A quick look at the benefits IONEX brings into your home.











IONEX d.o.o., founded by inventor Lorena Leonardos, develops top-tier products powered by a unique patented carbon-brush technology. Our devices reach the strongest emission of negative ions, capable of destroying viruses, as demonstrated by Prof. Dr. Oxford of London.
»I develop the product we sell, personally. Every batch of ionizers passes through our hands and our responsibility.«
“Years ago, smoking was allowed in all indoor spaces, which denied us non-smokers the right to clean air. While researching, I discovered the remarkable properties of negative ions, which effectively remove smoke and other impurities from the air while also benefiting the body. That is when my life's vision was born – to let people breathe clean air indoors. Using a patented and unique carbon brush, I achieved the emission of negative ions without harmful ozone. Today, the widespread use of our ionizers in homes, offices, schools, healthcare facilities and cars ensures quality living practically everywhere, because we know that clean air is the foundation of a healthy life.”
Lorena Leonardos founds her first company and starts researching negative-ion technology.
IONEX is founded; the patented carbon brush is developed to emit negative ions without ozone.
Lorena Leonardos becomes the first solo woman nominated for Slovenian Entrepreneur of the Year.
Slovenian Chamber of Commerce awards the silver innovation prize for IONEX Car: built-in negative-ion emitter for vehicles.
Lorena Leonardos publishes Slovenia's first book on ionization. IONEX expands into HVAC and automotive industries.
European Union backs the IONEXAir project under Horizon 2020 (grant 809132). IONEX wins first place among 2,589 entries.
IONEX carries certificates from recognised institutions plus independent ion- and ozone-emission measurements. The only ionizer rated for extreme sauna conditions (up to 100 °C and 100% humidity).

The values below are natural concentrations of negative ions (ions / cm³). Indoor air carries the least. IONEX produces 199 million negative ions every second, enriching the room toward natural levels. The actual indoor concentration depends on room size and ventilation.
Output the device releases into the room; the resulting ion field depends on room size.
Metal needles, plasma emitters and membranes produce oxides and ozone, both harmful to the lungs. A carbon brush emits negative ions directly into the room with no by-product.
People spend most of their lives indoors. The air they breathe there is typically depleted of negative ions and loaded with positively charged pollutants.
IONEX emits negative ions from a carbon brush without ozone. They pull carcinogenic soot, exhaust, dust, cigarette smoke, viruses, bacteria, mite waste, odours and other particles out of the air — particles that no filter can hold.
The effect is continuous. Around the clock you breathe air carrying 199 million negative ions per cubic centimetre.
»Negative ions are the only thing capable of destroying even viruses.«
Prof. Oxford backed his findings with a public video, available on YouTube.
Ion emission measurements were performed by the Jožef Stefan Institute. The device holds SIQ, CE, IEC, CB, EMC, LVD, RoHS, GS and TÜV certificates. Randomised studies in ionised workplaces recorded 30 percent fewer sick days.
»Prof. Krueger of Philadelphia proved that mice die when negative ions are stripped from the oxygen they breathe, and concluded that without negative ions there is no life.«
»After ionizers were installed in astronaut quarters, chronic muscle cramping stopped.«
»BBC London: air conditioning that stripped negative ions became a Legionella hotspot.«
Ozone emissions were measured by the Institute of Occupational Safety (ZVD) using SIST EN methods. The result is below the detection limit.
The only unpleasant side effect is a fine layer of dust that settles around the device. Don't worry: those are carcinogenic exhaust particles that would otherwise end up in your lungs. Now you simply wipe them off the surfaces.
No filter in the world can hold particles that small. Negative ions are the only real defense. You deserve clean air at home and at work.
Synthetic fibres, neon lighting, air conditioners, consumer electronics and metal frames fill the air with positive ions. The result is fatigue, headaches, asthma, allergies and poor sleep.
Split AC units create friction inside ducts and destroy negative ions.
A car body physically acts as a Faraday cage with no ions inside, so they must be added by an automotive ionizer. At the same time the ions remove carcinogenic exhaust fumes from the cabin air.
HEPA filters trap particles down to 0.3 μm, missing the most dangerous 0.01 μm ones.
Opening a window only helps briefly. IONEX works 24 hours straight.

