The Best Negative Ion Generators | Home Air Ionizer Reviews 2017
If you’re looking for the best negative ion generator without ozone, this page has a detailed review of high-density negative ionizers for sale and why they are recommended.
Negative Ions versus Ozone
Keep in mind, this is a review for true high-density corona discharge air ionizers. Most ionizer reviews covers ‘ionic air purifiers’ or ‘anion ionizers’, which tend to be catchall terms for devices that use primarily ozone, rather than negative ions, to clean the air.
While ozone emitting ionizers are good for eliminating odors and airborne toxins, and may incorporate ion generation, like this popular one, they generally aren’t recommended for extended periods of use near where you work or sleep.
Ozone is reactive and unstable and if you can smell it – that faint bleach/office printer smell – then you probably shouldn’t be breathing it in for long periods.
Negative ions, on the other hand, are exceptionally healthy to breathe in when generated properly, and will also clear the air without the smell of ozone.
In fact, many people say the air in their home has never smelt so fresh and clean once they start using a high-quality negative ion generator, like the ones recommended ahead.
What to Look for in a Good Air Ionizer
First of all, if you’re looking for a true high-density negative ion generator, rather than an ozone generating ionic air purifier, look for the manufacturer to specifically state the negative ion output per second (the higher the better).
If the product doesn’t list the amount of negative ions produced, and especially if it is labeled ‘ionic purifier’ or ‘anion air ionizer’, it’s likely that ozone generation, rather than negative ion production, is the primary air cleaning method.
The best negative ion generators will list their ion output in the millions per second and specifically state that they don’t produce ozone (or under the safe 0.05 ppm CDC limit). If they don’t, then consider them suspect.
Good air ionizes should also be very cheap to run, with low voltage and requiring little energy, even when left on all day, as many users like myself do.
Now that you know what to look for in a good negative ionizer, let’s review the best ones I’ve found on Amazon for a reliable place to buy them from.
Best Portable Ionizer with USB — IonBox Review
To be honest, the small and portable ionizer market has been crying out for a product like the recently released IonBox.
It’s small enough to fit in the palm of your hand, yet generates an impressive 20 million negative ions per second, far more than any similarly sized ionizer I could find (most of which are primarily ozone generators).
IonPacific, the manufacturers of IonBox, claim it is capable of quickly removing cigarette smoke, airborne bacteria, pet dander, pollen and other allergens from the air you breathe.
They also say it delivers its air cleaning ions in an area up to 500 sq feet, without producing detectable ozone and has a one year warranty.
Two other things I particularly like about the IonBox home ionizer are that there are no replacement parts ever needed and the fact that it can connect not only to a regular power socket but also to a USB port on your laptop, computer or even in modern cars.
It’s also very energy efficient, using a minimal 1.5 watts of electricity. You could easily keep this on your work desk all day to counteract positive ions from electrical equipment with hardly any power consumption.
Other good positions for it would be in the bedroom, kitchen to eliminate smoke and cooking smells, and in the lounge room, near where you watch TV.
The IonBox is also great as a travel air ionizer due to its lightweight and small portable design. Some reviewers recommend getting a few of these little air purifiers as they are so useful in different environments.
If you’re looking for the best portable ionizer in a small size, yet with a high negative ion output, it’s hard to go past the IonBox by IonPacific.

Best High-Density Negative Ionizer — Wein Vi-2500 Review
While not as pretty as the previous ionizer, the Wein Vi-2500 is extremely powerful, generating an incredible 450 trillion negative ions/sec cm2 according to the manufacturer, with a coverage of 800 sq feet (a 40′ x 20′ room). All without detectable levels of ozone.
Power usage is less than 6 watts and they say, even with continuous usage, it should cost just pennies a month to run.
The manufacturer also says that testing shows the Wein air ionizer will remove more than 98% of respirable particles, like germs, dust, pollen and pollution, from a very large room in just one hour.
The Wein high-density negative ionizer is made by a private company and one of the owners hold several patents, which may help to explain why the Wein Vi-2500 is such a powerful negative ionizer at such a low price.
A one-year manufacturer’s warranty is also included with the Wein Vi-2500 ionizer, my pick for the best high-density negative ion generator on the market.
Best Negative Ionizer with HEPA Filter and Germicidal UV Lamp — Surround Air MT-8500 Review
The Surround Air Multi-Tech 8500, on the other hand, bills itself as six proven air cleaning technologies in one unit to deal with virtually every kind of airborne allergen and pollution.
The 6 technologies used in this advanced ionizing air purifier are:
- A true HEPA filter, as recommended by the US Center for Disease Control, to provide effective filtering for allergens like mold toxins, dust mites, pollen, pet dander and many other airborne particles.
- An antibacterial pre-filter to extend the life of the HEPA filter.
- An activated carbon filter for airborne chemicals, cigarette smoke and other gasses and odors.
- A germicidal UV lamp to destroy microorganisms like bacteria, viruses, yeasts and mold spores.
- A programmable sanitizer to neutralize powerful odors like pet odors, tobacco smoke and cooking smells. This optional function does utilize ozone, but it is a programmable setting that you have to choose. Otherwise, the manufacturers report no detectable ozone output and this air ioniser is certified safe in California.
- Lastly, the Surround Air MT-8500 comes with a built-in negative ion generator. They list this ionic air purifier’s negative ion output at 12,000,000/cm3 (trillions per second), and because this unit circulates air in the room to clean it, these ions would be distributed more evenly than the previous two models.
If you’re looking for a good all-in-one air purifier and ionizer without ozone (unless you choose it), with numerous proven air cleaning technologies at a much lower price than most of its competitors, the Surround Air MT-8500 is a great choice.
It does use a bit more energy than the other two negative ionizers reviewed due to its extra functions and is listed at 55 watts of power consumption at the highest settings.
Also, keep in mind that you will eventually have to replace the HEPA filter and UV lamp to keep it running at its best. The manufacturer’s website lists $36 for a replacement HEPA and carbon filter (best changed yearly) and $19 for a replacement UV lamp (which should last 3.5 years).
On the positive side, this is the best air cleaning ionizer if you want to remove airborne allergens in six different and proven ways and circulate the air in your room while you do it.
Many reviewers comment on the cooler feel and much-improved air quality once they turn on the Surround Air MT-8500. Some also say it has reduced their respiratory problems and helped with other health issues and illnesses.
I particularly like that you can program the ozone sanitizer for only when you choose, say in the aftermath of a heavy smoker or wet pets in the house.
The negative ion generation is also impressive, especially as the air is being circulated. Combined with the HEPA filter, carbon filtration and germicidal UV lamp, the Surround Air MT-8500 provides some serious air cleaning for your home or office.
The Surround Air MT-8500 6-in-1 Ionic Air Purifier is my choice for the best all-in-one ionic air purifier with HEPA filter and UV lamp.
There’s more pictures and visual details of how this ionizing air purifier works here on Amazon and the price is surprising given how much technology is packed into this unit.
I hope this air ionizer review has helped you find a proper negative ion generator for your home so you can start enjoying their many health benefits.
Please share it with friends who might be interested in where to buy real negative ionizers and what to avoid when looking for an air cleaner. There’s a lot of supposed ionic air purifiers out there that mainly rely on ozone instead of beneficial negative ions.
After many hours of research on manufacturer’s sites and reading technical specifications, in my opinion, these are the best three ionizers available on Amazon in 2017.
