  • Negative ion generator function
  • True HEPA & activated carbon filters

We were impressed with how the RabbitAir MinusA2 Air Purifier comes with a total of 6 stages for the filtration process. It includes a pre-filter and medium which work to remove the larger particles.

AirHonest Award: Best for Energy Efficiency

Review Highlights: 

  • Night light 
  • Quiet operation
  • Ionizer feature can be turned on/off

If you were after an ionic air cleaner that’s energy-efficient, the OION Technologies B-1000 Ionic Air Purifier would be worth considering. It uses up just 7.5 watts of energy and there are no filters for you to have to replace.

The Ivation Ozone Generator is incredibly effective at purifying the air in spaces that are up to 3,500 square feet. As a result, we recommend it for people interested in removing pollutant particles from larger areas.

Buyers Guide On the Top Ionic Air Purifiers

Best Air Ionizer Benefits

Allergies & Asthma

One of the biggest benefits that people can experience when using air ionizer machines is that they can reduce the number of allergens in the air. This is great for people suffering from allergic symptoms caused by pollen and pets.

Asthmatics are also able to breathe easier due to how ionic cleaning machines can remove pollutant particles from the air so effectively. The cleaner the air in your home, the easier you can breathe.


Dust is one of the main particles causing pollution in most people’s homes. Even if you vacuum and dust your home regularly, there’s always dust that gets moved around into the air for it to eventually settle down again.

Ionic cleaners are great for capturing dust particles that are airborne to make your living environment cleaner.


Mold spores can cause serious health issues if they’re left unchecked. Using ozone air cleaners and air purifiers are fantastic for removing mold particles and preventing harmful bacteria from accumulating in your home.


The best ionic air purifiers and ozone air cleaner are awesome for reducing the intensity of strong smells in homes. Odors that are caused by pets, smoking, chemicals, and cooking can all be minimized to leave your home smelling fresh.

Frequently Asked Questions

Ionizing Air Purifiers Dangerous?

Since air purifiers with ionizing features release ozone, it can lead to potential health risks that are especially troublesome for people suffering with asthma.

Who Should Be Using Ozone Air Cleaners?

Ozone air cleaners can be effective at removing pollutant particles from your air to help you breathe better, which is a great benefit. However, there are some safety concerns that you should be aware of. 

Machines such as the OION Technologies B-1000 and Ivation Ozone Generator are considered to be more pure ionizers. This is because they don’t come with other filtration systems compared to the other options in our review. 

These ionic machines can release ozone which, in substantial quantities, can be harmful, especially for people suffering from asthma. However, as long as the ozone emissions are no more than 0.05 ppm (parts per million), the health risks are more minimal. 

Before purchasing an ozone generator or air purifier with ionic systems, be sure to check how much ozone is emitted. If it’s higher than 0.05 ppm, it could cause asthmatics more problems.

What Is Ionizer Air Purifier?

Ionizing air purifiers are machines that release negatively charged ions which latch onto pollutant airborne particles which include pollen, dust, bacteria, mold, smoke, and pet dander.

The ions with a negative charge attach themselves to pollutant particles that are positively charged. This leads to a bond being formed which causes the particle to become heavy so that it drops closer to the ground. A vacuum can then be used to suck up these particles. Some machines also feature a plate that collects the particles.

If you’re on a tighter budget, you may find that the more inexpensive air purifiers don’t come with ionizing functions that you can turn on or off.

What’s the Best Negative Ion Generator?

The Ivation Ozone Generator is one of the best options to consider if you were interested in a machine that only has ionizing features. It has a fantastic design and can remove odors remarkably well.

You may also want to consider the OION Technologies B-1000 model as it’s incredibly energy efficient and comes with permanent metal filters that can be easily washed.

Are Ion Machine Air Devices More Effective Than HEPA Purifiers?

When it comes to removing smoke, pet dander, and bacteria, ionic filters can be very effective. However, HEPA filters perform better to get rid of pet hair, dust, and can relieve allergy symptoms better. 

So, it depends on the kinds of pollutant particles that you want to remove from your home.

Do Ionic Cleaners Make a Lot of Noise?

This will highly depend on the kind of model that you choose. Many of these machines now come with night time modes that let you have the fan on the lowest setting to produce minimal noise. 

You’ll want to consider using quieter machines if you wanted to set them up in your bedroom so that you can sleep soundly in a cleaner environment. If you’re after a cheap option, it’s more unlikely that it will come with a sleep or night time mode.

Do Collection Plates Make Ionizing Air Purifiers Safer?

Ionizing air purifiers with collection plates aren’t necessary, but they can make the machine more effective at thoroughly getting rid of pollutant particles. This is because air purifiers without collection plates can lead to particles coming lower to the ground where they can eventually rise back up into the air and cause health problems.

The ionizer air purifiers with collection plates provide you with a higher chance of capturing more pollutant particles. We recommend regularly cleaning the collection plate to make sure it can continue working effectively.

Tips On Using Ionic Air Purifier 

  • Be sure to vacuum and regularly clean your home as normal when using ionic air purifiers. This will prevent them from having to work too hard and becoming less effective over time.
  • Check that the exterior and grills of your air purifier don’t accumulate with too much dust. Cleaning it regularly prevents the filters from becoming clogged. 
  • If you have washable filters, make sure that you clean them regularly to ensure they can continue cleaning your air properly. 
  • We recommend measuring the size of the room where you want to install an ionizing purifier before making a purchase. This ensures that you pick a model that’s able to effectively cover the room for cleaning.