What our owners say about IONEX.
»There is a restaurant beneath my apartment, so every day I was exposed to food smells and cigarette smoke. Since I installed two ionizers in the bedroom, I no longer smell anything unpleasant, and I no longer need to open the windows for fresh air. Negative ions accompany me in the kitchen and living room too. I am genuinely grateful to IONEX for clean air rich in negative ions.«
»We have used the ionizer at home for years — in the living room, the bedroom and the car. They have become indispensable in our family. I recommend the car ionizer to anyone who drives long distances. The same goes for the living-room and bedroom models.«
»My life is spent travelling and staying in hotels for work. I always returned exhausted and short on sleep. Now I take the IONEX ionizer with me and plug it in as soon as I reach the hotel room. Sometimes I even inhale the negative ions directly — it makes me feel as if I were outside in nature, even in a closed room.«
»Our family has near-nomadic habits — we travel a lot, in our motorhome. We installed two ionizers, one in the cabin, the other in the rear sleeping quarters. Even on long trips I am never tired thanks to the negative ions from IONEX. I have introduced many friends to it.«
»I took my IONEX with me abroad to a new job. Colleagues looked oddly at the small black device on my desk and kept stopping by, saying they felt good around me. When I explained it was the negative ions, they all wanted one — and the boss was happy to oblige. They bought ionizers for home as well as for the office.«
»I am allergic to dust and dust mites, so I often couldn't fall asleep because of a tormenting cough. After using the IONEX ionizer the cough no longer appears, because the air is clean. The most important thing is that my blood pressure dropped from the usual 160/90–170/95 to 135/85, on the same dose of the same medication. As I didn't trust my own monitor, I had my doctor check too — and he confirmed the same result.«
»I am a retired physician and oncological surgeon. Since childhood I have suffered from very frequent infections, both bacterial and viral. The cause was a disorder of the white blood cells (T and B lymphocytes), which left my immune response very weak. With age these problems only grew worse, and after retirement they were compounded by the after-effects of major surgeries. I also struggled with allergies to various medications and environmental allergens. I decided to try the IONEX ionizer to see if it might help reduce my problems. After regular use I have fewer infections, fewer allergic episodes, and I noticed that this ionizer also very quickly removes unpleasant smells from the room. My observations so far support a reduction in both infections and allergies.«
»A symphony of well-being and pleasure takes hold of our bodies whenever the little friend IONEX creates a microclimate charged with negative ions. We feel as if after a thunderstorm — many of the discomforts that wear us down fade, and above all we become more relaxed, calmer and full of energy. Confirmation of these beneficial effects on the body rests on countless positive experiences over decades. We don't only reach for the ionizer when conventional medicine has reached its limits — it helps just as much in full health, as we doctors constantly advise that many health complaints can be eased or vanish if we manage to avoid stress. That the research on the effect of beneficial negative ions on the body is positive is best seen for yourself. What matters is achieving good results without side effects, and ionization makes that possible. Sustained exposure to ionized air produces lasting improvement. Negative ions are a natural antidepressant and they help with insomnia. Reading the book on ionization, one cannot omit praise for the remarkable effort the author has put into presenting therapy, prevention and environmental hygiene with the highly beneficial negative ions. Perhaps the proven benefits of ionization will encourage many to take a similar step and live in friendship and symbiosis with the kindly companion that is the IONEX ionizer. My own experience confirms the facts stated above.«
»We bought the ionizer because dust was bothering us, especially in the children's room. After a few days of use we noticed that the dust no longer rose into the air but settled on surfaces, which made it much easier to remove. We particularly recommend it to families with small children, and to anyone who wants to do a little more to protect their health.«
»IONEX ionizers have served us at home and at work for more than ten years. I am very satisfied — we feel better and our health is better. In 2018 I added the car ionizer when three of us travelled across Spain and Portugal one summer. We covered almost 11,000 km with the ionizer running constantly, with outside temperatures above 30 °C and no air conditioning. The results were remarkable: we needed at least 2 to 3 hours less sleep; we were never tired — not even after 6 to 16 hours of driving; we were always ready for activity — full of spontaneous new ideas; we co-operated creatively the whole time — not a single conflict; we were always in good spirits — every day we laughed at our own expense. The team was unanimous: the ionizer made a huge difference on the trip.«
»I received an IONEX ionizer as a gift and I use it 24 hours a day. Since I began using it I have noticed that my day-to-day well-being has improved, I'm more focused, I get through daily tasks more easily and with more energy. I also sleep better at night. I sometimes used the ionizer for my sick, now late, father, since he was bedridden. I noticed that he slept better and breathed more easily and cleanly. During that time he did not get infected and caught no bacteria or virus — which sadly happened to him later in hospital. That is why I would warmly recommend the use of ionizers in hospitals, care homes and other facilities and institutions where larger numbers of sick and healthy people gather.«
»My sleep was always a mystery — I never knew how long I would lie awake before drifting off. Since I started keeping the IONEX ionizer by the bed, my sleep has become genuinely good.«
»Two months ago I bought an ionizer from you, and I can already say with certainty that my decision was the right one. The air throughout my home is wonderful, and the problems caused by my chronically dry nasal mucosa are noticeably improving.«
»I work as a nurse in a well-known Slovenian hospital, caring for very seriously ill patients who are confined to bed. A few years ago a patient's daughter asked if she could bring an ionizer and hang it above her mother's bed, where the lifting handle was. She explained that the device emits negative ions, makes the air cleaner and also destroys viruses. I didn't believe the story, but I let her hang the thing above the bed anyway. She assured me it would use barely a euro's worth of electricity in a whole year. Over time I noticed that the air in that room was always clean and we didn't need to open the windows to ventilate. The patient also slept peacefully through the night, which was not common among the other patients. I got the impression that this IONEX device really does remove smells from the air. Today I have one at home and I'm grateful to the patient's daughter for introducing me to the ionizer.«
