Years of research by our engineers on negative ion generation has resulted in an air ionizer capable of emitting up to 20 million beneficial negative ions per second, making it the best negative ion generator on the market.

The ionMi eclipses other ionic generators by a factor of 10 or even 20 times. This breakthrough and patented negative ion technology, proven in scientific studies, provides you and your family with cleaner, safer and healthier indoor air quality.


Plugging into any USB outlet, the ionMi makes the ideal air purifier for your home, workplace, vacations and international travel.

Filter-less and maintenance free for life, you don’t have to worry about replacing expensive air filters, like with other air purifiers. Lightweight, compact and portable, with an elegant and modern style, it makes a great desktop air cleaner you can take anywhere.


Built in dual voltage power supply removes the hassle of finding the right electrical converter when you are travelling internationally. No outlet in sight? Connect with ease to your laptop or any USB outlet (Phone Charger, Computer, Car, RV).

Running at an ultra-low 1.5 watts, the ionMi’s multi-power supply technology brings you clean air in any environment, worry free and extremely energy efficient, costing just pennies to run.


Don’t let its tiny size fool you — this negative ion generator is small but mighty. The ionMi can deliver up to 20 times as many negative ions as ionizers of a similar size. It even produces significantly more ions than most far larger and more expensive ionic air purifiers.

It’s what’s inside that counts. Take advantage of our state-of-the-art ionic technology and breathe a sigh of relief.


Each ionMi is individually tested and measured in our facilities by a negative ion counter to ensure that every one emits up to 20 million negative ions per second.

This quality control and assurance guarantees that your ionMi can remove Airborne Bacteria and Viruses, Tobacco Smoke & Pet Odors, Mold Spores and Other Allergens, Harmful Dust, and Allergy Causing Pet Dander and Pollen from the air you breathe.

    This unit is the best ionic air purifier at a price you cannot complain about. It is very compact and portable. I am thrilled I found this unit online and I use it daily and will take it with me as I travel.

    I’ve been a ionbox 20m user for a few years now and when I saw that this new portable unit came out I had to give it a try. So far, I am loving it! I have been using the ionMi on my commutes to work. Because of the ionMi, my car is fresher and I feel better. I discovered about negative ions a few years ago and have been an advocate for their benefits… been telling all my friends and family about them ever since!

    I like the ionMi because of its small size. I can wear it around my neck and feel the negative ions near my face. When I don’t want to wear it on my neck I simply just place it in my pocket. The battery life of the unit can last up to 14 days depending on what power setting you use. It only takes a couple hours to power to full, so I really don’t need to worry about it running out of power.

    In conclusion, if you are a fan of the ionbox 20m, definitely check out the ionMi! You will not be dissapointed.

    I ordered two items of this.

    It is actually a plasma ion generator and not just negative ion. Which made me love the product even more! I tested using my ion counter. Plasma ion inactivates viruses.

    It has four modes (as written in their manual)
    Strong – Lasts for 14 hours. For indoor & outdoor, especially for those areas with high sanitary standards, such as clinic, hospital, smoking area, inside car, office, etc.
    Power saving – Lasts for 3 days. Suitable for closet and shoes cabinet, handbags, etc. for odor & bacteria removal
    Extreme power saving – Lasts 7 days. Suitable for refrigerator for odor & bacteria removal.
    Off –

    Charging is 4 to 5 hours.

    Thank you.

    I used it on the ship in my cabin. It smells a little like clorox when it’s working but i believe it helped protect me from respiratory illnesses.

This must be dropping particles out of the air because my allergies have improved remarkably! I keep it in the living room where I spend much of my time. It's quiet so you only know it's on if there's complete silence in the room, sound…...Read more

"All modern homes should have an ion generator. We are bombarded with positive ions continually from our electronics and the grid. Balancing that out takes effort. So glad to find one that's affordable. I do think I need to get a couple more to achieve…...Read more

"This little thing is great, I’m not sure why the reviews aren’t better! It was the best quality ionizer I could find for the price. It is low ozone producing and doesn’t have a UV-C filter, which were both important to me. I’ve been using…...Read more
