been manufacturing the SD501DX for over 25 years — and throughout that time has not needed to fundamentally change it. Why? Because the design has been correct from the start. Massive platinum-coated titanium electrodes don't wear out like those in budget ionizers. Automatic electrolysis cleaning after every use keeps the device in optimal condition for years.
In Poland and around the world there are thousands of SD501DX units that have been working perfectly for 15–20 years. That is not marketing — it's a fact you can verify by speaking with users.

Output and quality perfectly matched to the daily needs of a typical family. Everyone gets their water — from infants to grandparents.
Entering the world of alkaline water? The SD501DX is the ideal starting point — complete, proven, without quality compromise.
Care about natural antioxidants, hydration and reducing chemicals in your diet? SD501DX gives you −600 mV ORP every day, without supplements.
pH 9.5 water draws more flavour from tea and rice. pH 11.5 removes pesticides from fruit without chemicals. Cooking on a new level.
"I was sceptical as a pharmacist. I tested with my own ORP meter — results exactly as in the specification. I noticed the difference in hydration and wellbeing within the first week. SD501DX for two years."
"I hesitated for a year. Now after 3 years I'm certain — it was the best health decision in our family's history. We save €330/year on bottled water. The children won't drink anything else."
"Mum after chemotherapy needs the best hydration. Her doctor had no objections — the water is neutral or alkaline, natural. After 6 months mum drinks 2.5 litres a day. She couldn't manage even 1 litre before."
"I ride 200+ km per week. I was looking for water that absorbs faster and better supports recovery after long rides. Had SD501DX for a year — subjectively: fewer cramps, recover form faster after effort."
"Remote work, stress, too little exercise — permanent fatigue was my daily reality. A dermatologist suggested improving hydration. I bought SD501DX and didn't expect that simply drinking better water would change so much."
"Parents in their seventies. Dad with kidney issues — doctor recommended drinking plenty, but dad didn't like tap water taste. SD501DX bought for them. Now he drinks two litres without prompting. Kangen water really does taste different."
"We tried to get the kids to drink more water instead of juices and soft drinks. SD501DX turned out to be a breakthrough — the kids pour it themselves and ask for more. Unexpected side effect: they reach for sweets less because they're better hydrated."
"For years my priority has been clean, good quality water. I researched RO filters, carbon filters, ceramic filters. SD501DX gives something more than filtration — a change in water properties. I recommend it to clients who take hydration seriously."
"I followed molecular hydrogen research for two years. I tried H2 tablets — the effect was short-lived. SD501DX is the complete solution: water with H2 every day, different pH types, solid Japanese construction. The obvious choice."
"At work I measure ORP of various water samples. I measured SD501DX with my own laboratory equipment — results match the specification. As a technician I approach this rationally: water with low ORP is a measurable fact, not marketing."
"Mum lives alone, after hip surgery, needs good hydration for recovery. I installed SD501DX for her — simple to use, one button. Mum drinks regularly and says she feels better than after months of rehabilitation."
"I've recommended alkaline water to clients for years — but I was still drinking from bottles myself. SD501DX bought once I calculated the annual cost of premium bottled alkaline water. The financial difference is huge — and home water is always fresh, not sitting in plastic for weeks."
"12-hour ward shifts, constant movement. Hydration is a professional and health matter for me. SD501DX at home — I come back after a night shift and drink. My legs ache less in the evening. Simple hydration, clear difference."
"Daughter has allergies — we were looking for clean water without chlorine and heavy metals. SD501DX filters and ionizes. After a year of use daughter is drinking much more, seasonal allergies are milder. We don't attribute everything to water, but we continue."
"Parents' GP encouraged better hydration. I bought them SD501DX. Both drink regularly and both feel their joints work better. They didn't expect a miracle — they are enjoying the improved quality of daily life."
"I researched hydrogen-rich water for a year. I chose SD501DX because Enagic is a brand with history and certifications. I don't buy a pig in a poke — I checked the technical documentation before making a decision. Purchase without regret."
"We both work intellectually for 10 hours a day. Mental exhaustion was our daily reality. After a month with SD501DX we both notice we are less distracted in the afternoon. Hydration makes a difference."
"Four children, sporty husband, me with Hashimoto's. Each of us needed something different. SD501DX gives different water types — alkaline for drinking, acidic for skincare, neutral for taking medication. One device for the whole family."
