What Are Ozone Air Cleaners?
Ozone air cleaners are often praised for their power and efficacy in eliminating airborne particles that cause odor and sickness. But that doesn’t mean they’re suitable for indoor use.
These air purifiers use a potentially harmful gas – ozone – to purify the air. Ozone reacts with contaminants like viruses and bacteria, cigarette smoke, and mold. But it may affect your lungs too.
What are the health risks you face if you use an ozone air cleaner? Is ozone-safe for use indoors? Should you use it just because it can eliminate indoor and outdoor air contaminants?
Keep reading and we’ll answer all these questions in this blog.
What are the Effects of Ozone on People?
The EPA outlines how harmful ozone can be when it is inhaled. Some effects of ozone exposure include:
- Irritation in the throat
- Chest pain
- Discomfort when taking a deep breath
- Shortness of breath
- Inflamed airways
Particularly for people with lung conditions like asthma, exposure to excessive amounts of ozone can really exacerbate their symptoms. Allergy sufferers will also find their symptoms worsen if they have to breathe air that has both high levels of ozone and allergens.
In fact, air cleaners that produce ozone above California’s ozone emissions limits have been banned in the state of California since 2010.
Even the U.S. Environmental Protection Agency warns against the use of ozone air cleaners. It advises that ozone is largely ineffective at controlling indoor air pollution if its concentrations don’t exceed public health standards.
Simply put, if an ozone air cleaner has pumped out enough ozone to clean the air, it’s harming you too!
Which Air Purifiers Produce Ozone?
There are many ozone air cleaner brands on the market, though they are often called ‘ionizer air purifiers’. Even air purifiers that utilize ultraviolet (UV) light may generate ozone if the lamp is too powerful.
Air purifiers that produce ozone include:
- Ozone air purifiers
- UV light air purifiers
- Ionizer air purifiers
UV Air Purifier Dangers
Some air purifiers use UV light as an alternative to traditional filters, or simply to supplement other filtration methods. UV destroys microorganisms that are exposed to it, rendering them harmless.
However, there are UV air purifier dangers to be aware of.
If the UV light within the air purifier is too powerful, it will actually break apart oxygen molecules as well as contaminants. This can lead to ozone generation – though, to a lesser degree than ozone air cleaners which are designed to generate large amounts of the gas.
Most UV air purifiers use UV-C light, which lies in the 100–280nm range, exactly the range in which there is a risk of ozone being generated.
The Best Non-Ozone Air Purifiers
Want to improve indoor air quality without risking the dangers associated with an ozone air cleaner? There are many non-ozone air purifiers on the market. With filtration methods ranging from mechanical filtration with HEPA filters to Bi-Polar Ionization, they can keep your premises safe from dangerous airborne pollutants without putting your health at risk.
Here are a few alternatives to ozone air purifiers you should consider.
1. HEPA Air Purifiers
High-efficiency particulate air filters (HEPA) trap contaminants and pathogens in the air without emitting harmful gases. These are extended surface filters capable of trapping extremely small particles.
Particles as small as 0.01 micron in size can be trapped by HEPA. It’s why HEPA air purifiers are being used to reduce the transmission of Covid-19.
2. Activated Carbon Purifiers
Activated carbon filters trap airborne particles through absorption. That said, they are less common in air purifiers and more commonly used in water purifications systems.
3. UV Air Purifiers
Yes, UV filters can produce ozone gas under the right circumstances, but not in the same quantities as an ozone air purifier. UV air purifiers purify the air by exposing it to UV-C light (a spectrum of UV). Though effective, they are not suitable for all environments and high airflow rates.
4. Ionization-type Air Purifiers
Ionizers clean the air by attracting airborne dust and particles. However, that is not effective at eliminating odors or fumes, limiting their utility. Another drawback of ionizers is that they can produce ozone gas.
Best Alternative to Ozone Air Purifiers – AirFixture’s CleanAir Tower
- HEPA air filter
- Optional UV, Bi-Polar Ionization
- Durable Steel Construction with powder coat finish
- Tip-over Sensor
- Portable and easy to install
- HEPA filter can make the unit a little larger
- Filter replacement
Portable, durable, and multi-functional, the CleanAir Tower by AirFixture has several unique features that make it the best alternative to ozone air cleaners.
It is an air purification system that can use multiple filtration technologies. It combines Bi-Polar Ionization, UV light, and HEPA filters for the best performance.
Using Bi-Polar Ionization, CleanAir Tower disperses a controlled amount of positive and negative ions into the air that kills airborne particles. The UV filter neutralizes pathogens and contaminants for added protection.
In addition, a HEPA filter can be installed as an option, further enhancing its ability to remove germs and other contaminants from the air. All three air purification systems can be used independently or be used simultaneously.
With a sturdy, full steel construction and powder-coated finish, CleanAir Tower also features a number of safety tools like a tip-over sensor that deactivates the machine if it falls over.
AeraMax 300 Air Purifier by Fellowes
- Automated Smart Sensor
- Certified by the Asthma and Allergy Foundation of America
- Filter replacement costs
If you need an air purifier that removes pollutants for a small-to-medium-sized space, the AeraMax 300 Air Purifier by Fellowes is a good option. It uses a HEPA and carbon filter that neutralizes odors and contaminants indoors.
Effective between 300 to 600 sq. ft., AeraMax 300 is just about adequate for medium-sized rooms, but it does run loud compared to other commercial air purifiers. Additionally, carbon filters require more frequent replacement than mechanical ones, and the cost can add up over time.
- Industrial strength
- Titanium oxide coated HEPA filter
- 2000 sq. ft. of coverage
- Large size
- Impractical for smaller spaces
The Airpura P600+ is a heavy-duty, industrial-strength air purifier that doesn’t utilize ozone. It uses a specialized HEPA filter to filter our particles over a large area – up to 2000 sq. ft. However, its immense cleaning power comes at a cost. The unit is much larger than most air purifiers, which makes it impractical for home use and even for most offices.
Avoid Ozone at Home and in the Office
Ozone air cleaners do still have their uses, especially in industrial or commercial spaces like warehouses, garages, and storage facilities. That way people in the vicinity don’t breathe large concentrations of ozone.
For homes and offices, however, ozone is simply not a risk worth taking. For maximum air purification and minimum risk of ozone gas, choose an air purifier with a HEPA filter.
What you need is an air purifier that:
- Filters air particles
- Destroys germs
- Offers strong airflow
- Compact size
That’s where an air purifier like CleanAir Tower makes all the difference. It offers the benefits of an ionizer without ozone, and can even filter out Covid-19! Its high airflow rate can maintain excellent indoor air quality even in large rooms, without sacrificing portability or comfort. To combat price, size, energy efficiency, and performance – go with Airfixture’s CleanAir Tower.
