Customers Reviews

“My hay fever was so bad that I was considering surgery, but I started using the IONION and now I don’t even take medicine.” (Man in his 60s)
My pollen allergies were so bad that I constantly had a runny nose and couldn’t stop sneezing. I was even thinking about getting sinus surgery. A friend told me about the IONION and since I started wearing it around my neck, those symptoms lightened up and now I don’t even take any medicine. My son was also having problems with pollen allergies, and his symptoms went away thanks to the IONION.
“I don’t get colds anymore.” (Woman in her 40s)
My company handed them out, so I’ve been using the IONION for about three years. I used to catch colds two or three times a year, but I stopped getting colds since starting to use the IONION. Wearing it gives me peace of mind. Especially in these circumstances nowadays.
“I have asthma, and it became easier to breathe from the moment I put it on.”(Woman in her 40s)
I have terrible asthma and even before COVID-19, I would always have to wear a mask when I went out. I found the IONION when I was looking for an air purifier I could carry, as I wanted to clean the air around me. I thought this was exactly what I wanted and bought it right away. It became easier to breathe from the moment I put it on. These days I wear a mask because of COVID-19, but I’m fine now even without a mask.
“My dog allergies got better.”(Man in his 50s)
Both my wife and I have severe dog allergies and we always needed to have medicine handy, but soon we realized that we had gotten better without ever taking medicine. I thought we could never have our dog sleep on the bed with us, but now we do, which really surprised me.

4Key Features about the Latest IONION PREMIUM

It is so light that you’ll forget you’re wearing it around your neck. It is small enough also to wear underneath your clothing.

Note: Can also be kept in a breast pocket.

Features 2
ion barrier
protects your body
When you wear the IONION NEO, it charges your body with negative ions, creating an ion barrier with patented technology. The effect is stronger when the IONION is worn on the body.
It also elevates the metabolism of serotonin, which allows the body to relax and calms agitation in the autonomic nervous system.

Other brands are not the same!

Features 3
Eliminates 99.9% of PM2.5
Verification tests on concentration reduction were conducted on a PM2.5 density of approximately 52,400 particulates/cc in a 60-liter box. When the IONION NEO was activated in this sealed space, the tests showed a 99.9% decomposition and adsorption of PM2.5.

Note: Product testing was performed under controlled conditions. We cannot guarantee identical results under real-world conditions.

With the IONION in the box, when smoke was blown in, the smoke was eliminated over time.

The results indicate that pollen and dust will have difficulty entering the body.

Features 4
Negative ion output of
Verified by the Japan Association of Ion Research and Application
(measured by JIS standards)
Negligible* ozone generated
Some types of negative ion generators produce ozone, but the IONION NEO generates no detectable ozone, so it can be used safely by everyone, including children and seniors.

* Measurements resulted in negligible output, less than 1/100th (0.001 ppm) the safe level stipulated by Japan’s Ministry of Health, Labour and Welfare.

Company measurements found a negative ion output of over 20 million ions. Please watch the video below to see for yourself.
