Additional Information on Ionizer Air Purifiers

How a Room Air Ionizer Works

If you’re like most people, when you hear the terms “ionic air purifier” or “air ionizer,” you probably imagine a device that operates in a highly scientific and complex manner.

While this may be true to some extent, the way in which these types of air cleaners actually work to purify a room is not as complicated as it may seem.

In fact, the core function of an ionic air purifier relies on basic physics – something we can all easily understand.

Here’s a brief explanation:

  • An ionizer air cleaner operates by sending out negatively charged ions into the air. Airborne pollutants, such as dust, pollen, bacteria, and mold contain positively charged ions. In physics, opposites attract and when these two ions come into contact with each other they form an ionic bond, creating ionized air.
  • Once this bond is made the airborne contaminants become heavier than normal. This weight causes these particulates to fall out of the air and onto the floor. This, in effect, neutralizes the toxins and prevents them from entering into your lungs when you breathe.

As you can see, an ionizer is an air purifier without a filter that cleans the air within a room. It attacks particles at their root location.

The only downside to ionizing air purifiers is that they require you to vacuum the room in order to completely remove the contaminants that settle on the floor.

Fortunately, some ionic air cleaners include an electrostatic collection rod (or plate) that aids in collecting these fallen pollutants.

This collection rod feature is a great addition to have because it helps eliminate the need for regular vacuuming.

The particles stick to the plate as opposed to falling to the floor.

Each of the ionic air purifier reviews we recommend on this page includes this feature.

Why an Ionic Air Purifier is a Great Choice

Best Ionic Air CleanerAs you just discovered, ionic air purifiers use a powerful air cleaning technology that doesn’t require a physical filter to produce clean, fresh air.

It’s this feature alone that makes an air ionizer for home or office use so attractive for many consumers.

Other types of air purifying systems that rely heavily on HEPA filters require regular filter changes throughout the year in order to keep the device operating efficiently.

These costs can really add up.

A HEPA filter is a dense, paper filter. It works by trapping airborne particles that flow through the filter and deliver clean air out the other side.

While these filters are highly efficient, they can be expensive to replace – especially over time. That’s what makes ionic air purifiers a more affordable investment.

As a filterless air purifier, an ionizing air purifier makes for a great long-term investment.

Another important feature to point out is that the best rated ionic air purifiers can remove particulates as small as 0.01 microns.

This is the smallest size of toxins you can strip from the air and includes super-fine dust, bacteria, pollen, pet dander, mold spores and more.

Finally, when shopping for a room ionizing device you’ll often find it packaged with one or more additional air cleaning features.

These upgrades fill in the gaps where ionic technology needs help.

The two most common features include:

  • Carbon Filter – This filter helps to eliminate smoke and odor. It works by absorbing gaseous particles and makes a room smell fresh. While it technically is a physical filter, it is also cheap to replace.
  • Ultra Violet (UV) Light – UV-C radiation is completely safe for humans but destroys viruses and bacteria. It works by breaking up the DNA structure of these particles, which renders them harmless and creates a sterile environment. UV lights last around 10,000 hours and are not expensive to replace.

Now that you know how an air ionizer works and what makes it such a great investment for your home or office, you can now understand why the products recommended above made it to the top of the list.

Are Ionizers Safe?

When some people are looking to buy an ionizer air purifier, a question that often comes to mind is, “Are these products safe?” or “Do I have anything to worry about when using it?”

Since ionic air purifiers emit charged ions into the air as a way to clean it, it’s completely normal to wonder how good or bad they are for your health. Most people have no idea if ions are o.k. to breathe in or not.

Because of this confusion, we thought it would be a good idea to answer that question for those of you who may be having it.

If you’re not worried about this topic, you can skip this section altogether and just choose one of the ionic air purifier reviews above that you like best for your home.

For those of you who are curious, the short answer is “yes” ionic air purifiers are safe as long as the device falls into one of these two categories:

  • It’s an “ionizing” product only and doesn’t have an ozone generator
  • or, it allows you to control the amount of ozone emitted if high levels can be produced

The products we recommended above on this page meet these criteria and are safe for you to use inside your home.

