Best Air Ionizers | Ionizer vs Ozone Generator vs HEPA Purifier | Benefits and Dangers

What is the best air cleaner: an ionizer, an ozone generator or a HEPA purifier? We recommend choosing an appliance that combines at least two of these methods of air cleaning. Ionizers send out electrically charged particles into the air to attract contaminants and remove them. Ozone generators produce gas to deodorize and disinfect the space. Air purifiers equipped with a true HEPA filter do a good job at removing dander, dust, and smoke. More importantly, they are highly efficient against allergens, unlike air ionizers which can be harmful to people suffering from allergies.

Poor air quality is a bigger danger than you may think. Worldwide, air pollution accounts for a staggering 4.2 million million deaths per year, in part due to the long-term results of heart disease, stroke, lung cancer, and other fatal respiratory conditions.

While these problems plague overcrowded urban centers, poor air quality isn't limited to cities. Common allergens, viruses, diseases, harmful bacteria, and airborne contaminants are universal.

Air purifiers can help to mitigate the health risks of pollutant exposure. Together, we'll explore the benefits and drawbacks of the most popular purification systems used today.

Ionizers, Ozone Generators, and HEPA: What's the Difference? Explaining the Technology Behind

Some of the most favored air purifiers today include air ionizers, ozone generators, and HEPA filters. Often, the three methods are mixed and matched in one purifying unit to decontaminate the air as fully as possible.

Ionizers remove contaminants by sending out electrically charged particles into the air that help to attract impurities. The process of ionizing is so effective that it can capture extremely small particles, neutralizing pathogens and mitigating smoke.

By contrast, ozone generators produce a fine gas that instantly deodorizes, disinfects, and kills dangerous airborne particulate matter. Like ionizers, ozone generators apply an electrical charge to the air; however, this charge breaks apart oxygen molecules that later bond to form ozone.

Ozone generators are often used in commercial settings since the purification rate is so rapid. That said, ozone is known to be harmful to human health and can aggravate respiratory conditions. These purifiers should only be used in very well-ventilated spaces, away from spaces frequented by pets and humans.

Nowadays, many air purifiers use HEPA, or high-efficiency particulate air, filters. HEPA filters work by forcing air through an extremely fine mesh that traps odors, dander, dust, and smoke.

However, purifiers that merely use HEPA struggle to trap and neutralize VOCs, viruses, bacteria and particulates smaller than 0.3 microns. That's why HEPA is often paired with air ionizing, UV, or ozone-generating tech.

The Benefits and Dangers of Ionizers

Air ionizers are valued for their energy efficiency and fast results. In the span of one to two hours, a small ionizer can improve dangerously polluted conditions to good quality air.

Regardless of their size, ionizers are excellent for targeting smoke, odors, dust, dander, and harmful pathogens. They have the tremendous ability to reduce the effects of seasonal and pet hair allergies within minutes.

Better yet, most air ionizers are completely safe for human use. Ionizers work by populating the air with negatively-charged particles, which are already naturally occurring in the environment. There are no known adverse health effects of circulating ions.

Here's the catch: specific air ionizers that generate ozone may be harmful for human health. Ozone exposure may cause shortness of breath, chest pain, throat irritation, and coughing.

Consumers need to perform sufficient research into the specific air ionizing product they're selecting. Most air ionizing products are certified not to generate ozone.

Review of the Best Air Ionizers

Below, you will find a review of the best air purifier, ozone generator, and ionizer at a price ranging from $80 to $220. You may choose a whisper-quiet ionizer that eliminates bacteria, viruses, mold, and dust, a powerful ozone generator that is suitable not only for homes but also for hospitals and offices or an air purifier equipped with a true HEPA filter that removes the finest particles including allergens.

1. Gideon Mini Plug-in Air Ionizer Air Purifier | Best Ionizer for Mold Removal

With the power of UV light, biological threats are neutralized as soon as they're sucked into the filter. During use, the filter consumes only eight watts of energy. Users love that the two stainless steel filters are permanent, meaning they only need to be cleaned and never replaced.

Moreover, the filter is whisper-quiet, which makes it appropriate for bedrooms, nurseries, and offices. The filter covers a range of up to 150 sq. ft.
