The Best Negative Ion Generators May 2021
Here are the top 5 Best Negative Ion Generators for May 2021.
1. Enerzen O-UVC3 Industrial Ozone Generator Air Purifier Sterilizer
Much like other ozone generators, it has potential health hazards depending on the occupants’ conditions.
Product Highlights
The new design that Enerzen implemented into this larger version of their ozone generator produces over 6,000 mg of ozone.
It also houses a larger fan to cover the square footage of up to 4,000 square feet.
The larger fans (40% increase over previous models) help to allow the negative ions to cover more space than ever before.
This unit from Enerzen is capable of handling odor removal of just about anything, including cigarette smoke, pets, chemical fumes, water damage, dust, mold, and mildew.
It’s also incredibly energy efficient to help you save on your utility bill.
Lastly, it has a new timer design for better control, as well as to make it run only when you need it to.
The Good
The positives about the Enerzen Commercial Ozone Generator can go on for a while; it’s such a great overall negative ion generator!
The best features of this model include the large amount of space it can cover, the ability to remove nearly any bad smell, industry-leading customer support, and a washable stainless steel filter, so there’s almost no maintenance required on your part.
The Bad
The only bad thing about this model from Enerzen is that since it’s an ozone generator, you should only use it in unoccupied spaces.
It isn’t an air purifier designed for use in your living room or bedroom due to the effects of ozone.
Pros:
- Wide coverage
- Can eliminate most odors and molds
- Customizable runtime
- Attracts particles efficiently
- Energy-saving
- One-year warranty
Cons:

2. Airthereal MA10K-PRO 10000 mg/h Home Air Ionizer
The Airthereal MA10K-PRO Ozone Generator is, as the name suggests, another ozone-creating negative ion generator.
This unit will produce the largest amounts of ozone per hour for a generator of its size, giving you some of the best bangs for your buck.
Product Highlights
Airthereal touts the MA10K-PRO as a high-capacity ozone generator, and they aren’t exaggerating with that.
This negative ion generator produces and outputs 10,000 milligrams of ozone per hour, which is almost 70% more than the Enerzen Commercial Ozone Generator!
This compact, high-capacity unit has a 20,000-hour service life, which it will spend removing the toughest odors you can throw at it.
Ozone helps remove difficult odors and also prevents the growth of mold within the area.
The Airthereal MA10K-PRO Ozone Generator’s 120-minute timer allows for easy operation to turn on and let it run while you’re not in the area.
The Good
Airthereal wanted to make this one of the highest capacity ozone generators on the market in its price range, and that’s exactly what they did.
The ozone is capable of eliminating all types of odors, and the output of the MA10K-PRO can handle it quickly and efficiently.
Plus, with a three-year warranty, you won’t have to worry about your Airthereal product failing and you being left holding the bag.
The Bad
Similar to other ozone generators, you don’t want to use the Airthereal MA10K-PRO Ozone Generator in the house when you, your family, or your pets may be using the space soon.
Ozone is pretty nasty stuff that you don’t want to be around while it’s running.
Another problem is that the unit has a service life of one year with currently no replacement parts for sale, meaning you’d need to buy a new unit every five years.
Pros:
- Huge capacity
- Can eliminate the toughest odors
- Can run without anyone needing to be nearby
- Industry-leading warranty
- Removes a variety of odors
- Mold-removal capability
- Easy to use
Cons:
- For unoccupied spaces only
- No replacement parts available
- Five-year service life
- POWERFUL OUTPUT: With a maximum output of 10,000 mg/h, an application area of 2,000 sq ft, and a 20,000-hour service life, the MA10K-PRO is more powerful and long-lasting compared to smaller units.
- REMOVE TOUGH ODORS: Ozone is one the most powerful oxidants in the world, which removes tough odors from smoke, cooking, and other sources.
- EASY TO USE: Don't worry about confusing buttons or modes. Simply turn the knob and leave the room, then wait 30 minutes after finishing ozone production to re-enter the room.
- SIMPLE TIMER: Use the control knob to adjust the time from 0-120 minutes or use the hold function to run the ozone generator continuously until you shut the unit off.
- WORD OF WARNING: All ozone generators should only be used in unoccupied spaces. Don't let people or pets enter the area until 30 minutes after ozone generation ends. Not available for sale in...

3. Airthereal Commercial Ozone Generator
The second consecutive product from this manufacturer, the Airthereal MA5000 Ozone Generator comes in as the third product in our list.
Aithereal is one of the top names in the negative ion generator industry, as you can see, with it claiming two out of the five spots on this list.

It also uses an incredibly low amount of energy, and it’s affordable to use.
The Good
With its 5,000 mg/hour of ozone production, the Airthereal MA5000 can handle almost as much air as the Enerzen product.
Unlike the other option from Airthereal, the MA5000 includes replaceable ozone plates rather than just having a five-year service life.
It’s also easy to move and take anywhere you need it.
The Bad
This unit from Airthereal should only be used in unoccupied spaces like all ozone generators, so it isn’t made for purifying the air in your family room or anything.

Buyers Guide
Even if you’ve already narrowed down your search by considering the products we reviewed above, there are a few things you should keep in mind while shopping.
You must understand the important features of negative ion generators, such as:
Ozone Generation
You’ll want to know if the generator outputs ozone as the working agent.
If so, as mentioned, you must keep in mind that you shouldn’t use it anywhere that people and/or pets will be using.
These are used for commercial properties or homes when you’ll be away for a while.
Filters and Plates
Consider how the filters and ozone plates within the generator need to be maintained.
Some options will have filters and plates that you can clean and re-use, while others offer replacements.
Lastly, some models require you to purchase an entirely new generator once the filters and plates reach their service lives.
Build or Durability
As with any product, you want something that will last. Thus, don’t go for items made of low-quality plastic that might fall apart the first use.
Opt for high build quality that will last you for years.
FAQs
What is a negative ion generator?
A negative ion generator is another name for an air ionizer. Negative ion generators purify the air that travels through and around them through the process of ionization.
Ionization causes particles to be attracted to other surfaces instead of stay in the air.
Do negative ion generators really work?
Negative ion generators work by causing airborne particles to become negatively charged and naturally stick to other surfaces rather than being in the air.
This does work as the particles will be stuck on the other surfaces and no longer be freely floating in the air.
Can negative ions be harmful?
In general negative ions are typically seen as being beneficial.
When it comes to negative ion generators, many of them generate ozone, which can be harmful to both humans and pets.
As such, you should not use ozone generators in occupied spaces or areas that will be occupied after a few hours of using the generator.
Do negative ions kill viruses?
Negative ions do not necessarily kill the viruses by themselves.
All they do is cause the virus to become negatively charged, so the viruses get attracted to the surface rather than floating in the air.
This process halts the spread of the virus and can help prevent viruses from entering your body through the air.
Which is better—air purifier or ionizer?
Both types of air filtration systems work well and can be used to great effect. There isn’t one that is better than the other.
Again, with ozone generators, you don’t want to use them in an occupied or soon-to-be occupied space due to the harmful effects of ozone.
Decide which type of purification is best for yourself and your situation; you’ll be happy either way!
Our Final Recommendation
After you’ve kept all of the important things in mind, such as if it uses ozone or not, what the required maintenance is, and the construction quality, it’s time to make a decision.
The best of the best negative ion generator for us is the Enerzen Commercial Ozone Generator.
It can sterilize up to 4,000 square feet with an industry-leading 180-minute timer for customized use.
That said, no matter which option you end up going with, we’re confident that you’ll be happy with any of the negative ion generators on this list.
