Factors to Consider

The following is a list of factors to consider when buying air ionizers:

Purification range:

The purification range is the first factor you should consider when buying an air ionizer. The general standard range in the industry is about 500 square feet.

The first model in a review can purify a range that reaches out to 3,500 square feet, which is pretty enormous.

This type of range is great for people looking to purify medium to large and open areas. Other models on the market only purify a range of about 300 square feet or so, which is still plenty of range for small to medium rooms.

This is the most important factor to consider because if you buy the incorrect range for your needs the model will simply not work for you.

Filter style:

The next factor to consider is the filter style of the models you’re considering. Some of the models have removable filters, some of which are washable and others that require replacement. These are certainly less ideal than models that don’t require filter replacement.

Other models on the list simply operate without a filter at all, removing the need for you to worry about replacing or cleaning the unit. Still, others have complex filter setups, combining multiple filter types and sanitization methods, such as UV light.


A third factor to consider is the various modes the ionizers can operate on. For instance, some models come with sleep modes and automatic operating modes.

Other models have specific ozone modes that are intended to eliminate odors and musty smells.

Of course, some models have more features than others, but that doesn’t always mean it’s a better model or that those features are all necessary.

By knowing exactly what you need from your ionizer, you can find the best all-encompassing value package for your intended use.


A final factor to take into consideration is whether or not a unit comes with a warranty or money-back guarantee. Of course, having a warranty doesn’t guarantee the unit is worth its salt. It does mean that you can have it replaced or get your money back should anything go wrong.


Are ionic air purifiers safe?

Ionic air purifiers are certainly safe in moderation, just like anything. They work by emitting negative ions that attach to the positively charged particles in the air, causing them to be too heavy to remain in the air.

The only thing to worry about is overexposure to ozone, depending on the model you have or choose to buy.

There is some well-reasoned speculation that too much ozone exposure is harmful to your health, in addition to the harm it causes to the environment. When used in moderation, ionic air purifiers are safe and can even be helpful to your health.

How does UV light help to clean and purify the air?

UV light helps to purify the air because when bacteria or other microbes are exposed to certain UV light sources, their DNA is damaged, preventing reproduction. This ensures that the bacteria won’t spread and become more of a problem in your air.

The models that utilize this UV light system often combine it with multi-layered filters to create the highest quality air for you.

Are standalone or wall socket models better?

Let’s first be clear, all models are socket models in the sense that they need to be plugged into work. The standalone models, however, are often considered more versatile as they’re able to move to specific spots. The wall socket models are a bit limiting in the sense that you can only have them in specific areas of your home or space with outlets.

However, depending on your setup, wall socket models may work for you just fine. So, as for which is better, that’s up to how you intend to use the unit.


In conclusion, the Ivation Ozone Generator Air Purifier is the best model on the market for keeping your air healthy. This model can purify a range of about 3,500 square feet, which is by far the largest range on the list. It also sports a 24/7 dust collection feature and adjustable fan speeds.

If this model is out of range for you, whether price-wise or too much range, there is the OION Technologies B-1000. This unit catches particulates as small as 0.01 microns and utilizes a UV light sanitation system with its filter to guarantee clean air.

No matter the unit you’re considering, be sure that it’s going to accomplish all of the things you’re hoping to use it for.

Having read through these reviews, you’re more than capable of making a conscientious decision when it comes to the perfect ionizer for your needs. So, what are you waiting for? Get your new ionizer and healthy air circulating today!