We’ll explain more about why this is true after giving you a little background history on ionizers.

The Controversial Back Story On Ionic Air Cleaners

Back in the late 1990s, a company by the name of Sharper Image came out with a line of top rated ionic air purifiers called the “Ionic Breeze.”

Sharper Image generated a lot of sales by educating the public on how important it was to clean the air inside their homes and by strategically marketing these ionic air cleaners through TV infomercials.

It seemed like everyone was buying an Ionic Breeze for their home or at very least knew someone who had one.

Unfortunately, in the year 2005 Consumer Reports tested the Sharper Image air cleaning product and claimed that it released potentially unhealthy levels of ozone as a by-product into the air, which was essentially making indoor air quality worse for the people who bought it.

After some time, a class-action suit arose against Sharper Image and eventually the company filed for bankruptcy in 2008.

Even until the end, Sharper Image claimed that the testing methods performed by Consumer Reports were flawed and continued to stand by their ionic air cleaner products as being safe for household use.

The EPA Released a Report on Ozone GeneratorsIonizer Air Purifier ReportFast forward a few years and the U.S. Environmental Protection Agency (EPA) began doing its own assessments on air purifiers.

In a report titled Ozone Generators That Are Sold as Air Cleaners: An Assessment of Effectiveness and Health, the EPA brought light to the fact that some manufacturers were mislabeling ozone generators as “air cleaners” as a way to sell more of them to the public.

Those vendors were leading people to believe that these ozone generating devices were always safe to use indoors as a way to reduce airborne pollutants.

Unfortunately, those claims were false and those products were very dangerous to the people who bought them.

The truth is that high concentrations of ozone indoors leads to serious health problems in humans.

Most notably, high ozone levels cause things like:

  • Throat irritation
  • Chest pain
  • Shortness of breath
  • Decreased lung function
  • Higher susceptibility to respiratory infection
  • Aggravation of asthma

Due to the serious health effects that ozone can have on people, federal agencies have established the following set of health standards for what are considered safe levels of exposure for ozone:

  • Healthy Amount = 0 to 0.05 ppm
  • Moderate Concern = 51 to 100 ppm
  • Hazardous Amount = 100+ ppm

With such standards in place, the Food and Drug Administration (FDA) now requires that ozone output for indoor medical devices be no more than 0.05 ppm.

Any higher and the product would be considered unsafe for continuous home use.

What Does This Mean for You and Buying an Air Ionizer?

As we stated earlier, the products we recommend on this page are completely safe for home use.

We’ll explain why this is true below.

(Note: This information only applies to adults who have fully developed respiratory systems. Infants and toddlers will require a special type of air purifier that doesn’t use ionization. You can find information on the best air purifier for baby here.)

The Ivation air cleaner is a combo device that offers you full control over the level of ionization and ozone concentration that it releases into the air.

The ideal setting for this highly rated filterless air purifier is to keep the ozone level as low as possible when people are inside the home.

Whenever the residence is vacant (i.e. you’re at work or the kids are at school), you can safely crank the ozone level all the way up in order to maximize the cleaning power of the device inside your house.

Once you return and cut the ozone feature off (or put it on its lowest setting), the remaining ozone particles in the air will eventually dissipate and go away.

The ionization control on this device can also be adjusted to any level of production. This feature is safe no matter how many ions are produced.

As for the OION and Envion ionic air cleaners, these products only have ionizing capabilities.

Therefore, you don’t have to worry about them emitting unhealthy concentrations of ozone into the air or harming your health.

With that in mind, it’s also important for you to know that these best rated ionic air purifier models do produce a small amount of ozone as a by-product; however, it falls within the < 0.05 ppm range.

As you can see, the ozone ppm level is within the “healthy amount,” as set out by the FDA in the chart above.

Summary On Ionizer Air Purifiers
